4294.0. "URGENT ClearVISN 1.1-MultiChassis problem" by SALEM::BARLOW () Thu Mar 20 1997 11:29

    Problem with MultiChasis Manager for clearVISN 1.1
    
    When we compare Hubwatch to MultiChasis Manager for clearVISN 1.0
    the front pannel display and LAN connections are identical.  I just
    loaded clearVISN 1.1 and MultiChasis Manager no longer looks the 
    same as hubwatch.  Some of the differences are having pink lights
    on some or all of the DECrepeater 900TM group of 8 ports.  We have
    also noticed discrepancies in the Lan interconnect view where the 
    fiber connection from the 900EF does not show connected to the
    fiber lan and yet hubwatch shows this connection.
    
    This must be fixed as soon as possible!!!!!

    What version of the MAM code are you running, and what version of firmware
    are you running on the individual modules? Quite often you will see this
    with version mismatches.
    You should never have this.

    >This must be fixed as soon as possible!!!!!
    
    Yeah you are probably right about that.
    
    >Please contact me with questions and when this has been fixed...

    You are assuming that there is problems with the product. More than likley
    the problem is with your configuration. You have not supplied enough 
    information for anyone to succesfully diagnose this. Perhaps you would
    like to supply the versions of firmware in use etc. Any error logs etc.

    I know we don't have the latest version of firmware on our hubs.  Given
    that updating the HUBs requires disconnecting 100+ people per hub with
    20+ HUBS I am not sure when we will be able to get every HUB and module
    within the HUBS up to date.
    
    My concern is that Version 1.0 of ClearVISN worked fine when comparing 
    HUBwatch with MultiChassis Manager.  Why does upgrading to 1.1 all of a
    sudden make MultiChassis Manager invalid.  If we had to upgrade all of
    our HUBS and every module within our HUB to the latest version, each
    time a new version came out, it could be a full time job.  We are
    trying to get ClearVISN up and running so we can automate the upgrade
    process.  I have a major concern when an application gives false data
    when upgraded (vs a previous version that was correct) and requires
    that all systems and applications be upgraded so they speak the same 
    language.  
    
    All I am asking for is to have MultiChassis Manager of clearVISN 1.1
    operate the same way as it did for clearVISN 1.0.

    One of the many duties of a network manager.

   It does not make it 'invalid' it just makes is a lot harder to manage. 
   Without looking at the code and find out what is different I can't answer
   your question. Only to say that the likes of CLEARvisn development team
   go to a lot of effort. pointing out that you should always run with the
   current version. There is a good reason for it.

   At the end of the day the decision to upgrade is yours, but don't write notes
   blaming the product when you are warned against running with different 
   levels of firmware, and you have chosen not to upgrade. For what ever the 
   reason is.
    
    >I have a major concern when an application gives false data
    
   So do we, which is why we recommend strongly that you run with correct 
   versions of firmware.

   > All I am asking for is to have MultiChassis Manager of clearVISN 1.1

   Why do you think one is called 'clearVISN 1.0' and the other is called
   'clearVISN 1.1'. Because they are different.

Hi Craig -

You have to upgrade your hub to V5.0 before using clearVISN V1.1a to
manage it.  Otherwise it won't work.  The problems you are seeing
with "pink leds" etc are symptoms of the non-working configuration.
If you want to investigate how clearVISN V1.1a works and check out
Flash Loader, upgrade one hub and one PC.  Be sure to leave 
clearVISN 1.0 around for managing the older hubs until all are
upgraded.

4294.5It's a VERY BIG HOLE and needs to be fixedPTOJJD::DANZAKPittsburgher �Sat Mar 22 1997 23:0939
    re: .3
    
    Ahem,
    
    We do *NOT* provide any indication of what the CORRECT version of hub
    firmware is.
    
    Remember, we build PLUMBING for data, you only think about it when it
    breaks.
    
    None of our sales literature explains the need for firmware.  We do not
    provide a way to automatically get updates.
    
    We do NOT provide any guides about things like when you need to assign
    IP addresses to modules.  If you have hubs full of repeaters, have them
    distributed throughout a campus of 6 buildings, about 36 floors, you
    need to put on your damn roller skates and go have an IP address
    assignment party.  (Went through this at Roadway Package Systems). 
    
    AND, if your hubs are remote - i.e. like RPS in Phoenix and you're in
    Pittsburgh, you need to FLY TO PHONIX to set it up.
    
    The idea of all of this integrated firmware simply does not scale
    because we have no way to upgrade it, provide guidelines, etc.
    
    ANd, Roadway Package Systems - based on their DEChub experience at
    their corporate site - will NOT deploy them remotely because they are
    not manageable by their hub vendor's own applications (i.e. CLEARvisn,
    things like changing community strings, setting IP addresses etc.)  We
    *LOST* a 50 state implementation because of that.
    
