Compaq HSG80 Array Controller ACS Version 8.4 Configuration and CLI Reference Guide
Before cabling, note the following:
■ Ports
❏ All ports are active. Once units are added, all ports will have access to the
same units.
❏ Port 1, controller A and port 2, controller A connect into the same switch.
❏ Port 1 controller B and port 2, controller B connect into the same switch.
❏ Port 1 on both controllers connect into the same switch port on different
switches.
❏ Port 2 on both controllers connects into the same switch port on different
controllers.
■ Hosts
❏ Host operating systems may be mixed together or one host may be used for
all host connections, for example, two Windows NT hosts.
1. Configure each controller. See “Configuring in Multiple-Bus Failover Mode,”
page 5–20.
2. Ensure the host and adapter are also configured. See the host user’s guide for
details.
3. Connect the cables between host port 1 on both controllers and the switch ports
on the switches.
IMPORTANT: Each host port 1 cable must go to a different switch, but into the
same switch port. Do not cable them into the same switch.
4. Connect the cables between host port 2 and the switch ports.
IMPORTANT: Each host port 2 cable must go to a different switch, but into the
same switch port. Do not cable them into the same switch.
