Apple Xsan 2 (Third Edition) - Manual (Page 8)

8 Upgrading to Xsan 2.2
To identify your Open Directory primary controller:
If you’re using Xsan Admin to manage users and groups, open Xsan Admin, select
m
Overview in the SAN Assets list, and look for the controller that has the user icon next
to its name. Upgrade that controller first.
To upgrade the controller to Mac OS X Server v10.6:
Insert the version 10.6
m Mac OS X Server Install Disc in the computer and double-click
Install Mac OS X.
Step 4: Upgrade the same controller to Xsan 2.2
Install the Xsan 2.2 update on the controller.
To update to Xsan 2.2:
Choose Software Update from the Apple menu and install the two Xsan 2.2 updates,
m
one for the file system and one for Xsan Admin.
If the computer is on a private network, you can use a computer that is connected to
the Internet to download the updates from www.apple.com/support/downloads, then
transfer the installers to the SAN computer and run them.
From this point forward, use only the Xsan 2.2 version of Xsan Admin.
Step 5: Upgrade the remaining controllers
Repeat steps 3 and 4 on each additional controller on the SAN. When all of your
controllers are running Xsan 2.2 (and optionally, Mac OS X Server v10.6), continue with
the next step.
Step 6: Reestablish Open Directory replicas
If you don’t use Xsan Admin to manage your SAN users and groups, or if no SAN
computers are running Mac OS X v10.6, skip to the next step. If your controllers are
running Mac OS X Server v10.6 and you do use Xsan Admin to manage your SAN
users and groups, you now have an Open Directory master on your primary controller
(the first controller you upgraded in steps 3 and 4). However, you need to reestablish
replicas of that directory on your other controllers.
To recreate the directory replicas:
Open Xsan Admin on one of your controllers and select Computers in the SAN Assets
m
list. A dialog prompts you to recreate the replicas.
If you’re not asked to replicate the directory, check to see if you have upgraded all
controllers in the SAN to Xsan 2.2, and then try again. If the replication prompt still
doesn’t appear, you can select a controller in the Computers pane in Xsan Admin
and choose Make Open Directory Replica from the Action (gear) pop-up menu.
