List STALE partitions across Volume Groups for each Logical Volume in AIX

List STALE partitions across Volume Groups for each Logical Volume in AIX

I wrote a tiny script that can report the number of stale partitions across multiple Volume Groups. If invoked with the -a flag the script will list LPs, PPs and Stale partitions for all Logical Volumes in all active Volume Groups. Using the -v flag only information for the specified Volume Group will be displayed.

Usage:

stale.sh -v rootvg
stale.sh -a

Sample output:

VG: rootvg   LV: hd5     LPs: 1      PPs: 2         STALE 0
VG: rootvg   LV: hd4     LPs: 6      PPs: 12        STALE 0
VG: rootvg   LV: hd2     LPs: 29     PPs: 58        STALE 0
VG: rootvg   LV: hd3     LPs: 4      PPs: 8         STALE 0
VG: rootvg   LV: hd1     LPs: 2      PPs: 4         STALE 0

The script is here:
