Using the SCF STOP DISK Command on Audit-Trail
Volumes
In the following example, the files per active-audit volume are increased to 6 in the
MAT configuration:
TMF 21> ALTER AUDITTRAIL MAT, FILESPERVOLUME 6
Adding Another Active-Audit Volume
Adding an active-audit volume increases the audit tail capacity by the number of files
configured to reside on each volume of an audit trail; if there is not enough disk space
for these files, the volume cannot be added.
If the active-audit volume is full, add another active-audit volume. In the following
example, a new volume, $AUD2, is added as an active-audit volume:
TMF 27> ALTER AUDITTRAIL MAT, ADDACTIVEVOL $AUD2
The ALTER AUDITTRAIL command can be issued only by members of the super user
group. See the TMF Reference Manual for instructions on using the ALTER
AUDITTRAIL command.
Using the SCF STOP DISK Command on Audit-Trail Volumes
An active-audit volume or an overflow-audit volume must contain no active or overflow
audit-trail files before you can bring it down using the SCF STOP DISK command.
TMF generates an error if you try to bring down an active or overflow audit-trail volume
that contains any files. If you must bring down such a volume, you can either issue a
STOP TMF command and wait for audited activity to cease, or you can eliminate the
overflow condition and delete the overflow volume from the TMF configuration; then
you can issue the SCF STOP DISK command for the volume.
Use the SCF STOP DISK command as described in the SCF Reference Manual for G-
Series RVUs.
Note. TMF is shipped from the factory with the $AUDIT disk volume configured as the active-
audit volume. You are free to retain $AUDIT for this purpose, replace $AUDIT with another
volume as the recipient of audit trails, or add other active-audit volumes to the configuration.
See also the information about the preconfiguration of data volumes under Adding New
Data Volumes on page 3-11.
Note. To add or delete an entire audit trail, or to change the audit-trail file size attribute, you
must delete the TMF configuration and reconfigure audit trails from the beginning. Deleting the
TMF configuration clears current transaction information, the data volume configuration, and
the TMF catalog. See the TMF Planning and Configuration Guide for information on these
operations.
Caution. Before bringing down an overflow-audit volume or a restore-audit volume, you must
delete this volume from your TMF configuration by using the ALTER AUDITTRAIL command.
If you do not perform this step, your next START TMF command will fail.
