Appendix A Upgrade to Xsan 2.3 133
10 Migrate remaining SAN clients.
11 Enable extended attributes.
12 Change filename case sensitivity.
13 Reenable Spotlight.
14 Recreate your MultiSAN configuration.
Step 1: Back up your SAN volumes
Before you begin, make a backup copy of the files on your SAN volumes.
Step 2: Disable Spotlight on all volumes
Disable Spotlight on all Xsan volumes during the migration to new SAN computers.
Disable Spotlight on all volumes:
1 In Xsan Admin, select Volumes in the SAN Assets list.
2 Select a volume and choose Edit Volume Settings from the Action pop-up menu (gear).
3 Click to deselect “Enable on this volume” next to Spotlight.
4 Repeat for all volumes in the SAN.
Step 3: Adjust volume failover priorities
If you use the MultiSAN capability of Xsan to host volumes on different subsets of the
available controllers, adjust volume failover priorities so that all volumes can fail over
to the primary metadata controller.
Make sure all volumes will fail over to the new controllers:
1 Open Xsan Admin and select Volumes in the SAN Assets list.
2 Select a volume and choose Edit Failover Priority from the Action pop-up menu (gear).
3 Click to select the primary metadata controller in the list, and click OK.
4 Repeat for all volumes in the SAN.
Step 4: Convert all standby controllers to clients
Identify the primary metadata controller, and then convert all other metadata
controllers to Xsan clients. If a metadata controller is hosting a volume when you
convert it to a client, another metadata controller begins hosting the volume. When
you finish this step, the primary metadata controller is hosting all SAN volumes.
Identify the 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.
Don’t convert that controller to a client.
