ABSTRACT:
Provided are a method, system, and article of manufacture for copying data. A request is received at a first storage control unit having a first set of volumes, wherein the first storage unit is coupled via a link to a second storage control unit having a second set of volumes that are peer-to-peer copies of the first set of volumes, and wherein the request is for generating a copy of the first and second set of volumes in a third set of volumes in the second storage control unit. A command is transmitted via the link, from the first storage control unit to the second storage control unit, wherein the transmitted command is capable of causing the second storage control unit to generate the copy of the first and second set of volumes in the third set of volumes in the second storage control unit.
