With global-active device, you can achieve data redundancy for volumes between two storage systems, and provide a high availability environment.
Data written to a volume of one storage system is automatically synchronized to a volume of the other storage system. You can then use global-active device without having to be aware of the configuration of the volumes accessed by the server. For details about global-active device, see the Global-Active Device User Guide.
You can use VSP One Block Administrator to configure the remote paths and the quorum disk required for using global-active device. These settings must be configured on both storage systems in the global-active device environment.
If you use a port for external connections as the endpoint of an I/O path from an external storage system to a local storage system, the I/O path might disconnect. Use a route that can be used as an external path. For details about external paths, see the Hitachi Universal Volume Manager User Guide.
You cannot use VSP One Block Administrator to complete tasks that use a port for which the virtual port setting is enabled as a port for external connections for the quorum disk.
