IT42599: PERFORMANCE DATA COLLECTIONS TIMES OUT AND DATA COLLECTION SHOWS TASK EXPIRED

APAR status

• Closed as program error.

Error description

• This problem may occur when the Data Collector host
  machine, and the storage devices it is monitoring, do not
  have synchronized times. Such as if the system times
  are out of sync by 5 minutes or more.
  
  When data collection deltas are not calculated for Spectrum
  Virtualize family of products (such as Storwize) it results in
  the PM data being considered as a first data collection which
  then skips the delta calculation, and therefore no Perf data is
  being calculated.  And the SI GUI shows the Performance
  as Task Expired.
  
  LogDNA shows the following

Local fix

• Suggestion to review and confirm the Data Collector host
  machine, and the storage devices it is monitoring, have
  synchronized times. Suggest using a Network Time
  Protocol (NTP) server to ensure the time set on the host
  machine and storage devices are in sync.
