6464.0. "VAX4000 Model 108 SCA error" by QBUS::E_BURKHALTER () Mon Mar 10 1997 12:32

    
    
        I have an field engineer installing (2) VAX 4000 Model 108 systems
        in a dual host configuration.  Systems are running VMS 6.2.
    
        The DSSI interface is a KFDDA-AA.
    
        One system is node number 7 and the other is node 6 at
        the console level.  Both are node 7 if one system is booted
        and we $SHOW CLUSTER/CONT and add LPORT/RPORT.  The remote
        port is shown as node 7.
    
        If one system is booted then the other system is booted,
        they get the message " inappropriate sca control message".
        then we hang.
    
        If one system is at the >>> prompt and the other boots, 
        system operate fine.  If the reverse is true, the 2nd system 
        is fine.
    
        I ask the engineer to give me a sys layout and under show cluster/
        continous things lke RPORT, LPORT etc.
    
        FE hasn't called back with the info at this time.
    
        Has anyone seen this?

   This sounds like an OpenVMS question, not a storage question.  And if
   the console values for the controllers are set at unique DSSI addresses
   and OpenVMS is somehow switching all DSSI addresses to seven, that looks
   like a serious OpenVMS bug.  (If it's just displaying the wrong address,
   that's still a bug.)

   I'll assume the customer or FE has set up the unique DSSI address values
   in the console, power-cycled the systems for good measure, and has then
   confirmed that the console addresses have not somehow mutated before
   OpenVMS has been bootstrapped.

   If so, i'd start with an IPMT.
