3276.0. "Problem creating spanning tree map" by VCSESU::WADE (Bill Wade, VAXc Systems & Support Eng) Tue Jun 30 1992 13:52

    I having a problem creating a spanning tree map.
    
    When I try to create a spanning tree map I get the following error in
    the MCC_STM_FM_CONFIG_MESSAGES.LOG file -
    
    *** Spanning Tree Map FM (STM_FM) T1.2.7 Messages ***

3276.1Two problems hereQUIVER::HAROKOPUSTue Jun 30 1992 17:0734
Hi Bill,


It looks like there are two problems here:


1) >    (E)  Cannot find/poll spanning tree root: 08-00-7C-00-18-1A

You have a Vitalink root.  In the T1.2.7 version no map can be 
generated for a non-Digital bridge root.   In the SSB version I have added a 
work around for this that I can make available to you.   But let's
see if we can figure out the second problem first because it appears
to be unrelated.


2) >    (E)  Error opening map file for domain: LOCAL_NS:.config


This means that the map file for this domain could not be opened.   I 
don't know why this happened because it looks like you have a valid domain.
It could be one of the following:

1) What is the definition of MCC_MAPS? 

2) Is the area pointed to by MCC_MAPS protected?

3) Are you able to manually add entries to the domain and save a map file? 

4) Another unrelated question.  Are you running on VMS or ULTRIX?

Thanks,

Bob

	Yup, I know a Vitalink is the root and I knew that was one problem with
	getting the map. 

	Please send the work around.

Also,  I get the same map file open error with the FDDI automap but it updates
the map.  All I get though is the default FDDI icon for all the entities with
no connections drawn.  This is the FDDI automap log file-

Hi Bill,

This one has been driving me crazy for a while (note 3080 also has this 
problem) but I finally figured out the problem.   The routine that opens the map file
is using the logical name translation of MCC_MAPS in the file name.
You have it defined to mcc_common (no colin).   The routine is not adding the 
colin to the logical and thus it is trying to open an illegal file name.

I'll fix this for SSB and give it to you to try out.  But in the mean time
if you change your mcc_maps definition to:

define mcc_maps mcc_common: 

it should work.   Give this a try with your FDDI ring map and let me know
if it works.

Thanks,

Bob
3276.4No luck!VCSESU::WADEBill Wade, VAXc Systems & Support EngWed Jul 01 1992 16:2925
   
    I did - 
    MELISA:: DEF MCC_MAP MCC_COMMON:/SYST
    and NO LUCK
   
    I get the same error and from the decterm window I get this (which is
    the same as before but I thought you'd like to see it) -

3276.5Bugs fixedQUIVER::HAROKOPUSMon Jul 06 1992 10:3010
Bill has found two problems here.  The first was the problem opening the
map file and the second was a memory clobber that occured during cleanup
whenever the map file could not be opened.   Both of these problems
have been fixed and the fixes will ship with the SSB kit.

For now the workaround in .3 will solve this problem (Bill redefined MCC_MAP
instead of MCC_MAPS and that's why it didn't work the first time).
