Error description
When GENERATE BACKUPSET and SPACE RECLAMATION run at the same time in TSM Server 6.x, GENERATE BACKUPSET completes without any errors even though it actually stores incomplete set of backup files into the backup set. Here is steps we found the problem. 1. Do backup file01 in volume vol01 2. Do backup file02 in volume vol02 3. Do backup file03 in volume vol02 4. Delete backup file02 from vol02 5. Run SPACE RECLAMATION for vol02 and GENERATE BACKUPSET at the same time. 6. GENERATE BACKUPSET is successfully done with no error. 7. Run QUERY BACKUPSETCONTENTS, then notice only file01 is in the backup set even though file01 and file03 should be there. GENERATE BACKUPSET fails to retrieve file03 when it is just deallocated by SPACE RECLAMATION. The expected behavior is that GENERATE BACKUPSET should fail with an error because it could not write the file to the backup set. Versions affected: TSM Server 6.x on all supported platform Additional Keywords None. Additional L2 info: The following trace is found in the trace file with BKSET BFRTRV. --- hh:mm:ss [nnn][bfrtrv.c][1872][bfRtrv]:Exiting, bitfile nnnnnn, rc=4. --- This trace indicates the GENERATE BACKUPSET could not retrieve the file because it was already deallocated by the reclamation. Initial Impact: Medium
Local fix
Avoid running GENERATE BACKUPSET when any other data movement processes are running.
