Table 1 Safety signs

Sign

Description

Circuit or electricity hazards are present. Only H3C authorized or professional server engineers are allowed to service, repair, or upgrade the server.

WARNING WARNING!

To avoid bodily injury or damage to circuits, do not open any components marked with the electrical hazard sign unless you have authorization to do so.

Electrical hazards are present. Field servicing or repair is not allowed.

WARNING WARNING!

To avoid bodily injury, do not open any components with the field-servicing forbidden sign in any circumstances.

The RJ-45 ports on the server can be used only for Ethernet connections.

WARNING WARNING!

To avoid electrical shocks, fire, or damage to the equipment, do not connect an RJ-45 port to a telephone.

The surface or component might be hot and present burn hazards.

WARNING WARNING!

To avoid being burnt, allow hot surfaces or components to cool before touching them.

The server or component is heavy and requires more than one people to carry or move.

WARNING WARNING!

To avoid bodily injury or damage to hardware, do not move a heavy component alone. In addition, observe local occupational health and safety requirements and guidelines for manual material handling.

The server is powered by multiple power supplies.

WARNING WARNING!

To avoid bodily injury from electrical shocks, make sure you disconnect all power supplies if you are performing offline servicing.

 

Safety information

Familiarize yourself with the safety information in the following sections before troubleshooting the server.

General operating safety

To avoid bodily injury or damage to the server, follow these guidelines when you operate the server:

·     Only H3C authorized or professional server engineers are allowed to install, service, repair, operate, or upgrade the server.

·     Place the server on a clean, stable table or floor for servicing.

·     Make sure all cables are correctly connected before you power on the server.

To ensure good ventilation and proper airflow, follow these guidelines:

·     Install blanks if the following module slots are empty:

¡     Drive bays.

¡     Fan bays.

¡     PCIe slots.

¡     Power supply slots.

·     Do not block the ventilation openings in the server chassis.

·     To avoid thermal damage to the server, do not operate the server for long periods in any of the following conditions:

¡     Access panel open or uninstalled.

¡     Air baffles uninstalled.

¡     PCIe slots, drive bays, fan bays, or power supply slots empty.

·     To avoid being burnt, allow the server and its internal modules to cool before touching them.

Electrical safety

WARNING

WARNING!

If you put the server in standby mode (system power LED in amber) with the power on/standby button on the front panel, the power supplies continue to supply power to some circuits in the server. To remove all power for servicing safety, you must first press the button, wait for the system to enter standby mode, and then remove the power cords from the server.

 

To avoid bodily injury or damage to the server, follow these guidelines:

·     Always use the power cords that came with the server.

·     Do not use the power cords that came with the server for any other devices.

·     Power off the server when installing or removing any components that are not hot swappable.

Battery safety

The server's system board contains a system battery, which is designed with a lifespan of 3 to 5 years.

If the server no longer automatically displays the correct date and time, you might need to replace the battery. When you replace the battery, follow these safety guidelines:

·     Do not attempt to recharge the battery.

·     Do not expose the battery to a temperature higher than 60°C (140°F).

·     Do not disassemble, crush, puncture, short external contacts, or dispose of the battery in fire or water.

·     Dispose of the battery at a designated facility. Do not throw the battery away together with other wastes.

Power source recommendations

Power instability or outage might cause data loss, service disruption, or damage to the server in the worst case.

To protect the server from unstable power or power outage, use uninterrupted power supplies (UPSs) to provide power for the server.

Rack mounting recommendations

To avoid bodily injury or damage to the equipment, follow these guidelines when you rack mount a server:

·     Mount the server in a standard 19-inch rack.

·     Make sure the leveling jacks are extended to the floor and the full weight of the rack rests on the leveling jacks.

·     Couple the racks together in multi-rack installations.

·     Load the rack from the bottom to the top, with the heaviest hardware unit at the bottom of the rack.

