ADD AUDITTRAIL
ACTIVEVOL[S]
specifies the disk volume that holds the audit-trail files. If ACTIVEVOL[S] was 
specified in a previous SET AUDITTRAIL command in this session, this parameter 
is optional in the ADD AUDITTRAIL command; otherwise, this parameter is 
required.
You must specify at least one volume; up to 16 are allowed. A single volume 
cannot be configured as an active volume for more than one audit trail. A volume 
configured as an active-audit volume cannot be configured as a data volume. To 
add more audit volumes to the configuration later, you can use the ALTER 
AUDITTRAIL command.
Volumes of the same size should be used for a specific audit trail. TMF allocates 
the same number of files on each volume, and all volumes must be able to hold all 
of those files. If a mixture of large and small disks is used for an audit trail, some 
space on the large disks will remain unused because this space will receive neither 
the active-audit trail nor the audited files. The unused space, however, could be 
configured as overflow space or audit restore space.
FILESPERVOLUME integer
specifies the number of files in the audit trail that reside on each active-audit 
volume configured. The audit trail’s capacity is determined by the number of audit- 
trail files per volume, the number of active-audit volumes, and the file sizes. TMF 
pre-allocates these files when the ADD AUDITTRAIL command is executed.  If 
TMF cannot allocate all the files, this command fails.
The minimum value for FILESPERVOLUME is 1 and the maximum is 100. The 
default is 5. 
To change the FILESPERVOLUME value later, you can use the ALTER 
AUDITTRAIL command.
OVERFLOWVOL[S]
specifies the volume used as overflow space for the audit trail. Although this 
attribute is not required by TMF, if you omit it, TMF issues a message at TMF 
startup, indicating that an overflow-audit volume should be configured.  
You can specify from 1 to 16 overflow-audit volumes. These can be the same 
volumes as the active-audit volumes; they can also be data volumes or any 
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 note about the preconfiguration of data volumes that appears 
under the discussion of the ADD DATAVOLS
 command.
Caution. The number of active-audit volumes multiplied by the value of FILESPERVOLUME 
must be 2 or more.
