2847.0. "Help with Errorlog from DEChub 900MS crash" by CSC32::R_BUCK (Have been assimilated) Mon Oct 09 1995 14:39

    The following (edited), errorlog information was FAX'd to me from a
    field service engineer.  The DEChub 900MS lost all configuration
    information as far as backplane connections, etc.  Did retain IP
    configuration.
    
    Engineer believes that since re-seating the DECswitch 900EF module the
    customer has not had any other unexpected hub crashes.  Does not know
    of any event that could be related to the original crash.  Engineer 
    states that all modules, and the DEChub 900MS itself, are running with
    recent firmware, i.e., the 4.0 kit.
    
    Basic questions are what does this errorlog information point to?  How
    are entries interpreted? Is there any reference and/or formal
    documentation concerning crash codes on the DEChub?  (the infamous) Any
    known problems that this matches?
    
    I believe the bottom line for the Field Engineer is that he just needs
    to know more about the crash so that he can give the customer a
    reasonable explanation.  Also he wants to be sure that he does not
    start swapping hardware if the problem is specific to firmware. 
    
    Thanks

	Looks to me like the Hub's backplane configuration got corrupted somehow, bad enough to cause the hub to crash several times until it erased it's configuration to stop itself from thrashing. It does not look like a hardware problem; its probably a firmware problem related to the Hub's backplane management. Many bugs were fixed related to backplane configuration in the latest MAM V4.1. I suggest you have them upgrade. DUMP ERROR LOG Current Reset Count: 17 This entry means the hub has crashed too many times in a row and it has erased it's configuration. This includes the IP address, etc. So you were misinformed on this point (maybe someone set the IP address again afterwards): Entry = 14 TimeStamp =00 Reset Count =15 Stop Thrash; Cleared Nonvolatile Data. Dump another entry [Y]/N? y This entry means the hub crashed at 35 seconds uptime, in the routine at PC=41B608. Which routine this is depends on the _exact_ MAM firmware version. But the address is definitely backplane management related: Entry =13 Time Stamp = 0 3500 Reset Count =14 Catch VO=07C SR=2004 PC=41B608 Dump another entry [Y]/N? y The rest of the entries are similar, the hub is crashing due to corrupted configuration: Entry =12 Time Stamp =0 17700 Reset Count =13 Catch VO=07C SR=2004 PC=41B60E Dump another entry [Y]/N? y Entry =11 TimeStamp =0 7100 Reset Count =12 Catch VO=07C SR=2004 PC=41B2FO Dump another entry [Y]/N? y Entry =10 Time Stamp =0 136300 Reset Count =11 Catch VO=07C SR=2009 PC=41B2BC Dump another entry [Y]/N? y Entry =9 Time Stamp =0 10600 ResetCount =10 Catch VO=07C SR=2004 PC=41B2B8 Dump another entry [Y]/N? y No more Error Log entries.

2847.2	Appreciate the explaination	CSC32::R_BUCK	Have been assimilated	`Mon Oct 09 1995 18:58`	7
	Michael, Thanks for taking the time to explain the entries. Will pass the information along to the field engineer along with the suggestion to go ahead and upgrade to the latest firmware. Randall
