When cabling the node, you must also cable the disk shelves, and switch. To cable the node, complete the following steps, using the illustration for reference.
Step
|
Action
|
|---|
|
1 |
Cable the first FC HBA to Bank 1 of Switch 1 and Switch 2. In the example, Port A of the FC HBA is cabled to Port 0 of Switch 1 and Port B is cabled to Port 0 of Switch 2.
|
|
2 |
Cable the second FC HBA to Port 1 on both switches, with Port A on Switch 1 and Port B on Switch 2.
|

Connect the Pool 0 disks to Bank 2, Pool 0 of the switches by completing the following steps:
- Connect the Input port of LRC/ESH A to port in Pool 0 in Bank
1 on Switch 2.
- Connect the Input port of LRC/ESH B to the port in Pool 0 Bank
1 on Switch 1. 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.
In the example, the Pool 0 disk shelves are connected to Switch Port 8 on both Switch 1 and 2.

Connect the Pool 1 disks to Bank 1, Pool 1 of the switches by completing the following steps:
- Connect the Input port of LRC/ESH A to port in Pool 1 in Bank
1 on Switch 2.
- Connect the Input port of LRC/ESH B to port in Pool 1 in Bank
1 on Switch 1. 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.
In the example, the disk shelves are connected to Switch Port 4 on both Switch 1 and 2.

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
ha15*> 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 one ISL cable to any port on each switch. In the example, Port 13 is used on both switches.
|
|
7 |
Connect the VI-MC cluster adapter to the switches, with Port 1 connecting to Switch 1 and Port 2 to Switch 2.
|
|
8 |
Check to make sure the node can see all disk shelves by entering the following command on the console:
vol status -r
Results
Both disk pools are displayed. If some disk shelves are not displayed, check the cabling on the disk shelf and the switch.
