DPM Virtual Machine Recovery Hyper-V Clustering

One task needed for planning for disaster recovery with DPM is the naming of the VM from a clustering point of view.

If all VM’s are created through VMM then will be prefixed with SCVMM but in this example we have created one VM from Cluster Manager and one from VMM

The scenario for this type of recovery is a “dead” cluster or VM’s that was deleted by mistake.

Being able to recovery directly would be preferred but thats not currently a option

This leaves us with VMMTESTB prefixed from a naming point of view with SCMMM and one without when selecting the VM’s from DPM

image

And the view from Cluster Manager

image

And after creating the protection group we are ready to test a recovery

image

And our view from VMM

image

If we need to recover the VM to the orignal source we can just select recover

image

And we can recover to the original instance

image

And to provoke a error

image

We kill the VM from both cluster and hyper-v

image

If we then tries to recover a VM to its Original Instance

image

The recovery dies as we dont have the origianal VM

image

So we need to create a empty VM

image

Point it to a dummy location ,the name needs to match the original VM name

image

And no VHD attached

image

In VMM we can not see the new VMTESTA and the VMTESTA that we delted , this scenario is if the cluster dies and needs to be rebuild but VMM isnt “gone”

image

We can then restore the VM directly

image

We then have the temp clustered VM , we need to delete that

image

And also on the Hyper-V Host , this can also be done from VMM to avoid having to open the settings to find the restore VM

image

And Configure Role

image

And select Virtual Machine

image

And Enable it for HA

image

And last clean up if the VM wasnt deleted from VMM , remove the VM that have missing state
