2. Examine the LED for the Ethernet port to verify that the port is operating correctly. For more information about the LEDs, see H3C SR6602-I[IE] AI Series ICT Converged Gateways Hardware Information and Specifications.

NOTE:

After connecting the device to the network, you can use the ping or tracert command to verify network connectivity of the device. For more information about the commands, see the command references for the device.

Connecting optical fibers

WARNING!

Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into beams or view directly with optical instruments when the device is operating.

CAUTION:

· Never bend an optical fiber excessively. The bend radius of an optical fiber must be not less than 100 mm (3.94 in).

· Keep the fiber end clean.

· To connect an optical fiber to a fiber port, make sure the fiber connector matches the transceiver module.

· Before connecting an optical fiber, make sure the received optical power does not exceed the upper receive power threshold of the transceiver module. If the threshold is exceeded, the transceiver module might be damaged.

· To connect an optical fiber to a fiber port, first install a transceiver module in the fiber port and then connect the optical fiber to the transceiver module.

· Insert a dust plug into any open fiber port.

To connect an optical fiber:

1. Remove the dust plug from the fiber port.

2. Pivot the clasp of the transceiver module up to catch the clip on the top. Hold the two sides of the transceiver module and insert it slowly into the fiber port.

3. Remove the dust cap from the optical fiber connector, and use dust-free paper and absolute ethanol to clean the end face of the fiber connector.

4. Identify the Rx and Tx ports on the transceiver module. Use the optical fiber to connect the Rx port and the Tx port on the transceiver module to the Tx port and the Rx port on the peer device, respectively.

To display transceiver module information:

Task	Command	Remarks
Display key parameters of transceiver modules.	display transceiver interface [ interface-type interface-number ]	Available for all transceiver modules.

Diagnosing transceiver modules

The device provides the alarm and digital diagnosis functions for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:

· Check the alarms on the transceiver module to identify the fault source.

· Examine the key parameters monitored by the digital diagnosis function, including the temperature, voltage, laser bias current, TX power, and RX power.

To diagnose a transceiver module:

For more information about transceiver module-rated commands, see the command references for the device.

Saving the running configuration

IMPORTANT:

You must save the running configuration to a .cfg configuration file.

You can use one of the following methods to save the running configuration:

· Fast mode—Use the save command without the safely keyword. In this mode, the device directly overwrites the target next-startup configuration file. If a reboot or power failure occurs during this process, the next-startup configuration file is lost. You must specify a new startup configuration file after the device reboots.

· Safe mode—Use the save command with the safely keyword. Safe mode is slower than fast mode, but more secure. In safe mode, the system saves the configuration in a temporary file and starts overwriting the target next-startup configuration file after the save operation is complete. If a reboot or power failure occurs during the save operation, the next-startup configuration file is still retained. Use the safe mode if the power source is not reliable or you are remotely configuring the device.

To save the running configuration:

Task

Command

Remarks

Save the running configuration to a configuration file, without specifying the file as a next-startup configuration file.

save file-url [ all | slot slot-number ]

Use either approach.

Available in user view.

Save the running configuration to a configuration file in the root directory of the storage medium, and specify the file as a next-startup configuration file.

save [ safely ]

Rebooting the device or a module

CAUTION:

· If the main system software image file does not exist, do not use the reboot command to reboot the device. Specify the main system software image file first, and then reboot the device.

· The precision of the rebooting timer is 1 minute. 1 minute before the rebooting time, the device prompts "REBOOT IN ONE MINUTE" and reboots in one minute.

· If you are performing file operations when the device is to be rebooted, the system does not execute the reboot command for security.

To reboot the device or a module, use one of the following methods:

· Reboot the device at the CLI.

¡ Reboot the device immediately by using the reboot command.

¡ Schedule a reboot to occur at a specific time or date or after a delay by using the schedule reboot command.

· Power off and then power on the device. This method cuts off the power of the device forcibly, which might cause data loss and hardware damage. It is the least-preferred method.

To reboot a module or the device immediately:

12 Managing RAID

Redundant Array of Independent Disks (RAID) is a technology that combines multiple independent drives into a single logical drive for data redundancy and performance improvement.

