8919.0. "The official 'panic -> CANASTA' topic" by HAN::HALLE (Volker Halle MCS @HAO DTN 863-5216) Fri Feb 21 1997 02:29

    
    This note will be used to try to explain the usage of CANASTA as the
    first step during system crash analysis. Instead of adding replies to
    every crash-data file posting, I'm using this topic to 'spread the word'
    about CANASTA.
    
    Volker.
    
    
    +++++ CANASTA is a Digital-internal Crashdump Analysis tool. It can 
    
    	- parse Digital UNIX crash-data files
    
    	- match panic footprints against a 'knowledge database' of known panics
    	  (providing solutions or workarounds from CANASTA 'rules')
    
    	- provide a list of 'cases' with the SAME panic footprint (some of
    	  those might have been escalated as IPMTs, QARs etc.). There are 
    	  currently panic footprints from 2617 Digital UNIX crash-data files
    	  in the CANASTA world-wide crash database.
    	
    
    +++++ Using CANASTA for crash analysis is as easy as sending mail...
    
    	  Whenever you get a system panic problem, please obtain the associated
    	  crash-data file (from /var/adm/crash/crash-data.n) and mail it to the
    	  CANASTA Mail server:
    
    	    [email protected]	or    XOCOMP::CAN_SERVER
    
    	  Use a mail subject string of:
    
    	    DIAGNOSE CASE=log-number
    
    	  where	log-number	is your call handling system log-number
    			   	(e.g. C970202-12345   for CHAMP,
    			              12345003551NGY  for NICE,
    				      MGO123456       for IPMT Request ID,
    				      QAR_012345      for QAR number)
    				If you don't have any kind of reference number,
    				omit the CASE=log-number parameter.
    				For additional information, please see note
    				SPECXN::CANASTA #222.3
    
    	  Example:
    
    # Mail -s "DIAGNOSE CASE=test" [email protected] < crash-data.n
    
    
    +++++ Additional information about CANASTA Mail Server
    
    	  Additional information about the CANASTA Mail Server can be obtained
    	  by sending mail with a subject string of 'HELP' or reading notes
    	  SPECXN::CANASTA #222
    
    
    +++++ Automating crash analysis with 'AutoCLUE for Digital UNIX'
    
    	  Customer's with DSNlink for UNIX could take advantage of the
    	  AutoCLUE for UNIX' software. This software will be invoked during boot
    	  after a system panic and will automatically send the crash-data file
    	  to the Digital DSNlink Host, where it can be automatically analyzed 
    	  through CANASTA. Information about AutoCLUE for UNIX can be found
    	  in note CSC32::AUTOCLUE #60.
    
    
    +++++ CANASTA Mail Server via Internet Mail
    
    	  Sending AutoCLUE (crash-data) mails to the CANASTA Mail Server via
    	  Internet from a CUSTOMER SYSTEM is also possible, but no replies will
    	  currently be sent back to any address outside the Digital domain
    	  DEC.COM. If desired, the CANASTA Mail Server reply can be
    	  automatically (on a per-customer domain name basis) forwarded to
    	  a Digital-internal mail address (for explanation and registration
    	  see note CSC32::AUTOCLUE #72).
