install abort
Use install abort to abort an ongoing activate or deactivate operation.
Syntax
install abort [ job-id ]
Views
User view
Predefined user roles
network-admin
Parameters
job-id: Specifies the job ID of an ISSU operation. If you do not specify this argument, the command aborts all ongoing software image activate and deactivate operations.
Usage guidelines
Operating mechanism
When you abort an ongoing activate or deactivate operation, the system rolls back to the status it was in before the operation was started.
Restrictions and guidelines
The system creates a software image management job each time you use the install activate, install add, install commit, install deactivate, install remove, or install rollback to command. Each job represents one command and is assigned a unique job ID. To obtain the ID of a job, use the display install job command.
Examples
# Abort all ongoing software image activate and deactivate operations.
<Sysname> install abort
Related commands
display install job
install activate
Use install activate to activate software images, or identify the ISSU method and the possible impact on the device.
Syntax
install activate { boot filename | system filename | feature filename&<1-30> } * slot slot-number [ test ]
install activate patch filename { all | slot slot-number }
Views
User view
Predefined user roles
network-admin
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 patch image file. You can specify only one patch image file for the command at a time. However, you can execute the command multiple times to activate multiple patch image files. You can specify both incremental and non-incremental patch image files. The device can use a maximum of 30 incremental patch image files. Because the boot, system, and feature images each can have one non-incremental patch image file, the device can use a maximum of 16 non-incremental patch image files. For more information about incremental and non-incremental patch images, see software upgrade in Fundamentals Configuration Guide.
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. The value string excluding the file system location section (if any) can have a maximum of 63 characters. For more information about specifying a file, see file system management in Fundamentals Configuration Guide.
all: Specifies all cards.
slot slot-number: Specifies a card by its slot number.
test: Only identifies the ISSU method to be used for the upgrade. If you do not specify this keyword, the command activates the specified software images.
Prerequisites
Before you use this command to activate a software image, read the release notes to identify the licensing requirements for the image. If the image requires a license, make sure the device has a valid license installed for the image.
Restrictions and guidelines
The software images for the device are digitally signed. The system verifies the digital signature of a software image for authenticity and integrity before it activates it. If the digital signature verification fails, the system will not activate the image and you will receive a digital signature verification failure message.
This command requires that all image files on the startup software image list be the same version after the upgrade is finished. It can be executed successfully only if the boot, system, and feature image files on the list are the same version after the upgrade. Before being executed successfully, this command uninstalls all existing patch image files on the list automatically.
If this command fails, perform the following tasks:
1. If some features are not needed anymore, disable the features and use the install deactivate command to uninstall the feature images.
2. Obtain the image files that are required to make sure all image files on the startup software image list are the same version after the upgrade.
3. Specify the image files for this command to activate the images.
Images run in memory immediately after they are activated. However, only patch 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 change 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 LPUs. If you specify the standby MPU for the slot slot-number option, the command takes effect only on the standby MPU.

Parameters
ipe-filename: Specifies an .ipe file in the filesystemname/filename.ipe format. The file must be stored in the root directory of a file system on the device. The value string excluding the file system location section (if any) can have a maximum of 63 characters. For more information about specifying a file, see file system management in Fundamentals Configuration Guide.
filesystem: Specifies the destination file system for the software images, in the filesystemname format.
Usage guidelines
To use the install activate command to activate software images, you must use .bin image files. If the upgrade file is an .ipe file, use this command to decompress the .ipe file before you start the upgrade.
To identify software images that are included in an .ipe file, use the display install ipe-info command.
Examples
# Decompress all.ipe to the flash memory.
<Sysname> install add flash:/all.ipe flash:

Usage guidelines
Prerequisites
Before you use this command, read the release notes to identify software image licensing requirements. Make sure the device has valid licenses for all license-based images.
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 the patch image file to the startup software image list that the device used at startup.
· If the device used the main startup software image list at startup, this command adds the patch image file to the main startup software image list.
· If the device used the backup startup software image list at startup, this command adds the patch image file 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.
For more information about main and backup startup software images, see Fundamentals Configuration Guide.
Restrictions and guidelines
In a reboot upgrade, the install activate command modifies both the current and startup software image lists. You do not need to commit software changes.
Examples
# Commit software changes.
<Sysname> install commit
This operation will take several minutes, please wait...........................Done.
The current software images have been saved as the startup software images.
Current software images on slot 1:
flash:/boot.bin
flash:/system.bin
Current software images on slot 2:
flash:/boot.bin

Parameters
feature: Specifies a space-separated list of up to 30 feature image files.
patch: Specifies a patch image file. You can specify only one patch image file for the command at a time. However, you can execute the command multiple times to deactivate multiple patch image files.
filename: Specifies a .bin file in the filesystemname/filename.bin format. The value string can have a maximum of 63 characters. The file system name cannot contain file system location information. For more information about specifying a file, see file system management in Fundamentals Configuration Guide.
all: Specifies all cards on which the specified patch image file has been activated.
slot slot-number: Specifies a card by its slot number.
Usage guidelines
Prerequisites
Restrictions and guidelines
You can deactivate only active feature and patch images.
Images stop running in memory immediately after they are deactivated. However, only patch images deactivated by using the install deactivate patch filename all command do not run after a reboot. To prevent other deactivated images from running after a reboot, you must commit the software change by using the install commit command.
Examples
# Deactivate the patch images in the route-patch.bin file for a slot.
<Sysname> install deactivate patch flash:/route-patch.bin slot 1

Usage guidelines
This command permanently deletes the image files from the device. You cannot use the install rollback to command to revert the operation, or use the install abort command to abort the operation.
Examples
# Delete inactive software image file flash:/feature1.bin.
<Sysname> install remove flash:/feature1.bin
install rollback to
Use install rollback to to roll back the software to an earlier rollback point.
Syntax
install rollback to original

