operations. So if you want to create a LUSE volume and then perform LUN creation on the HDS box, it is a two-step process. First, use the management server to create LUSE volumes. Then create a LUN and map a volume to a target port, by creating a host security group. For more information, see ”Creating Host Security Groups” on page 558 and ”Rules for Creating Host Security Groups” on page 551.

HDS ships some of its storage systems with volumes already created. When the software first discovers an HDS storage system, it detects the volumes created by HDS. When you use the software's “create a volume” feature, you are assigning the already-created volume. For more information, see ”About Provisioning on HDS Storage Systems” on page 566.

LUSE made up of volumes from different RAID levels are not supported. You cannot use this product to provision this type of LUSE. Existing LUSE of this type may be incorrectly reported.

It is not possible to extend LUSEs using the management server software. You must perform this operation using the native tools.

NOTE: In a Hitachi Freedom Storage™ Thunder 9500™ V Series storage system, it is not possible to create a LUSE from a group of RAID-0 LDEVs.

For LSI Storage Systems

Make sure you select a volume group that can accommodate the requested size for the new volume. You can create volumes from existing free extent areas within a volume group.

No volume-to-LUN masking is done by default, except for CLARiiON storage systems. For more information, see ”Creating Host Security Groups” on page 558 and ”Rules for Creating Host Security Groups” on page 551.
