2.18.15 pk*0_host_id
Sets the controller host bus node ID to a value between 0 and 7.
Syntax: set pk*_host_id scsi_node_id
where scsi_node_id is the bus node ID, a number from 0 to 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.
2.18.16 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.
Syntax: set pk*0_soft_term value
where value can be:
Off
Disables termination of all 16 bits.
(default) low
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.
