SAN Boot Environment Requirements

SAN Boot Environment Requirements

This chapter introduces the environment requirements for installing UltraPath when SAN Boot is configured.

If SAN Boot is configured for the host, in addition to doing the above-mentioned work before installing UltraPath, the following requirements must also be met:

  • An operating system (OS) has been installed on the virtual LUN mapped to the host by the Huawei storage system.
  • The virtual LUN running the host operating system must be a common virtual LUN.

In SAN Boot scenarios, do not map the LUN that houses the host's operating system to two or more hosts. Otherwise, operating system data may be inconsistent. Besides, the virtual LUN running the host operating system must be a common virtual LUN.

The procedure for configuring HyperMetro in the SAN Boot scenario is as follows:

  1. Install the operating system on the SAN storage device.
  2. Install UltraPath on the operating system. For details, see 2.3 Installing UltraPath for ESXi.
  3. Configure the HyperMetro feature by referring to related product documentation.

    • Log in to Huawei technical support website ( and enter BC&DR Solution Product Documentation (Active-Active DCs) in the search box to search for, browse, and download corresponding product documents.
    • For UltraPath V100R008C50 and later versions, use the product documentation of V200R001C20.
