Restoring Files
Restoring from Multiple Devices (RESTORESET)
Enter the following RESTORE command to RESTORE files from a set of three sequential tape
devices:
:RESTORE ;@.@.@;RESTORESET=(*T,*T,*T)
You can RESTORE files that were created using parallel devices or parallel device pools in a
sequential configuration. For example, to RESTORE a set of reels that have been created
using parallel device pools, you must use the following logical order to mount the reels on
sequential devices: A1, A2....B1, B2 and so on. (The first alphabetic character, in capital
letters, indicates an original, unique parallel set; the second numeric character indicates
an original sequential reel within the set.) That is, mount A1 first, followed by A2. The reel
that you mount prior to B1 should be the last "A" reel.
NOTE Sequential RESTORE is not available for labeled tapes.
Parallel Devices
A parallel device or parallel device pool configuration can be used for restoring files.
Therefore, you can use the same designations with the RESTORESET parameter that you
can use with the STORESET parameter. Refer to Chapter 3, "Preparing Storage Devices," for
information on storing to multiple devices.
If you gave the tape devices a single filename such as:
:FILE T;DEV=TAPE
Enter the following RESTORE command to copy files from a set of two parallel tape devices:
:RESTORE;@.@.@;RESTORESET=(*T),(*T)
Describe parallel devices in the RESTORESET parameter by enclosing each back-referenced
device filename within parentheses. Use commas to separate devices.
To RESTORE files from parallel device pools, use parentheses to group the devices into pools.
Separate the devices in the pool from one another with commas. Commas also separate
each device pool.
For example, the following commands copy files from two parallel device pools. Each device
pool contains two sequential devices. In the following example, RESTORE uses a total of four
devices divided into two device pools.
:FILE PPA1;DEV=7
:FILE PPA2;DEV=8
:FILE PPB1;DEV=9
:FILE PPB2;DEV=11
:RESTORE ;@.OPERATOR.SYS;RESTORESET=(*PPA1,*PPA2),(*PPB1,*PPB2)
If you gave the tape devices a single filename such as:
:FILE T;DEV=TAPE
Enter the following RESTORE command to copy files from a set of parallel device pools:
:RESTORE ;@.@.@;RESTORESET=(*T,*T),(*T,*T)
