How to mount virtual disks from a block snapshot or replication to a VM

It is assumed that a Hyper-V policy that creates hardware snapshots or replications has been implemented and that at least one snapshot or replication has been created. See How to create VM restore points with block snapshots for guidance on how to do this.

Note: Snapshots and replications cannot be used for mount operations if they are currently mounted elsewhere.

This task describes the steps to follow when mounting virtual disks contained within a block snapshot or replication, to an existing VM. This procedure will result in all of the virtual disks from the selected VM backup being mounted as new virtual disks on the target VM. The newly mounted virtual disks appear in addition to any existing virtual disks:

Identify the destination where the virtual disks are to be mounted. The destination host must be represented by a Protector Hyper-V node. If the destination is not represented in Protector, then create one using the Hyper-V Node Wizard
Ensure that the mount location is prepared to receive the virtual disks by locating the host node in the Nodes Inventory and checking it is authorized and online.
Locate the Hyper-V snapshot or replication, containing the virtual disks to be mounted, by clicking the Restore link on the Navigation Sidebar to open the Restore Dashboard. Then click the Hitachi Block button to open the Block Restore Inventory. You must click the Search button to view the list of available snapshots.
Select the Hyper-V snapshot or replication that contains the virtual disks to be mounted. Then click Mount to open the Hyper-V Mount Wizard which will guide you through the mount process.
Select the Virtual Machine that contains the virtual disks to be mounted. Click Next.
Select the Hyper-V Node where the mount target VM is located. Then select the target VM. Click Next.
Select the mount mode and specify the Mount Pool if necessary, then click Finish.
The mount mode determines how the temporary volume, from which the backed up VM(s) are to be taken, will be created during the restore process. For replications, the mount mode is always set to Mount original.
CAUTION:
Select the mount mode depending on the behaviour required:
- Mount Original - Mounts the original snapshot.
  This option will expose your original backup to the Hyper-V host. Any changes will persist even after the unmount. While Protector will not perform any changes, nothing is preventing users or other processes from modifying the data.
- Mount duplicate - Protector will create a cascaded duplicate of the original snapshot and perform the restore from the duplicate. The original snapshot is preserved. Use Cascade mode (the default setting) in the Block Snapshot Configuration Wizard when assigning the snapshot operation on the data flow to enable Mount duplicate when exporting.
A Processing message will appear briefly, then the wizard will close, and the Jobs Inventory will be displayed. A new Restore Job will appear at the top of the Jobs list, with the Progress entry initially indicating processing and finally indicating successful completion.
Once the mount job is complete, further steps may be needed to fix-up the application data on the VM before using it. The amount of fix-up work required depends on the applications hosted on the VM.
It may be necessary to restart the OS on the VM before the newly mounted virtual disks can be used.
