Error ID 70094: ASR Protection cannot be enable for HYPER-V VM

I came across above error when tried to setup ASR using new portal. Every step went find until I get below error,

clearly this highlight I cannot replicate the VM successfully to the Azure Recovery Vault. I’ve tried re-registering the Azure Site Recovery agent on the HYPER-V host as well. Though HYPER-V host register properly on the Recovery Vault VM protection fails with above error. On the hyper-v console I can see VM replication is on error state.

So finally meddle around the host logs I found out ASR has been setup previously and has not been removed properly. This means each VM replication also not completed and hanging around on error state. Only way to proceed is to clear those unsuccessful replication data on the host side targeting individual VM’s which is effected.

You need to run below mention PS command on each host targeting the effected VMs,

“$vmName = “<VM Name>”
  $hostName  = “<Host name>”
  $vm = Get-WmiObject -Namespace “root\virtualization\v2” -Query “Select * From Msvm_ComputerSystem Where ElementName = ‘$vmName'” -computername $hostName
  $replicationService = Get-WmiObject -Namespace “root\virtualization\v2”  -Query “Select * From Msvm_ReplicationService”  -computername $hostName
  $replicationService.RemoveReplicationRelationship($vm.__PATH)“

PS: Replace the <VM Name> with your effected VM name, <Host name> with your HYPER-V server name and run on the HYPER-V host.

Once that completed go ahead and try enabling replication for each VM from Azure console side.

PS: If you need to know about how to setup ASR on the new portal you’re in luck. Stay tune for next blog article Smile
