Applies to

  • ONTAP FabricPool
  • VMware ESXi and Guest OS hosted on ESXi
  • VMFS
  • RDMs
  • VVOLs

Issue

  • During ONTAP FabricPool S3 tiering outage, Guest OS hosted on ESXi might report:
    • I/O failures,
    • Read-only filesystems,
    • Guest OS crash, etc.
  • In some cases, VMFS datastore could go read-only/inaccessible.  ESXi vmkernel logs records this as medium errors and I/O failure for Guest OS.

Sample error message from ESXi is shown below:

ESXi Medium error
