4.3.3.1 Displaying KZPBA-CB pk* or isp* Console Environment Variables

To determine the console environment variables to use, execute the show pk* and show isp* console commands.

Example 4–5 shows the pk console environment variables for an AlphaServer DS20.

Example 4–5: Displaying the pk* Console Environment Variables on an AlphaServer DS20 System

P00>>>show pk*

pka0_disconnect 1

pka0_fast1

pka0_host_id7

pkb0_disconnect 1

pkb0_fast1

pkb0_host_id7

pkc0_host_id7

pkc0_soft_termon

pkd0_host_id7

pkd0_soft_termon

Comparing the show pk* command display in Example 4–5 with the show config command in Example 4–1, you determine that the first two devices shown in Example 4–5, pkao and pkb0 are for NCR 53C875 SCSI controllers. The next two devices, pkc0 and pkd0, shown in Example 4–1 as Qlogic ISP1020 devices, are KZPBA-CBs, which are really Qlogic ISP1040 devices (regardless of what the console says).

Our interest then, is in pkc0 and pkd0.

Example 4–5 shows two pk*0_soft_term environment variables, pkc0_soft_term and pkd0_soft_term, both of which are on.

The pk*0_soft_term environment variable applies to systems using the QLogic ISP1020 SCSI controller, which implements the 16-bit wide SCSI bus and uses dynamic termination.

The QLogic ISP1020 module has two terminators, one for the 8 low bits and one for the high 8 bits. There are five possible values for pk*0_soft_term:

•off — Turns off both low 8 bits and high 8 bits

•low — Turns on low 8 bits and turns off high 8 bits

•high — Turns on high 8 bits and turns off low 8 bits
