You can configure vSphere HA for PMem VMs in write-through mode, so that when a host fails VMs can be restored on another functioning host.

Prerequisites

  • You must select Hardware version 19.
  • PMem VMs with vPMemDisks are not supported.

Procedure

  1. When creating a new VM in the New Virtual Machine wizard, select Customize hardware.
    1. Click ADD NEW DEVICE and select Add NVDIMM from the drop-down menu.
    2. Click the checkbox Allow failover on another host for all NVDIMM devices.
    3. Click NEXT and complete the New Virtual Machine wizard.
      On Host failure, NVDIMM PMem data cannot be recovered. By default, HA will not attempt to restart this virtual machine on another host. Allowing HA on host failure to failover the virtual machine, will restart the virtual machine on another host with a new, empty NVDIMM.
  2. To enable HA on an existing VM, browse to the VM.
    1. Under VM Hardware, click EDIT.
    2. Select the NVDIMM.
    3. Click the checkbox Allow failover on another host for all NVDIMM devices.
    4. Click OK.
      On host failure, HA will restart this virtual machine on another host with new, empty NVDIMMs.
