6-2 SANRAD V-Switch CLI User Manual
Introduction to Volume Configuration
This chapter describes how to identify the SAN storage devices and use them to
create subdisks and virtual volumes. Each description includes:
ƒ A general description and generic diagram.
ƒ The basic command, switches and parameters needed to execute the
command.
ƒ An example of how to use the command with an accompanying
diagram.
The specific examples used in this chapter contain two JBODs; each JBOD
having four disks, each with a volume of 18 GB. See the example in Figure 6-1.
The Volume Manager names all disks automatically during the auto-discovery
process. For FC, this name includes FC disk’s World Wide Unique Identifier
(WWUI) serial number. For SCSI, this name includes the SCSI disk port number
and SCSI bus ID. This name is important in identifying disks for re-creating
volume hierarchies on both V-Switches in a cluster.

If you are working in a V-Switch cluster, you need to configure all subdisks and
volumes on both V-Switches in the V-Switch cluster. For more information on
V-Switch clusters, see Chapter 5 “
