9.2.3.4 ahfctl deleteupdatebackup

Use the ahfctl deleteupdatebackup command to delete the backup directories used for AHF update.

Note:

• To delete the backup directories on all nodes in a cluster, you must run the ahfctl deleteupdatebackup command as the AHF install user on each cluster node.
• You must not delete the backup directories randomly. Oracle recommends deleting the backup directories in the same order the updates were applied. If you delete the backup directories associated with a specific timestamp, then you will not be able to roll back to the state before the updates with that specific timestamp were applied.
• Upgrading AHF using the ahf_setup script automatically deletes the backup directories of the previous AHF versions.
• Oracle recommended to delete the AHF update backup directories only when there's a need to free up space on the system. You cannot delete the AHF update backup directory of the current running timestamp/update because once the backup directory is deleted for the specific timestamp, rolling back the update to specific timestamp/update is not possible.

  For example: AHF Updates applied in order is: 20230901 -> 20231001 -> 20231101 (Current latest update). You can delete update backups for 20230901 and 20231001 but not the 20231101.
