APAR status

• Closed as program error.

Error description

• Due to the fact that CIMOM discovery is started at the
  beginning of the storage probe, if you run some probes on
  the same time for the storages managed by the same CIMOM,
  we can hit an issue when some storages enter in unreachable
  state due to the fact that the T_RES_CIMKEY_SUBSYSTEM entries
  are missing.
  Error Message: HWN021801E CIMOMManager failed to get CIMOM
  entity from database.
  The affected storages have the status: Unreachable
