Connecting hosts directly to the controller unit
Use this procedure to connect up to four hosts, with two host adapters each, directly to the
controller unit. If you are connecting five or more hosts to the controller unit, go to
"Connecting hosts using external devices" on page
Before proceeding, make sure that you connect Fiber Channel interface cables to all host
adapters that you are connecting to the controller unit.
Important: Host mini-hub 1 and mini-hub 3 correspond to Controller A (top) and
mini-hub 2 and mini-hub 4 correspond to Controller B (bottom). To ensure
redundancy, connect each host to both controllers. You can use either the
upper or lower ports on either mini-hub. The example in the following
procedure uses the upper ports for Hosts 1 and 4 and the lower ports for
Hosts 2 and 3.
1 Connect the first host (Host 1) to the controller unit, as shown in
Connect Host Adapter 1 (HA1) from Host 1 to a port on host mini-hub 1. Connect HA2
from Host 1 to mini-hub 2. To connect a second host, continue with
go to
"Connecting secondary interface cables" on page
2 Connect a second host (Host 2) to the controller unit, as shown in
36.
Attach HA1 from Host 2 to the unoccupied port on mini-hub 1. Attach HA2 from
Host 2 to the unoccupied port on mini-hub 2. To connect a third host, continue with

3; otherwise, go to
3 Connect a third host (Host 3) to the controller unit, as shown in
Attach HA1 from Host 3 to mini-hub 3. Attach HA2 from Host 3 to mini-hub 4. To
connect a fourth host, continue with

4 Connect a fourth host (Host 4) to the controller unit, as shown in
Attach HA1 and HA2 from Host 4 to the two unoccupied ports on mini-hub 3 and
mini-hub 4.
