Rolling back the running software images
For each service or file upgrade performed through activate or deactivate operation, the system creates a rollback point. The rollback points are retained until any of the following event occurs:
An ISSU reboot or reboot upgrade is performed.
The install commit command is executed.
After an ISSU reboot or reboot upgrade is performed, you can roll back the running software images only to the status before any activate or deactivate operations are performed.
After a commit operation is performed, you cannot perform a rollback.
For a rollback to take effect after a reboot, you must perform a commit operation to update the main startup software image list.
To roll back the software, execute the following commands in user view:
Step | Command | Remarks |
---|---|---|
1. (Optional.) Display available rollback points. | display install rollback | A maximum of 50 rollback points are available for service and file upgrades. The earliest rollback point is removed if this limit has been reached when a rollback point is created. |
2. Roll back the software. | install rollback to { point-id | original } | N/A |
