Rolling Back The Software Configuration - HP 12500 Configuration Manual

Uninstalled images are still saved on the storage medium. To permanently remove the images from the
device, execute the install remove command. Make sure you remove only images that are no longer
useful.
To uninstall an image that was installed for an incremental upgrade, deactivate it and then confirm the
software change. If you do not confirm the deactivation, the deactivated image will become active after
a reboot. To uninstall an image that was installed for a reboot upgrade or ISSU reboot upgrade, you only
need to deactivate it.
To uninstall feature images, execute the following commands in user view:
Step
1. Deactivate feature images.
2. (Optional.) Confirm the software
changes.
To uninstall patch images, execute the following commands in user view:
Step
1. Deactivate patch images.
2. (Optional.) Confirm the software
changes.

Rolling back the software configuration

Every time you activate or deactivate a software image for an incremental upgrade or downgrade, the
system creates a rollback point to record the current software configuration. Before you execute the install
commit command to confirm the software changes (executing this command also removes all rollback
points), you can roll back the software configuration to a rollback point to cancel all software image
upgrade-related operations performed after the rollback point. You can also roll back the software
configuration to the original software configuration, the software configuration before you perform an
ISSU.
For an incremental upgrade, up to 50 rollback points are supported. After the limit is reached, the oldest
rollback point is deleted to make room for a newly created one.
For ISSU reboot upgrades and reboot upgrades, the system does not record and maintain any rollback
point, and you can roll back the software configuration only to the original software configuration.
To make a rollback for an incremental upgrade take effect after a reboot, you must confirm the rollback
operation using the install commit command. A rollback for a reboot upgrade or an ISSU reboot
upgrade does not need to be confirmed by using the install commit command.
To roll back the software configuration, execute the following commands in user view:
