Operating Systems AIX Uninstall native MPIO driver on AIX Post 302415306 by ross.mather on Thursday 22nd of April 2010 08:00:02 AM

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?

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-*-* SEE ALSO
