TSM Server 5.1.9.0 on AIX 5.2 ML-4 TSM Client mix of 5.1.6.0 and 5.1.7.0 mostly on Windows
This morning I found a primary storage pool tape "pending" as the result of reclamation that launched spontaneously just after midnight. The logs show no evidence of anyone issuing any commands to launch that operation. I'm trying to figure out how that happened since we maintain pretty tight control over the TSM maintenance processes. Specifically, on our system, maintenance occurs weekly. On Monday at 9:00 am we run expiration which of course triggers reclamation of the primary pools. Expiration completes late Monday afternoon with all primary reclamation completing sometime late Monday night to early Tuesday morning. We leave our copypool reclaim point set at 100% throughout this process. On Tuesday at 6:00 pm we launch copypool reclamation, after which the reclaim point is returned to 100%. That is our entire maintenance schedule. No other expirations or reclamations are scheduled to occur at any time. So what could have provoked a primary tape reclamation at midnight, approximately nine hours before the start of the regular maintenance cycle? Just curious.
