Error description
Post Deduplication: It is now possible to have a dedup chunk logically removed from the primary pool though the chunk still exists. Chunk dependencies are only checked within its pool before deletion. An offsite volume bitfile/chunk may now be linked to a primary chunk that no longer exists thus requiring dedup'd offsite volumes to be brought onsite for reclamation. Customer/L2 Diagnostics: None Platforms affected: TSM 6.1, 6.2 all platforms Initial Impact: Low Additional Keywords: dedup ZZ61 ZZ62 vol chunk extent

Problem conclusion
The message text for ANR1163W will be updated with the following information: In the Explanation section, the following paragraph will be added: "If the files in the storage pool are deduplicated, they could be skipped due to the unavailability of an on-site copy. This can occur if the file has been logically deleted from all other storage pools due to policy settings but must remain in the offsite storage pool due to deduplication dependencies." In the User Response section, the following sentence will be added: "If the storage pool is deduplicated and all primary storage pool volumes are available, this is the recommended solution." This is the entire message now, including the added text: Explanation During processing of a MOVE DATA command or reclamation, the server determined that the indicated offsite volume contained one or more files that could not be moved. One or more files could not be copied from the other available volumes. The server might not move some files if the storage pool is collocated and the volume being moved or reclaimed contains files that require different output volumes. The server will skip these files and no messages are issued identifying the skipped files. The files are skipped to honor the collocation attribute of the storage pool. If the files in the storage pool are deduplicated, they could be skipped due to the unavailability of an on-site copy. This can occur if the file has been logically deleted from all other storage pools due to policy settings but must remain in the offsite storage pool due to deduplication dependencies. System action None. User response Check for messages that indicate why files could not be moved. To complete the move operation, you have several options; Bring the volume back on-site and reissue a MOVE DATA command to reclaim the volume. If the storage pool is deduplicated and all primary storage pool volumes are available, this is the recommended solution. Make the primary volumes available and reissue a MOVE DATA command to reclaim the volume. Delete the files by using the DELETE VOLUME command. If the server is skipping files to honor the collocation attribute of the storage pool, run the MOVE DATA command, or wait until reclamation runs again. In either case, the server will move files to the appropriate output volumes until the volume being moved or reclaimed is empty. It might take more than one attempt to totally empty the volume. Recommendation: Apply fixing level when available. This problem is currently projected to be fixed in levels 6.1.4 and 6.2.2. Note that this is subject to change at the discretion of IBM. Affected platforms: AIX, HP-UX, Sun Solaris, Linux, and Windows.
