ALTER DISKFILE Command (Super Group Only)
ALL
changes all generations of the tape file entries that own a disk file entry for
disk-file-name.
STATUS { INVALID | VALID }
is the status of the disk file entry:
INVALID
This entry represents a disk file that RECOVER DISKFILE should not use.
VALID
This entry represents a disk file that RECOVER DISKFILE can use.
FILECAT \node.file-catalog-name
is the logical name of the file catalog that owns the entry to alter. Include \node
when the file catalog is not on your current default node. The default is the name
set by the FILECAT command.
This parameter is required if no value is available from the MEDIADEFS defaults or
previously set as a MEDIACOM session default. (See the ENV Command on
page 2-89.)
LOGICAL { logical | ALL }
refers to which copy of a tape set created from a parallel BACKUP or a parallel
BACKCOPY run to change. (When such tape sets are created, one set is
cataloged as logical copy 1, and the other set as logical copy 2.)
This option specifies which logical copy is associated with tape-file-id (and
disk-file-name):
logical
changes the disk file entry for logical copy 1 or logical copy 2. Specify
logical as 1 or 2. The default is 1.
ALL
changes the disk file entry for logical copy 1 and logical copy 2.
PHYSICAL { physical | ALL }
refers to the sequential order in which backup tape sets were created by BACKUP
and BACKCOPY.
Two identical tape sets created by a parallel BACKUP or a parallel BACKCOPY
have the same physical copy number but different logical copy numbers (1 and 2).
