Figure 6-17   Creating a child pool
When the dialog window opens, enter the name and capacity of the child pool and click 
Create, as shown in Figure 6-18.
Figure 6-18   Defining a child pool
After the child pool is created, it is listed in the Pools pane under its parent pool. Toggle the 
sign to the left of the storage pool icon to either show or hide the child pools, as shown in 
Figure 6-19.
Figure 6-19   Listing parent and child pools
Creation of a child pool within a child pool is not possible.
In the CLI, the same mkmdiskgrp command that was used for parent pools is used to create 
child pools. You need to specify the parent pool for your new child pool and its size, as shown 
in Example 6-9. Size is given in MB and should be equal to parent’s pool extent size multiplied 
by an integer. In this case, it is 100 * 1024MB = 100 GB.
