## About Host Bus Adapters

When a data host is connected to the Sun StorEdge 6920 system by a host bus adapter (HBA), the host bus adapter is an initiator. The HBA is connected by a cable to a Fibre Channel (FC) port on the I/O section of the service panel.

After connecting a data host directly to the system with one or two HBAs, use the `luxadm`(1M) command to verify the firmware level of HBAs. If the firmware is not at the correct revision, use the Sun StorEdge 6920 Installation Host CD to install the Sun StorEdge SAN Foundation software. You can then configure the initiator.
