Making Audit Dumps
For a dump to tape, the audit dump process locates the audit-trail file that is ready to
be dumped and gets the name of a scratch tape from the TMF catalog. If the tape is
not mounted, the labeled-tape process generates an event message like the following:
$ZSVR: 0033 MOUNT TMF018 WITH RING
"TMF Audit-Dump ($X025) of $MAT.ZTMFAT.AA000047. Tape #1."
The labeled-tape process sends different mount requests, depending on how the audit
dump process is configured:
You can respond to the tape request by mounting the requested tape or mounting any
TMF scratch tape: the audit dump then begins. When the audit dump process
completes successfully, it generates an event message like the following:
11:47 24FEB02 147,00,048 TMF *0208* AuditDump:
Audit trail $MAT.ZTMFAT.AA000047 dumped to tape.
Dump serial number 77.
If you need more scratch tapes, use the ADD TAPEMEDIA command (see Section 6,
The TMF Catalog, for more information).
If you are doing audit dumps to disk, supply the following information in an ALTER
AUDITDUMP command:
•
The disk volume to which audit-trail files will be copied.
•
A two-character prefix to which the audit dump process appends a six-digit number
to name the audit dump subvolumes. This number is based on the dump serial
number, which TMF generates whenever a TMF dump is started.
The audit dump process locates the audit-trail file that is ready to be dumped and
generates the dump name from the dump serial number and the two-character prefix.
For instance, dump serial number 145 would be copied to the volume specified in the
audit dump configuration as $volume.ZT000145 if the prefix was defined as the
default of ZT. See the TMF Planning and Configuration Guide for information on
configuring the audit dump process.
