Software upgrade commands

MDC is supported only when the device operates in standalone mode. For more information about standalone mode, see IRF configuration in Virtual Technologies Configuration Guide. For more information about MDC and device models that support MDC, see MDC configuration in Virtual Technologies Configuration Guide.

 

IMPORTANT: As a best practice, store the startup images in a fixed storage medium. If you store the startup images in a hot swappable storage medium, do not remove the hot swappable storage medium during the startup process.

 

boot-loader file

Use boot-loader file to specify startup image files.

Syntax

In standalone mode:

boot-loader file boot filename system filename [ feature filename&<1-30> ] [ patch filename&<1-16> ] { all | slot slot-number } { backup | main }

boot-loader file ipe-filename [ patch filename&<1-16> ] { all | slot slot-number } { backup | main }

In IRF mode:

boot-loader file boot filename system filename [ feature filename&<1-30> ] [ patch filename&<1-16> ] { all | chassis chassis-number slot slot-number } { backup | main }

boot-loader file ipe-filename [ patch filename&<1-16> ] { all | chassis chassis-number slot slot-number } { backup | main }

Parameters

boot: Specifies a boot image file.

system: Specifies a system image file.

feature: Specifies a space-separated list of up to 30 feature image files.

patch: Specifies a space-separated list of up to 16 patch image files. You can specify only non-incremental patch image files.

filename: Specifies a .bin file in the filesystemname/filename.bin format. The file must be stored in the root directory of a file system on the device. Excluding the file system location section (if any), the value string can have a maximum of 63 characters. For more information about specifying a file, see Fundamentals Configuration Guide.

ipe-filename: Specifies an .ipe image package file in the filesystemname/filename.ipe format. The file must be stored in the root directory of a file system on the device. Excluding the file system location section (if any), the value string can have a maximum of 63 characters. For more information about specifying a file, see Fundamentals Configuration Guide.

all: Specifies all hardware components to which the specified images apply.

slot slot-number: Specifies the slot number of an MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies an MPU in the IRF fabric. The chassis-number argument represents the IRF member ID of the device that holds the MPU. The slot-number argument represents the slot number of the MPU. (In IRF mode.)

backup: Specifies the files as backup startup image files. Backup images are used only when main images are not available.

main: Specifies the files as main startup image files. The device always first attempts to start up with main startup files.

Usage guidelines

Application scenarios

When the current software cannot meet the requirements of network operation or user services, you can use this command to upgrade the software to optimize device performance to meet the requirements.

Operating mechanism

The boot-loader file command overwrites the entire startup image list. To add new startup feature images, specify all feature image files in the old startup image list, including feature image files. The new startup image list will contain only the feature image files that are specified in the command.

If the upgrade images are not found in the file system on the slot specified to upgrade, the system automatically copies the images to that file system. The destination directory is the root directory of the file system. If the destination root directory already contains a startup image with the same name as an upgrade image, you must choose whether to overwrite the image.

Restrictions and guidelines

The system will verify the digital signature of the specified images before it updates the startup image list with the specified images. If the digital signature verification fails, the system will not update the startup image list and you will receive a digital signature verification failure message.

To load the specified startup software images, you must reboot the system.

Examples

# (In standalone mode.) Specify flash:/all.ipe as the main startup image file.

<Sysname> boot-loader file flash:/all.ipe all main

Verifying the file flash:/all.ipe on slot 1..............Done.

boot-loader update

Use boot-loader update to synchronize startup images.

Syntax

In standalone mode:

boot-loader update { all | slot slot-number }

In IRF mode:

boot-loader update { all | chassis chassis-number slot slot-number }

Parameters

all: Synchronizes startup images from the active MPU to the standby MPU. (In standalone mode.)

all: Synchronizes startup images from the global active MPU to all standby MPUs. (In IRF mode.)

slot slot-number: Specifies the slot number of the standby MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a standby MPU. The chassis-number argument represents the IRF member ID of the device that holds the MPU. The slot-number argument represents the slot number of the MPU. (In IRF mode.)

Usage guidelines

Prerequisites

If any of the startup software images require a license, register and activate a license for the image on the new MPU before executing this command. Use the display license feature command to verify the licensing state of software images.

Application scenarios

You can use this command to synchronize startup images after adding new MPUs.

Operating mechanism

The images used for synchronization are in the main or backup startup software images list instead of the current software images list (see the display boot-loader command).

·     The main images list is used if the active MPU (in standalone mode) or global active MPU (in IRF mode) started up with the main startup images.

·     The backup image list is used if the active MPU (in standalone mode) or global active MPU (in IRF mode) started up with the backup startup images.

