Contributors

If your ONTAP LUNs are not performing as you expect after transition from Data ONTAP operating in 7-Mode, you can rollback from ONTAP to 7-Mode LUNs on a Windows host.

Your 7-Mode LUNs must be remapped to your host.

Steps
  1. Use Hyper-V Manager to shut down all virtual machines (VMs) running on the LUNs.

  2. Use Windows Disk Manager to take the LUNs offline.

  3. Use Cluster Disk Manager to take the cluster disks offline.

  4. Shut down the host.

  5. Revert back to Data ONTAP operating in 7-Mode.

  6. Boot the host.

  7. Use Windows Disk Manager to bring your 7-Mode LUNs online.

  8. Use Cluster Disk Manager to bring cluster disks online.

  9. Use Hyper-V Manager to bring your VMs online.
