Explanation: UNEXPIRED is an optional subparameter
of SELECT specifying a list of each dump volume that is part of a
valid dump copy and has not reached or passed its expiration date.
Dump volumes with a retention period of NONE are not included. The
following information is listed for each dump volume:
- Source volume serial number for each valid dump copy
- Dump volume serial number
- Unit type
- Expiration date
- Dump class
Defaults: None.
Note: - If DUMPCLASS(class) is also specified in the set of SELECT
options, only dump volumes assigned to the specified class are
listed.
- The UNEXPIRED subparameter of the SELECT parameter is relevant
only when volser is not specified with the DUMPVOLUME parameter.
The UNEXPIRED subparameter can be used in combination with the subparameters
AVAILABLE, DUMPCLASS, EXPIRED, NORETENTIONLIMIT, or UNAVAILABLE to
get a list of volumes that satisfy all the selection criteria.
