How to Set Up Storage Partitioning
To set up storage partitioning:
1. LSI, CLARiiON, Sun 6130 and Sun 35xx only: Create a storage pool (sometimes referred to as
a volume group or RAID group). For more information about storage pools, see ”About Storage
Pools” on page 541
2. Create a volume. For more information about volumes, especially in CLARiiON storage systems,
see ”About Volumes” on page 541.
3. Create a host security group. For more information about host security groups, see ”About Host
Security Groups” on page 541.
About Storage Pools
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. LSI and CLARiiON storage systems
require that a storage pool be created and volumes be allocated from the storage pool. For more
information, see ”Creating a Storage Pool (LSI, CLARiiON, Sun 6130 and Sun 35xx)” on
page 543.
About Volumes
A volume is a virtual disk. Volumes are created in sizes that are desirable for being shown as a
LUN. A volume can be associated with more than one fibre channel port, creating multiple LUNs
corresponding to the same volume. (The defining characteristics of a LUN are the volume, port, and
LUN number.)
On CLARiiON storage systems a volume is owned by one of the storage processors. Creating a
volume also creates a LUN for this volume and for each port of the storage processor that owns the
volume. A LUN mapped to a port is visible to all the ports on that controller. Mapping a volume to
a port on a CLARiiON storage system also maps that volume to all ports that reside on the same
storage processor as the selected port. It also causes the volume to be unmapped from all the ports
of the other storage processor. Some storage systems have their volumes fully configured during
install. For these storage systems, Users can concatenate multiple volumes together to create a new
volume.
For more information, see ”Creating a Storage Volume” on page 547.
About Host Security Groups
Host security groups define which initiators (HBA ports) have access to specified storage volumes.
Host security groups are associated with a fibre-channel port and contain a list of HBA port initiators
and the volumes they can see.
For more information, see ”Creating Host Security Groups” on page 558 and ”Rules for Creating
Host Security Groups” on page 551.
