IJ29186: AFM MMCOMMON TSPCACHSCAN PROBLEM WITH OLD MINRELEASELEVEL

APAR status

• Closed as program error.

Error description

• problem after upgrading to Spectrum Scale 5.0.5.3 and
  it appears that due to a mismatch between the 5.0.0.1
   minReleaseLevel and the Spectrum Scale code level of
  5.0.5.3  that the mmcommon script was failing to call
  tspcachescan correctly.
  

Local fix

Problem summary

• On clusters having minReleaseLevel
  at 5.0.1, with mixed version nodes
  available from 5.0.1.X through till
  5.0.5.X nodes and where the Gateway
  node is at level 5.0.5.X - the newer
  level of Gateway nodes finds
  it hard to co-exist with the older
  level nodes causing a recovery
  failure repeatedly.
  

Problem conclusion

• Benefits of the solution:
  For mixed version nodes in a
  cluster with Gateway nodes at the
  latest 5.0.5.X levels, the fix
  makes it easier to proceed
  and complete recovery procedures.
  
  Work around:
  None available.
  
  Problem trigger:
  Triggering AFM Fileset recovery on a mixed version
   cluster with Gateway node at the 5.0.5.X level and
   minReleaseLevel on the cluster is at the 5.0.1 level
  
  Symptom:
