Changing a Controller’s IP Address
Follow these instructions if you need to change the IP address of an Xsan controller.
To change a controller’s IP address:
1 If you have a standby controller in the SAN, switch the active controller’s volumes to
the standby controller. For help, see “Switching to a Standby Controller” on page 65.
If you don’t want to switch the volumes to a standby controller, just stop them: in Xsan
Admin, select the volumes and click Stop Volume.
2 When all volumes are hosted by the standby controller (or stopped, if you don’t have a
standby controller), change the computer’s role to client.
In Xsan Admin, select the SAN, click Setup, and click Computers. Then double-click the
computer and change its role to Client.
3 Change the original controller’s IP address.
If the controller is running Mac OS X Server, you must also run the changeip command-
line tool. For more information, see the Mac OS X Server Command-Line Administration
guide at www.apple.com/server/documentation.
4 Restart the computer.
5 Reset the computer to act as a controller with its new IP address.
In Xsan Admin, select the SAN, click Setup, and click Computers. Double-click the
computer in the list and change its role to Controller.
6 Switch control of active volumes back to the primary controller. (If you stopped the
volumes because you have no standby controller, restart them.)
