Step 4: Cabling the switches and nodes at the partner site

About partner site switch cabling  Top

You need to cable the switches at the partner site so that they can work with the local switches.

Cabling switches at the partner site  Top

To cable the partner site switches, complete the following steps.

Step

Action

1

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

2

Repeat Step 1 for Switch 4.

Cabling the remote node and disk shelves at the partner site  Top

To cable the remote node, disk shelves, and switch, complete the following steps, using the appropriate illustration for reference.

Step

Action

1

Cable the first Fibre Channel HBA in slot 5 of the remote node to Switch 3 and Switch 4. In the example, the top port of the Fibre Channel HBA is cabled to Port 8 of Switch 3 and the bottom port is cabled to Port 8 of Switch 4.

2

Cable the second Fibre Channel HBA in slot 8 of the remote node, to Switch 3 and Switch 4. In the example, the top port of the Fibre Channel HBA is cabled to Port 9 of Switch 3 and the bottom port is cabled to Port 9 of Switch 4.

3

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 0 on both Switch 3 and 4. However, any open set of switch ports in this quadrant can be used (limited to ports 0-3 in this configuration).

  1. Connect the Input port of LRC, ESH, or ESH2 Channel A of disk shelf 3, to port 0 on Switch 4.
  2. Connect the Input port of LRC, ESH, or ESH2 Channel B of disk shelf 3, to port 0 on Switch 3.
  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 disk shelf 4.
  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.
4

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 12 on both Switch 3 and 4. However, any open set of switch ports in this quadrant can be used (limited to ports 12-15 in this configuration).

  1. Connect the Input port of LRC, ESH, or ESH2 Channel A on disk shelf 1 to port 12 on Switch 4.
  2. Connect the Input port of LRC, ESH, or ESH2 Channel B on disk shelf 1 to port 12 on Switch 3.
  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 disk shelf 2.
  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.
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, or ESH2 they belong, as shown in the following example:

Example

ha16*> storage show disk -p
PRIMARY      PORT    SECONDARY       PORT    SHELF  BAY
-------      ----    ---------       ----    -----  --
switch3:0.40   A     switch4:0.40     B        5     0
switch4:0.41   B     switch3:0.41     A        5     1
.
.
.
switch3:12.52  B     switch4:12.52    A        6     4
6

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

7

Connect the VI-MC cluster adapter to the switches, with the top port connecting to Switch 3 and the bottom port connecting to Switch 4.

Note
The example shows the VI-MC cluster adapter connecting to switch ports 3 and 13, but you can use any available switch port.

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.
