File migration inhibit

The file owner can define via the catalog entry whether or not the file is to be exempted from migration. This is done via the MIGRATE operand of the CREATE-FILE or MODIFY-FILE-ATTRIBUTES command:

• MIGRATE=*ALLOWED allows a file to be migrated (default)

• MIGRATE=*INHIBITED prohibits the migration (Exception: see "Files typically exempted from migration").

The HSMS administrator can, however, state that MIGRATE= *INHIBITED files can be migrated.

User IDs that have the right to make physical allocations also have the MIGRATE=*FORBIDDEN option. This inhibits migration completely. A note is entered in the catalog entry of the file and can be output using the SHOW-FILE-ATTRIBUTES command.
