Upgrading software
Overview
Software upgrade enables you to add new features and fix bugs. This chapter describes types of software and procedures to upgrade software from the CLI without using ISSU. For a comparison of all software upgrade methods, see "Upgrade methods."
When you upgrade software, you do not need to upgrade MPUs and interface cards separately. The software images are integrated for MPUs and interface cards. The interface cards upgrade automatically when you upgrade MPUs.
In an IRF 3 system, the parent devices and PEXs use separate software images. You must specify software images for the parent devices and PEXs separately. For more information about IRF 3, see Virtual Technologies Configuration Guide.
Unless otherwise stated, the term "IRF system" refers to both IRF fabrics and IRF 3 systems. The term "IRF fabric" refers to both a standalone IRF fabric and the parent fabric in an IRF 3 system.
|
NOTE: In an IRF 3 system, the master device on the parent fabric is also the master of the entire system. |
Software types
The following software types are available:
· BootWare image—A .bin file that contains a basic segment and an extended segment. The basic segment is the minimum code that bootstraps the system. The extended segment enables hardware initialization and provides system management menus. You can use these menus to load software and the startup configuration file or manage files when the device cannot start up correctly. For easy software compatibility management, the BootWare image is contained in the Boot image file. The BootWare image is upgraded automatically when the Boot image is upgraded.
· Comware image—Includes the following image subcategories:
¡ Boot image—A .bin file that contains the Linux operating system kernel. It provides process management, memory management, and file system management.
¡ System image—A .bin file that contains the minimum feature modules required for device operation and some basic features, including device management, interface management, configuration management, and routing. To have advanced features, you must purchase feature images.
¡ Feature image—A .bin file that contains advanced software features. Users purchase feature images as needed.
¡ Patch image—A .bin file irregularly released for fixing bugs without rebooting the device. A patch image does not add new features or functions.
Comware images that have been loaded are called current Comware images. Comware images specified to load at the next startup are called startup Comware images.
BootWare image, boot image, and system image are required for the system to operate. These images might be released separately or as a whole in one .ipe package file. If an .ipe file is used, the system decompresses the file automatically, loads the .bin images, and sets them as startup software images.
|
NOTE: BootWare might be called Boot ROM on PEXs. Unless otherwise stated, the term "BootWare" refers to both BootWare and Boot ROM in this document. |
Software file naming conventions
Software image file names use the chassis-comware version-image type-release format, for example, S7500E-CMW710-SYSTEM-R7178.bin and S7500E-CMW710-BOOT-R7178.bin.
Comware image redundancy and loading procedure
You can specify one main and one backup list of Comware software images.
The system always attempts to start up with the main images. If any main images do not exist or are invalid, the system tries the backup images. Figure 1 shows the entire Comware image loading procedure.
In this procedure, both the main and backup image lists have feature and patch images. If an image list does not have feature or patch images, the system starts up with the main boot and system images after they pass verification.
If both the main and backup boot images do not exist or are invalid, access the BootWare menu during the system startup to upgrade software.
Figure 1 Comware image loading procedure
System startup process
Upon power-on, the BootWare image runs to initialize hardware, and then the startup software images run to start up the entire system, as shown in Figure 2.
Figure 2 System startup process
PEX startup process
PEX startup process differs depending on the availability of storage media on PEXs.
· If a PEX has a storage medium, it can start up from the local medium or from the medium on the parent device.
· If a PEX does not have a storage medium, it must start up from the storage medium on the master device.
The following switches can be PEXs in an IRF 3 system:
· S5120-28SC-HI.
· S5120-52SC-HI.
· S5130-EI.
· S5130-HI.
· S6300.
The S5130-EI, S5130-HI, and S6300 switches have storage media, but the S5120-28SC-HI and S5120-52SC-HI switches do not.
|
NOTE: The PEX startup images on the PEX's local medium are called local startup images. The PEX startup images on the parent devices are called remote startup images. |
Startup process for S6300 and S5130-EI PEXs
1. Upon power-on, the PEX runs the BootWare image to initialize hardware and display hardware parameters.
2. The PEX attempts to load software images from its local storage medium (see Figure 4):
a. The PEX searches the local storage medium for startup images:
- If all the images exist and are valid, the PEX moves to step b.
- If any images do not exist or are invalid, the PEX goes to step 3.
b. The system verifies the compatibility of the PEX startup software images with the running software images of the global active MPU:
- If all the images are compatible, the PEX starts up with the images in the local medium.
- If any incompatibility exists, the PEX goes to step 3.
3. The PEX attempts to load software images from the global active MPU (see Figure 5):
a. The PEX searches the default storage medium on the global active MPU for PEX startup images:
- If all the images exist and are valid, the PEX moves to step b.
- If any images do not exist or are invalid, the startup process fails. You must specify new PEX startup images from the CLI or from the PEX's BootWare menus.
b. The PEX verifies the compatibility of the PEX startup software images with the running software images on the global active MPU:
- If the images are compatible, the PEX loads the PEX software images from the global active MPU.
- If any incompatibility exists, the startup process fails. You must specify new PEX startup images from the CLI or from the PEX's BootWare menus.

