Moving Dynamic Disks
If you move dynamic disks between systems, you may not be able to move the
dynamic disks back to the original host. If you must move the dynamic
disks, move all the dynamic disks from a computer at one time, and make
sure that they are all online and running on the destination system before
you try to import them to the new host. This order is important so that the
disk group name and ID of the primary disk group of the host system is
always retained (if a dynamic disk is present). What makes the difference
is whether there is at least one dynamic disk on the destination system or
not. One problem scenario occurs when there is no dynamic disk on the
destination system (so that that computer ends up with the same disk group
name as the source computer when the disk are moved to it) and then you
want to move the disks back to the source computer. You may encounter a
problem if foreign disks that you are re-imported have the same disk group
name as the local computer.
