David, That's a very good question. OpenTech Systems VDR product will make the necessary updates to the MCDS so that HSM will know about the new volumes. Whether VDR is restoring primary or alternate copies the MCDS will be updated correctly.

How do you update the HSM CDSs to point to the new vol sers? Actually I have the same question for the previous post using Opentech VDR.