·     Get help to lift and stabilize the server during installation or removal, especially when the server is not fastened to the rails. As a best practice, a minimum of four people are required to safely load or unload a rack. A five person might be required to help align the server if the server is installed higher than check level.

·     For rack stability, make sure only one unit is extended at a time. A rack might get unstable if more than one server unit is extended.

·     Make sure the rack is stable when you operate a server in the rack.

·     To maintain correct airflow and avoid thermal damage to the server, use blank panels to fill empty rack units.

ESD prevention

Electrostatic charges that build up on people and tools might damage or shorten the lifespan of the system board and electrostatic-sensitive components.

Preventing electrostatic discharge

To prevent electrostatic damage, follow these guidelines:

·     Transport or store the server with the components in antistatic bags.

·     Keep the electrostatic-sensitive components in separate antistatic bags until they arrive at an ESD-protected area.

·     Place the components on a grounded surface before removing them from their antistatic bags.

·     Avoid touching pins, leads, or circuitry.

Grounding methods to prevent electrostatic discharge

The following are grounding methods that you can use to prevent electrostatic discharge:

·     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

·     Take adequate personal grounding measures, including wearing antistatic clothing and static dissipative shoes.

·     Use conductive field service tools.

·     Use a portable field service kit with a folding static-dissipating work mat.

Collecting fault information

Collecting operating system logs

IMPORTANT

IMPORTANT:

·     Obtain a written consent from the customer before collecting operating system logs.

·     The collected operating system logs are only used for hardware troubleshooting. For operating system issues, contact the operating system manufacturer.

 

 

NOTE:

For how to collect logs for other types of operating systems, contact Technical Support.

 

Collecting logs for a Windows operating system

·     If no blue screen fault occurs, perform the following tasks:

a.     Open the Computer Management window.

b.     Select System Tools > Event Viewer.

c.     Select Windows Logs > System > Save All Events As to export the logs to a file.

·     If a blue screen fault occurs, perform the following tasks:

a.     Take a screenshot or photo of the blue screen fault information.

b.     Restart the operating system, and then collect all files in path C:\WINDOWS\Minidump\.

Collecting logs for a Linux operating system

·     If the Linux system has the sosreport tool, perform the following tasks:

a.     Log in to the Linux CLI as the root user.

b.     Execute the sosreport command to collect all Linux logs, which might cost several minutes.

The logs will be saved to log file sosreport-localhost-ID-YYYY-MM-DD@HH-MM-SS.tar.xz in directory /var/tmp.

·     If the Linux system does not have the sosreport tool, collect all files in directory \var\log and directory /var/crash.

Collecting logs for a VMware operating system

·     If no purple screen fault occurs, perform either of the following tasks:

¡     Select Host > Monitor > Logs on vSphere Web Client, and then search for and export the system logs.

¡     Log in to the ESXi Server Console CLI as the root user, and then execute the vm-support command to collect all VMware logs, which might cost several minutes.

The logs will be saved to log file esxsupport-YYYY-MM-DD@HH-MM-SS.tgz in directory /var/tmp.

·     If a purple screen fault occurs and a warm reboot has been performed, perform the following tasks:

a.     Log in to the ESXi Server Console CLI as the root user.

b.     Execute the vm-support command to collect all VMware logs, which might cost several minutes.

The logs will be saved to log file esxsupport-YYYY-MM-DD@HH-MM-SS.tgz in directory /var/tmp.

·     If a purple screen fault occurs and the fault information is retained, perform the following tasks:

a.     Take a screenshot or photo of the purple screen fault information.

b.     Press Alt and F12 simultaneously to display the VMkernel log, and then take screenshots or photos of the logs generated when the fault occurred.

You can press Alt and PageUp or Alt and PageDown simultaneously to scroll the screen and view more logs.

c.     Perform a warm reboot on the operating system.

d.     Execute the vm-support command to collect all VMware logs, which might cost several minutes.

