2069.0. "ASE panics on reboot." by SALEM::ARNOLD () Mon May 19 1997 10:50

    We have a TrueCluster configuration consisting of two 4100's with
    one MC card in each connected to a hub.  We installed the software 
    and ran clu_ivp on each machine.  They both suceeded.  
    
    Now when we reboot one of the machines we get an kernel mode panic.
    This panic occurs on either machine and it doesn't happen on every
    reboot.  We do not have any services defined at this time.  
    The crash data and decevent give us know clues as to why the machine
    panics.
    
    Following is what we have when the machine panics:
    
    Disabled LUN on a LUN HTL nexus
    AM found a host at bus 2 target 7, lun 7
    
    trap: invalid memory read access from kernel mode
    
    	faulting virtual address:	0x0000000000000060
    	pc of faulting instruction:	0xfffffc00006323c0
    	ra contents at time of fault:	0xfffffc00006323b8
    	sp contents at time of fault:	0xffffffffa7e371d0
    
    panic (cpu 1): kernel memory fault
    
    The same panic will happen on either machine depending on which one
    is rebooted.  Do I need a service defined?
    
    I can't find a scsi error in the errorlog to point to scsi error.
    
    Has anyone seen anything like this before?  Something that I might
    be missing.
    
    Thanks for any help.

2069.1Provide more crash dataNNTPD::"pelle@zk3.dec.com"Pelle WahlstromMon May 19 1997 13:266
You need to provide more crash data than this. In particular provide the
stack traces from the crash in /var/adm/crash/crash-data.?. This is a minimum.


Without that information nothing very little can be said

2069.2If no crash, use the debuggerNNTPD::"cherkus@buff.zk3.dec.com"Dave CherkusMon May 19 1997 13:3916
We haven't seen this before.  The crash could be due
to cluster code or then again it may not be.

If you don't have a crash, you can feed the memory trap info
into the debugger.  Boot genvmunix (boot -fi genvmunix) and
then start the debugger (dbx -k /vmunix).  Feed the values
for PC and RA into the debugger as follows:

(dbx) 0xfffffc00006323c0/i
(dbx) 0xfffffc00006323b8/i

This will give us the names of the most recent (PC) and 
next-to-most-recent (RA) functions.

    The OS version is 4.0B and TCR14.  
    
    The 4100's are configured as follows:
    
    	2 466 cpu's in each.
    	2 FDDI DAS controllers in each.
    	1 DE500
        2 KZPDA in each for system disk.
    	1 KZPSA for shared bus connected to HSZ50.
    	1 Gig of memory in each.
    
    One thing we found, after changing all the hardware, if we removed one
    of the CPU's out of each box we were unable to get the machine to
    panic.
    
    We have multiple crash dumps if you need more info on this.
    
    Thanks for your help.

2069.6QAR's should not reference an ASE noteSMURF::MYRDALWed May 21 1997 16:107
    Please do not enter QARs that refer to the ASE notes file.  The specific
    information should be put into the QAR for reference.  I have fixed the
    QAR entered for this problem and assinged it to the correct engineer.
    
    Thank you

2069.7v4.0b patchesSALEM::ARNOLDThu May 22 1997 16:3811
    After installing all the v4.0b patches (DUV40BAS00003-19970425) this
    problem has gone away.  At this time I don't know which patch fixed the 
    problem and I was real hesitant to install them not knowing what one to
    install.  
    
    If anyone has an idea which patch would have fixed this I would like
    to know so that I can explain it to the customer.
    
    Thanks for the help.

    	I believe USEG recommends installing ALL patches.
2069.9Customer has requested minimum patches be installedSALEM::ARNOLDFri May 23 1997 17:3312
    I just got a call from the customer and they only want the minimum
    required patches installed to fix the problem.  We tried installing
    just the kernel memory fault patches and the machine paniced.
    
    I don't have a clue as to what other patches I should install and still
    be at the minimum required.
    
    Any help would be appreciated.

2069.10'minimum patches' is unsupportedRHETT::MOOREFri May 23 1997 17:518
    Installing some but not all of the patches is an unsupported
    configuration.  I'm sure the customer wouldn't want to run in
    an unsupported configuration.

    Yes it is.  I didn't know it was all or nothing.
    
    Thanks
