1
Creating volume means marking existing device as accessible to HSG management, deleting
volume means returning device to free device pool.
2
Solutions Enabler 5.0 or later is required.
3
Volumes created on IBM storage systems cannot be deleted.
4
RAID level can be specified for first volume in a pool, subsequent volumes inherit this setting
5
The “Create Volume Using Settings” column refers to the provisioning capability on the
management server that lets you create different kinds of volumes from a pool depending on
whether you want it optimized, such as for streaming, random access or high availability.
6
Unlike the native tool for the Sun 6130 storage system, the management server refers to virtual
disks as storage pools.
7
Volume groups are not represented in the provisioning or properties of IBM storage systems.
The HSGs are based on a host connection, which does not give any indication as to which
volume groups each of them belongs. Volume group can have many host connections, but only
one host connection can be part of a volume group.
See the following topics for more information about how storage provisioning works on your
storage system.

The following table provides an overview of the required steps for setting up storage partitioning.

1 (Engenio, CLARiiON, Sun 6130 and Sun 35xx)
Create a storage pool. Sometimes referred to as
a volume group or RAID group.
A storage pool is a group of disks associated
together through a RAID configuration. The
pool’s capabilities define the level of protection
for the associated volumes and LUNs.
EMC Symmetrix and HDS storage systems have
storage pools that are predefined. Engenio and
CLARiiON storage systems require a storage
pool to be created and volumes to be allocated
from a storage pool.

CLARiiON, Sun 6130 and Sun 35xx)”
