One method you will use to monitor pool capacity is setting thresholds. Once a threshold is exceeded, a

SIM (Service Information Message) is issued, and a trap is reported to SNMP. For more information about

SNMP traps, see HP StorageWorks XP24000 SNMP Agent Reference Guide.

You can monitor pool capacity directly by using the XP Thin Provisioning window (see

“XP Thin Provisioning Window” on page 38. For details about monitoring and tuning resources, see

“Monitoring and Tuning Resources”onpage21.

You can also monitor system performance using HP StorageWorks XP Performance Monitor or monitor

pool capacity using HP StorageWorks XP RAID Manager. For more information on Performance Monitor,

see HP StorageWorks XP24000 Performance Monitor User’s Guide. For more informationonRAID

Manager, see HP StorageWorks XP RAID Manager User's Guide.

Increasing

the Pool Capacity

You can incr

ease the pool capacity by adding a pool-VOL to the pool created for XP Thin Provisioning.

The total ca

pacity of pool-VOLs in a pool is the pool capacity. You need to check the free space on a

pool that can be used, and increase the pool, if necessary.

Deleting V-VOLs

When you delete V-VOLs created for XP Thin Provisioning, you need to execute the following procedure.

If you delete V-VOLs, the pool area that has been used by the V-VOLs until then is released and free

space on the pool is increased.

1. Delete the path deﬁnitions. For details on deleting path deﬁnitions, see the HP StorageWorks

XP24000 LUN Manager User’s Guide.

2. Perform LDEV formatting on the V-VOLs to delete them.

3. Release the association between the V-VOLs and pools.
