IT35373: LEVEL 4 SUPPORT LOG COLLECTION FAILS FOR IBM SVC CLUSTER WITHOUTENCLOSURES TO DUMP

APAR status

• Closed as program error.

Error description

• Storage Insights fails to generate a Level 4 support log
  package for SVC clusters which do not contain enclosures; the
  devices themselves can generate the log packages when Storage
  Insights is not used.

  2020-12-24 08:56:02.664 HWNEP0112E The CLI
  command that was issued for the storage system failed and
  generated the following error: Livedump SES Dump: Errors

  com.ibm.tpc.common.ep.svc.connect.CommandFailedException:
  Livedump SES Dump: Errors encountered when collecting sesdumps
  .....
  
  
  The messages above shows that the "Livedump SES Dump"
  command encounters errors when collecting sesdumps, however
  there are no CMMVCxxxx warning (W) or error (E) messages to be
  seen.
  
  Further investigation has shown that when there are no
  enclosures
  to collect the "SCSI Enclosure Services (SES)" dumps
  (reference the [svc_livedump-gui1] Output string: Livedump -
  Enclosure
  Dump: No enclosures to dump), the command gives an error because
  
  can't get the livedump from the enclosures as no enclosures
  found on the
  SVC.
  
  When running the snap type 4 log package creation outside
  of Storage Insights, the result is a livedump log package being
  collected, and it works despite the error message about the SES
  Dumps which causes the job to fail when run from Storage
  Insights.
  
  Storage Insights will be made to tolerate the warning message,
  and not
  allow it to prevent the log collection from being completed.
