When used with the --autocorrect and --match-media options, the FSC vs. media check
invalidates the results of a reorganization scan.
To perform the FSC consistency check, use the following command:
NOTE: Depending on the inconsistency type, for example, if a reference to a file on the FSE medium is
missing in the File System Catalog, or if there are inconsistencies in NSC, you can use the automatic
correction option --autocorrect to update FSC (including NSC) with missing information.
When fsecheck is used with the --match-media option, the automatic correction process removes all
entries in the File System Catalog that have not been found in the belonging Fast Recovery Information
blocks on FSE media. An entry in this context means information about the location on the FSE media of
any of the following: file generation, file copy, file split.
In case of other inconsistency types, you need to perform a FSC recovery. For details, see ”File System
Catalog recovery” on page 186.
Inconsistency types
Reported inconsistencies in the FSE check log can be any of the following:
• missing in FSC
A file is recorded as missing in FSC when the file ID exists on the HSM file system, but is not recorded
in FSC. Probably the file has not been successfully migrated yet, and you need to migrate it manually
using the command fsefile --migrate FileName.
• missing on media
• no NSC
• mismatch report, such as:
•Wrong file size
• Wrong file name
• Wrong owner-ID
•ADS name
•Not last NSC
