Applies to

  • ONTAP Select
  • ONTAP 9.9.1
  • CPU Sandy Bridge Generation

Issue

Customers having CPUs older than Sandy Bridge or VMWare EVC mode set to older generation than Sandy Bridge will hit failure while upgrading to 9.9.1.

  • The same failure would be seen with fresh installs as well.
  • After image update when the node boots with the new image, it would be printing few "illegal instruction" and subsequent messages in the console as pasted below and system would never come up:
