5.3 Understanding CacheCade Behavior During a Failover
A CacheCade VD possesses properties that are similar to a VD with exclusive host access, and it is not presented to the
host operating system. Therefore, the CacheCade volume does not cache read I/Os for VDs that are managed by the
peer controller node.
Foreign import of a CacheCade VD is not permitted. To migrate a CacheCade VD from one controller node to another,
you must delete it from the controller node that currently manages it and then recreate the CacheCade VD on the
peer controller node.
