Method and means for bidirectional peer-coupled communication across a single ESCON interface |
摘要 |
A method for establishing bilateral communications over a single ESCON link coupling a pair of control units. The method steps include (a) permitting link address acquisition between directly connected link-level facilities that simultaneously assume the role of a master control unit in a peer-to-peer remote copy (PPRC) configuration, (b) resolving conflicting device-level frames that initiate a path to a device (also termed an I/O connection), and (c) dynamically determining the role assumed by a link-level facility (master or slave) when a single logical path is shared.
