The size of a proxy volume must be equal to that of the master volume to which it is related.
Note
System Volume's Proxy Volume
When relating each individual proxy volume to a system volume, the proxy volume must be created in the group to which the keep disk with the same cylinder size as the system disk's cylinder size belongs. This is because the system volume size is the multiple of the cylinder size.
When relating each individual proxy group to a group to which system volumes belong, it is not necessary to consider the cylinder size. This is because the proxy group's cylinder size changes to the same size as the joined master group's cylinder size.
