With powerpath you don't need to drop the disks - just varyoffvg each volume group and reboot. A utility is provided to put the rootvg under powerpath as well.
As long as 1 disk is running under MPIO you won't be able to uninstall the device driver - however this isn't recommended practice for AIX, as best practice is to have all your device drivers loaded in case you have to restore after a disaster.
Would you mind telling us why you want to uninstall MPIO?

Hello,
I'm working on a Solaris 9/Sparc machine and it has the Solaris 10 version of Perl (5.8.8) installed on it, which always requires all kinds of library files that Solaris 9 doesn't come with. I think the best way to do is to uninstall this wrong version and install the correct Solaris 9... (1 Reply)

Hi
I would like to ask what the benefits are of changing from RDAC to MPIO when connecting to a DS4000 on AIX 5.3? I have heard that IBM MPIO "might" support more than 1 active path to a LUN when connecting to a DS4800 through more than 1 host connection on the same AIX client. I understand that... (8 Replies)

On a particular LPAR, I was running AIX 5.3 TL 3. On Monday I did an update of the LPAR to 5.3 TL 9 SP2. The install was smooth, but then I ran into a problem.

gpt-uninstall
GPT-UNINSTALL(8) User Contributed Perl Documentation GPT-UNINSTALL(8)
NAME
gpt-uninstall - Uninstall any GPT package.
SYNOPSIS
gpt-uninstall [--force --help -name ] pkgname-flavor-pkgtype
DESCRIPTION
gpt-uninstall will uninstall a package from the system.
OPTIONS
-force This will force actions to take place.
-native Use native package manager (Only works with rpm).
pkgname-flavor-pkgtype
Expression describing the packages that should be removed.
-help Print a brief help message and exits.
-man Prints the manual page and exits.
-version
Prints the version of GPT and exits.
EXAMPLES
gpt-uninstall -name=foo
removes all flavors and package types with the name "foo".
gpt-uninstall foo
Also removes all flavors and package types with the name "foo".
gpt-uninstall 'foo-*-*'
A third way of typing the same uninstall. Note the single quotes.
gpt-uninstall '*-noflavor-*'
Remove all of the packages with a 'noflavor' build flavor.
gpt-uninstall '*-*-*'
Remove all packages. Note that files generated by gpt-postinstall will not be removed
BUGS
Currently the flavor check that gpt-uninstall uses only works if the flavor is installed by gpt-build. And so for example:
gpt-uninstall foo-gcc32-*
will not work. The work around is to uninstall the packages individually using something like:
gpt-uninstall -name=foo -flavor=gcc32 -pkgtype=pgm
Or use a wild card for the flavor to uninstall all flavors of the package.
gpt-uninstall foo-*-*
