Step 3: Cabling the local node

Cable the first Fibre Channel HBA in slot 5 of the local node, to Switch 1 and Switch 2. In the example, Port A of the Fibre Channel HBA is cabled to Port 0 of Switch 1 and Port B is cabled to Port 0 of Switch 2.

Cable the second Fibre Channel HBA in slot 8 of the local node, to Port 1 on both switches, with Port A on Switch 1 and Port B on Switch 2.

Connect the local node Pool 0 disks to the switches by completing the following steps:

Note
In the example, the Pool 0 disk shelves are connected to switch port 9 on both Switch 1 and 2. However, any open set of switch ports in this quadrant can be used (limited to ports 8-11 in this configuration).

1. Connect the Input port of the LRC, ESH, or ESH2 channel A on disk shelf 1 to port 9 on Switch 2.
2. Connect the Input port of LRC, ESH, or ESH2 B on disk shelf 1 to port 9 on Switch 1.
3. Connect disk shelf 1 to disk shelf 2 by connecting the Output ports of the LRC, ESH, or ESH2 of disk shelf 1 to the Input ports of the corresponding LRC, ESH, or ESH2 modules of the next disk shelf.
4. Set the terminate switch on the last disk shelf in the loop to On, and set the switch to Off for all other disk shelves in the loop.

Connect the remote node Pool 1 disks to the switches by completing the following steps:

Note
In the example, the Pool 1 disk shelves are connected to switch port 5 on both Switch 1 and 2. However, any open set of switch ports in this quadrant can be used (limited to ports 4-7 in this configuration).

1. Connect the Input port of LRC, ESH, or ESH2 LRC, ESH, or ESH2LRC, ESH, or ESH2A on disk shelf 3 to port 5 on Switch 2.
2. Connect the Input port of B on disk shelf 3 to port 5 on Switch 1.
3. Connect disk shelf 3 to disk shelf 4 by connecting the Output ports of the LRC, ESH, or ESH2 of disk shelf 3 to the Input ports of the corresponding LRC, ESH, or ESH2 modules of the next disk shelf.
4. Set the terminate switch on the last disk shelf in the loop to On, and set the switch to Off for all other disk shelves in the loop.

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, or ESH2 they belong, as shown in the following example:

Example

ha15*> storage show disk -p

PRIMARY       PORT   SECONDARY      PORT   SHELF  BAY

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

switch1:4.40   A     switch2:4.40     B     5      0

switch2:4.41   B     switch1:4.41     A     5      1

.

.

.

switch1:8.52   B     switch2:8.52     A     6      4

Connect one ISL cable to any port on each switch, making sure that the ports have the same number. In the example, Port 13 is used on both switches.

Connect the VI-MC cluster adapter to the switches, with the top port connecting to Switch 1 and the bottom port to Switch 2.

Note
There should be one VI-MC cluster adapter connection per switch. The switch port connections do not have to be identical. In the example, the VI-MC cluster adapter connects to switch ports 7 and 12, but you can use any available switch ports.

Boot the node.

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.

Go to the remote site and follow the instructions in Step 4: Cabling the switches and nodes at the partner site.
