Advanced topic: removing superseded patches from a depot

If you have a depot that you are using for patch installation that contains both superseded patches and corresponding superseding patches, the superseded patches will never be installed and are a waste of disk space. There is a patch utility called cleanup that you can use to remove all patches from a software depot if they have been superseded by patches that are also available in the depot. This command works only for directory depots, not tape depots.

The cleanup utility is delivered by the following patches (and their superseding patches):

•PHCO_27779 (HP-UX 11.0, B.11.00)

•PHCO_27780 (HP-UX 11i v1, B.11.11)

•PHCO_32220 (HP-UX 11i v2, B.11.23)

•Shipped with SD-UX (HP-UX 11i v3, B.11.31)

To execute cleanup on the depot some_depot, you can use the following command:

cleanup [-p]-d /some_directory/some_depot

If you use the -poption, the command executes in preview mode. You will be able to see what changes will be made without any changes actually occurring. HP recommends that you always execute the command in preview mode first.

For additional information and command options, see the cleanup(1M) manpage.

The following example shows how to use the cleanup command to remove superseded patches from the depot /my_depots/patch_depot.

•Use the swlist command to show the contents of depot /my_depots/patch_depot. The depot contains two patches: PHCO_24630 and PHCO_27780. The patch PHCO_27780 supersedes PHCO_24630.

$ swlist -l product -d @ /my_depots/patch_depot

#Initializing...

#Contacting target "my_system"...

#

#Target: my_system:/my_depots/patch_depot

PHCO_24630 1.0 HP-UX Patch Tools PHCO_27780 1.0 HP-UX Patch Tools

•Use the cleanup command in preview mode to see what changes will occur. The command output shows that patch PHCO_24630 will be removed because the cleanup command removes superseded patches; the output states “PHCO_24630 superseded by PHCO_27780”.

$ /usr/sbin/cleanup -p -d /my_depots/patch_depot
