With Synchronous replication, you can hand over an in-sync volume collection as part of your disaster recovery strategy. For out-of-sync volume collections, you must unconfigure synchronous replication to gain access to the downstream volumes.
If the replication partners use different access protocols, additional steps are needed to bring the replica online. For example, configuring multi-initiator access is applicable for iSCSI arrays, but is inapplicable for Fibre Channel arrays. By default, Fibre Channel allows multi-initiator access, and you cannot disable it. Access control is done through LUN mapping.
