Changing the Configuration Volume From $SYSTEM
to an Alternate Disk
Changing the Configuration Volume
From $SYSTEM to an Alternate Disk
The configuration files should already exist on the new alternate configuration volume
before you do this procedure. (The configuration files exist as a result of
BACKUP/RESTORE operations, for example.) Note that this procedure replaces your
existing TMF configuration with the new configuration specified in the configuration
subvolume on the alternate disk.
1. Issue a TMFCOM STOP TMF command.
2. Make sure the configuration files already exist on the alternate configuration
volume.
3. Issue a TMFCOM ALTER TMF, CONFIGVOL command, specifying the alternate
configuration volume name. TMF requests a user confirmation before proceeding.
This command performs an implicit STOP TMF, ABRUPT operation.
4. Issue a TMFCOM INFO TMF command to verify that the volume specified
in Step 3 is the new configuration volume.
5. If any disk volume configured as an audit-trail active volume, overflow volume, or
restore volume in the new configuration has old audit-trail files in the ZTMFAT
subvolumes, you must purge the old files or move them out of the ZTMFAT
subvolume before TMF can start. To purge or move the old files, use SNOOP
PURGEAUDIT or RENAMEAUDIT.
6. Issue a TMFCOM START TMF command.
Changing the Configuration Volume From One Alternate Disk to
Another
The following procedure changes the configuration volume from one alternate disk
volume to another and back again. In this procedure, $SYS02 and $TEMP are used
as examples of disk volumes, and the purpose of changing the configuration volume is
to perform disk maintenance on $SYS02.
1. If TMF is running, issue a TMFCOM STOP TMF command to perform an orderly
shutdown.
2. Issue a FUP RENAME command such as the following:
FUP RENAME $SYS02.ZTMFCONF.*, $SYS02.ZTRENAME.*
3. Issue a TMFCOM STOP TMF, ABRUPT command. At this point $TMP has closed
the files in ZTRENAME and created some empty configuration files in ZTMFCONF.
4. Copy the configuration files from $SYS02.ZTRENAME to the subvolume
ZTMFCONF on the second alternate disk:
FUP DUP $SYS02.ZTRENAME.*, $TEMP.ZTMFCONF.*
