Error description
The Tivoli Storage Manager (TSM) QUERY AUDITOCCUPANCY command may return inaccurate occupancy information depending on the sequence of backup/identify commands. Example scenario: Node A backs up 20 G of data. IDENTIFY DUPLICATES is run against Node A's data, but no duplicate chunks are found. Node B backs up 20 G of data, 10 G in common with Node A. IDENTIFY DUPLICATES is run against Node B's data, and it finds the common chunks with Node A's data. Storage Pool Reclamation is run. Q AUDITOCC shows 20G of data used by Node A, and 10G by Node B. Now, reverse the order of backups: Instead of Node A first, then Node B, assume it was Node B first, then Node A. In this case Q AUDITOCC shows 10G for Node A, and 20G for Node B. QUERY AUDITOCCUPANCY returns different results depending upon who backs up data first. Tivoli Storage Manager Versions Affected: 6.1 Initial Impact: Medium
Local fix
issue a SELECT against the OCCUPANCY table, using the SUM() function and GROUP BY as such: select node_name,sum( logical_mb ) as "SpaceInMB" from occupancy where stgpool_name='POOL1' or stgpool_name='POOL2' group by node_name add an "OR STGPOOL_NAME='POOL'" clause for each primary pool
