Apple Xsan 2 - Manual (Page 112)

Make a standby controller the primary controller
Make a standby metadata controller the primary metadata controller:
1 In Xsan Admin, select Computers in the SAN Assets list.
2 Select the standby metadata controller you want to promote, and choose Make
Primary Controller from the Action pop-up menu.
Convert a controller to a client
If you no longer want a computer to act as a metadata controller for SAN volumes, you
can demote the controller to a SAN client.
Convert a metadata controller to a client:
In Xsan Admin, select Computers in the SAN Assets list, select the metadata controller
m
in the list, and choose Make Client from the Action pop-up menu (gear).
If you can’t choose Make Client, make sure all Xsan clients and metadata controllers
are turned on and their status is Ready in Xsan Admin’s Computers list.
You can’t demote the primary metadata controller if it’s managing users and groups.
Access controller computers remotely
Xsan Admin can help you connect to an Xsan metadata controller so you can observe
or control it over the network. Using Xsan Admin, you can:
Start a screen sharing session so you can observe or control another computer. Â
Open Terminal so you can log in using SSH and control another computer. Â
