The KZPBA-CB is a Qlogic ISP1040 module, and its termination is
determined by the presence or absence of internal termination resistor SIPs
RM1-RM8. Therefore, the pk*0_soft_term environment variable has no
meaning and it may be ignored.
Example 4–6 shows the use of the show isp console command to display
the console environment variables for KZPBA-CBs on an AlphaServer 8x00.

Both Example 4–3 and Example 4–4 show five isp devices; isp0,isp1,
isp2,isp3, and isp4. In Example 4–6, the show isp* console command
shows isp0,isp1,isp2,isp3, and isp5.
Theconsole code thatassigns console environment variables counts everyI/O
adapter including the KZPAA,which is the device after isp3, and therefore
logically isp4 in the numbering scheme. The show isp console command
skips over isp4 because the KZPAA is not a QLogic 1020/1040 class module.
Example 4–3 and Example 4–4 show that isp0,isp1,isp2, and isp3
are devices on the internal KFTIA PCI bus and not on a shared SCSI bus.
Only isp4, the KZPBA-CB, is on a shared SCSI bus (and the show isp
console command displays it as isp5). The other three shared SCSI buses
use KZPSA-BBs (Use the show pk* console command to display the KZPSA
console environment variables.)
