X477A to X336A model ID correction process - WVELE04TA07

Last Updated:

Applies to

  • X336A-R6 4TB NL-SAS drive
  • X336_WVELE04TA07 firmware
    • bundled in ONTAP
      • 9.10.1RC1
      • 9.9.1P3
      • 9.8P8
      • 9.6P18
      • 9.5P19


Recently released ONTAP patch releases (9.10.1RC1, 9.9.1P3, 9.8P8, 9.6P18, 9.5P19) included an incorrect FW file for the X336A-R6 4TB HDD SAS drive with Model ID string X336_WVELE04TA07.

  • This FW was posted on the NetApp Support Site (NSS) for a short period of time, as well.
  • As a result, after upgrading ONTAP to this patch release or by downloading the FW from NSS, the background FW update function will download X336_WVELE04TA07.NA01.LOD firmware to the matching Model ID string mentioned above.
  • This firmware update will result in mislabeling the Model ID string being reported in ONTAP.
  • The incorrect drive string for the X336A-R6 drive will report as X477_WVELE04TA07. 

Although there is no functional issue with the Model ID string changing, it could result in an incorrect replacement drive if an RMA were issued for a failed drive.

  • The issue with the Model ID string can be corrected with the process below to revert the model ID string back without replacing the physical drive. 
  • This process will convert all the drives in the system with X477_WVELE04TA07 to X336_WVELE04TA07.

Attention: This process is to be used only on native 12Gb/s SAS3 storage with the earlier reported X336 Model ID string.

  • Do not use this process on 6Gb/s SAS2 storage that include the X477 Model ID for X477A-R6 4TB drives. Following the below process on those systems would change X477 Model ID string to X336 Product ID for the X477A-R6 drive type.

Proactive monitoring of the sysconfig -a output can identify disk drives with the incorrect ID string. 

  • Inspect the disk model ID strings of the storage shelves for any ID strings that begin with X477. 
  • Verify if the model ID is WVELE04TA07.  If the model was previously X336, then the following instructions can be used to change the ID back to X336. 
  • Do not replace any disk drives for this issue.
