Hi Guys,
I'm hoping someone with a little more ACSLS experience than I might be able to point me in the right direction with this one. Fundamentally, I'm witnessing seemingly random failures when mounting volumes in an ACSLS-managed STK L700 library. A cart which fails to mount in one operation will mount successfully two minutes later. A drive which failed mount a tape will also successfully mount a tape at the next attempt. >From tracking this over a period of time, there appears to be no obvious pattern. O - TSM Server: 5.5.1.1 (Solaris 9) O - ACSLS 7.1.0 O - Library STK L700 populated with 18 x IBM-LTO3 FC-attached drives The error manifests itself in the TSM Server activity log as: O - ANR8855E ACSAPI(acs_mount) response with unsuccessful status, status=STATUS_LIBRARY_FAILURE. O - ANR1401W Mount request denied for volume L30161 - mount failed. On the ACSLS console I see: O - 2010-03-04 16:58:26 0 LSM 0, 0: Library error, Path unavailable Obviously, the causes the TSM process or session requesting the mount to fail. However, retrying the same TSM operation may well result in a successful mount of the very same cartridge; and the same tape drive may also successfully mount another tape shortly afterwards. I've only come to this TSM Server today and I can see that it's been experiencing this as far back as TSM's activity log goes. The only hit online that I've found so far that seems to fit is a posting on this list from back in 2000 where someone seemed to be witnessing the same: http://www.adsm.org/lists/html/ADSM-L/2000-08/msg00007.html Does anyone have any pointers as to where I might look next or any other info that might be handy to dig out?
