Commands and Responses
ZTMF-VAL-DVS-Down-Dirty
specifies configured volumes that are inaccessible, perhaps because of
device or process problems, but for which normal shutdown processing did
not complete successfully. A volume enters the downdirty state if it is down
(or goes down) during shutdown, or if data volume startup fails for any
reason.
When TMF cannot determine whether a volume is clean, the subsystem
assumes that it is dirty. Audited files on a dirty volume can contain both
logical and physical inconsistencies, but these are typically repaired by
volume recovery when the volume is restarted.
ZTMF-VAL-DVS-ShuttingDown
specifies configured volumes that are being shut down by the STOP TMF
command.
ZTMF-VAL-DVS-Disabling
Configured volumes being disabled for auditing by the DISABLE
DATAVOLS command.
ZTMF-VAL-DVS-Disabled
specifies configured volumes that are in either the disabled-clean or
disabled-dirty state. Disabled data volumes are not automatically restarted
each time they come up. Data volumes must be disabled before they can
be deleted from the configuration.
ZTMF-VAL-DVS-Disabled-Clean
specifies configured volumes that are disabled, and on which no updates
have been made to audited files since the volume last underwent a clean
shutdown. Audited files on volumes in this state do not contain any
inconsistencies.
ZTMF-VAL-DVS-Disabled-Dirty
specifies configured volumes that are disabled, but for which normal
shutdown processing did not complete successfully. A volume enters the
disabled-dirty state if it is disabled by a DISABLE DATAVOLS command
that includes the ZAbrupt field or by a TMFCOM command with the
ABRUPT option.
When TMF cannot determine whether a volume is clean, the subsystem
assumes that it is dirty. Audited files on a dirty volume can contain both
logical and physical inconsistencies, but these are typically repaired by
volume recovery when the volume is restarted.
