Although a pair of volumes or a pair of groups can be related as the master and the proxy, there are the following exceptions:
Objects that belong to different classes cannot be related as the master and the proxy.
Objects that belong to the same group cannot be related as the master and the proxy.
Stripe type objects cannot be related as the master and the proxy. However, a mirror group to which a lower level stripe group is connected, or a mirror volume within that mirror group, can be related as the master and the proxy. For example, to stripe a master volume, connect a stripe group to a mirror group and create the master volume in the mirror group.
Concatenation type objects cannot be related as the master and the proxy. However, a mirror group to which a lower level concatenation group is connected, or a mirror volume within that mirror group, can be related as the master and the proxy. For example, to concatenate disks to create a large-sized master group, connect a concatenation group to a mirror group and create the mirror group the master group.
For a proxy that is already related to a master, another proxy cannot be related.
A master to which a proxy is already related cannot be related as a proxy to another master.
Shadow class objects cannot be related as the master and the proxy.
