IT38666: PROBE OF SPECTRUM SCALE DEVICE WITH LARGE NUMBER OF FILESETS FAILS DUE TO TIMEOUT

APAR status

• Closed as program error.

Error description

• Probe of Spectrum Scale device with large number of filesets
  fails due to timeout. Storage Insights uses the command
  "/usr/lpp/mmfs/bin/mmlsfileset rsrch1 -Ydi" which takes nearly
  two hours to return with results. Timeout should be configurable
  to handle extreme cases such as this..
  

Local fix

• Steps to modify the Probe Timeout:
  ---------------------------
  
  On your Data Collector server:
  
  Locate where the Data Collector is installed,
  for example, DC_HOME
  
  Edit the setup.properties file in DC_HOME/conf/
  
  DC_HOME/conf/setup.properties
  
  Add this line at the bottom of the file contents:
  
  probeTimeout=<time in milliseconds>
  
  For example, to set a 4 hour probe timeout:
  probeTimeout=14400000
  
  Restart the Data Collector.
  
  You can review and verify each device probe is allocated the
  new time by reviewing the trace_message log
  ( Task time out is set to <xx> minutes )
