Command Definitions SP-Z
STORE
STORESET Specifies parallel and sequential backup devices. This option cannot be
used if the storefile parameter is specified, and it cannot be used in
conjunction with the TRANSPORT option.
Sequential tapes are specified in this way
;STORESET = (*tape1,*tape2,*tape3,...)
This instructs STORE to use only one drive at a time from the specified
serial pool for the store operation. It will select *tape1 first. When the first
reel of tape is exhausted, STORE will shift to the next drive specified
(*tape2), leaving the first free for rewinding and changing reels. Thus, at
any given time, only one drive is occupied with the store process. The effect
is to accelerate the process by eliminating the wait for a rewind and reel
switch to occur. When STORE has written to the last device specified, it will
wrap around to the first device.
To specify parallel devices, enter:
;STORESET=(*tape1),(*tape2),(*tape3) . . .
In this example, all three tapes will be used in parallel during the Store.
You can also specify that a set of tapes be stored in parallel. In the
following example, two tapes would be storing at any particular moment,
while the other two are rewinding, which permits the operator to switch
reels.
;STORESET=(*tape1,*tape2),(*tape3,*tape4)
device Specifies the device on which the file is to be stored. It must be magnetic
tape or DDS. This device should be specified in a file equation before you
invoke the STORE command, for example:
FILE DEVICE;DEV=TAPE
This file equation can also specify a remote device. If you are using the
TurboSTORE/iX 7X24 True-Online Backup product, then a disk file can
also be specified here. However, disk files can only be used with parallel
STORE sets, not serial STORE sets.
STORESET cannot be used in conjunction with TRANSPORT.
THE FOLLOWING OPTIONS ARE AVAILABLE ONLY IF TURBOSTORE XL OR
TURBOSTORE XL II IS INSTALLED ON YOUR SYSTEM. TURBOSTORE IS NOT PART
OF THE FUNDAMENTAL OPERATING SYSTEM, BUT MAY BE PURCHASED
SEPARATELY.
For additional information on TURBOSTORE XL, refer to the STORE and
TurboSTORE/iX Manual (30319-90001).
COMPRESS Specifies that host data compression is to be used during the store
operation. Currently, two levels of data compression are supported in
backup. If you do not specify a level, the default is HIGH.
