Reclamation of our offsite copy pool is taking forever. Right now, we have
200+ volumes in that pool. Normally, threshold is set at 60% and I get
maybe 8 or 9 volumes returned after processing for 7 hours (on beefy AIX,
with TSM at 5.1.5). Lately I've tried setting the threshold at 99, then
98, then 97, etc., but I don't see much improvement in overall freeing up
of tapes. It appears that most of the time is taken up with mounting input
volumes. Even though we have a 3494, I'd say 80% of the time is spent
waiting for tape mounts. Is there any way to get space reclamation to free
up offsite tapes faster? Note, for my onsite tape pool, I do not see this
problem (e.g., I can easily free up 30 tapes in 5 hours or less).
