Multipathing Software Installation

Multipathing Software Installation

Multipathing software must be installed on the hosts to aggregate links when active-active LUNs are mapped to the hosts.

You can use either Huawei's UltraPath or the OS native multipathing software. For compatibility requirements of the multipathing software, see the OceanStor Interoperability Navigator.

NOTE:
  • UltraPath is recommended, which is optimized for HyperMetro to identify device locations and reduce cross-site accesses and latency.
  • To use OS native multipathing software on the application server, you must enable Uses third-party multipath software for initiators on Huawei storage. After this function is enabled, OS native multipathing software can identify and aggregate LUNs for servers to ensure normal service operations.

Installing UltraPath

This section describes how to install UltraPath.

  • UltraPath must be installed on all hosts.
  • For the detailed installation method, see the UltraPath user guide corresponding to your host OS.
    NOTE:

    Log in to http://support.huawei.com/enterprise/ and search for the UltraPath user guide.
