Create a volume.

”Creating a Storage Volume” on

 

A volume is a virtual disk. Volumes are created

page 324

 

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

”Creating Host Security Groups” on

 

Groups define which initiators (HBA ports)

page 334 and ”Rules for Creating

 

have access to specified storage volumes. They

Host Security Groups” on page 329

 

are associated with a fibre-channel port and

 

 

contain a list of HBA port initiators and the

 

 

volumes they can see.
