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
.
The console code that assigns console environment variables counts every I/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.)
