Error description
A tape mount request from a library client may fail as a result of a deadlock condition on the library manager. Errors similar to the following will be seen in the library manager's activity log: ANR0379W A server database deadlock situation has been encountered; the lock request for the mms universe lock, will be denied to resolve the deadlock. ANR9790W Request to mount volume *SCRATCH* for library client LIBCLIENT failed. The problem is most likely to occur when there are active LABEL LIBVOLUME, RELABEL and/or CHECKIN LIBVOLUME processes running on the library manager at the time the tape mount is requested. Platforms affected: All TSM Servers Customer/L2 Diagnostics: A trace (DEADLOCK flag) on the library manager will show that the deadlock condition occurs when one transaction is holding the 'mms universe' lock (lock type 23000), while trying to acquire the 'ic lock voltype' lock (lock type 77778). The other transaction is holding the 'ic lock voltype' lock and trying to acquire the 'mms universe' lock, as seen below: A Deadlock was found: Transaction 0:121244072. Waiting for Lock mode sLock on: Type=77778(unknown), NameSpace=19, Key='' Held by transaction 0:121244067 in mode xLock. Transaction 0:121244067. Waiting for Lock mode xLock on: Type=23000(mms universe), NameSpace=0, Key='' Held by transaction 0:121244072 in mode xLock. Additional Keywords: mms_universe ic_lock_voltype
