command. ZPHYSICALCOPY refers to the sequential order in which backup tape
sets were created by BACKUP and BACKCOPY.
A number from 1 through 99 denotes a physical copy number of a disk file entry to

A number 1 or 2 denotes a change to the disk file entry for either logical copy 1 or
logical copy 2. (The default is 1.)
A status of ALL denotes a change to the disk file entry for both logical copy 1 and
logical copy 2.

date that replaces the current expiration date for the entry.
A valid value is a number in the range of 1 through 9999.
