ALTER AUDITDUMP
Attributes that you do not specify remain unchanged. So, if you omit an optional
parameter, one of the following actions takes place:
•
If one or more previous TMFCOM commands (such as ALTER AUDITDUMP or
ADD AUDITTRAIL) specified the parameter, the value entered in the last of these
commands remains assigned. For example, if the last ALTER AUDITDUMP
command assigned the node \NYORK for the SYSTEM parameter, the current
ALTER AUDITDUMP command would use the node \NYORK.
•
If no previous TMFCOM command specified the parameter, the originally assigned
default remains assigned. For example, if no earlier ALTER AUDITDUMP
command specified the node in the SYSTEM parameter, the current ALTER
AUDITDUMP command would use the local node.
If you attempt any of the following actions, an error occurs:
•
Adding a disk media attribute that already exists.
•
Deleting a disk media attribute that is not currently configured.
•
Specifying the same disk media name for the same option (ADDDISKMEDIA or
DELDISKMEDIA) more than once in the same command. For example, you
cannot specify the same disk volume more than once in the ADDDISKMEDIA
attribute, nor more than once in the DELDISKMEDIA attribute. However, you can
use DELDISKMEDIA to delete a disk and then use ADDDISKMEDIA in the same
command to add that same disk back into the configuration; this capability allows
you, for example, to respecify the order in which disks are used.
If you specify ADDDISKMEDIA or DELDISKMEDIA, you must also specify MEDIUM
DISK.
If you specify MEDIUM DISK:
•
You cannot specify any attributes that apply to tape-based dumps, namely:
BLOCKSIZE, COPIES, SYSTEM, VERIFYTAPE, and UNLOAD.
•
There must be a minimum of 1 and a maximum of 16 ADDDISKMEDIA or
DELDISKMEDIA attributes configured when the command completes.
If the audit dump configuration was set to MEDIUM DISK and the ALTER AUDITDUMP
command specifies MEDIUM TAPE and is successful, all previously configured disk
media attributes are deleted from the configuration.
Specifying two copies of an audit dump is recommended for dumping to tape. By using
the SYSTEM (node, node) and COPIES 2 PARALLEL parameter constructs, you can
produce parallel dumps on two nodes (one dump per node). Both nodes can be
remote nodes, or one can be a remote node and the other your local node. All reels of
a specific copy (Copy 1 or Copy 2), however, must be made on the same node.
Specifying two nodes in the SYSTEM parameter produces the dump on parallel copies
of tapes, one copy per node. If TMF later tries to restore the dump, TMF always
requests the dump tape to be mounted on any available drive on the first node
specified in the SYSTEM parameter.
