IT34800: ANS9450W DSMMIGFS : NO ELIGIBLE FILESYSTEM FOR TAKEOVER. DURING IBM SPECTRUM PROTECT FOR SPACE MANAGEMENT FAILOVER

APAR status

• Closed as program error.

Error description

• In an error condition that warrants an IBM Spectrum Protect for
  Space Management failover in a Spectrum Scale cluster, the
  mmaddcallback variable %eventNode[.qualifier] is populated by
  Spectrum Scale with a list of 1 or more failed Spectrum Scale
  cluster nodes.
  
  'dsmmigfs' is unable to correctly process this list if it
  includes more than 1 node. This might lead to unsuccessful
  failover with the typical message in dsmerror.log:
  
  ANS9450W dsmmigfs : No eligible filesystem for takeover.
  
  Product versions affected: Spectrum Protect for Space Management
                             clients versions 7.1.x and 8.1.x
                             running on AIX GPFS
                             and Linux GPFS platforms
             Initial impact: Medium

  regardless whether two or more HSM nodes in a cluster are going
  down in parallel.
