■ One-to-many and multihop volume sets — The Sun SNDR software enables you
to create one-to-many and multihop volume sets. In a one-to-many volume set,
you can replicate data from one primary volume to many secondary volumes
residing on one or more hosts. In a multihop set, the secondary host volume of
one volume set can be the primary host volume of another volume set. See
“One-to-Many and Multihop Volume Sets” on page 18.
