Apple Xsan 2 (Third Edition) - Manual (Page 6)

6 Upgrading to Xsan 2.2
Intel or PowerPC Processors?
To run Xsan 2.2, your metadata controllers must be Intel-based Xserve or Mac Pro
systems. You can have client computers with PowerPC processors, but they must run
Xsan 2.1.1. You can’t enable extended attributes on a volume that has Xsan 2.1.1 clients.
Which Procedure?
This migration guide contains two sets of instructions:
Follow “ Â Upgrading Your SAN Software” if you already have Intel-based metadata
controllers and you want to update Xsan to version 2.2 and, optionally, update
Mac OS X on your SAN computers to version 10.6.
Follow “
 Upgrading Both SAN Hardware and Software” if you need to replace your
current PowerPC-based controllers with Intel-based computers in addition to
updating the Xsan and Mac OS X software.
Problems with Xsan Admin?
If the Xsan 2.2 version of Xsan Admin quits unexpectedly during the migration process,
reopen it and continue. This can happen while you’re temporarily working with
different versions of Xsan during the migration. Your SAN’s configuration and volume
data are not affected.
