            Hello,

            is there any way to recall a migrated file back to a regular
            state
            (other than renaming a file)? I would like to free some space
            on an external pool (TSM), that is being used by migrated
            files.
            And it would be desirable to prevent repeated backups of an
            already backed-up data  (due to changed ctime/inode).

            I guess that you can acheive only premigrated state with
            dsmrecall tool
            (two copies of file data - one on GPFS pool and one on external
            pool).
            Maybe deleting 'dmapi.IBMPMig' xattr will do the trick but I
            don't think
            it's safe, nor clean :).

            Thank you in advance,
