For a Remote Copy pair with asynchronous periodic mode volume groups, when a failure
occurs (for example InServ2 becomes unavailable) such that all links between the storage
servers are broken, after 60 seconds the system marks the sending links as Down. After
another 200 seconds, the system marks the targets and groups as failed.
