2 Create a volume.
A volume is a virtual disk. Volumes are created
in sizes that are desirable for being shown as a
LUN.
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 each port of the storage processor
that owns this volume. 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 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.

3 Create a Host Security Group. Host Security
Groups define which initiators (HBA ports) have
access to specified storage volumes. They are
associated with a fibre-channel port and contain
a list of HBA port initiators and the volumes they
can see.

page 368 and ”Rules for Creating Host
Security Groups” on page 363
