Troubleshooting
Problem
Library QUSRBRM fails to restore source partition after successful BRMS backup on target partition, during a STRFSFLASH while using PowerHA Tools Full System FlashCopy Manager Toolkit Manager (FSFC).
Symptom
Error message IAS0741 'Unknown error restoring QUSRBRM' can be seen in the QZRDIAEXT2 joblog on the source partition during the restore of QUSRBRM.
Diagnosing The Problem
Check the QZRDIAEXT2 joblog on the source partition for the following:

To module . . . . . . . . . : QZRDIAFFC2
To procedure . . . . . . . : restoreQUSRBRM
Statement . . . . . . . . . : 55
Message . . . . : Unknown error restoring QUSRBRM. (C I R)
Cause . . . . . : The Full System Copy Services Manager has attempted
restore QUSRBRM. View the joblog to determine the error and respond to this
message with R to retry the restore and continue with the Flash Copy
process. If the problem cannot be resolved, respond with C to cancel the
process. You can ignore the error and continue with the processing by
responding with an I but not all BRMS objects may be restored. If the
operation is canceled QUSRBRM on this partition will not be restored from
the target partition and BRMS will remain in Flash Copy mode.
Resolving The Problem
The PowerHA Tools Full System FlashCopy (FSFC) toolkit saves QUSRBRM to virtual tape and an image catalog which is used to transfer QUSRBRM from the target partition (where the BRMS backups occur) to the source partition (Production). Message CPF41B3 implies that there should be another virtual tape to complete the restore of QUSRBRM. The size limit of a stream file is 1TB, which makes the size limit of a virtual tape 1TB. If QUSRBRM is too large to fit on one virtual tape the SAVLIB process will automatically create another virtual tape and complete the save. However, the FSFC toolkit only transfers one virtual tape back from the target partition to the source partition by design. This is a limitation and there are currently no plans to change this.
Check the size of QUSRBRM. If it's larger than 1TB, the solution is to make QUSRBRM smaller. Typically this means keeping less object level detail. Please refer to document: The existing object level detail can be "trimmed" using STRMNTBRM or RMVMEDIBRM, both of which contain parameters that can be used to delete specific object level detail after it is a certain age. Even if the underlying backup volumes will not be expired.
