Specifying SCSI Parameters

Bus Width

The firmware suggested default for the A6829A 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 A6829A:

	•	8 bits (Narrow)
	•	16 bits (Wide)
	HP recommends you to always use the A6829A’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 A6829A’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 24).

To set the bus width for A6829A HBA installed in PA-RISC based system, see “Setting Bus Width for A6829A Host Bus Adapter Installed in PA-RISC Based System” on page 43.

To set the bus width for A6829A HBA installed in Itanium-based system, see “Setting Bus Width for A6829A Host Bus Adapter Installed in Itanium‚-Based System” on page 47.
