|
||
|
|
<div><p>Pools have two sets of numbering schemes: one is used within a
|
||
|
|
subsystem and one is system-wide. The subsystem uses a set of numbers that
|
||
|
|
refer to the pools it uses. Thus, when you create or change a subsystem description
|
||
|
|
you can define one or more pools and label them 1, 2, 3, and so on. These
|
||
|
|
are the designations of the subsystem pools, and they do not correspond to
|
||
|
|
the pool numbers shown on the Work with System Status (<span class="cmdname">WRKSYSSTS</span>)
|
||
|
|
display.</p>
|
||
|
|
<p>A different set of numbers is used to keep track of all pools on the system.
|
||
|
|
The Work with Subsystems (<span class="cmdname">WRKSBS</span>) display relates the subsystem
|
||
|
|
pool identifiers and the column headings to the system pool identifiers.</p>