    And, because of lack of basic remote management features, i.e. like
    simple TELnet, we lost *ALL* of Pitt's campus (50 buildings, user
    population of 60,000 etc.).  
    
    Bottom line - nice equipment - does NOT scale because of lack of some
    basic management functionality.
    
    It is a VERY BIG HOLE.
4294.6Some gotchas...PTOJJD::DANZAKPittsburgher �Sat Mar 22 1997 23:2357
    Note: to .0
    
    Unfortunately, CLEARvisn provides no warning about when it's going to
    suicide your hub, incorrectly report configurations, or perform other
    network management faux-pas.
    
    Before upgrading CLEARvisn, you really do need to be sure to get all
    of the recent firmware, and schedule in a time to make your network
    unavailable to perform the upgrades.
    
    Some notable "gotchas" on upgrades:
    
     - It generally works best if each module in the hub has a TCP/IP 
       address.  This allows you to directly load firmware to it.  Some
       older modules, like DECrepeater 900TMs, can only be loaded if
       they have a TCP/IP address.  
    
       You load a module using the CLEARVISN Flash Loader.  Enter
       the IP address directly to do this.
    
       You can perform a 'hub assisted load' on newer modules.  This 
       is done by using the IP address of the hub, and then the "slot
       number" over on the right of the screen.  The gotcha with this   
       is that it takes extra time to "copy to the hub" and then
       'copy to the module'.  
    
       Bottom line, get EVERY module in your hub an IP address.
    
     - I think that typically you want to upgrade the hub manager first,
       then the individual hub modules.  That way if you upgrade a module
       with firmware beyong the hub capability (i.e. like new
       FDDI configurations etc.) the hub itself doesn't go
       insane.
    
     - With upgrades, some old versions of firmware (i.e. V3) will
       cause the hub to totally loose the MAM code, require that it
       be BOOTPed from the serial port.  If you are upgrading some
       critical production hubs, it's good to have a spare hub on
       hand as a backup.  There are no field tools to recover a hub
       in this state (i.e. CLEARvisn doesn't help you do this, nor
       ancillary tools.)
    
     - Note, some older repeaters don't seem to be able to be upgraded.
       When we tried at one site, we ran into 3 which could NOT be upgraded
       to current code.
    
     - Because of changes to the hub code, etc., the prior verions
        of CLEARVISN won't work on newer hubs and the newer version
        doesn't work on older hubs - ie. it will APPEAR TO WORK, but may
        not.   So if you're upgrading to the CURRENT CLEARVISN, be sure
        to have an EXTRA MANAGEMENT STATION around.  ONE to run the
         OLD software and one to run the new until you get everything
         at the new rev.
    
    Nope, it ain't pretty, nor easy, nor documented.  It's eating our time
    at larger accounts.
    
4294.7The purple LEDs may be result of MCM changeNETCAD::DRAGONMon Mar 31 1997 11:0637
    
    Hi,
    
    	One change that was made to clearVISN MCM V6.0A, which may help
        shed some light on the original problem seen is the following:
    
        With older DECrepeaters/PORTswitches (ie 900TM, 900GM) which have 
        multiple banks of LEDs, MCM will now show purple LEDs if the "Bank 
        Display Button" is in the "Hold" state. That is the state which stops 
        the LEDs from cycling through the different banks. This was done to 
        correct a problem which was less obvious. When the Bank LEDs were in a 
        hold state, MCM was not obtaining full LED information from the device.
        As a result MCM was showing LEDs to be off/black when in fact they
        could have been in any state. Since we cannot get the actual state
        of the LEDs from the device, it was decided that the lack of info. 
        should be made obvious to the user, so that they did not make
        decisions based on bad data. As a result the LEDs are shown purple.
    
        This may or may not be your problem. To see if it is, check out one
        of the DR900TMs that is having this problem and see if the "Bank
        LED Hold" button is in the hold state. If it is, press it so that
        the LEDs cycle and then see what MCM shows for the device's LEDs.
    
        With newer repeaters/PORTswitches (ie 900TP) MCM will now get all LED 
        info. regardless of the state of the "Bank LED Hold" button. There
        is no plan to change this in devices which now exhibit this
        problem. 
    
        On the other topic about MCM/FW mismatch. Steps are being taken to
        not allow a newer version of MCM to operate on an older version of
        MAM in regards to LAN Interconnect. Since Release Notes and warnings
        in the documentation do not seem to matter (until of course someone
        blows away their net) this is the safest course for us to take.    
    
        I hope this info. helps.

  At least one of these "faux-pas" have been fixed.  The clearVISN/MCM
  LAN Interconnect view has been modified to check that the MAM being
  managed is at the correct firmware version.

  Please see note 4297.3 for full details.
