I see the exact same thing on our TSM servers. After speaking to IBM they state that the hang is down to a component of the database not being able to respond during what ever process is running. During the start of a reclaim process the IO is heavy on the database and the TSM instance queues mounts for the volumes that it recognises are eligible for reclaim based on the percent that you have assigned the storage pool. If this is a massive amount then, this could take a while.
Does q mo hang as well? If it does not, then it suggests that the problem lies in the disk storage. If it does then more likely to be related to tape. What library firmware and drivers are running the library? Also check the following APAR: C47930 TSM SERVER MAY HANG ALL OPERATIONS REQUIRING ACCESS TO A SEQUENTIAL VOLUME AFTER RECLAMATION STARTS REPAIR STGVOL. IC47930 is fixed in levels 5.3.2.3 (available now) and 5.3.3. _____________________________ Ian Smith SAN/TSM Specialist -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Orville Lantto Sent: 28 February 2006 23:13 To: [email protected] Subject: [ADSM-L] Q STG hangs during reclamation We are having problems on a TSM server instance on AIX. Some simple commands such as "Q Stg" appear to hang, along with their sessions, while reclamation is in process. Other commands like "Q Pr' do not hang. The server is AIX 5.2.5 with six instances of TSM Server 5.3.2.0 on it. The disk is DS4300 with a 3584 tape library shared between the instances. Anyone have a guess as to why? Orville L.
