324 Implementing an Open IBM SAN

LED on the SSA drive will flash and then it will move to the next drive. This

test should continue until all drives have been tested. The test runs in a

continuous cycle, so once all drives have been tested at least once, the

Router is powered off.

If a drive fails the test, the testing will stop, and the Router’s Status LED will

flash a diagnostic code. A code map with a description of the errors can be

found in the SLIC Router Installation and User’s Guide, 310-605759.

5. Assign Fibre Channel target.

With the Router powered off, you can now assign a Fibre Channel target ID

number to the Router. Any number can be selected, however, this number

must be a unique ID. No other device can have the same Fibre Channel target

ID once it is set on the Router.

This is done by setting selected dip switches in SW1 to the down position.

The switch is set up in binary notation: a switch that is down represents a 1

and a switch up represents a 0. Figure 5-2 shows the switch numbers and

their corresponding value.

Figure 5-2 SW1 dip switches

For example, by setting switch 2 and 0 down, a value of 5 is represented. All

other switches would be in the up position. By setting a switch down, its value

is added. To change a number that was previously set on a Router, power

must be cycled to the Router for the change to take effect.

6. Map the physical drives.

Before powering on again, SW2 must be set to mode 3 with switch 0 and 1

set down, and all other switches set up. The Router is powered on, the Status

LED will flash rapidly to rediscover the disks and the SSA drive LEDs should

be on solid. Once completed, the status LED will be solid, and the drives are

now considered to be mapped physical drives. The Router is powered off.
