Abstract
This presentation allows for two or more storage management servers to be in an active high availability (HA) state for the same set of storage devices and copy services relationships; rather than having a single server be in an active HA state and the other servers being in a standby HA state. This makes each HA server to be able to accept commands at any time so that they will not have to issue a takeover command to a standby server just to start issuing commands. This will also ensure that the data replication pairs will continue copying data until an event of an actual disaster; in which the active servers would then cause the data replication to be suspended so that a consistent set of data is secured on the secondary site.
