14.2.9 OpenVMS AXP and DEC7000 Crash Dump Problems

There are two situations on DEC7000 systems running OpenVMS AXP V6.1 which may

cause only partial crash dumps to be written that are no use for analysis:

On systems with large (512MB+) memories, booted from a system disc via the CI, writing

the dump may stop prematurely with "Halt Code 05". This is caused by a bug in PNBT-

DRIVER.EXE. The ﬁx is to apply the following patch kit:

OpenVMS AXP patchkit, AXPBOOT01_061, available as CSCPAT_2091.

The second problem involves systems booted via DSSI. Here, if a console key is pressed

while the dump is being written, the system may hang. The ﬁx is either not to touch the

console, or to upgrade the console ﬁrmware to V4.1. If you can’t wait for V4.1 a "patched"

version of V4.0 is available from:

PROXY"fal$access"::allen_public:[public]AXP7_IPMT_PC.SYS

14.3 Other Goodies

I have assembled the following information on known problems from BLITZs, STARS, Notes

and local knowledge. Some bits are directly quoted, others I have edited (as you can probably

tell!)

14.3.1 DEC/VAX 7000 Air Flow Pressure Switch Causes System Shutdown

Air ﬂow pressure switch on the CCL module (DEC P/N 54-20300-01) can cause the system to

perform intermittent shutdowns due to false air ﬂow faults. An FCO was issued to replace

CCL module (see Section 13). Temporary ﬁx is to jumper out the pressure switch.

14.3.2 Battery wiring on DEC/VAX 10000s

Failure to observe proper polarity when connecting battery wiring can cause severe power

system damage, overheating and emission of smoke. Note that ORANGE wires are POS-

ITIVE (+) polarity and BLUE wires are NEGATIVE (-) polarity. See "DEC 10000 AXP

SYSTEM VAX 10000 INSTALLATION GUIDE" (EK-100EB-IN.002), sections 2.15, 2.16 and

2.17.

14.3.3 CIXCD Microcode on Alpha/VAX VMSclusters

Only the CIXCD-AC (T2080-YA module) is supported with the Laser platform. It normally

comes loaded with VAX compatible ucode (CIXCD.BIN). However, DEC7000/10000 systems

need different ucode that is AXP compatible (CIMNA.BIN). Factory installed options will be

OK, but if you install one you must run the LFU to load the correct ucode. Field spares

could have either ucode on board so be careful.

14.3.4 VAX 7000/10000 CIXCD Write Error Interupt (WEI) Errors

While booting a VAX 7000/10000, VAX-VMS creates two error log entries that are caused

by the CIXCD testing WEI (write error interrupt) logic. The error log entries appear to be

reporting a real error when they are actually reporting a selftest diagnostic activity. If the

errors have the following footprint, you can safely ignore them.

The errorlog entries only occur when the system is being booted
