When adding a volume to the pool for which Smart Pool is enabled, note the following:

Up to three different drives types/RPM are allowed between all the pool-VOLs to be added.

Volumes to be added to the same pool must have the same RAID level across all the same
drive type/RPM pool-VOLs.

For example, you cannot add a volume whose drive type/RPM is SAS/15k and whose RAID
level is 5 (3D+1P) when a volume whose drive type/RPM is also SAS/15k but whose RAID
level is 5 (7D+1P) is already in the pool

Up to three values are allowed for Drive Type/RPM for the volume.

If you increase the pool capacity by adding a pool-VOL, a portion of the existing data in the pool
automatically migrates from an older pool-VOL to the newly added pool-VOL, balancing the usage
levels of all the pool-VOLs. If you do not want to automate balancing of the usage levels of
pool-VOLs, call HP Technical Support for assistance.

Thin Provisioning does not automatically balance the usage levels among pool-VOLs if the cache
memory is not redundant or if the pool usage reaches up to the threshold.

The pool-VOLs contained in a pool can be added or deleted. Removing a pool-VOL does not delete
the pool or any related THP V-VOLs. You must delete all THP V-VOLs related to the pool before the
pool can be deleted. When the pool is deleted, all data in the pool is also deleted.

Pool status

The following table describes the pool status that appears in Remote Web Console. The status
indicates that a SIM code may have been issued that needs to be resolved. See

“SIM reference

codes” (page 148)

for SIM code details.

The THP V-VOL status remains normal even though the pool status may be something other than
normal.

SIM code*

Explanation

Status

None

Normal status.

Normal

If the pool-VOL is blocked, SIM code 627XXX
is reported.

A pool-VOL in the pool is blocked.

Warning

620XXX , 621XXX, or 626XXX

The pool usage level may exceed a pool threshold.

Exceeded
Threshold

None

The pools is being shrunk and the pool-VOLs are
being deleted.

Shrinking

622XXX or 623XXX

The pool is full or an error occurred in the pool,
therefore the pool is blocked.

Blocked

*XXX in the SIM code indicates the hexadecimal pool number.

Creating a pool

The following procedure tells how to create a pool using Remote Web Console. This procedure is
for setting up Thin Provisioning, but optional steps are shown for setting up Smart Tiers if you chose
to add tiers to your storage system.

Before creating a pool, you must install the proper amount of shared memory, and you must have
a V-VOL management area in shared memory. When shared memory is added, the V-VOL
management area is automatically created. To add shared memory, contact your HP representative.
