Item Requirement
Pool limit per storage system 128
Pool IDs are assigned from 0 to 127.
This can include THP (including Smart and Real Time Smart Tier),
THP MF (including Smart MF and Real Time Smart Tier for
Mainframe), and FS pool types.
Increasing capacity Dynamically increase the pool-VOL capacity. To do this, increase
the capacity for at least one parity group.
Decreasing pool capacity Use the following workflow to decrease pool capacity:
1. Delete the pool-VOLs (see Decreasing pool capacity on page
159).
2. Reconfigure the pool (see Creating Fast Snap data pools on
page 89).
Deleting pools The pool is not used by an FS pair.
For more information about deleting pools, see Deleting pools on
page 170.
Data pool warning threshold Value: Warning Threshold
Range: 20 - 95%, in 1% increments.
Default: 80%
Note: If you exceed the data pool warning threshold, a warning is
issued through a service information message (SIM) and an SNMP
trap reporting excessive pool usage.
For more information:
• About editing the data pool warning threshold, see Editing the
data pool warning threshold on page 163.
• About checking alerts and checking the details of a SIM, see
