Abstract
Provided are a computer program product, system, and method for establishing reverse paths between servers in a copy environment. A path establish request operation is initiated to establish paths between a first system and a second system for a copy relationship to copy data from a first storage to a second storage managed by the second system. In response to the path establish request, a pair of ports is established at the first system and the second system to use for a first path from the first system to the second system. The first system sends a reverse path establish request to establish a second path from the second system to the first system, wherein the second system sends messages to the first system on the second path for the copy relationship.
