Follow step by step instructions for setting up a shared
volume on an Xsan SAN.
This chapter explains how to connect SAN networks, prepare RAID arrays (LUNs), use
the Xsan Admin app, set up a SAN, and create a shared volume. This chapter also tells
you how to administer Xsan remotely, rename a SAN, remove a SAN, set up additional
SANs, and manage multiple SANs.
Connect computers and storage devices
Before you open Xsan Admin to configure your SAN, you must connect client
computers, controller computers, and storage devices to the SAN’s Fibre Channel
and Ethernet networks. In addition, make sure your networks meet the requirements
summarized in “Fibre Channel fabric” on page 41 and “Ethernet TCP/IP network” on
page 42.
Prepare LUNs
New RAID systems often come configured as one or more RAID arrays. So, out of the
box, your RAID system might provide LUNs that you can use for most SAN applications.
For details, see the documentation for your RAID system. Unless you have well-defined,
special needs, no other LUN preparation is needed.
To set up other combinations of RAID arrays or slices, use the management software
that comes with your RAID systems to create the arrays before you add the resulting
LUNs to your SAN’s storage pools. For information about choosing a RAID scheme, see
“Choose RAID schemes for LUNs” on page 47.
Note: Don’t use Disk Utility to format arrays or slices for use with Xsan. LUNs are
labeled and initialized when you add them to a storage pool using Xsan Admin. After
they are labeled, the LUNs can’t be modified using Disk Utility.
