Restoring the ZTMFCONF Subvolume
Restoring the ZTMFCONF Subvolume
If the TMF configuration subvolume, ZTMFCONF, becomes damaged or corrupted,
TMF could shut down abruptly and not be able to restart. Particularly significant to the
TMF environment, all audit-trail configuration information is lost. Because the
ZTMFCONF subvolume typically resides on $SYSTEM, it is likely that the $SYSTEM
volume is also damaged or corrupted, which requires a complete system reload.
If your system’s configuration volume is on $SYSTEM, follow the procedure below to
recover the ZTMFCONF subvolume. The ZTMFCONF subvolume can reside on any
volume in the system. If the configuration subvolume on your system is on a volume
other than $SYSTEM, use that volume name in the procedure that follows, and skip
Step 1.
Use the following procedure to recover the ZTMFCONF subvolume:
1. If only one drive of your mirrored system disk ($SYSTEM) is usable, the system
automatically uses that drive.
If neither drive of your mirrored system disk is usable, you must restore your
system disk from the system image tape (SIT) that was created when the system
was installed.
Refer to the recovery procedures established for your system and the appropriate
system operations manual for more information.
2. Rename the existing TMF configuration subvolume.
The existing configuration files are either damaged or, if you introduced a new
$SYSTEM disk, the files represent a new, empty configuration that TMF created
when the system was reloaded. These files need to be moved from the
configuration subvolume so the correct files can be restored.
>FUP RENAME $SYSTEM.ZTMFCONF.*, $SYSTEM.PURGEME.*
3. Restore the ZTMFCONF subvolume from the latest backup on archive media.
4. Issue a STOP TMF, ABRUPT command.
TMF opens and reads the configuration files restored in Step 3.
5. If you altered the AUDITTRAIL, AUDITDUMP, CATALOG, or PROCESS
configuration after the last backup of ZTMFCONF, redo those changes.
The ALTER AUDITTRAIL, AUDITDUMP OFF command cannot be performed until
TMF is restarted. However, the ALTER AUDITTRAIL, AUDITDUMP ON command
should be performed now, if applicable.
If you performed a DELETE TMF operation and restarted TMF since the last
backup of ZTMFCONF, or if you have any difficulty making the TMF configuration
match what it was immediately before the damage occurred to the configuration
subvolume, contact the Global Customer Support Center (GCSC) or your service
provider.
