7Volume groups are not represented in the provisioning or properties of IBM DS type 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.

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.
