BUGCHECK after reboot

Hello,

i'm currently using alpha DS25 under VMS 7.3-2

since i've installed patch "DEC-AXPVMS-TCPIP-ECO-V0504-152.1" i've sometime (not always)the following problem after reboot

The startup procedure stop after write than eia0 port has been set to 100 Mb Full by console

then the system reboot and a bugcheck procedure is called (process : startup, new image : sysman.exe)

after that the system reboot and start normally.

What exactly happened ? what is the trouble ?

i need help

Re: BUGCHECK after reboot

One thing that comes to my mind: Though you set your port to 100Mb FullDuplex, what is your switch doing? IIRC there are some issues with certain combinations of NIC and switch that cause trouble. Though I cannot imagine why this should be a problem here - unless you try to access the network in your startup (Decnet!) and TCPIP is doing something nasty.

The most annoying part of your question is:

... sometimes (not always) ...


Does this happen as well if you cycle power in stead of reboot without? In that case, it _might_ be an idea to force a bus reset prior to booting. There is a SRM variable for that but I cannot recall which one by heart.

Re: BUGCHECK after reboot

If you have a support contract for this system then send the CLUE crash file (should be in SYS$ERRORLOG) to hp where it can be looked at. It may be due to boot_reset issues like Willem said or many other things.

Re: BUGCHECK after reboot

and about SRM variables, memory_test should equal full and nothing else. Partial can give subtle and annoying problems.

Re: BUGCHECK after reboot

Ian,

two remarks:

Given the location, it's pretty possible there is no crashdump (SYSDUMP.DMP) at all, an incomplete (or even invalid) one, or no valid data in SYS$ERRORLOG.DMP. (Or am I mistaken here). I had similar problesm just a moth or so ago and NO data at all - but on the (graphic) console.

Just suppose there is a crshdump, it would be of no use if there is no support contract....

Gerard,
Good sugestion. I'll do it myself (had mem problems) - new thread on this.
Berlioz - follow that recommendation, since the intermittend occurrence.

Re: BUGCHECK after reboot

Without the output of at least the 1st page of SDA> CLUE CRASH from the dumpfile (which is part of the CLUE file, as mentioned by Ian - see CLUE$COLLECT:CLUE$node_ddmmyy_hhmm.LIS) everything is speculation...

SYSMAN may just be executing IO AUTO and touching the LAN interface, which may have been in a strange state after shutdown.

Re: BUGCHECK after reboot

thanks for all (i apologized for my poor english too)

i've no support a that time (i've asked for it to my commercial but...)

> "sometimes" : it seems to worked better when the speed is fixed on the switch (100 Full) and when i started computer from button

Re: BUGCHECK after reboot

So it's a MACHINECHK (whenever you talk about a system crash, try to at least mention the bugcheck type in the problem description), which is more likely to be caused by hardware, but can also be due to drivers incorrectly accessing/loading device registers.

For a MACHINECHK crash, start with SDA> CLUE ERRLOG to extract the errlog information from the dumpfile and analyse CLUE$ERRLOG.SYS with your favourite ERRLOG analyzer tool (DECevent, SEA/WSEA, ELV).

Starting with V7.3-1, you can also find the Interrupted PC/PS correctly decoded on the stack. Look in the CLUE file for Saved PC/Saved PS below Interrupt/Exception Frame: and check the symbolic address (execlet/driver) of the saved PC. It can be a hint where the problem may be coming from.

how accessing sda> ?

Re: BUGCHECK after reboot

Some crashdump basics:

$ ANAL/CRASH name-of-system-dump-file (by default: SYS$SYSTEM:SYSDUMP.DMP, but can be on another disk when using DOSD = Dump Off System Disk).

The System Dump Analyzer (SDA) will prompt you with SDA>

SDA> CLUE ERRLOG will show you the errlog buffers from the dumpfile and extract them into CLUE$ERRLOG.SYS file in your current default directory.

Re: BUGCHECK after reboot

Berlioz,

you had once, because the CLUE file you've shown has been created from a valid system dump file during system startup (by running CLUE$STARTUP.COM). Note that there is only one system dump file, which gets written into, if the system crashes.

SYS$ERRLOG.DMP is another file into which the system writes the errlog buffers during crash or shutdown. And it's contents is used to make sure the most recent errlog entries still in memory (before crash or shutdown) get copied to ERRLOG.SYS on the next boot.

What does ANAL/CRASH SYS$SYSTEM: return on your system ?

Re: BUGCHECK after reboot

I would guess at a memory problem - anything in the error log?

Re: BUGCHECK after reboot

as you have VMS V7.3-2 You can use ANAL/ERROR/ELV to look at your error log to see if there are any memory related entries

Re: BUGCHECK after reboot

Berlioz,



Machine Check 660


I remember that one, we have had it more than once.

You have eigther faulty SCSI card, or the Y-
connector on your SCSI bus is damaged.

You will have to call hardware support to find out which, and have it replaced.

Re: BUGCHECK after reboot

Berlioz,

you cannot determine the problem from the machine check type, you need to analyze the errlog file with the 'correct' tool for your platform - in case of a DS25 it's WEBES (WSEA). I doubt that ELV will fully translate a MCHECK 660 entry.

In general, there are 4 different machine checks defined in the Alpha architecture:

620 - System corrected error interrupt
630 - Processor corrected error interrupt
660 - System machine check abort
670 - Processor machine check abort

If you don't mind, you can mail me (see my forum profile) the CLUE$ERRLOG.SYS file.
