Error description
A limitation about primary sequential storage pools used for deduplication is missing from the documentation. Some values for the AUTOCOPY and COPYSTGPOOLS / ACTIVEDATAPOOLS parameters are mutually exclusive when deduplication is enabled. Either there is no copy or active datapool defined, and therefore the autocopy parameter does not apply and its value is not checked, or a copy pool or active data pool is referenced and the autocopy parameter can only be set to NONE or MIGR. Otherwise no deduplication takes place for client backup sessions. This does not affect node replication processes. Tivoli Storage Manager Versions Affected: Tivoli Storage Manager Server 6.2 and later on all platforms Initial Impact: Medium Additional Keywords: zztsm dedup autocopy ANS4164W

Problem conclusion
In the Tivoli Storage Manager Administrator's Reference, the sections for "DEFINE STGPOOL" and "UPDATE STGPOOL" for sequential-file storage pools will be updated to provide the following instructions under the AUTOCOPY option: "If the AUTOCOPY option is set to ALL or CLIENT, and there is at least one storage pool that is listed in the COPYSTGPOOLS or ACTIVEDATAPOOLS options, any client-side deduplication is disabled." Affected platforms: AIX, HP-UX, Solaris, Linux, and Windows.
