Performing a Non-Disruptive Disk and Shelf Firmware upgrade on a NetApp FAS2040

I received a mail from NetApp this morning, pointing my attention to KB ID 7010014.  In a nutshell, there is a drive firmware upgrade available which the lowers the drive failure rates.  AutoSupport has also been nagging me about out of date DS4243 shelf firmware, so I thought this would be a perfect opportunity to upgrade it all in in one go.  It goes without saying that the upgrades must to have zero impact on client access.  The process below was run on Data Ontap Release 8.1 7-Mode.

Update the Disk Qualification Package

  1. Download the latest DQP from the NetApp support site
  2. Extract the files and copy it to the /etc folder on your filer, overwriting the existing files

Update the Disk Shelf Software

  1. Download the appropriate disk shelf software upgrade from the NetApp support site
  2. Extract and copy it to the /etc/shelf_fw folder on your filer
  3. Run the options shelf.fw.ndu.enable command and verify it is set to on
    • If not, enable it with the options shelf.fw.ndu.enable on command
  4. Execute the storage download shelf command to update the shelf firmware and enter yes when prompted

Update the Disk Firmware

  1. Download the latest disk firmware from the NetApp support site
  2. Verify the following, otherwise you will not be able to do a non-disruptive upgrade
    • Aggregates need to be RAID-DP or mirrored RAID4
    • You need to have functioning spares
  3. Run the options raid.background_disk_fw_update.enable command and verify it is set to on
    • If not, enable it with the options raid.background_disk_fw_update.enable on command
  4. Extract and copy the disk firmware to the /etc/disk_fw folder on your filer
  5. The upgrade should start automatically in a couple of minutes
  6. Repeat for both controllers

Verifying the upgrade

Execute the sysconfig –v command to verify successful installation
And there we go, we have non-disruptively upgraded the firmware and disk drives in our filer!

  2. Hi,
    To make this perfect you should specify the version of Data ONTAP and the mode you are in, 7-Mode or Cluster Mode?
    Nice work.
    Cheers
    Jeff

  4. Hi Ruan,

    what DATAONTAP version were you using at the time you wrote this post? I.e. is this post valid for DATAONTAP 8.x.x?

    Thank you.