Collecting HDM SDS logs

Smart Diagnose System (SDS) logs include server logs (such as event logs, operation logs, and internal logs), hardware information, and fault diagnosis information. You can learn about the server running state through SDS logs.

Restrictions and guidelines

·     Simultaneous log downloading by multiple users is not supported.

·     An .sds file saves log entries in UTC, but HDM uses the date and time synchronized from an NTP server. If you download log entries for a specific period, HDM converts the specified start time and end time into UTC, which might introduce time differences.

Procedure

1.     Log in to HDM. For more information, see HDM User Guide.

2.     Open the log collection page.

3.     Download the entire log or log entries for a period:

¡     To download the entire log, click Download entire log.

¡     To download the log entries for a period, specify the start time and end time in the Download specified log area.

4.     (Optional.) Add contact information, including the name, phone number, and email address.

5.     Click Download log to download the log.

6.     Save the .sds file to the local disk.

7.     To parse SDS logs, contact Technical Support.

Collecting HDM screen recording information

HDM records the server status upon occurrence of severe operating system events, including crash, restart, and shutdown. You can replay these videos to analyze or troubleshoot the recorded events. On the video replay page, you can play and download the recorded videos.

Restrictions and guidelines

If the operating system was in sleep state when the event occurred, HDM displays a no signal message in place of the video.

Procedure

1.     Log in to HDM. For more information, see HDM User Guide.

2.     Open the Screenshots & Videos page.

3.     To play a video, click the video in the Video files section.

4.     To download a video, click Download after the video is loaded.

Collecting storage controller configuration through the operating system

To obtain the manufacturer of a storage controller, contact Technical Support.

Diagnosing and locating faults

Restrictions and guidelines

Before you operate devices on the site, contact the customer for permission.

Before you operate storage media, notify the customer to contact H3C Technical Support to migrate or back up service data.

Follow these guidelines when you troubleshoot and locate faults:

·     Check for external faults prior to internal faults. For example, check the power supply, network cables, power cords, peer device status, and server location before you check the hardware status and OS operation status.

·     Evaluate the overall status of the server on HDM and observe the server health LED before you check specific hardware or software components based on the symptom and logs. For unrecognized hardware, bandwidth decrease, or CRC errors, list all possible failure points on the topology and then determine the troubleshooting scheme.

·     Resolve issues in descending order of severity.

·     Acknowledge alarms in descending order of severity.

·     Analyze hardware log and OS log in combination.

·     Minimize the test scope and use cross validation to resolve frequently occurred faults such as power-on failure:

¡     Install components one by one according to "Breaking server down to the minimum hardware configuration" to locate faulty hardware.

¡     Replace components of a failed server one by one to locate a faulty component.

General troubleshooting workflow

1.     Make preparations:

a.     Verify that the server has stable power supply and in an environment that can ensure correct operation of the server. Make sure the environment meets the space, ventilation, temperature, humidity, hygiene, rack height, and grounding requirements in the server usage manual.

b.     Remove peripherals from the server, such as optical drives, USB flash drives, and external hard drives.

c.     Prepare tools and software for troubleshooting as described in "Preparing software utilities" and "Preparing hardware utilities."

2.     Collect logs as described in "Collecting fault information" and record the time, frequency, and alarm screenshot for the fault.

3.     Log in to HDM and check the overall operation status of the server.

4.     Check the status of each subsystem as instructed to locate the fault.

5.     Check HDM event log to identify the faulty hardware.

6.     If the faulty hardware cannot be located, shut down the server, disconnect the power cord, and verify that all components are correctly installed and connected inside the chassis.

7.     Troubleshoot the fault as described in "Troubleshooting hardware issues" and "Troubleshooting software issues."

8.     If the issue persists, collect HDM SDS log as described in "Collecting HDM SDS," record the time, frequency, and alarm screenshot for the fault, and contact Technical Support.

Troubleshooting hardware issues

General hardware issues

New component issues

Symptom

After you install a new component or use a new component to replace the old component, the server fails to start up or the installed component cannot operate normally.

