Step 4: Cabling the remote switches and node

Log into Switch 3 and set it up as described in Step 2: Configuring the local switches.

Repeat Step 1 for Switch 4.

Cable the first FC HBA to Bank 2 of Switch 3 and Switch 4. In the example, Port A of the FC HBA is cabled to Port 8 of Switch 1 and Port B is cabled to Port 8 of Switch 4.

Cable the second FC HBA to Port 9 on both switches, with Port A on Switch 4 and Port B on Switch 4.

Connect the Pool 0 disks to Bank 1, Pool 0 of the switches by completing the following steps:

1. Connect the Input port of LRC/ESH A to port in Pool 0 in Bank 1 on Switch 3.
2. Connect the Input port of LRC/ESH B to port in Pool 0 in Bank 1 on Switch 4. This must be the same port number you used for the LRC/ESH A cabling.
3. Connect the first disk shelf to the next disk shelf in the loop by connecting the Output port of the LRC/ESH of the first shelf to the corresponding Input Port of the next disk shelf's LRC/ESH.

In the example, the Pool 0 disk shelves are connected to Switch Port 0 on both Switch 3 and 4.

Connect the Pool 1 disks to Bank 2, Pool 1 of the switches by completing the following steps:

1. Connect the Input port of LRC/ESH A to port in Pool 1 in Bank 2 on Switch 3.
2. Connect the Input port of LRC/ESH B to port in Pool 1 in Bank 2 on Switch 4. This must be the same port number you used for the LRC/ESH A cabling.
3. Connect the first disk shelf to the next disk shelf in the loop by connecting the Output port of the LRC/ESH of the first shelf to the corresponding Input Port of the next disk shelf's LRC/ESH.

In the example, the Pool 1 disk shelves are connected to Switch Port 12 on both Switch 3 and 4.

Confirm that the disks are visible and dual pathed by entering the following command on the console:

storage show disk -p

Results

The output shows the disks connected to the switches, to what port they are connected, and to what disk and to which LRC/ESH they belong, as shown in the following example:

Example

ha16*> storage show disk -p

PRIMARY      PORT    SECONDARY    PORT    SHELF    BAY

------     ----    --------    ----   ----    --

ha15sw:2.40   A     ha16sw:2.40     B        5     0 

ha16sw:2.41   B     ha15sw:2.41     A        5     1

Connect the ISL from Switch 1 to Switch 3 and the ISL from Switch 2 to Switch 4.

Connect the VI-MC cluster adapter to the switches, with Port 1 connecting to Switch 3 and Port 2 to Switch 4.

Check to make sure the node can see all disk shelves by entering the following command on the console:

vol status -r

Connect the VI-MC cluster adapter to the switches, with Port 1 connecting to Switch 3 and Port 2 to Switch 4.

Go to Step 5: Configuring the nodes.
