Chapter 1 Quick SAN setup 21

Step 4: Set up the standby metadata controller

Now set up the standby metadata controller. This computer must have Mac OS X Lion

Server installed but not yet set up.

Set up the standby controller:

1 Turn on the computer you’re using as the standby metadata controller.

2 Follow the server setup assistant’s onscreen instructions to congure the computer,

paying special attention to the settings in the following panes:

Administrator Account: Enter the same account name and password that you used

on your client computers.

Time Zone: Congure the computer to use a network time server, which sets the date

and time automatically.

Xsan: Select “Congure as Xsan Metadata Controller or Client.”

Xsan Computer Type: Select “Congure as Standby Xsan Metadata Controller.”

Network: Enable only the public Ethernet port (Ethernet 1 at the top of the list).

Choose a conguration method from the pop-up menu and enter the appropriate

settings for the computer. You can choose:

Â Manually, and enter the static public IP address, subnet mask, router address, and

DNS server address for the computer

Â Using DHCP with manual address, and enter the computer’s IP address if your

DHCP server provides other TCP/IP connection settings

The standby metadata controller can now join the SAN and is detected by the primary

metadata controller during SAN setup.

Step 5: Set up the RAID systems

Now congure your RAID systems. Xsan sees the RAID arrays provided by the RAID

systems as Fibre Channel logical unit numbers (LUNs) that can be combined to create

SAN volumes.

Set up the RAID systems:

1 Follow the instructions that come with your RAID systems to turn them on and

congure their network, management, and security settings.

2 If your RAID systems come with RAID sets already congured, they’re detected

during SAN setup, and you can skip to “Step 6: Create a metadata array” on page 22;

otherwise, use the management software that comes with the RAID system to create

arrays that are the same size, leaving three drives on one system unassigned so you

can create a small, separate metadata LUN as described in the next step.

Setup scripts for Promise RAID systems are available at www.apple.com/support/xsan/.
