Apple Xsan 2 - Manual (Page 127)

127
This appendix shows you how to upgrade your Xsan 2 SAN
to Xsan 2.3.
Follow the instructions in this appendix to upgrade an existing Xsan 2 SAN and its
volumes to Xsan 2.3. Upgraded metadata controllers must have Mac OS X Lion Server.
Upgraded SAN clients must have Mac OS X Lion or Lion Server, which include Xsan 2.3,
or Mac OS X or Mac OS X Server v10.6 with Xsan 2.2.1 or later installed.
Before you begin
Review the following information before you upgrade your SAN.
If you’re not running Xsan 2.0 or later
This appendix shows you how to upgrade from Xsan 2.0 or later. For help upgrading
from an earlier version of Xsan, see the Xsan 2 Migration Guide, Second Edition, available
at www.apple.com/xsan/resources/.
Lion or Lion Server?
The Xsan file system is included with Mac OS X Lion and Lion Server. The Xsan Admin
app is included with Mac OS X Lion Server. Unless otherwise indicated, a statement
in this appendix about Mac OS X Lion also applies to Mac OS X Lion Server. However,
if you use Xsan Admin to manage SAN users and groups, you must have Mac OS X Lion
Server on your metadata controllers to create the Open Directory master and its replicas.
Which procedure?
This appendix contains two sets of instructions:
Follow “ Â Upgrade your SAN software” below if you want to upgrade your current
metadata controllers to Xsan version 2.3 and Mac OS X Lion Server.
Follow “
 Upgrade SAN hardware and software” on page 132 if you need to replace
your current metadata controllers with Intel-based computers in addition to
upgrading to Xsan 2.3 and Mac OS X Lion Server.
