Online Addition OLA You can add multiple adapters at the same time While adding an adapter online the first issue you must resolve is whether the new adapter is compatible with the system Each OLAR capable PCI slot provides a set amount of power The replacement adapter cannot require more than the available power The adapter must also operate at the slot s bus frequency A PCI adapter must run at any frequency lower than its maximum capability but an adapter that could operate at only 33 MHz would not work on a bus running at 66 MHz The SCSI A6828A HBA operates at 66MHz The rad command provides information on the bus frequency and power available at a slot as well as other slot related data If your system has one or more slots that support OLAR and you want to use OLA to install the A6828A in one of those slots install the adapter in your HP UX system according to the procedure described in the Managing PCI Cards with OLAR chapter of the Configuring HP UX Peripherals manual After you add a new A6828A adapter SAM tries to locate the SCSI c8xx driver If SAM is unable to locate the driver you cannot use the new adapter until you install the driver remember that driver installation requires a system reboot If SAM locates the driver it determines whether the new adapter is functional If the adapter is not functional SAM displays an error message Online Replacement OLR While replacing an interface adapter online
