Apple Xsan 1.1 - Manual (Page 82)

82 Chapter 5 Managing Metadata Controllers
Adding a Controller
You can add one or more standby controllers to a SAN so that volumes are still
available if the primary controller fails.
Any computer set to act as a controller can also function as a client. So, if you don’t
want to dedicate a computer to act solely as a standby controller, you can use an
existing client.
To add a controller:
1 If you haven’t already, connect the new controller computer to the SAN’s Fibre Channel
and Ethernet networks and install the Xsan software.
2 In Xsan Admin, select the SAN in the SAN Components list and click Setup.
3 Select the new controller in the computer list and click Edit.
4 Choose Controller from the Role pop-up menu.
5 Choose a failover priority and click OK.
6 Choose the Ethernet interface the controller will use to communicate with other
devices on the SAN.
7 Type an Xsan software serial number.
You can find the serial number for a single copy of Xsan on the Xsan installer disc
sleeve. If you have purchased a site-licensed serial number, look on the paperwork you
received when you purchased the license.
