Virtual Disk Expansion

A Virtual Disk Expansion (VDE) is a modification operation that increases the capacity of a standard virtual disk or a snapshot repository virtual disk. The increase in capacity is achieved by using the free capacity that is available in the disk group of the standard virtual disk or the snapshot repository virtual disk.

This modification operation is considered to be ‘dynamic because you can continually access data on disk groups, virtual disks, and physical disks throughout the entire operation.

A VDE operation can be performed on a primary virtual disk or a secondary virtual disk of a replication relationship.

You cannot perform a VDE operation on a replication repository virtual disk.
