Scanning for Hosts Running UltraPath

Specifying Whether to Use UltraPath on Your Host

This function requires Huawei's UltraPath multipathing software on the host side.

• To use Huawei UltraPath, enable the Use Ultrapath Host option. When this option is enabled:
  • The storage system automatically detects the hosts running UltraPath.
  • In the information display area, a simple wizard is displayed to guide you through system initialization.
• To use the multipathing software of the operating system, disable the Use Ultrapath Host option and exit the initialization wizard.

Configuring Storage Port

• If the storage system is connected to your host over a Fibre Channel network, skip Configure Storage Port and directly configure UltraPath on your host. For details, see Configuring UltraPath on Your Host.
• If the storage system is connected to your host over an iSCSI network, click the Configure button next to ETH.

  The Manage Logical Port page is displayed. You can create, modify, or delete a logical port, as well as manage route information.

  • To create a logical port:
    1. Click Create.

    3. Click OK.
  • To modify a logical port:
    1. Click More on the right of the desired logical port and select Modify.

       The Modify Logical Port page is displayed.

    2. Configure the logical port parameters. Table 2-9 describes the parameters.
       Table 2-9 Logical port parameters

       Parameter	Description
       Name	Name of the logical port. The name must meet the following requirements: The name must be unique. The name contains only letters, digits, periods (.), underscores (_), and hyphens (-). The name can contain 1 to 31 characters.
       IP Address Type	IP address type of the logical port. Possible values are IPv4 and IPv6.
       IP Address	IPv4 or IPv6 address of the logical port.
       Subnet Mask	Subnet mask of the logical port's IPv4 address. NOTE: This parameter is available only when IP Address Type is set to IPv4.
       Prefix	Prefix length of the logical port's IPv6 address. NOTE: This parameter is available only when IP Address Type is set to IPv6.
       Gateway	Gateway of the logical port's IP address.

    3. Click OK.
  • To manage routes:
    1. Select the desired logical port and click Manage Route.

       The Manage Route page is displayed.

       You can also click More on the right of the logical port and select Manage Route.

    2. In the IP Address drop-down list, select the IP address of the Ethernet port for which you want to add a route.
    3. Click Add.
    4. Set the parameters listed in Table 2-10.
       Table 2-10 Route parameters

       Parameter	Description
       Type	Three types of routes are available: Default route A route through which data is forwarded by default if no preferred route is available. The destination address and mask (IPv4) or prefix (IPv6) of the default route are automatically set to 0. To use this option, you only need to add a gateway. Host route A route to a host. The destination mask (IPv4) or prefix (IPv6) of the host route are automatically set to 255.255.255.255 or 128. To use this option, you only need to add the destination address and gateway. Network segment route A route to a network segment. You must add the destination address, destination mask (IPv4) or prefix (IPv6), and gateway.
       Destination Address	IPv4 address, IPv6 address, or network segment of the destination service network port on the application server or destination logical port on another storage system.
       Subnet Mask/Prefix	Subnet mask of the IPv4 address or prefix of the IPv6 address for the destination service network port on the application server or destination logical port on another storage system.
       Gateway	Gateway where the local logical port's IP address resides. NOTE: The IP address of the gateway must be different from all internal heartbeat IP addresses. Otherwise, routing will fail.

    5. Click . The route information is added to the list.

       To delete a route, select it and click .

    6. Click Close.
  • To delete a logical port:

    Select the desired logical port and click Delete.

    Confirm your operation as prompted.

    You can also click More on the right of the desired logical port and select Delete.

  After the configuration is complete, click Close.

Configuring UltraPath on Your Host

1. Configure connectivity between the storage system and your host. For details, see section "Configuring Connectivity" in the OceanStor Dorado Host Connectivity Guide for XXX. XXX represents a specific operating system, for example, Windows.
   • If the storage system is connected to your host over an iSCSI network, configure connectivity between the host initiator and the storage system.
   • If the storage system is connected to your host over a Fibre Channel network, query WWN information of the HBA on your host. If switches are used, categorize HBA ports on your host and ports on the storage system into zones based on the network planning.

2. Install UltraPath on your host in either of the following ways:
   • Installing UltraPath manually

     Follow instructions in the OceanStor UltraPath for XXX User Guide, where XXX indicates the operating system (for example, Windows).

   • Installing UltraPath using SmartKit
     Follow the instructions in Using SmartKit to Install UltraPath.

     • The Scan for Host function of the storage system is applicable only to Huawei UltraPath.
     • The UltraPath and SmartKit versions must match the storage system version. For details, refer to the version mapping table. To obtain the version mapping table, log in to https://support.huawei.com/enterprise/, enter your storage model in the search box, and select the associated path to the product documentation page. Then find and download the version mapping table.
     • When installing UltraPath manually, run the install.sh script on Linux.

3. Run the LUN scanning command on your host to ensure that the host information is registered on the storage system.
   • The purpose of this operation is to ensure that the host information is registered on the storage system but not to detect storage resources.
   • The LUN scanning mode varies according to the operating system. For common LUN scanning modes, see Common LUN Scanning Modes. For more details, see the OceanStor Dorado Host Connectivity Guide for XXX. XXX represents a specific operating system, for example, Windows.
   • If your host has not been mapped to a LUN, a 16 KB virtual disk will be displayed on your operating system. This virtual disk will disappear if you map your host to a LUN.

4. Select Installing UltraPath and scanning for LUNs are complete to continue with scanning of hosts running UltraPath.
