Clustered source workload being migrated with Platespin Migrate or protected with PlateSpin Forge or PlateSpin Protect.
Splitting clustered volumes on target disk or datastore returns an error "The source volume X: is a shared volume and cannot be re-ordered.". This error occurs when 2 or more volumes are a part of cluster and reside on same physical disk on source. While migrating/protecting these volumes, they are split on different datastores/virtual disks on target VM or physical disks on target physical.
Clustered volumes that exist on one disk must be migrated/protected to a single disk on target. This is a requirement of clustering. Implicitly, this means they must be migrated to the same datastore. It is not possible to keep the two volumes together in a cluster if they are on separate datastores.
