pk*0_host_id
Sets the controller host bus node ID to a value between 0 and 7.
Each SCSI bus in the system requires a controller. Buses can theoretically support up
to eight devices; however, the eighth device must always be a controller. Each device
on the bus, including the controller, must have a unique ID, which is a number
between 0 and 7. This is the bus node ID number.
On each bus, the default bus node ID for the controller is set to 7. You do not need to
change the controller bus node ID unless you place two or more controllers on the
same bus.
To list the controllers on your system, enter the command show device. SCSI devices
begin with the letters "pk" (for example, pka0). The third letter is the adapter ID for
the controller. When entering the command set pk*0_host_id, replace the asterisk
with the adapter ID letter.
The syntax is:
set pk*_host_id scsi_node_id
The value for scsi_node_id is the bus node ID, a number from 0 to 7.
pk*0_soft_term
Enables or disables SCSI terminators. This command applies to systems that use the
QLogic ISP1040 SCSI controller.
The QLogic ISP1040 SCSI controller implements the 16-bit wide SCSI bus. The
QLogic module has two terminators, one for the low eight bits and one for the high
eight bits.
The syntax is:
set pk*0_soft_term value
The options for value are:
off Disables termination of all 16 bits.
low (default) Enables low eight bits and disables high eight bits.
high Enables high eight bits and disables low eight bits.
on Enables all 16 bits.
diff Places the bus in differential mode.
