Adding target disk LUNs for encryption

The New LUN option is used only if an RKM key vault is configured for the encryption group.
The New LUN option can be used only if replication is enabled for the encryption group.
If the local LUN contains host data, configuring it with the New LUN option would cause the
data on the last 3 blocks of the LUN to be lost. Before using the New LUN option, you must
migrate the contents of the LUN to another LUN that is larger by at least 3 blocks. The new
larger LUN can then used when creating the SRDF pair. The remote LUN of the SRDF pair must
be of the same size. The original smaller LUN with user data can be decommissioned.
