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

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

boot-loader file ipe-filename [ patch filename&<1-30> ] { all | 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 30 incremental patch image files or 16 non-incremental patch image files. Because the boot, system, and feature images each can have one non-incremental patch image file, you can specify a maximum of 16 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: Upgrades the entire system.

slot slot-number: Specifies the slot number of an MPU.

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

Prerequisites

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

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

Views

User view

Predefined user roles

network-admin

Parameters

all: Synchronizes startup images from the active MPU to the standby MPU.

slot slot-number: Specifies the slot number of the standby MPU.

Usage guidelines

Prerequisites

Application scenarios

You can use the boot-loader update 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 started up with the main startup images.

· The backup image list is used if the active MPU 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 has been performed, use the install commit command to update the main startup images on the active MPU before software synchronization. This command ensures startup image consistency between the active MPU and the standby MPU.

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 0

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

Syntax

bootrom backup slot slot-number-list [ all | part ]

Views

User view

Predefined user roles

network-admin

Parameters

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.

all: Backs up the entire BootWare image, including the basic segment and the extended segment. If you do not specify the all or part keyword, this command backs up the entire BootWare image.

part: Backs up the extended BootWare image section.

Usage guidelines

A BootWare is divided into a Normal area and a Backup area. The BootWare image is stored in the Normal area and backed up to the Backup area. At startup, the system reads the BootWare image automatically from the Normal area. If the image is inaccessible, the system reads the BootWare image from the Backup area.

If the BootWare image in the Normal area is corrupted or requires a version rollback, use the bootrom restore command to copy the BootWare image in the Backup area to the Normal area.

Examples

# Back up the entire BootWare image from the Normal area to the Backup area.

<Sysname> bootrom backup slot 1

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.

all: Loads the entire BootWare image, including the basic segment and the extended segment. If you do not specify the all or part keyword, this command restores the entire BootWare image.

part: Loads the extended BootWare image section.

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 new BootWare images take effect after you reboot the card.

Examples

# 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

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

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.

Views

System view

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.

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).

Predefined user roles

network-admin

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.

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.

For more information about specifying a file, see file system management in Fundamentals Configuration Guide.

all: Specifies all cards on the device.

slot slot-number: Specifies a card by its slot number.

Usage guidelines

Images run in memory immediately after they are activated. However, only images activated by using the install activate patch filename all command still run in memory after a reboot. For other images to take effect after a reboot, you must commit the software changes by using the install commit command.

If the specified files are not stored on the MPU to be upgraded, the command copies the files to the MPU automatically.

If you specify the active MPU for the slot slot-number option, the command takes effect on the active MPU and all service modules. If you specify the standby MPU for the slot slot-number option, the command takes effect only on the standby MPU.

You can install up to 32 .bin files on the device, including one boot image file, one system image file, and up to 30 feature or patch image files.

Examples

# Activate the feature images in feature1.bin on the standby MPU (in slot 1).

Parameters

bypass-signature-verify: Skips digital signature verification on startup software images.

Usage guidelines

Application scenarios

You must execute this command after using the following commands:

· The install activate command in an incremental upgrade.

· The install deactivate command.

· The install rollback command.

Operating mechanism

This command adds patches to the startup software image list that the device is using.

· If the device is using the main startup software image list, this command adds patches to the main startup software image list.

· If the device is using the backup startup software image list, this command adds patches to the backup startup software image list.

Both the install commit and boot-loader file commands modify the main startup software image list. To modify the backup startup image list or add inactive images as main startup images, however, you must use the boot-loader file command.

Restrictions and guidelines

In a reboot or ISSU reboot upgrade, the install activate command modifies the software image list used for next startup. You do not need to commit software changes.

The bypass-signature-verify keyword speeds up execution of the install commit command by skipping digital signature verification on startup software images.

Examples

# Commit software changes.

<Sysname> install commit