Figure 5 S6300/S5120-HI PEX startup from the parent device's storage medium
Startup process for S5120-HI PEXs
1. Upon power-on, the PEX runs the BootWare image to initialize hardware and display hardware parameters.
2. The PEX attempts to load software images from the master device (see Figure 6):
a. The PEX searches the default storage medium on the global active MPU for the startup images:
- If all the images exist and are valid, the PEX goes to step b.
- If any images do not exist or are invalid, the startup process fails. You must specify new PEX startup images from the CLI.
b. The PEX verifies the compatibility of the PEX startup software images with the running software images on the global active MPU (see Figure 5):
- If the images are compatible, the PEX loads the PEX software images from the global active MPU.
- If any incompatibility exists, the startup process fails. You must specify new PEX startup images from the CLI or from the PEX's BootWare menus.

Upgrade methods
Upgrading method |
Software types |
Remarks |
Upgrading from the CLI without using ISSU |
· BootWare image · Comware images (excluding patches) |
This method is disruptive. You must reboot the entire device to complete the upgrade. |
Performing an ISSU |
Comware images |
The ISSU method enables a software upgrade without service interruption. Use this method for an IRF fabric. For more information about ISSU, see "Performing ISSU." |
Upgrading from the BootWare menu |
· BootWare image · Comware software images |
Use this method when the device cannot start up correctly. To use this method, first connect to the console port and power cycle the switch or PEX. Then press Ctrl+B at prompt to access the BootWare menu. For more information about upgrading software from the BootWare menu, see the release notes for the software version.
Upgrade an IRF system from the CLI rather than the BootWare menu, if possible. The BootWare menu method increases the service downtime, because it requires that you upgrade the member devices one by one. |
This chapter only covers upgrading software from the CLI without using ISSU.
Upgrade restrictions and guidelines
The switch starts up from the default storage medium. The default storage medium can be the built-in flash memory or a USB disk. To change the default storage medium setting, access the BootWare menu. For more information, see the release notes for the switch.
H3C recommends that you store the startup images in the flash memory and specify the flash memory as the default storage medium.
If the switch is starting up from a USB disk, do not remove the USB disk during startup.
Preparing for the upgrade
1. Use the display version command to verify the current BootWare image version and startup software version.
2. Use the release notes for the upgrade software version to evaluate the upgrade impact on your network and verify the following items:
¡ Software and hardware compatibility.
¡ Version and size of the upgrade software.
¡ Compatibility of the upgrade software version with the current BootWare image and startup software image version.
¡ Licensing requirements for the upgrade software images. If licenses are required, register and activate licenses for each license-based software image. For more information about licensing, see "Managing licenses."
3. Use the dir command to verify that all MPUs have sufficient storage space in the default storage medium for the upgrade images. If the storage space is not sufficient, delete unused files by using the delete command. For more information, see "Managing the file system."
4. Use FTP or TFTP to transfer the upgrade image file to the root directory of the default storage medium on the active MPU (in standalone mode) or the global active MPU (in IRF mode).
For more information about FTP and TFTP, see "Configuring FTP" and "Configuring TFTP."
Upgrade task list
Tasks at a glance |
Remarks |
(Optional.) Preloading the BootWare image to BootWare |
If a BootWare upgrade is required, you can perform this task to shorten the subsequent upgrade time. This task helps avoid upgrade problems caused by unexpected electricity failure. If you skip this task, the device upgrades the BootWare automatically when it upgrades the startup software images. The BootWare image preloaded into the BootWare take effect only after you reboot the device. You can perform this task to upgrade the BootWare image for the device or a PEX. |
(Required.) Specifying startup images and completing the upgrade |
Perform this task to upgrade a standalone device, an IRF fabric, or the parent fabric in an IRF 3 system. Start with the parent fabric when you upgrade the parent fabric and PEXs in an IRF 3 system. |
(Optional.) Upgrading PEXs |
Perform this task to upgrade the PEXs in an IRF 3 system. |
(Optional.) Restoring or downgrading the BootWare image without using ISSU |
N/A |
(Optional.) Enabling software synchronization from the active MPU to the standby MPU at startup |
By default, software synchronization is enabled. This feature enables automatic software synchronization when the device operates in standalone mode. With software synchronization, you do not need to manually upgrade the standby MPU. To synchronize software from the global active MPU to other MPUs on an IRF fabric, use the irf auto-update enable command. |
Preloading the BootWare image to BootWare
BootWare is called bootrom in CLI.
To preload the BootWare image to BootWare:

At startup, the system runs the new BootWare image to complete the restoration or downgrade. |
Enabling software synchronization from the active MPU to the standby MPU at startup
This feature is available only when the device operates in standalone mode. To synchronize software from the global active MPU to other MPUs on an IRF fabric, use the irf auto-update enable command. For more information about software auto-update, see Virtual Technologies Configuration Guide.
When the standby MPU starts up, this feature examines its startup software images for version inconsistency with the current software images on the active MPU.
If the software versions are different, the standby MPU does the following:
1. Copies the current software images of the active MPU.
2. Specifies the images as startup software images.
3. Reboots with these images.
|
IMPORTANT: To ensure a successful synchronization in a multiuser environment, prevent users from rebooting or swapping MPUs during the software synchronization process. You can configure the information center to output the synchronization status to configuration terminals (see Network Management and Monitoring Configuration Guide). |
