Appendix A Upgrade to Xsan 2.3 135
3 Restart the old primary metadata controller in target disk mode, so the server setup
assistant can transfer data from it to a new server.
You can restart in target disk mode by holding down the T key when the computer
starts up.
4 Turn on the new server that you want to become the primary metadata controller, and
wait for the server setup assistant’s Welcome pane to appear.
5 Proceed through the server setup assistant to the "Transfer an Existing Mac Server”
pane, select “Transfer the information from an existing server,” and click Continue.
6 Connect the old primary metadata controller to the new server with a FireWire cable,
and when you’re ready to begin transferring data, click Continue in the Transfer Your
Mac Server pane.
7 After the server setup assistant finishes transferring data, proceed through the
remaining setup panes.
8 Shut down the old primary metadata controller, and disconnect it from the Ethernet
and Fibre Channel networks.
Don’t start up the old primary metadata controller while it’s connected to the Ethernet
networks, because it has the same IP address as the new server you migrated it to.
Step 8: Migrate former standby controllers
Use the server setup assistant to migrate server data from the former standby
metadata controllers, which you converted to SAN clients in an earlier step, to new
servers. You convert the new servers to metadata controllers in the next step.
Migrate a former standby controller to a new server:
1 Make sure Xsan Admin isn’t open on any computer that can connect to a metadata
controller.
Xsan Admin can become confused if it’s open when a SAN computer’s IP address
migrates to a new computer.
2 Restart the former standby metadata controller in target disk mode, so the server
setup assistant can transfer data from it to a new server.
You can restart in target disk mode by holding down the T key when the computer
starts up.
3 Turn on the new server that you want to become the primary metadata controller, and
wait for the server setup assistant’s Welcome pane to appear.
4 Proceed through the server setup assistant to the "Transfer an Existing Mac Server”
pane, select “Transfer the information from an existing server,” and click Continue.
5 Connect the former standby metadata controller to the new server with a FireWire
cable, and when you’re ready to begin transferring data, click Continue in the Transfer
Your Mac Server pane.