Possible causes

·     The server is not compatible with the component.

·     The component is not installed in place.

·     The firmware or driver version of the component is too low.

·     The component is faulty.

Solution

To resolve the issue:

1.     Use the OS compatibility query tool available from Query tool for server and component compatibility to verify that the server is compatible with the component.

2.     Verify that the component is installed in place and the cables are connected correctly and securely.

3.     Update the firmware and driver of the component to the latest version and verify that the system can identify the component.

4.     Install the component to other servers that are operating normally to check whether the component is faulty.

5.     If the server cannot start up, use the minimum hardware configuration in the server. After the server starts up normally, install the component in the server to check whether the component is faulty. If the server fails to start up, replace the component. If the server can starts up normally, the component is normal. For information about minimum hardware configuration, see "Breaking server down to the minimum hardware configuration."

6.     If the issue persists, contact Technical Support.

Third-party component failure

Symptom

The server cannot identify the third-party component or the third-party component cannot operate normally.

 

 

NOTE:

A third-party component is a component that is purchased from other companies than H3C or a component that is purchased from H3C but not compatible with the server. For compatibility between the server and component, use the query tool available from Query tool for server and component compatibility.

 

Possible causes

Port WWPN on an FC HBA is recognized by the storage device, but the server fails to recognize the LUN

Symptom

As shown in Figure 130, an FC HBA is installed on the server. The FC HBA connects to a storage device through an FC switch. The storage device recognizes the port WWPN on the FC HBA, but the server fails to recognize the LUN.

Figure 130 Storage network connection diagram

 

Possible causes

·     The firmware and driver versions of the FC HBA are too low, or incompatible with the operating system.

·     The operating system does not recognize the LUN and needs to rescan the FC link.

·     The storage device is faulty.

·     The FC link is faulty.

Solution

To resolve the issue:

1.     Check and be sure that the FC HBA is installed with the latest driver and firmware versions compatible with the operating system. For the driver and firmware versions compatible with the operating system, use the query tool available from Query tool for operating system compatibility.

2.     Collect operating system logs and FC HBA logs and search for information printed by the FC HBA driver in the logs, and determine whether logs about link establishment and LUN identification exist.

¡     If such logs exist, the link was established and the LUN was recognized previously. Go to step 3 to scan and identify the storage link again.

¡     If such logs do not exist, no link has been established. Check and be sure that the FC link between the FC HBA card and the switch is normal. For example, replace or swap the cable or transceiver module with a known functional one to determine whether a component faulty. If a component is faulty, replace it. If the issue is not caused by the hardware components on the link or the issue persists after component replacement, contact Technical Support.

Figure 131 Identifying the logs about link establishment and LUN recognition

 

3.     Execute the echo 1 > /sys/class/fc_host/host<number>/issue_lip command to scan the link. Number represents the interface number. For the relations between the interface numbers and FC HBA port, identify host# from the system logs. As shown in Figure 132, interface 3b:00.0 matches fc_host number 4.

Figure 132 Matching relations between number and FC HBA port

Figure 133 Rescanning the FC link

 

4.     Contact the storage device or OS vendor for troubleshooting. If collaborative analysis with the server side is required, collect logs and contact Technical Support.

Some of the multiple LUN links fail

Symptom

As shown in Figure 134, an FC HBA is installed on the server. The FC HBA connects to a storage device through multiple FC switches. Some of the LUN links fail

Figure 134 Multiple LUN links

 

Possible causes

·     The firmware and driver versions of the FC HBA are too low, or incompatible with the operating system.

·     Multi-path driver failure in the operating system.

·     The switch is faulty.

·     The storage device is faulty.

·     A hardware component on the FC link, such as the FC HBA, cable, or transceiver module, is faulty.

Solution

To resolve the issue:

1.     Check and be sure that the FC HBA is installed with the latest driver and firmware versions compatible with the operating system. For the driver and firmware versions compatible with the operating system, use the query tool available from Query tool for operating system compatibility.

