Usage Guidelines

When the LUN mapping of a remote disk array changes, the local disk array cannot sense the change. You need to manually scan for LUNs on the local storage system and update the LUN mapping change of the remote disk array in a timely manner. Therefore, when a LUN mapping is added to or deleted from a remote disk array, or an initiator is added to or deleted from a host group, you must manually run this command.
