Error description
Problem Description: Reservation conflicts can occur on a library manager when a library client cannot confirm to the library manager that a drive is still in use due network issues. The root cause is the network problem which needs to be fixed outside of Tivoli Storage Manager itself, but further analysis showed that the error recovery procedure on the library manager is using wrong timestamps to recover from a network issue. Customer/L2 Diagnostics: The actlog of the library manager shows ANR8469E Dismount of 3592 volume 123456 from drive ABC (/dev/ABC) in library IBMTS3500 failed. ANR8475I Dismount of volume 123456 failed. It may still be in the drive. and the actlog of library client shows ANR0454E Session rejected by server LMTSM, reason: Communication Failure. ANR8926W An Error was encountered while confirming the use of drive ABC in library IBMTS3500. ANR8213W Session open with 10.255.255.001 timed out. ANR0454E Session rejected by server LMTSM, reason: Communication Failure. ANR9778E Unable to establish a communication session with the primary library manager. A library manager trace with trace flags PVR MMS NA enabled shows that the wrong timestamp in the error recovery procedure is being used. 11:37:00.652 [2108410][smlshare.c][5311][DoConfirmMP]:Confirming mount point for class 3592, libName IBMTS3500, devType 25, format 0, mpToken 8, mpTimeStamp 09/15/0113 09:27:13, for drive ABC, volume 123456. 11:37:00.652 [2108410][pvrmp.c][2031][pvrConfirmSharedMountPoint]:Confirming shared mp 8 for TSMCLIENT - class 3592, library IBMTS3500, devType 25, format 0, drive ABC, volume 123456, time stamp 09/15/13 09:27:13. The drive is confirmed in use but uses the library client's time stamp ( 09/15/13 09:27:13) not the library server's ( 11:37:00.652 ) like it should be. As result, the library manager attempts to reclaim the drive which is still in use by the library client because the last confirmed time is not in the last minute of library manager.
