Why Audit-Trail Files Stay Pinned on a Volume
tapes. Archive mode is allowed only if the audit trail for this data volume is configured
for audit dumping. See Changing the Data Volume Configuration on page 3-10 for
more information.
Reason: Might be needed to restart TMF
Meaning. This audit-trail file contains control information needed by TMF to restart
after a system failure. The control information is typically written to the current file
within 10 minutes, which clears this condition. If there is no audited activity, however,
control records are not generated; in this case, the condition remains until audited
activity resumes.
Action. If the status of this file does not change within 10 minutes and the output of
STATUS TMF commands indicates that audit activity is occurring, check the EMS log
for TMF errors.
Reason: Not dumped
Meaning. An audit dump process has been configured for this audit trail, and this file
has not yet been copied to dump media.
Action. Use the STATUS AUDITDUMP command to check on the audit dump process:
•
If the audit dump process was disabled, issue an ENABLE AUDITDUMP
command.
•
If an audit dump process is active and you are doing tape dumps, make sure that
all tape mount requests are satisfied.
•
If an audit dump process is active and you are doing disk dumps, make sure that
your disk has enough space for the audit-trail file.
See Maintaining Audit Dumps on page 4-1 for more information on maintaining audit
dumps.
Reason: Required by RDF
Meaning. the NonStop Remote Database Facility (RDF) requested the pinning of
the file on disk, and eventually will release the disk.
Action. If RDF will be down for a long time, you may want to use the RDFCOM
UNPINAUDIT command to release the pinned audit-trail file. The UNPINAUDIT
command can be issued only by members of the super user group. If the RDF
software version you are using does not support the UNPINAUDIT command, you
must stop and restart TMF to release the audit-trail file.
When you subsequently issue the START RDF command, RDFCOM asks TMF to
restore any necessary audit files from the archive media. However, if any of those
audit files are no longer available (because the online dumps that required them were
deleted by TMF RETAINDEPTH processing), RDF will be unable to start. In this case,
you must resynchronize the database protected by RDF.
