vSphere Replication and RDMs

Jump to solution

Hi,

I have a site that I set up that has Windows 2012 R2 guests with RDMs set in physical compatibility mode.  When I go through the vSphere Replication wizard for these servers I can configure replication for the guest and as expected I cannot set it up for the RDM (which is fine, I have those covered by the SRA) but on the last step it errors out with the following:

Configure a virtual machine for replication

VRM Server runtime error. Please check the

documentation for any troubleshooting information. The

detailed exception is: 'HMS can not set disk UUID for

disks of VM : ManagedObjectReference: type =

VirtualMachine, value = vm-34, serverGuid = C5ABE757-

9697-4C6A-A36B-F98F72EFB5GG'.

Isn't it possible to skip the RDM or is that not my issue?

Thanks

Thom

Physical mode RDM is not supported by vSphere Replication and there is a know issue that you cannot configure replication for VM with physical mode RDM even if you exclude this disk from replication.

Check the release notes: VMware vSphere Replication 5.5.1 Release Notes

Cannot configure a virtual machine with physical mode RDM disk even if the disk is excluded from replication.

If you configure a replication for a virtual machine with physical mode, you might see the following error:

VRM Server generic error. Check the documentation for any troubleshooting information. The detailed exception is: HMS can not set disk UUID for disks of VM : MoRef: type = VirtualMachine, value = , serverGuid = null'.

Workaround: None.

FYI, I ended up using the SRA for the systems with the RDMs.  Thanks for the assist.
