Abstract:
A system for responding to a failure in an active/active system is provided. It may be determined that a failure has occurred in connection with a first site and a second site. A winning site and a losing site may be determined from among the first site and the second site. It may be determined whether to perform at least one of: a push operation, a pull operation or both to obtain or identify data from the losing site in order to maintain I/O operations on the data at the winning site. A message may be sent to the losing site concerning the data. The message may depend on whether to perform the push operation, the pull operation or both. A response to the message may be received.