2.     View port error statistics on the switch to check whether errors occur on the FC link between the FC HBA and the storage device. If an error occurs, the FC link is abnormal. Go to step 3. If no error occurs, go to step 4.

For example, execute the porterrshow command on the Brocade switch to check related statistics.

¡     crc_err as shown in Figure 135 indicates the CRC errors of data frames. If a data frame is damaged, the receiver will detect the value inconsistency, and the error count increases. If the value is 0, the data frames are not damaged. A hardware component on the FE link might be faulty.

¡     enc_out as shown in Figure 135 indicates errors caused by non-data frame issues, typically cable quality or endpoint issues. In addition, the ups and downs of ports caused by the restart of the endpoint might also cause increase of the enc_out value. If the value is 0, no errors occur on the data frames. If the value is not 0, the cable might be faulty.

As shown in Figure 135, the crc_err and enc_out parameters of port 0 are both 0, indicating that the hardware components on the FC link are operating correctly. Go to step 4. If the crc_err and enc_out parameter values are not 0, go to step 3.

Figure 135 Viewing the port error statistics for the FC link between the FC HBA and storage device

 

3.     If a hardware component on the FC link is faulty, replace the faulty component. For example, you can replace or swap the cable or transceiver module with a known functional one to determine whether the cable or transceiver module faulty. If the issue persists after the faulty component is replaced or the issue is not caused by the hardware component on the FC link, contact Technical Support.

4.     Contact the storage device or OS vendor for troubleshooting. If collaborative analysis with the server side is required, collect logs and contact Technical Support.

1.     Check and be sure that the FC HBA is installed with the latest driver and firmware versions compatible with the operating system. For the driver and firmware versions compatible with the operating system, use the query tool available from Query tool for operating system compatibility.

2.     Compare the I/O performance between the server and the storage device to determine whether the FC link causes low LUN read and write performance.

a.     Compare the I/O delays and concurrent operations on the server with those on another server with the same configuration. Determine whether the server provides satisfactory I/O performance. If the server provides satisfactory I/O performance, go to step a. If the server's I/O performance is not satisfactory, contact Technical Support to troubleshoot the I/O performance.

For example, you can use the iostat command in the Linux system to view the I/O performance.

-     r/s—Number of reads completed per second.

-     w/s—Number of writes completed per second.

-     await—Average waiting time for each I/O request.

-     r_await—Average wait time for each read request.

-     w_await—Average wait time for each write request.

Figure 137 Viewing the I/O delays and concurrent operations

 

a.     Check on the server whether the I/O performance from the FC HBA to the storage device reaches the expected performance. Compare the local I/O performance obtained in 2.a with this performance to determine whether the performance degrades. If the performance degrades, the link between the FC HBA and the storage device is faulty, go to step 3. If the performance does not degrade, contact Technical Support to determine whether an application issue causes performance degradation.

For example, in the Linux operating system, execute the dd command to test the I/O performance.

Figure 138 Checking whether the I/O performance from the FC HBA to the storage device reaches the expected performance

 

3.     Log in to the switch to check whether errors occur on the FC link between the FC HBA an the storage device. If an error occurs, the FC link is abnormal, go to step 4. If no error occurs, go to step 5.

For example, execute the porterrshow command on the Brocade switch to check related statistics.

¡     crc_err as shown in Figure 139 indicates the CRC errors of data frames. If a data frame is damaged, the receiver will detect the value inconsistency, and the error count increases. If the value is 0, the data frames are not damaged. A hardware component on the FE link might be faulty.

¡     enc_out as shown in Figure 139 indicates errors caused by non-data frame issues, typically cable quality or endpoint issues. In addition, the ups and downs of ports caused by the restart of the endpoint might also cause increase of the enc_out value. If the value is 0, no errors occur on the data frames. If the value is not 0, the cable might be faulty.

