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:
A general description and generic diagram.
The basic command, switches and parameters needed to execute the command.
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 35.
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
