Hi
I installed patch on 11.00 using swinstall.
But now i would like to remove that.How should i?

If you did not turn off the save the current software option in swinstall which is the default behavior then all you need to do is a swremove and the previous version will be restored.

Man swremove for details. You can use the interactive version of swremove if you like.

Hi Subhashini,

Start 'swremove', then select the patch you need to remove and remove it using the action menu.

Hi,

From the man pages :

"When removing installed software, swremove also unconfigures the software before it is removed. The software is not unconfigured when removed from an alternate root directory since it was not configured during installation. When removing available software (within a depot), swremove also does not perform the unconfiguration task". So for a normal swremove, you don't need to do anything more.

Did you remove the patch for more free space ? The default patch depot is in /var/adm/sw. So if u remove a patch from there, then how will it affect /usr ? Can you tell the patch name which you removed ?

However, if you want to check the free space, use 'du -k' command, instead of bdf.

Hi,

The patch you removed is the latest HP's patch bundle. You will have problem in future, if you remove these patches.

For getting free space on file system, you can work on other possibilities:

1) Add a new disk to the VG and extend the LV.
2) Remove unwanted log files or move it.
3) Find out for any new files in the file system ( man find)
4) Find the bigger files in the directory using find command.

Removing the patch bundle for freeing space is not a good idea.

Hi,

You should not remove patches to install newer patches. There is a concept of superceeding patches. Newer ones take precedent of older ones.

By default, swinstall saves copies of files that are overlaid by patches. This is so that you can roll-back to previous versions should you have to remove a patch later. These previous versions are stored in /var/adm/sw/save. Do not remove these files manually. Use the cleanup command. There is an option (-c perhaps, I'm not on an HPUX system right now) that allows you to specify how many times a patch is superceeded before committing the older patch and removing the previous files that patch overwrote. I suggest you specify 2 for that option.

Hi,

You don't need to remove an old patch bundle(s) to install new ones. What is generally done is to run the 'cleanup' command which removes the patch bundle before the last one superceded and redundant, and then when you install the newest bundle it makes the previous one as a fallback.

It is always a good ideas to keep the previous
bundle set, just in case.

As always I recommend that you make at least one make_tape_recovery tape before doing any patch changes, particularly ones related to kernels.

Hi Subhashini,

Like Darrell and Mike said, you don't need to remove the old patch bundle. The new releases completely overwrite the old bundles.Carefully read the README.txt document for instructions for installation.

Also the cleanup ( see man cleanup) command can be used to remove old patches from the system. It is NOT recommended to remove those patches manually.

Normally system won't store any patches under /usr directory. It will be under /var/adm/sw. Make sure that you are not doing anything which will harm the system.
