The remote switches need to be cabled so that they can work with the local switches.
To cable the remote switches, complete the following steps.
To cable the node, disk shelves, and switch, complete the following steps, using the illustration for reference.
Step
|
Action
|
|---|
|
1 |
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 3 and Port B is cabled to Port 8 of Switch 4.
|
|
2 |
Cable the second FC HBA to Port 9 on both switches, with Port A on Switch 3 and Port B on Switch 4.

Connect the Pool 0 disks to Bank 1, Pool 0 of the switches by completing the following steps:
- Connect the Input port of LRC/ESH A to the port in Pool 0 in
Bank 1 on Switch 3.
- Connect the Input port of LRC/ESH B to the 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.
- 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.
- Set the terminate switch on the last disk shelf in the loop to Off.
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:
- Connect the Input port of LRC/ESH A to the port in Pool 1 in
Bank 2 on Switch 3.
- Connect the Input port of LRC/ESH B to the 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.
- 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.
- Set the terminate switch on the last disk shelf in the loop to Off.
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 have dual paths 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
.

.
ha15sw:10.52 B ha16sw:10.52 A 6 4
|
|
6 |
Connect the ISL from Switch 1 to Switch 3 and the ISL from Switch 2 to Switch 4.
|
|
7 |
Connect the VI-MC cluster adapter to the switches, with Port 1 connecting to Switch 3 and Port 2 to Switch 4.
|
|
8 |
Boot the node.
|
|
9 |
Check to make sure that the node can see all disk shelves by entering the following command on the console:
vol status -r
|
|
10 |
Go to Step 5: Configuring the nodes.
