Error description
Tivoli Storage Manager server IDENTIFY DUPLICATES process(es) will not scan data ingested after the processes were started if the IDENTIFYPROCESS parameter on the storage pool definition is set to 0. This issue becomes especially apparent if IDENTIFY DUPLICATE processing is running with an infinite duration. Administrators affected by this issue are likely to notice that their IDENTIFY DUPLICATES process(es) initially scanned data, but then went IDLE and remain in that state indefinitely, despite new data being ingested into the storage pool. If the IDENTIFY DUPLICATES process(es) are not analyzing newly ingested data, then the server-side deduplication ratio will likely be lower than expected. Customer/L2 Diagnostics: None. Initial Impact: Medium Tivoli Storage Manager Versions Affected: All supported Tivoli Storage Manager server users of file- pool based server data deduplication. Additional Keywords: TSM DEDUP DEDUPE DEDUPLICATION RATIO IDENTIFY ID PERCENT IDENTIFYPROCESS STG STGPOOL STGP SPECTRUM PROTECT DUPLICATE
Local fix
To mitigate this issue, the IDENTIFYPROCESS parameter on the storage pool definition should be updated to match the NUMPROCESS parameter value used on the IDENTIFY DUPLICATES command. Once this update is made, recycle all existing IDENTIFY DUPLICATES processes (cancel the existing processes, and restart them).
