How-To Generate and Collect NAR Data from VNX Arrays

December 27, 2011
  • Login to the Unisphere console
  • Select the array you want to collect data from

  • Click on the “System” tab, then click on “Monitoring and Alerts

  • Click on “Statistics for Block

  • Click on “Performance Data Logging

  • A “Data Logging” windows will appear.  Configure the settings to match the screenshot below.  Leave the “Archive Interval” set to 600 seconds unless otherwise requested EMC or your EMC Reseller.  Once the settings match click on “START”.

  • Confirm that you wish to continue by clicking “YES”.

 

  • Confirm again that you want to apply these new settings by clicking “YES”.

  • Click “YES” yet again to confirm the data logging warning.

  • Click “OK” to confirm (finally) that the operation was successful.

 

  • You will be returned to the Data Loggin settings window.  Click “OK” to close the window.

  • You will now need to let the data collection run for the specified time period – in this case 3 days.

Retrieving NAR File for VNX from the GUI

  • Now that the NAR data collection process has run for 3 days you will need to retrieve the NAR/NAZ files.
  • Login to the Unisphere console
  • Select the array you want to collect data from

  • Click on the “System” tab, then click on “Monitoring and Alerts

 

  • Click on “Statistics for Block

  • On the right, click on “Retrieve Archive”.

  • In the Retrieve Archives window, select your array and choose SPA. (NAR files are ONLY needed for ONE of the SP’s)
  • Change the “Save File(s) As:” destination to a location that is easy to locate.
  • Highlight the .NAR or .NAZ (if encrypted) files that correspond to the 3 days you collected data for.  The time may be off a little but this will not matter.  There will probably be 4 – 6 files total.
  • Click the “Retreive” button

 

  • Click “YES” to confirm the retrieval in the “Confirm: Retrieve Archives” window.

  • At the bottom of the “Retrieve Archives” window verify that the files complete – this may take a few seconds.
  • Click “Done

  • Go to the destination folder where you retrieved the files to.

  • Upload all the files to EMC or your EMC Reseller as instructed.
