ZMCS Maps
•
ON indicates that the label information is written or changed without checking
for an existing tape label and without checking the available system search
space for a duplicate name.
•
OFF indicates that the label information is written after the label check
completes and if no duplicate tape is in the available system search space.
ZMCS-MAP-ALTER-DISKFILE
MEDIASRV includes this extensible structured token in ALTER DISKFILE commands
to describe changes to disk files altered by this command. ZMCS-MAP-ALTER-
DISKFILE is based on ZMCS-DDL-ALTER-DISKFILE, which is defined as:
ZGENERATION
corresponds to the GEN parameter of the MEDIACOM ALTER DISKFILE
command.
A number from 1 to 32767 is used as an absolute value to denote which
generation of the tape file entry to alter.
ALL denotes that all generations of the tape file entries that own a disk file entry for
the disk file name are changed.
ZGENISPRESENT
contains a status of either TRUE or FALSE. ZGENISPRESENT must contain a
TRUE status whenever an absolute value is present for ZGENERATION.
ZPHYSICALCOPY
corresponds to the PHYSICAL parameter of the MEDIACOM ALTER DISKFILE
command. ZPHYSICALCOPY refers to the sequential order in which backup tape
sets were created by BACKUP and BACKCOPY.
A number from 1 to 99 denotes a physical copy number of a disk file entry to
change.
A status of ALL denotes a change to a disk file entry for all physical copies.