As shown in Figure 139, the crc_err and enc_out parameters of port 0 are both 0, indicating that the hardware components on the FC link are operating correctly. Go to step 4. If the crc_err and enc_out parameter values are not 0, go to step 5.

Figure 139 Viewing the error statistics on the FC link from the HBA to the storage device

 

4.     If a hardware component on the FC link is faulty, replace the faulty component. For example, you can replace or swap the cable or transceiver module with a known functional one to determine whether the cable or transceiver module faulty. If the issue persists after the faulty component is replaced or the issue is not caused by the hardware components on the FC link, go to step 5.

5.     Check whether the storage device performance degrades. For example, use a known functional server to check whether the storage device is operating correctly. If the storage device is faulty, contact the storage device manufacturer for analysis. Otherwise, collect system logs and FC HBA logs and contact Technical Support.

Software and configuration utilities

Relationship among software and configuration utilities

As shown in Figure 163, the software and configuration utilities relate to each other as follows:

·     Internally, HDM communicates with BIOS, iFIST, and components (including firmware of components) to monitor and manage the server. Externally, HDM communicates with management tools, O&M systems, and users.

·     BIOS boots the OS and iFIST and reports various messages to HDM.

·     iFIST can perform RAID configuration, OS auto installation, and hardware diagnostics.

·     FIST can work with REPO to bulk upgrade HDM, BIOS, component firmware, and driver.

·     U-Center and FIST can bulk manage servers based on HDM, FIST SMS, and iFIST. The FIST SMS is a program on the OS used to support some functions of FIST and HDM.

Figure 163 Relationship among software and configuration utilities

 

BIOS

Basic Input/Output System (BIOS) is stored on ROM and is a program a computer's microprocessor uses to start the computer system after it is powered on. Located between the computer's operating system (OS) and hardware components, BIOS initializes hardware and makes preparations for the OS to run.

When a server fails, you can troubleshoot problems by using BIOS:

·     When a problem occurs during startup, you can view POST codes reported by BIOS to HDM and locate the problem according to the description of POST codes in the HDM user guide.

·     On the BIOS Setup page, view information about processors, memory, and access devices and configuration options. Configuration options can be viewed and exported through HDM.

·     In the UEFI Shell CLI environment, BIOS supports UEFI native Shell commands. These commands can be used to execute EFI programs, load EFI drivers, and boot OSs.

·     If the problem cannot be resolved, collect BIOS logs and contact technical support. You can collect BIOS logs through the BIOS serial port or the IPMI SOL function. Using the debug mode can obtain detailed log information.

Viewing POST codes

POST codes contain information about all states of BIOS startup and error codes. BIOS reports POST codes to HDM. When the server experiences problems during startup, you can examine the POST codes in HDM as shown in Figure 164 to help analyze the cause of problems.

·     For more information about POST codes, see the POST code section in the HDM user guide.

Figure 164 POST codes

 

Exporting BIOS configuration

HDM supports exporting the current configuration of BIOS, as shown in Figure 165.

When a server fails, you can export the current configuration of BIOS. On another normal server, install the same version BIOS and export the default BIOS configuration. Compare the two BIOS configurations for differences to identify the cause of the failure.

Figure 165 Exporting BIOS configuration

 

Starting UEFI Shell in BIOS Setup

1.     Set EFI Shell Boot to Enabled, as shown in Figure 166.

Figure 166 Setting EFI Shell Boot

 

2.     After restart, enter F7 to enter Boot Menu and select UEFI: Built-in EFI Shell, as shown in Figure 167.

Figure 167 Selecting UEFI: Built-in EFI Shell

 

3.     The UEFI Shell page is displayed, as shown in Figure 168. You can obtain supported Shell commands by using the help command.

Figure 168 UEFI Shell page

 

Obtaining BIOS logs

Enabling the Debug mode

Enabling the Debug mode allows you to obtain detailed BIOS logs. This operation will extend the startup time and is typically used for troubleshooting.

