Connecting in Transparent Failover Mode to the Host

Use the following steps and Figure 2–2to connect a pair of dual-redundant controllers to the host:

1.Configure both controllers. See “Configuring Dual-Redundant Controllers in Transparent Failover Mode,” page 2–10.

2.Ensure the host and adapter are also configured. See the host user’s guide for details.

3.Connect two trilink connectors between both controllers going into host Port 1 with a jumper cable:

a.Attach one end of the jumper cable to one trilink.

b.Attach the other end of the jumper cable to the other trilink.

4.Connect the host bus cable onto one end of the trilink connector:

a.For a BA370 enclosure residing in an SW600 cabinet, snap the ferrite bead on the bus cable within one inch of the controller.

5.Connect a terminator on the end of the trilink connector for host Port 1:

a.If the controller is at the end of the host bus, connect a terminator to the other connector on the front of the trilink connector.

b.Otherwise, connect another host bus cable that continues to the next device on the bus. Be sure to install a terminator at the end of the bus.

6.Repeat steps 3, 4, and 5 for host Port 2 on both controllers.

IMPORTANT: The HSZ80 Array Controller has dual-host ports, Port 1 and Port 2, which may be configured at the same time. The configuration in Figure 2–2only shows a connection to host Port 1. However, you may also configure host Port 2 the same way, depending on your system requirements.
