| Step | Action |
|---|---|
| 1 |
For an F630 filerConnect the filer to disk shelf 0 by

| |
| 2 |
Connect disk shelf 0 to disk shelf 1 by
|
| 3 | Repeat Step 2 by connecting disk shelf 1 to disk shelf 2, and so on, for the number of disk shelves that you have in this loop. |
| 4 | Terminate the daisy-chain by putting a terminator on the LRC card Output/Terminator connector on the last disk shelf. |
| 5 |
For an F630 filerRepeat Steps 1 through 4 for all FC-AL adapters labeled Channel A on the filer. |
For an F740 and an F760 filerFor all remaining FC-AL adapters labeled Channel A on the filer, connect the filer to disk shelf 0 by
Continue by repeating Steps 2 through 4. | |
| 6 | Repeat Steps 1 through 5 for the partner filer. |
For an F630 filerThe cabling for one possible example of a maximum configuration appears as shown in the following figure.

| 7 | Proceed to "How to cable the Channel B loops between your disk shelves in a maximum configuration." |
To cable the Channel B connections of the disk shelves in your cluster, follow these steps.
| Step | Action |
|---|---|
| 1 |
Connect disk shelf 0 to disk shelf 1 by
|
| 2 | Repeat Step 1 by connecting disk shelf 1 to disk shelf 2, and so on, for the number of disk shelves that you have in this loop. |
| 3 | Terminate the daisy-chain by putting a terminator on the LRC Output/Terminator connector on the last disk shelf. |
| 4 | Repeat Steps 1 through 3 for all FC-AL adapters labeled Channel B on the filer. |
| 5 | Repeat Steps 1 through 5 for the partner filer. |
For an F630 filerThe cabling for one possible example of a maximum configuration appears as shown in the following figure. (The Channel A cabling you did previously is also shown.)

Turn on the filers and the disk shelves. Among the system messages are the following:
Loop on adapter 7 is open. If adapter is in use, check cabling and seating of LRC cards in FC shelves. isp2100_init: Initialization failed on FC adapter in slot 7. Only 1 Fibre Channel adapter was detected with attached disks, but there are 2 Fibre Channel adapters on the system. Check the cables and the connections for the adapters and disks. No disks were detected on Fibre Channel port B; this node will be unable to takeover correctly. Note: These messages occur because the Channel B loop has not been completed. |
| 7 | Proceed to "How to connect the filers in a maximum configuration."" |
To connect the filers, follow these steps.
| Step | Action |
|---|---|
| 1 |
Run a cf status command on each filer. The resulting output should be as follows:
cluster monitor not initialized. Interconnect is down. |
| 2 |
Using the 4m cluster interconnect cable, connect the X port of the cluster interconnect adapter on one filer to the X port on the partner filer. Perform a cf status on each filer. The resulting output should be as follows:
cluster monitor not initialized. Y link is down. Note: The cluster interconnect adapter has two ports; the X port is above the Y port. Caution: Verify that you connected the cable to the Y port. Connecting to the wrong port disables the takeover feature. |
| 3 |
Using the 4m cluster interconnect cable, connect the Y port of the cluster interconnect adapter on one filer to the Y port on the partner filer. Perform a cf status on each filer. The resulting output should be as follows:
cluster monitor not initialized. Note: The cluster interconnect adapter has two ports; the Y port is below the X port. Caution: Verify that you connected the cable to the Y port. Connecting to the wrong port disables the takeover feature. |
| 4 | At the consoles of each filer, enter halt to shut down the system. |
| 5 |
Connect the filer to the Channel B LRC card on disk shelf 0 of the partner filer by
|
| 6 | At the console of each filer, enter boot to run the filers. |
The following series of figures illustrates how to complete the Channel B loops to the partner filer for one possible example of a maximum configuration. The assumption is that the cabling between the cluster interconnect adapters is complete.
Note: These figures only show how to complete the Channel B loops to the partner filer; they do not show the cabling between the cluster interconnect adapters in both filers. The cabling between the cluster interconnect adapters is not shown in these figures to reduce the possible confusion resulting from the number of cables involved.
This configuration has four FC-AL adapters in each filer, with two FC-AL adapters on each filer labeled Channel A and two FC-AL adapters on each filer labeled Channel B.
The dashed red line in this figure between the disk shelf on the lower right and the filer on the left illustrates the first completed Channel B loop in this cluster.
The dashed blue line in this figure between the disk shelf on the upper right and the filer on the left illustrates the second completed Channel B loop in this cluster.
The dashed yellow line in this figure between the disk shelf on the lower left and the filer on the right illustrates the third completed Channel B loop in this cluster.
The dashed green line in this figure between the disk shelf on the upper left and the filer on the right illustrates the fourth completed Channel B loop in this cluster.
This configuration has three FC-AL interfaces in each filer, with two FC-AL interfaces on one filer labeled Channel A and one FC-AL interface on each filer labeled Channel B, and with two FC-AL interfaces on the other filer labeled Channel B and one FC-AL interface on each filer labeled Channel A.
The dashed blue line in this figure between the disk shelf on the left and the filer on the right illustrates the first completed Channel B loop in this cluster.
