DUMP FILES
When the disk resides on a home (local) node:
•
The node name and the prefix are optional.
•
If the node name is not specified, the node on which your TMFSERVE is
running is assigned.
•
You can specify any value for the prefix.
•
If the prefix is not specified, the local-node default, ZT, is automatically
assigned as the prefix.
Optical discs are not supported for dump-to-disk operations.
If you specify ZTMF-TKN-DISKMEDIA, you must not specify the following fields:
ZBLOCKSIZE, ZCOPIES, ZSYSTEMNAME, TAPEMEDIA, and ZVERIFYTAPE.
ZTMF-TKN-EXTFILENAME
specifies the file at which the online dump begins. You can specify a wild card (*)
in the file-name or subvolume fields, but not in the volume field.
If you specify an asterisk in the file-name field, the dump starts at the beginning of
the subvolume. If you specify an asterisk in the subvolume field, the dump starts at
the beginning of the volume. To avoid dumping the entire database, you should
specify a fully qualified file name.
If you omit this field, TMF dumps the entire file set.
ZTMF-MAP-DUMP-FILES
is an extensible structured token specifying the attributes of the dumps to be
copied. This token is required; only one occurrence is allowed. This token
contains the following fields:
ZCOPIES
for dumps to tape, specifies the number of parallel copies made of each online
dump. Valid values are 1 or 2; the default is 1.
If you specify a value of 1, only one tape drive is required and the copy is
directed to that drive. If you specify a value of 2, two tape drives are required
and the copies are always produced in parallel, not serial, order.
A value of 2 is recommended in case one tape cannot be read because of a
tape media failure, or if each copy of the dump requires multiple tape volumes.
