Preparing Storage Devices
Preparation Process
However, you may choose to employ multiple device configurations at times when you have
a large set of files to store and you want to speed up the process. If so, you probably want to
use the FILE command to give each device a filename that reminds you of its position.
Then use the STORESET parameter in a STORE command to reference the multiple devices.
For example, to store files to three sequential devices, use the following set of commands:
:FILE SEQ1;DEV=7
:FILE SEQ2;DEV=8
:FILE SEQ3;DEV=9
:STORE @.@.@;;STORESET=(*SEQ1,*SEQ2,*SEQ3)
The above STORE command copies all system and user files to three sequential devices. The
parentheses surrounding backreferenced file names group the devices into a device pool.
NOTE
You do not backreference the filename of a backup device immediately after
the name(s) of the file(s) you are storing when you use the STORESET
parameter. Rather, you must use a placeholder for the missing parameter
normally supplied when using a single backup device. The placeholder is
provided by the use of ;; in the STORE command.
If you gave the backup devices a single filename such as:
:FILE T;DEV=TAPE
enter the following STORE command to copy files to a set of four sequential backup devices:
:STORE @.@.@;;STORESET=(*T,*T,*T,*T)
To store files to a set of four parallel devices, you might use the following set of commands:
:FILE PARA;DEV=7
:FILE PARB;DEV=8
:FILE PARC;DEV=9
:FILE PARD;DEV=11
:STORE @.OPERATOR.SYS;;&
:STORESET=(*PARA),(*PARB),(*PARC),(*PARD)
If you gave the backup devices a single filename such as:
:FILE T;DEV=TAPE
enter the following STORE command to copy files to a set of four parallel backup devices:
:STORE @.@.@;;STORESET=(*T),(*T),(*T),(*T)
You describe parallel devices in the STORESET parameter by enclosing each backreferenced
device filename within parentheses. Use commas to separate devices.
To store files to 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 to two parallel device
pools. Each device pool contains two sequential devices.
