Upgrading to Xsan 1.4 on
Mac OS X version 10.4
Follow the instructions in this chapter if you are currently
using Xsan 1.1, 1.2, or 1.3 on Mac OS X version 10.3 or
Mac OS X version 10.4.
Note: If you are still running Xsan 1.0 or 1.0.1, you can follow the instructions in the
appendix to move to Xsan 1.1 on Mac OS X v10.4, and then follow the steps in this
chapter to complete the upgrade.
The following steps summarize how to upgrade your SAN to Xsan 1.4 if your controllers
are running Xsan 1.1 or later.
1 If needed, upgrade your controllers to Mac OS X v10.4.7.
2 If needed, migrate Xsan on your controllers to the equivalent Tiger version.
3 If needed, upgrade controllers and clients one version at a time to Xsan 1.3.
4 Upgrade your controllers to Xsan 1.4.
5 Upgrade the Xsan Admin application on administrator computers.
6 Optionally, return control of volumes to specific controllers.
7 Optionally, upgrade client computers to Mac OS X v10.4.7 and Xsan 1.4.
Instructions for each of these steps appear on the following pages.
Warning: Do not make any changes to Xsan settings (using either Xsan Admin or the
command-line tools) while you are upgrading your SAN controllers. If you need to
make configuration changes, wait until you finish upgrading all of your controllers.
