You can get the BIOS version from either:

  • The console (during the failed boot)
  • Within maintenance mode (using sysconfig -v)
  • or from ONTAP  sysconfig -v output

::> run -node <node_name| local> -command sysconfig -v

  • If this occurred during the middle of an ONTAP upgrade; perform the BIOS update and resume the upgrade
