Error description
A data movement, or data copy, process might end in failure when processing a volume located in a deduplicated storage pool. The following error would be reported within the failing process: ANR4895E Deduplicated bitfile 123456789 on volume /volume01.dsm has invalid links. The cause of the ANR4895E message and invalid termination of the process, are the existence of duplicate aggregates being stored in the same storage pool. These files contained within those aggregates have conflicting references in the deduplication catalog of the Tivoli Storage Manager server. This is not a deduplication referential integrity problem but rather an error in the server for which the server is not properly choosing the right deduplication information for each aggregate. Customer/L2 Diagnostics: These invalidated links will not be reported via a the VALIDATE EXTENTS utility. To check if this APAR does match, the following can be done for the reported bitfile from the ANR4895E error: ANR4895E Deduplicated bitfile 123456789 on volume /volume01.dsm has invalid links. Here is the affected bitfile 123456789. From a server command line: show bfo 123456789 Bitfile Object: 123456789 **Super-bitfile 123456789 contains following aggregated bitfiles, Bitfile Id, offset, length, active state or owner, link bfid AAAAAAAAAA 0 49004 ZZZZZZZZZZ BBBBBBBBBB 0 0 YYYYYYYYYY **Archival Bitfile Entry Bitfile Type: PRIMARY Storage Format: 22 Bitfile Size: 49068 Number of Segments: 1, flags: 3 Storage Pool ID: 5 Volume ID: 987 Volume Name: /volume01.dsm -> This returns here two aggregated bitfiles AAAAAAAAAA and BBBBBBBBBB SHOW BFO against this aggregated bitfiles returned the following: show bfo AAAAAAAAAA Bitfile Object: AAAAAAAAAA **Sub-bitfile AAAAAAAAA is stored in the following aggregate(s) Super-bitfile: CCCCCCCCCC, Offset: 0, Length 0, Deduped: F Super-bitfile: 123456789, Offset: 0, Length 49004, Deduped: F -> The bitfile AAAAAAAAAA has two Super-bitfiles CCCCCCCCCC is an "empty" chunk 123456789 is a base chunk show bfo BBBBBBBBBB Bitfile Object: BBBBBBBBBB **Sub-bitfile BBBBBBBBBB is stored in the following aggregate(s) Super-bitfile: CCCCCCCCCC, Offset: 0, Length 71895, Deduped: F Super-bitfile: 123456789, Offset: 0, Length 0, Deduped: F -> The bitfile AAAAAAAAAA has two Super-bitfiles CCCCCCCCCC is a base chunk 123456789 is an "empty" chunk In this case there are two "deleted" aliases in the same pool. Each alias contains a base chunk and an "empty" chunk.
