Apple Xsan 2 (Third Edition) - Manual (Page 12)

12 Upgrading to Xsan 2.2
To add a new controller:
1 Open Xsan Admin (the new 2.2 version) on either of the new controllers or on an
admin computer and follow the instructions in the SAN Assistant to connect to the
existing SAN.
2 When the Xsan Admin window appears, select Computers in the SAN Assets list.
3 Click the Add (+) button.
To promote an existing Intel-based client:
1 Open Xsan Admin (the new 2.2 version) and select Computers from the SAN Assets list.
2 Select the Intel-based client and choose Make Controller from the Action (gear) pop-
up menu.
Don’t be concerned if a message appears stating that an Open Directory replica can’t
be created on a computer running a different version of Mac OS X Server. You remove
older controllers in a later step.
Step 7: Adjust volume failover priorities
If you use the MultiSAN capability of Xsan to host volumes on different subsets of the
available controllers, you need to adjust volume failover priorities so that all volumes
are hosted by the new controllers during migration.
To make sure all volumes will fail over to the new controllers:
1 Open Xsan Admin (v2.2) and select Volumes in the SAN Assets list.
2 Select a volume and choose Edit Failover Priority from the Action (gear) pop-up menu.
3 Click to select each of the new controllers in the list, and click OK.
4 Repeat for all volumes in the SAN.
Step 8: Make an Intel-based controller the primary controller
If you use Xsan Admin to manage SAN users and groups, one of your old controllers
is hosting the SAN’s Open Directory master. Before you remove that controller from
the SAN, you need to make one of the new Intel-based controllers the new primary
controller.
To specify the primary controller:
1 Open Xsan Admin (v2.2) on one of the new controllers and select Computers in the
SAN Assets list.
2 Select one of the new Intel-based controllers and choose Make Primary Controller
from the Action (gear) pop-up menu.
3 If a client displays a message about “Incorrect Search Policy,” use the Directory Utility
application on the client to delete the old primary controller from its search policy.
