Full Discussion: cfgmgr and hdisk number allocation
Operating Systems AIX cfgmgr and hdisk number allocation Post 302095439 by fosteria on Tuesday 7th of November 2006 05:16:08 AM

Thanks a million guys; I think you have got to the 'nub' of this particular problem. Our FC scripts currently call rmdev with a '-d' flag when they disable the FC volumes, completely removing the definitions each time. I guess this needs changing.

Do you have any links or good examples of FC enable/disable scripts for AIX ? I'm thinking ours may be lacking in other areas too.

Don't worry Funksen; I understood exactly what you were saying - thanks again.

cfgmgr

Hi All, I remember my old senior mentor in AIX that cfgmgr should not be terminated on your console. Because if it's terminated in the middle, the odm might get corrupted. Is that true for AIX 5.x? Regards, itik (1 Reply)

       pvchange - change attributes of a physical volume

SYNOPSIS

       pvchange  [--addtag  Tag]  [-A|--autobackup y|n] [-d|--debug] [-f|--force] [--deltag Tag] [--metadataignore y|n] [-h|-?|--help] [-t|--test]
       [-v|--verbose] [-a|--all] [-x|--allocatable y|n] [-u|--uuid] [PhysicalVolumePath...]

DESCRIPTION

       pvchange allows you to change the allocation permissions of one or more physical volumes.

OPTIONS

       See lvm for common options.

       -a, --all
	      If PhysicalVolumePath is not specified on the command line all physical volumes are searched for and used.

       --metadataignore  y|n
	      Ignore or un-ignore metadata areas on this physical volume.  If metadata areas on a physical volume are ignored, LVM  will  not  not
	      store metadata in the metadata areas present on this Physical Volume.

       -u, --uuid
	      Generate new random UUID for specified physical volumes.

       -x, --allocatable y|n
	      Enable or disable allocation of physical extents on this physical volume.

Example
       "pvchange -x n /dev/sdk1" disallows the allocation of physical extents on this physical volume (possibly because of disk errors, or because
       it will be removed after freeing it.
