Actions on child storage pools
You can Rename, Resize, and Delete child pool. Also, it is possible to modify the warning 
threshold for it and edit the pool throttle. To select an action, right-click the child storage pool, 
as shown in Figure 6-20. Alternatively, select the storage pool and click Actions.
Figure 6-20   Actions on child pools
Select Resize to increase or decrease the capacity of the child storage pool, as shown in 
Figure 6-21. Enter the new pool capacity and click Resize.
Figure 6-21   Resizing a child pool
When the child pool is shrunk, the system resets the warning threshold and issues a warning 
if the threshold is reached.
To rename and resize child pool, use chmdiskgrp. Example 6-10 on page 206 renames child 
pool Pool0_child0 to Pool0_child_new and reduces its size to 44 GB. If successful, the 
command returns no feedback.
Note: You cannot shrink a child pool below its real capacity. Thus, the new size of a child 
pool needs to be larger than the capacity used by its volumes.