RAID levels

RAID is available in different levels. The device supports RAID levels 0 and 1.

RAID 0 is a data striping technology, which stripes data evenly across all drives. Theoretically, a RAID 0 array of N identical drives has N times the read/write performance and storage capacity of a single drive. RAID 0 has the advantages of low cost, high read-write performance and high storage space utilization, but it does not provide data redundancy. Once the data is damaged, it will not be recovered.

RAID 1, also known as drive mirroring, generates an ISO image file on another drive while data is being written to one drive. If the current drive fails, the system will read and write data from the drive with the image file. RAID 1 ensures data reliability and reparability. However, the maximum usable drive space of RAID 1 is only half of the total drive space.

Restrictions and guidelines for using RAID

RAID is a technology that combines multiple independent drives into a single logical drive. Two or more independent drives are required to create a RAID array. To create or rebuild a RAID array, make sure each member drive has only one partition and uses the EXT4 file system format.

Table12-1 RAID level and number of member drives

RAID level	Minimum number of drives	Maximum number of faulty drives
RAID 0	2	0
RAID 1	2	1

As shown in Figure12-3, the device has two SATA drive slots. You can install H3C SATA drives in the slots and configure RAID.

Before configuring RAID, make sure the device has been installed with a riser card and a storage controller.

Figure12-3 Front panel of the device

(0) SATA drive slot 0 (the drive in the slot is named hda)

(1) SATA drive slot 1 (the drive in the slot is named hdb )

Creating a RAID array

Before a RAID array is created, the member drives are independent of each other and you can only read from and write to the drives separately.

After a RAID array is created, all member drives will be used as a whole. Reading and writing data to one of the member drives is equivalent to reading and writing data to all member drives. After the RAID array is created, the original data on the member drives will be erased.

Installing hardware

A RAID array setup requires a riser card, storage controller, and SATA drives. The device does not come with these hardware options. Prepare and install these hardware options.

For information about installing riser cards, storage controllers, and SATA drives, see "Installing a storage controller" and "Installing SATA drives."

Configuring drives

Restrictions and guidelines

Make sure the member drives for creating the RAID array each have only one partition with the EXT4 file system format. To view detailed information about a drive, partition a drive, and format a drive, execute the dir, fdisk, and format commands, respectively. For more information about the dir, fdisk, and format commands, see the file system management commands in H3C SR6602-I[IE] AI-Powered ICT Converged Gateways Fundamentals Command Reference.

Procedure

1. Execute the fdisk command in user view to divide each SATA drive into one partition.

<Sysname> fdisk hda: 1

<Sysname> fdisk hdb: 1

By default, each SATA drive has one partition.

2. Execute the dir command in user view to view the file system format of the partition on each drive.

<Sysname> dir hda0:/

Directory of hda0: (EXT4)

0 drw- - Dec 10 2020 17:04:03 VmImages

1 drw- - Sep 04 2020 11:03:21 etc

2 drw- - Sep 04 2020 10:53:15 lost+found

<Sysname> dir hdb0:/

Directory of hdb0: (EXT4)

...

Directory of xxx: (EXT4) indicates that the file system format is EXT4.

3. If the file system format of a partition is not EXT4, execute the format command in user view to format the file system to EXT4.

<Sysname> format hda0: ext4

<Sysname> format hdb0: ext4

4. Reboot the device.

# Execute the reboot command in user view to reboot the device.

<Sysname> reboot

Rebuilding the RAID array

· A RAID 0 array cannot be rebuilt. When a member drive of a RAID 0 array is damaged, the RAID group is also damaged, and the data in the RAID group is damaged and cannot be recovered. To continue to use a RAID 0 array, you must delete the damaged RAID 0 array first, and then create a new RAID 0 array. For the method of deleting and creating a RAID 0 array, see "Creating a RAID array" and "Deleting a RAID array," respectively.

· A RAID 1 array can be rebuilt automatically. After you replace a damaged member drive, the RAID 1 array will automatically recognize the new drive and add it to the RAID group to replace the damaged member drive in the RAID group. After the RAID is rebuilt, the original data in the newly added member drive will be erased.
