This section describes the precautions about configuration operations performed on other types of Huawei storage systems whose LUNs are hosted by the OceanStor 2200 V3/2600 V3.

  • Do not select the ALUA mode for initiators.
    NOTE:

    It applies to all Huawei storage systems in a non-online hosting scenario.

  • When creating a host, set its type to Linux.
    NOTE:

    It applies to all Huawei storage systems in a non-online hosting scenario.

  • Do not enable CHAP authentication for iSCSI connections.
    NOTE:

    Do not do this for Huawei T series storage system.

  • Before mapping multiple thin LUNs to the local storage system, weigh the I/O pressure on the host that delivers services. Assess whether the service I/O pressure on the host remains within the capability of the thin LUNs on the heterogenous storage systems.
    NOTE:

    Do not do this for Huawei T series storage system.

  • Do not map command devices to the local storage system for hosting.
    NOTE:

    Do not do this for Huawei T/Dorado series storage system.

  • If external LUNs are mapped to the local storage system through the default host group, the LUN information cannot be updated automatically. In this case, manually scan for LUNs.
    NOTE:

    It applies to Huawei T series storage system.

  • If OceanStor UltraPath is used, note the following:
    • When OceanStor UltraPath of which the version is earlier than V100R008C20 is installed on an application server, you can use the online takeover function of the local storage system to create eDevLUNs whose LUN masquerading type is Extended masquerading and use the eDevLUNs to take over external LUNs online, or you can use the offline takeover function.
      After the takeover, if OceanStor UltraPath is upgraded to V100R008C20 or later, perform the following operations to ensure the functionality of the SmartVirtualization feature and storage systems' new features as well as for the online takeover by using the basic masquerading function:
      1. Cancel the mappings of the eDevLUNs and scan for LUNs on the application server.
      2. Change the masquerading properties of eDevLUNs to No Masquerading, see descriptions in Modifying the Advanced Properties of an eDevLUN.
      3. Add the mappings of the eDevLUNs and scan for LUNs on the application server.

      If OceanStor UltraPath needs to be upgraded to V100R008C20 or later before an offline takeover, stop services on the application server, disconnect the application server and the heterogeneous storage system, use optical fibers or network cables to connect the host port on the application server and the service port on the local storage system, preventing services on the application server from being stopped multiple times.

    • When OceanStor UltraPath of which the version is V100R008C20 and later is installed on an application server, if the SN of the heterogeneous storage system version can be queried, you are advised to use the online takeover function of the local storage system to create eDevLUNs whose LUN masquerading type is Basic masquerading and use the eDevLUNs to take over external LUNs online. If the SN of the heterogeneous storage system version cannot be queried, you can use the online takeover function of the local storage system to create eDevLUNs whose LUN masquerading type is Extended masquerading and use the eDevLUNs to take over external LUNs online, or you can use the offline takeover function.
      Models and versions of storage systems whose SNs cannot be queried using UltraPath.
      • S2300E/S2600
      • S5300/S5500/S5600
      • Dorado2100
      • Versions earlier than Dorado5100 V100R001C00SPC800 (excluding V100R001C00SPCa00 and V100R001C00SPCb00)
      • Versions earlier than Dorado2100 G2 V100R001C00SPC500 (excluding V100R001C00SPCa00 and V100R001C00SPCb00)
      • Versions earlier than S2200T/S2600T/S5500T/S5600T/S5800T/S6800T V1R5C00SPC400
      • Versions earlier than S2200T/S2600T/S5500T/S5600T/S5800T/S6800T V1R5C01SPC100
NOTE:

For details about how to set parameters that are not mentioned in this section, see the related documents of the Huawei storage system.
