Auto LUN

The requirements and restrictions for performing Auto LUN operations are:

• User types. If theusertypeofyouruserID is storage partition administrator, you cannot use Auto

LUN. For details on the limitations when using Performance Monitor logged in as a storage

partition administrator, see the HP StorageWorks XP24000 Performance Monitor User's Guide.

• Combina

tions of volumes. Thesourceand target volumesmustbe managed by the same storage

system.

(An external volume can be used for source or target volume.)

Also, a c

ombination of source and target volumes should satisfy the following conditions:

•The LDKC:CU:LDEV numbers of volumes take the value between 00:00:00 and 00:FE:FF or

between 01:00:00 and 01:FE:FF.

•The sou

rceand target volumeshavethe same emulationtypeand capacity.

• If the emulation type is not OPEN-V, both the source and target volumes are custom-sized

volume (CV), or both the volumes are normal volumes.

Specif

y the volumes that satisfy the conditions above as the source and target volumes. The source

and tar

get volumes must be speciﬁed by LDEV ID, not VOLSER or port/TID/LUN.

• Source volumes. The following volumes cannot be used as source volumes:

• Volumes set as command devices (reserved for use by the host).

•Volum

es which are in an abnormal or inaccessible condition (for example, pinned track,

fenced).

• Volumes used by the IBM 3990 Concurrent Copy (CC) host software function.

•Volu

mes which have HP StorageWorks XP Cache Residency Manager data or Cache

Resi

dency Manager for Mainframe data stored in cache.

• Volumes used by HP StorageWorks XP Continuous Access Journal Software or Universal

Replicator for Mainframe as a journal volume.

• Volumes which are reserved by a migration program other than Auto LUN.

•Vol

umes on which RAID Manager is performing volume migration operation.

• Volumes that form an HP StorageWorks XP Snapshot pair.

• Virtual volumes and pool volumes that are used by XP Snapshot.

•Vi

rtual volumes and pool volumes that are used by HP StorageWorks XP Thin Provisioning.

• Volumes being shredded.
