How to convert vNVRAM disk driver from SCSI to vNVME
Applies to
- NetApp ONTAP Select
- NetApp ONTAP 9.5P2 and higher
- ESXi version 6.7 and higher
Description
From version 9.5P10 ONTAP select uses a vNVME driver for vNVRAM. Using NVME over SCSI driver reduces the processing overhead
- This will be default configuration for new ONTAP Select installations on ONTAP 9.5P2 and higher
- Any select cluster upgraded from pre 9.5 will continue to use the SCSI driver
For the clusters which are upgraded to 9.5 a manual procedure is required to use the vNVME controller for vNVRAM disk
- Single node clusters requires a downtime
- HA, this can be accomplished non disruptively by doing storage takeover
