Step 7: Upgrade the SAN clients

When your SAN controllers are all running Xsan 2.2, you can upgrade the SAN clients.

If you have any client computers with PowerPC processors, they can only be upgraded
to Xsan 2.1.1 and you won’t be able to enable extended attributes on your volumes.

Note: If you’re upgrading a client running Xsan 1.4.2, remove it from the SAN, install
Xsan 2.2 (Xsan 2.1.1 for a PowerPC client), and then add the client back to the SAN.

To upgrade Xsan only:
Choose Software Update from the Apple menu and install the Xsan 2.2 update.


If the client has a PowerPC processor, you can’t upgrade beyond Xsan 2.1.1.

To upgrade Mac OS X and Xsan:


Use Xsan Admin to remove the client from the SAN.


Install Mac OS X v10.6 or Mac OS X Server v10.6 on the client computer.

Mac OS X v10.6 runs only on computers with Intel processors.


Install Xsan 2.2 on the client.


Use Xsan Admin to add the client back to the SAN.

If Xsan Admin displays a message about “Incorrect Search Policy,” use System
Preferences > Accounts > Login Options (Mac OS X v10.6) or the Directory Utility
application (Mac OS X v10.5) to update the search policy.

There are underlying differences between Xsan 2.2 for Mac OS X v10.5 and Xsan 2.2 for
Mac OS X v10.6. If you install Xsan 2.2 on a computer running Mac OS X v10.5 and then
upgrade that computer to Mac OS X v10.6, use Software Update to update Xsan 2.2.
