3 Open Xsan Admin, select Computers in the SAN Assets list, and then click the Add
button (+).
4 When the assistant opens, select the new controller computer in the computer list and
click Continue. If the computer doesn’t appear in the list, click Add Remote Computer

After you add a controller to the SAN, volumes that are mounted on all other controllers
are mounted automatically on the new controllers. Volumes that are mounted only
on some controllers aren’t mounted automatically on the new controller, but you can
mount those volumes manually by selecting Mounts in the SAN Assets list.
