Chapter 2 Setting Up a Storage Area Network 55
Step 4: Set Up LUNs
m New Xserve RAID systems are usually preconfigured as two RAID 5 arrays that are ready
to use as LUNs.To set up some other configuration of LUNs, use the RAID Admin
application to create RAID arrays or slices on your Xserve RAID systems. For help
choosing other RAID schemes, see “Choosing RAID Schemes for LUNs” on page 44.
Important: If you set up a LUN that is larger than 2 terabytes (TB), be aware that older
clients (those running Xsan on Mac OS X 10.3 Panther or Xsan 1.2 or earlier on
Mac OS X 10.4 Tiger) cannot read these large LUNs. A dialog appears on these older
clients that says the LUN is unreadable. Be sure to click Ignore to dismiss this dialog.
Do not click Format, or information on the corresponding Xsan volume will be lost. If
you use LUNs greater than 2 TB, you should upgrade all SAN clients to Xsan 1.3 or later
on Mac OS X or Mac OS X Server v10.4.
Step 5: Install Xsan Software on Clients and Controllers
Take the Xsan installation disc to each controller and client computer connected to the
SAN and install the Xsan software.
To install the Xsan file system and Xsan Admin application:
m Insert the disc and double-click the Xsan installer icon.
To install just the Xsan file system without Xsan Admin:
m Click Customize on the final installer window and deselect Xsan Admin.
To install just the Xsan Admin application:
m On the Xsan installation disc, open the Admin Tools folder, and double-click
XsanAdmin.pkg.