Predefined user roles
network-admin
Parameters
original: Rolls back to the status before any activate or deactivate operations were performed.
Application scenarios
During an incremental upgrade, the system creates a rollback point for each activate or deactivate operation of a boot, system, or feature image. The device supports a maximum of 50 rollback points. The earliest rollback point is deleted if this limit has been reached when a rollback point is created.
Restrictions and guidelines
During a reboot upgrade, the system does not create rollback points. After the upgrade, you can roll back the software only to the status before any activate or deactivate operations were performed.
For a rollback to take effect after a reboot, you must perform a commit operation to update the main startup software image list.
After a commit operation is performed, you cannot perform a rollback.
Patch images do not support rollback.
Examples
# Roll back the software to the original software versions and observe the change made by the rollback.
<Sysname> display install active
Active packages on slot 1:

reboot: Uses the reboot method for the upgrade. For an incremental upgrade or container upgrade, specify this keyword if you want to use the reboot upgrade method. If you do not specify this keyword, the recommended upgrade method is used.
Usage guidelines
Prerequisites
Operating mechanism
This command performs the following operations:
· Checks the version compatibility.
· Identifies the upgrade method.
· Loads the new images to upgrade the specified MPU.
· Sets the new images as the main startup software images for the specified MPU so the upgrade can survive a reboot.
Restrictions and guidelines
The software images for the device are digitally signed. The system verifies the digital signatures of the specified software images for authenticity and integrity before it sets or loads them as main startup images. If the digital signature verification fails, the system will not set or load the specified images as main startup images and you will receive a digital signature verification failure message.
This command requires that all image files on the startup software image list be the same version after the upgrade is finished. It can be executed successfully only if the boot, system, and feature image files on the list are the same version after the upgrade. Before being executed successfully, this command uninstalls all existing patch image files on the list automatically.
If this command fails, perform the following tasks:
1. If some features are not needed anymore, disable the features and use the install deactivate command to uninstall the feature images.
2. Obtain the image files that are required to make sure all image files on the startup software image list are the same version after the upgrade.
3. Specify the image files for this command to activate the images.
Examples
# On a dual-MPU device, upgrade the standby MPU with feature image file flash:/feature1.bin, and install a patch image file for the feature image. (In this example, the image is compatible with the running images.)

Usage guidelines
Prerequisites
Restrictions and guidelines
This command starts and finishes an ISSU. During the operation, you cannot perform a rollback or any other tasks.
Both the current software version and the new software version must support one-step ISSU.
This command requires that all image files on the startup software image list be the same version after the upgrade is finished. It can be executed successfully only if the boot, system, and feature image files on the list are the same version after the upgrade. Before being executed successfully, this command uninstalls all existing patch image files on the list automatically.
If this command fails, perform the following tasks:
1. If some features are not needed anymore, disable the features and use the install deactivate command to uninstall the feature images.
2. Obtain the image files that are required to make sure all image files on the startup software image list are the same version after the upgrade.
3. Specify the image files for this command to activate the images.

issu rollback
Use issu rollback to cancel the ISSU and roll back to the original software versions.
Syntax
issu rollback
Views
User view
Predefined user roles
network-admin
Application scenarios
The device supports automatic rollback and manual rollback. This command performs a manual rollback.
You can perform a manual rollback while an ISSU is in one of the following states:
· Loaded.
· Switching (during an upgrade to a compatible version).
· Switchover (during an upgrade to a compatible version).
· Accepted.
Restrictions and guidelines
In Switching state, a rollback during a reboot upgrade and an automatic rollback during an incompatible upgrade can result in the following situations:
· The standby MPU, which has been upgraded, reboots.
· The active MPU might also reboot because of an active/standby switchover, resulting in service outage.
· After the rollback, the MPUs run the software that they run before the upgrade, but their active/standby roles might not be the same as before.
As a best practice, make sure the automatic rollback timer is long enough, and do not perform a rollback while an ISSU is in Switching state.
Examples
# Roll back to the original software versions.
<Sysname> issu rollback
This command will quit the ISSU process and roll back to the previous version. Continue? [Y/N]:y

Parameters
minutes: Specifies the automatic rollback interval, in the range of 0 to 120 minutes. Setting it to 0 disables automatic rollback.
Usage guidelines
Application scenarios
The automatic software version rollback feature is only available for a dual-MPU device during an ISSU to a compatible version.
Restrictions and guidelines
The system starts the automatic rollback timer when you execute the issu run switchover command in a scenario where automatic rollback is supported. If you do not execute the issu accept or issu commit command before the timer expires, the system automatically rolls back to the software version used before the ISSU.
Change to the automatic rollback interval does not take effect on the ongoing ISSU process.
Examples
# Set the automatic rollback timer to 50 minutes.
<Sysname> system-view
[Sysname] issu rollback-timer 50
Related commands
issu rollback
issu run switchover

Usage guidelines
Operating mechanism
Use this command if the device has two MPUs.
· For a compatible upgrade, this command performs operations depending on the ISSU method.
¡ Incremental upgrade—Performs a process-level active/standby switchover for the processes to be upgraded.
¡ Reboot upgrade—Reboots the current active MPU with the old software version. The upgraded MPU then becomes the new active MPU.
· For an incompatible upgrade, this command reboots the current active MPU to use the new software version. The upgraded MPU then becomes the new active MPU. After the reboot, the original active MPU is upgraded, and the ISSU process ends.
Restrictions and guidelines
When you execute the issu run switchover command during an ISSU to a compatible version, the system starts the automatic rollback timer. If you do not execute the issu accept or issu commit command before the timer expires, the system automatically rolls back to the original software versions.
