Error description
A timing problem exists where an attempt to retrieve data from a container storage pool may fail if the retrieval operation is performed shortly after the data has been backed up, archived, replicated or protected. Affected retrieval operations include PROTECT STGPOOL, REPLICATE NODE, AUDIT CONTAINER, and client retrievals. The failure occurs because the retrieval operation attempts to access data that has not yet been flushed to media. The following error is generated in the activity log when this condition occurs: ANR2818E A consistency check failed on container /tsm/container/10/0000000000009999.dcf with error 4800. (Note: error 4800 can also be error 4801, error 4802 or error 4803) Corresponding chunk header errors are also recorded in the dsmffdc.log file: [ FFDC GENERAL_SERVER_ERROR ]: (sdutil.c:4462) Chunk Header Invalid Signature chunkId: 5702387903525131283 Container: /tsm/container/10/0000000000009999.dcf Offset: 36929536 After the ANR2818E error has occurred, a subsequent PROTECT STGPOOL operation will identify one or more damaged extents on the affected container: ANR4847W PROTECT STGPOOL detected an extent with ID 5702387903525131283 on container /tsm/container/10/0000000000009999.dcf that is marked damaged Because the initial ANR2818E error occurred as the result of a timing problem, performing an audit of the affected container after the data has been successfully flushed to media will result in the extent(s) previously marked as damaged becoming undamaged: ANR2017I Administrator ADMIN issued command: AUDIT CONTAINER /tsm/container/10/0000000000009999.dcf ANR4886I Audit Container (Scan) process started for container /tsm/container/10/0000000000009999.dcf (process ID 165). ANR4891I AUDIT CONTAINER process 165 ended for the /tsm/container/10/0000000000009999.dcf container: 1728 data extents inspected, 0 data extents marked as damaged, 1 data extents previously marked as damaged reset to undamaged, 0 data extents marked as orphaned, and 0 data extents previously marked as orphaned reset to unorphaned. In the event of a server crash prior to the data being successfully flushed to media, then the above ANR2818E error message may not be seen, but damaged extents may be detected on one or more containers in the storage pool. In this situation, the affected extents are damaged and cannot be resolved via the AUDIT CONTAINER process. Versions Affected: IBM Spectrum Protect server versions 7.1.3 and higher Initial Impact: Medium Additional Keywords: directory container chunk header extent flush timing
Local fix
If the ANR2818E error is seen, quiesce all backup, archive, replication, and protect operations to the storage pool, wait for all of these sessions to end, and then perform an AUDIT CONTAINER on the affected container(s).
