Installing Multipathing Software
Multipathing software must be installed on the hosts to aggregate links when active-active LUNs are mapped to the hosts.
You can use Huawei's UltraPath, the OS native multipathing software, or the DMP multipathing software.
For compatibility requirements of the multipathing software, see the Huawei Storage Interoperability Navigator.
UltraPath is recommended, which is optimized for HyperMetro to identify device locations and reduce the number of interactions between the sites, thereby reducing latency.
