8 Configuring ExpressPCI Fibre Channel Adapters
ExpressRAID may be used to configure ATTO ExpressPCI adapters, however, entering invalid values
may cause your ExpressPCI adapter to function incorrectly. You may only configure Fibre Channel
busses labeled ATTO Technology. To access the configuration options for the ATTO ExpressPCI host
adapter, double-click the appropriate bus or click the information button next to it.
Access ExpressRAID utilities by clicking on the
drives or devices you wish to modify in the device
