I use the following script to check reclaimable space by storage pool. The output lines are numbered, makes it easy to check a percentage and a line number to get a tape count.
#!/usr/bin/ksh # # This script checks reclaimable space in a tape storage pool # The list is displayed with line numbers and is sorted by # reclaimable space in descending order. # Check that a parameter is passed if [[ $# != 1 ]] then echo Usage: cr \<storage_pool_name\> exit 4 fi dsmadmc -id=<userid> -pass=<password> -displ=list "q vol stg=$1 f=d" | grep Reclaimable | sort -n -r -k 4 > $1.usage cat -n $1.usage | more rm $1.usage Regards, Jim Schneider -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Michael Roesch Sent: Tuesday, April 15, 2014 9:28 AM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] reclaimable tapes in a stgpool Hi, I'm using this query to see all tapes and how much reclaimable space they have in descending order. As we have a small library, this is suitable for us.
