DELETE DUMPS
SERIAL serial-number
directs this DELETE DUMPS command to remove the catalog entries only for
dumps with the specified serial number. You can obtain information about dump
serial numbers by using the INFO DUMPS command or by examining reports
produced for an audit or online dump.
Security Restriction
You can issue the DELETE DUMPS command only if you are a member of the super
user group.
TMF State Requirement
Before you can enter the DELETE DUMPS command, TMF must be started.
Usage Guidelines
You can specify that entries for certain files in a dump having a particular serial number
are deleted from the catalog. In this case, other entries for files having the same serial
number remain in the catalog.
When you enter the DELETE DUMPS command, the status of each dump you select
for deletion is changed from ASSIGNED (needed for recovery) to RELEASED (not
needed for recovery) in the TMF catalog. The dump entries for a specific medium
(tape reel or disk subvolume) remain in the catalog, however, until all dump files on
that medium are marked either RELEASED or INVALID; then TMF removes all dumps
on that medium from the catalog and performs the following operations on the medium
itself:
•
For a tape medium, TMF marks the appropriate tape reels as either RELEASED or
SCRATCH, depending on the setting of the RELEASED catalog configuration
option.
•
For a disk medium, TMF purges the files containing the dumps.
As long as other valid (ASSIGNED) dumps exist on a medium, that medium retains its
ASSIGNED status. To display the status of the dumps on an ASSIGNED medium,
issue the INFO DUMPS command with the DETAIL option; the resulting display shows
which dumps are ASSIGNED, RELEASED, or INVALID.
Specifying DELETE DUMPS *.*.* without the SERIAL option deletes all dump entries in
the TMF catalog; therefore, when you enter this command, TMFCOM prompts you to
verify that you indeed want to take this action. To confirm your intent, respond to the
prompt by entering YES; TMF then deletes the dump entries. To prevent this deletion,
enter NO; TMF prompts you for another command.
