Step 3: Cabling the local node

Cabling the local node and disks  Top

To cable the node, complete the following steps, using the illustration for reference.

Note
You can only cable a maximum of two disk shelves per loop.

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.

3

Connect the Pool 0 disks to Bank 2, Pool 0 of the switches by completing the following steps:

  1. Connect the Input port of LRC/ESH A to the port in Pool 0 in Bank 1 on Switch 2.
  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.
  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.
  4. 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 8 on both Switch 1 and 2.

4

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

  1. Connect the Input port of LRC/ESH A to the port in Pool 1 in Bank 1 on Switch 2.
  2. Connect the Input port of LRC/ESH B to the 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.
  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.
  4. Set the terminate switch on the last disk shelf in the loop to Off.

In the example, the disk shelves are connected to Switch Port 4 on both Switch 1 and 2.

5

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

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

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

Result

All disks are displayed.

10

Go to the remote site and follow the instructions in Step 4: Cabling the remote switches and node.
