Error description
During reclamation or move data, the server reconstructs bitfiles. During this process there can be a situation where the server using "query stgpool" will incorrectly report the number of 'Moved Bytes' as a size that way exceeds the size of the storage pool being reclaimed or of the volume being moved. For example: query stgpool Process Process Description Process Status Number -------- -------------------- ----------------------------------- 3,781 Space Reclamation Offsite Volume(s) (storage pool STGPOOL), Moved Files: 4760, Moved Bytes: 16,383 PB, Deduplicated Bytes: 0 KB, Unreadable Files: 0, Unreadable Bytes: 0 KB. Current Physical File (bytes): None Current output volume(s): 123456L3. Notice Moved Bytes is 16,383 PB but in this case storage pool has capacity of 540,170 GB Level 2 diagnostics: A server trace with DFMOVE AFMOVE ASVOL flags will show total bytes reducing until it would have hit a negative number and thus reports the huge number. 09:15:54.035 [65][dfmove.c][1890][DfTransferBitFile]:Reconstructed bitfile 6560299265, rc = 0. 09:15:54.036 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 1 files, total files 233. 09:15:54.036 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 1548 bytes, total bytes 164605. 09:15:54.039 [65][bfcreate.c][5391][BfReconstruct]:BfGetAggrAttributes returned rc=0 for targetBfId=6560299291. 09:15:54.047 [65][dfmove.c][1890][DfTransferBitFile]:Reconstructed bitfile 6560299291, rc = 0. 09:15:54.047 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 5 files, total files 238. 09:15:54.047 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 6761 bytes, total bytes 167592. 09:15:54.059 [65][dfmove.c][1900][DfTransferBitFile]:Copied bitfile 6560308485, rc = 0. 09:15:54.059 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 1 files, total files 239. 09:15:54.059 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 822 bytes, total bytes 164640. 09:15:54.062 [65][dfmove.c][1900][DfTransferBitFile]:Copied bitfile 6560310602, rc = 0. 09:15:54.063 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 1 files, total files 240. 09:15:54.063 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 822 bytes, total bytes 161688. 09:15:54.075 [65][dfmove.c][1900][DfTransferBitFile]:Copied bitfile 6560310611, rc = 0. 09:15:54.075 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 2 files, total files 242. . . 09:15:54.627 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 646 bytes, total bytes 3557. 09:15:54.636 [65][dfmove.c][1900][DfTransferBitFile]:Copied bitfile 6559793514, rc = 0. 09:15:54.636 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 4 files, total files 335. 09:15:54.636 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 2443 bytes, total bytes 2226. 09:15:54.643 [65][dfmove.c][1900][DfTransferBitFile]:Copied bitfile 6559793878, rc = 0. 09:15:54.644 [65][dfmove.c][1930][DfTransferBitFile]:Transferred 1 files, total files 336. 09:15:54.644 [65][dfmove.c][1932][DfTransferBitFile]:Transferred 645 bytes, total bytes 18446744073709550713. <= this would have been negative number Tivoli Storage Manager Server Versions Affected: 7.1.x on all supported platforms Initial Impact: Low Additional Keywords: TSM reclaim reclamation size moved bytes move moved data