The Debug mode is disabled by default. To enable the Debug mode, access the BIOS Setup > Platform Configuration > Miscellaneous Configuration, and set Debug Mode to Enabled, as shown in Figure 169.

Figure 169 Setting Debug mode

 

Collecting BIOS logs

You can use the following methods to collect BIOS logs:

·     Connect the BIOS serial port, use a serial port client tool such as PuTTY to configure the BIOS serial port, and save BIOS logs during startup. For the position of the BIOS serial port, see the corresponding user guide.

·     Save BIOS logs by using the following command: ipmitool.exe –I lanplus –H { hdm_ip } –U { username } –P { password } sol activate > debug.txt

 

 

NOTE:

Servers using Hygon processors do not support using IPMI commands to collect BIOS logs.

Remote maintenance through HDM

The following describes how to handle server failures remotely through HDM:

1.     Log in to the HDM Web interface to determine the device running status. The following information is displayed on the homepage:

¡     Basic status.

¡     Basic information.

¡     Server power.

2.     If the basis status is abnormal, check whether event logs are generated or whether a sensor is in abnormal state.

3.     Check whether information about install hardware is displayed completely.

4.     Perform the following operations as required (if necessary, contact technical support):

¡     Restore HDM factory defaults.

¡     Restart HDM.

¡     Update firmware for HDM, BIOS, CPLD, and PSU.

¡     Import or export the configuration of HDM, BIOS, and RAID.

FIST

Fast Intelligent Scalable Toolkit (FIST) is a server companion tool used to rapidly and flexibly configure servers and instruct users to use servers.

FIST can run on a PC or server. As a bulk server management and maintenance tool, FIST can help enterprises better manage, monitor, and update systems and query information.

As a built-in tool of the AE module, FIST not only manages local cabinets but also manages other cabinet servers, rack servers, and switches in the network. FIST is applicable to hybrid IT infrastructure and cluster management.

FIST provides the following functions:

·     Device management—Centrally manages racks, servers, and switches, including adding devices, view device information, and other common device management operations.

·     Template management—Uses templates to configure BIOS, HDM, RAID, and OS parameters for devices to come online quickly.

·     Deployment—Bulk applies configuration templates for racks and servers and updates firmware and drivers.

·     Monitoring and alarm—Monitors the server status and generates alarms for quick troubleshooting.

·     Tool set—Provides common tools used for servers.

·     System setting—Provides system settings and management functions for the FIST service end.

iFIST

Integrated Fast Intelligent Scalable Toolkit (iFIST) is an intelligent deployment tool used to deploy standalone servers. After the server is started and completes initialization, you can access iFIST as prompted without installing it.

iFIST provides a simple interface for you to complete RAID settings, OS auto installation, server diagnostics, and log download.

iFIST is applicable to local management of standalone servers. When you cannot log in to HDM remotely, you can use a display, a keyboard, and a mouse to connect to the server and use iFIST for convenient in-band server deployment.

HDM Redfish API

Redfish® is a DMTF's standard based on RESTful. It supports both HTTP and HTTPS. Each Redfish request is sent in UTF-8-coded JSON format and will receive a resource result. This standard is regarded as the next-generation data center management standard, because it reduces development complexity, is easy to implement and use, and is scalable.

HDM supports managing servers through Redfish APIs. Redfish APIs allows you to simplify server configuration, view server component information, monitor server status, and control servers remotely.

For more information about Redfish and Redfish APIs, access the H3C website.

HDM IPMI

Intelligent Platform Management Interface (IPMI) is a standard for server management systems. Independent of the processor, BIOS, and OS, IPMI can centrally manage servers of different types.

In IPMI, the Baseboard Management Controller (BMC) is the core controller. IPMI interacts with the BMC to perform management.

IPMI provides the following out-of-band management and monitoring function:

·     Asset management.

·     Fault monitoring.

·     Log record.

·     Recover control.

For IPMI commands supported by HDM, see H3C HDM IPMI Basics Command Reference on the H3C website.
