Comparing the show pk* command display in Example 2–5 with the show
config command in Example 2–1, you determine that the first two devices
are for ncr0 and ncr1 (pka and pkb). The next two devices are for the
KZPBA-CBs, isp0 and isp1 (pkc and pkd). The last two devices are for
KZPSA-BBs, pks0 and pks1 (pke and pkf).
Example 2–5 shows two pk*0_soft_term environment variables;
pkc0_soft_term which is on, and pkd0_soft_term which is diff.
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 low 8 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
• on—Turns on both low 8 bits and high 8 bits