The startup images synchronized to a standby MPU are set as main startup images, regardless of whether the source startup images are main or backup.

Restrictions and guidelines

If a patch installation or ISSU has been performed, use the install commit command to update the main startup images on the active MPU (in standalone mode) or global active MPU (in IRF mode) before software synchronization. This command ensures startup image consistency between the active MPU or (in standalone mode) or global active MPU (in IRF mode) and standby MPUs.

Startup image synchronization fails if any software image being synchronized is not available or is corrupted.

Examples

# Synchronize startup images to a slot.

<Sysname> boot-loader update slot 2

This command will update the specified standby MPU. Continue? [Y/N]:y

Parameters

file file: Specifies the file that contains the BootWare image. The file argument represents the file name, a string of 1 to 63 characters.

slot slot-number-list: Specifies a space-separated list of up to seven slot number items. An item specifies a card by its slot number or a range of cards in the form of start-slot-number to end-slot-number. The end slot number must be equal to or greater than the start slot number. (In standalone mode.)

chassis chassis-number: Specifies an IRF member device by its member ID. (In IRF mode.)

slot slot-number-list: Specifies a space-separated list of up to seven slot number items. An item specifies a card by its slot number or a range of cards in the form of start-slot-number to end-slot-number on the specified IRF member device. The end slot number must be equal to or greater than the start slot number. (In IRF mode.)

Usage guidelines

Application scenarios

BootWare images are contained in the .bin Comware boot image file. You can specify a Comware boot image file in this command to upgrade the BootWares in the system before you upgrade the Comware images. If you do not upgrade BootWares before upgrading Comware images, the system automatically upgrades BootWares as necessary when loading Comware images.

Operating mechanism

After you use this command, the system loads the specified BootWare image in the file system to the Normal area of BootWare. The system directly uses the BootWare image in the Normal area when it starts up. If the storage space is insufficient, you can delete the BootWare image file after the system has loaded the BootWare image.

Restrictions and guidelines

The system will verify the digital signature of a BootWare image before it loads that image to the Normal area of BootWare. If the digital signature verification fails, the system will not load that image and you will receive a digital signature verification failure message.

The new BootWare images take effect after you reboot the card.

Examples

# (In standalone mode.) Use the file a.bin in the root directory of the flash memory to upgrade the BootWare image.

<Sysname> bootrom update file flash:/a.bin slot 1

   This command will update the Boot ROM file on the specified board(s), Continue? [Y/N]:y

   Now updating the Boot ROM, please wait................Done.

version auto-update enable

Use version auto-update enable to enable software synchronization from active MPU to standby MPU at startup.

Use undo version auto-update enable to disable this feature.

Syntax

version auto-update enable

undo version auto-update enable

Default

Software synchronization from active MPU to standby MPU is enabled. If software inconsistency is detected at startup, the standby MPU loads the current software images of the active MPU.

Predefined user roles

network-admin

Usage guidelines

Operating mechanism

To make sure the standby MPU always runs the same software images as the active MPU, configure both the version auto-update enable command and the undo version check ignore command.

The startup software version check feature examines the standby MPU's startup software images for version inconsistency with the active MPU's current software images at startup. If their software versions are different, the standby MPU copies the current software images of the active MPU, specifies them as main startup software images, and reboots with these images.

Restrictions and guidelines

Use the undo version auto-update enable and version check ignore commands with caution. Configured with these two commands, the system will not examine the standby MPU's startup software images for version inconsistency with the active MPU's current software images. The standby MPU can start up with a different software version than the active MPU. This might cause the device to malfunction.

This command is available in standalone mode.

To ensure a successful synchronization in a multiuser environment, make sure no one reboots or swaps 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).

Examples

# Enable software auto-update for the standby MPU.

<Sysname> system-view

[Sysname] version auto-update enable

Related commands

version check ignore

version check ignore

Use version check ignore to disable startup software version check for the standby MPU at startup.

Use undo version check ignore to enable this feature.

Syntax

version check ignore

Usage guidelines

Operating mechanism

When the standby MPU starts up, this command disables the system to examine the standby MPU's startup software images for version inconsistency with the active MPU's current software images. The standby MPU can start up with a different software version than the active MPU.

If you enable startup software version check for the standby MPU, the system will prevent the standby MPU from starting up with a different software version than the active MPU.

Restrictions and guidelines

To avoid anomalies, do not disable startup software version check for the standby MPU unless for software upgrade. The device might malfunction if the standby MPU starts up with a different software version than the active MPU.

This command is available in standalone mode.

To make sure the standby MPU always runs the same software images as the active MPU, use both the version auto-update enable command and the undo version check ignore command.

Examples

# Enable startup software version check for the standby MPU.
