Pause

Pause is a state indicating the suspension of a HyperMetro pair formed by a local file system
and a remote file system.

Force Start

To ensure data consistency when the local and remote storage systems malfunction
simultaneously, HyperMetro stops hosts from accessing both. To quickly restore services, you
can forcibly start the local or remote storage system.

Priority Switchover

Priority switchover indicates that the storage array at the preferred site takes precedence to
provide services for hosts. If the storage array at the preferred site needs to be repaired or
maintained, a priority switchover is performed to enable the storage array at the non-preferred
site to provide services for hosts.

1.3.2 HyperMetro Solution Overview

This section describes the HyperMetro solution network and provides a logical HyperMetro
network topology to show the mapping relationship and data flows between host applications
and storage arrays.

If the storage array in one data center malfunctions, host services are switched to the storage
array in the other data center. If the link between two storage arrays in two data centers is
down, only one storage array can be accessed by hosts. The quorum server determines which
storage array continues providing services.

Network Overview

Fibre Channel networking is used as an example to explain HyperMetro solution network
topology. For details, see
