CMMVC8813E: The command failed because the existing volume has mirrored copies in different sites.

Explanation

In a HyperSwap topology, all of the mirrored copies for the existing volume must have a matching site of 1 or 2 (not 3 or none). This configuration ensures that the existing volume itself has a consistent and well-defined site of 1 or 2.

User Response

Ensure that all mirrored copies of the existing volume have a matching site of 1 or 2 and then retry the command.
