4290.0. "Firmware upgrade,lan interconnect-->WEIRD" by PTOJJD::DANZAK () Tue Mar 18 1997 10:20

    
    I noted the following with LAN interconnect and the new V5 MAM.  It
    appears that when upgrading firmware in a module (it doing a reset) and
    with autohealing disabled, weird stuff happened to OTHER modules in the
    hub.
    
    Aarugh.
    
My hub has the following config:


1  Roamabout
2
3
4
5  DECconcentrator 900MX V2.4 or something
6  DECswitch 900EF V1.7 (latest)
7  DECconecntrator 900MX V3.3.4 (latest)
8  DECrepeater 900TM (latest) Ip services module


I noticed odd LAN interconnect behaviour after upgrading some other
concentrators. i.e. after the concentrator RESET it was disconnected 
(i.e. firmware upgrade RESET the concentrator and it lost it's LAN
connections.)

Note, auto healing was NOT enabled.

I upgraded the module in slot 5...and, it lost it's LAn connect.
Also, the DECswitch 900EF appeard to loose it's connect as well as the
concentrator.

A REFRESH to get status, etc., and I tried to reconnect the
modules, etc.  The configs on the screen did *NOT* match the
light state. i.e. the DECswitch and concentrator in slots 6&7 showed
DISCONNECT but their LIGOtype showed CONNECT.

I mucked a bit, connecting and disconnecting the FDDI...but at one
point the connection to thinwire from the 900TM in slot 8 went away!
(at that point, even removing and reinserting the 900TM did *NOT*
reinstate it's default connect...)  (Sounds like it tried to
autoheal in spite of NO autoheal...almost...)

My only recourse was to reset to FACTORY defaults.

I was upgrading lots of concentrators, noticed that the
FDDI of OTHER modules got disconnected when the concentrator
being upgraded reset.  Didn't think much of it at first until
I noticed that the LAN light on the concentrator in slot 7 was
going out - even tho it should not have been effected.

(i.e. I kept slot 7 and 8 in the FDDI ring because if I upgraded a
concentrator - i would loose the slot 7 connect because of no FDDI
neighbor...so I wanted 2 FDDI modules permanently connected to keep
my backplane ring up etc. 
    
    

What version of MCM are you running?

	Dotsie

    V5.0
    
    NOT any FT version but the shipping V5.0.
    

MCM V5.0 and MAM V5.0 do not work together.  Upgrade hub to V5.0, then upgrade 
MCM to V6.0a, then upgrade modules.  LAN Interconnect will be much happier.

    Er, I got confused....it was ALL the latest version.....
    
    MAM version 5
    CLEARvisn V1.1a which has
    MCM V6
    
    Or something like that
