IC67861: PROBLEMS DETECTING ALL PORT TO PORT CONNECTIONS USING SMI EOS AGENT 2.7 FOR MCDATA INTREPID 10000 (I10K)

APAR status

• Closed as microcode or hardware problem.

Error description

• When using the McDATA SMI Agent for EOS, the Topology Viewer may
  show some connections from switch ports to subsystem ports as
  black lines (indicating missing) or not at all.

• Users Affected:
  All customers running TPC and using Brocade EOS SMI Agent 2.7.
  
  Problem Description:
  After running a CIMOM Discovery and Fabric Probe for this
  fabric, not all switch port to subsystem port connections
  could be retrieved by TPC. This is an issue with the Brocade
  EOS SMI Agent 2.7 that has been reported to Brocade.  The user
  most likely will notice this when looking in the Topology
  Viewer Switch view that shows the connections from the switch
  to the connected devices. It's very likely that there is a
  mismatch between what TPC and the Element Manager or EFCM/DCFM
  show regarding the connections.
  
  This is known to occur while monitoring the Intrepid 10000, but
  may occur with other switches too.
  
  Summary of fix:
  The fix for this from Brocade is unknown at this time.  However,
  there is a workaround for this issue from the TPC side. For
  the fabric probe in TPC, two different algorithms can be used.
  This issue only occurs with one of the algorithms, but
  unfortunately is is the default one when the probe is created.
  Therefore, it's necessary to switch to the alternate approach
  after the probe has run for the first time.
  
  Here are the steps:
  
  1. Create a fabric probe as usual
  2. Save the job configuration -> the probe will automatically
  be submitted
  3. After the probe is finished use the TPC CLI as following:
  - Open a Command Window  or Command Shell in the
  Operating System
  - cd C:\Prorgam Files\IBM\TPC\cli or cd
  /opt/IBM/TPC/cli
  -> if TPC is installed in a non-default path use this one here
  - tpctool -url localhost:9550 -user <user> -pwd <password>
  ->  the user and password are the same used to logon in TPC GUI
  - tpctool> setfpplcy -fabric <fabric ww> -property CIM_ALG 0
  -> use the fabric wwn for the Intrepid 10000 Director switch
  4. After this command finishes successfully, go to TPC GUI and
  submit the probe again
  5. Check the probe logfile named like
  user.probe_fabric_ProbeFabrics.xx.xx.log to have following
  messages in it:
  
  BTAFM0614I The task is to probe topology and zoning.
  The probe algorithm is CIM association.
  
  6. After the probe finishes successfully, all port to port
  connections should be displayed in TPC.
  
  Please notice that after switching to the alternate probe
  approach, the run time of the probe will increase
  significantly. This is because the alternate approach is
  memory optimized and the default approach is run time
  optimized.   Refer also to APAR IC68617 regarding a fix that
  is in 4.1.1 FP4 for the alternate probe approach.
