Installing the A6828A Adapter

Specifying SCSI Parameters

Bus Width

The firmware suggested default for the A6828A adapter’s bus width is MAX (use the adapter’s maximum bus width [16 bits]). However, either of these rates can be used for the A6828A:

 

•

8 bits (Narrow)

 

•

16 bits (Wide)

 

HP recommends you to always use the A6828A’s maximum bus width

TIP

 

(16 bits), unless you have Narrow (8-bit) devices on the bus and you are

 

experiencing problems with the connection.

 

 

 

You can set the A6828A’s bus width in one or two ways, depending on the HP-UX system the adapter is installed in (refer to Table 2-2 on page 22).

To set the bus width for A6828A HBA installed in PA-RISC based system, see “Setting Bus Width for A6828A Host Bus Adapter Installed in PA-RISC Based System” on page 40.

To set the bus width for A6828A HBA installed in Itanium®-based system, see “Setting Bus Width for A6828A Host Bus Adapter Installed in Itanium‚-Based System” on page 44.
