Storage vMotion Compatibility with Datastore Clusters
A datastore cluster has certain vSphere Storage vMotion
®
requirements.
n
The host must be running a version of ESXi that supports Storage vMotion.
n
The host must have write access to both the source datastore and the destination datastore.
n
The host must have enough free memory resources to accommodate Storage vMotion.
n
The destination datastore must have sufficient disk space.
n
The destination datastore must not be in maintenance mode or entering maintenance mode.
