Failure of the remote storage system

If the remote storage system fails, operation continues with the remaining source unit only, in other words with reduced availability; the applications are not stopped. Remote replication cannot be continued. If the source unit subsequently fails, it is then no longer possible to switch to the target unit later.

When the remote storage system and/or the remote link is available again, replication is resumed when a command is entered. This is not the case when the remote storage system needs to be replaced completely after it has failed. Reconfiguration by Service using SHC-OSD is then necessary.
