Modifying a Protected RDM Volume

Managing VPGs : Modifying Protected Virtual Machine Volumes : Modifying a Protected RDM Volume

If a RDM volume for a protected virtual machine is replicated to an RDM volume in the recovery site and the protected RDM volume is resized, it is not automatically resized in the recovery site.

Note: If the RDM volume is replicated to a VMDK in the recovery site, the recovery site VMDK is automatically resized when the protected site RDM is resized.

To enable protecting a VPG after resizing a protected virtual machine RDM volume:

1. Remove the protected virtual machine from the VPG.

Note: If the VPG contains more than one virtual machine, remove the protected virtual machine from the VPG, and save the changes. If the VPG contains only one virtual machine, delete the VPG, and, if the virtual machine target disks are of VMDK format, make sure to choose to keep the target disks when the option is displayed.

2. Resize the RDM (both local and remote) as described in the VMware Expanding the size of a Raw Device Mapping (RDM) knowledge base article.

Note: The vCenter will not detect that RDMs were resized unless this procedure is followed.

3. Protect the virtual machine again after resizing the RDM.

At this point, the VPG will go through a Delta Sync to compare protected and recovery volumes for changes, and once synchronized, it will enter the Meeting SLA state.
