50 Administering High Availability for Hyper-V
files have to be moved from the current location to storage LUN(s) that can
be made cluster resources. The recommended mechanism to move VM files is
to use the Export/Import functionality in Hyper-V.
1
Provision a new storage LUN, bring the disk Online on any one cluster
node,
Initialize it, and Format it as NTFS .
2 Use the Failover Cluster Management console to make this storage LUN a
cluster resource. Make sure that this LUN is listed under
Storage → Available Storage .
3 From the Hyper-V Manager Console , select the non-HA VM, and Export
the VM files to the newly provisioned storage LUN.
NOTE: If the storage LUN cluster resource is not owned by this node, the
storage LUN will need to be moved to the node that is currently running the
VM before exporting the VM files.
4 After the Export is complete, delete the existing non-HA VM using the
Hyper-V Manager console .
5 Use the Import functionality to import the VM files from the shared
storage LUN to the same node.
6 Use the guidance provided under "Enabling VMs as HA VMs" on page 39
to complete configuration of the HA VM.
Converting an HA VM to a Non-HA VM
To convert an HA VM to a non-HA VM requires that the VM files be exported
before the files are removed as cluster resources.
1
Use the Failover Cluster console to Shutdown or Turn Off the VM.
NOTE: Do not initiate these actions from the Hyper-V Manager console
because the cluster service will restart the VM to maintain the VM's HA state
2 From the Hyper-V Manager console, Export the virtual machine to an
alternate location (such as a local hard disk). Once the export is complete,
delete the existing VM from
Hyper-V Manager .
3 Use the Failover Clustering console to delete the VM resource group that
is hosting the HA VM. The VHD files have to be deleted manually from
the shared storage.
