Automatically Scanning for a Host

Automatically Scanning for a Host

This operation enables you to trigger automatic scanning of hosts. The discovered hosts are automatically added to the host list.


  • The multipathing software provided by the storage manufacturer has been installed on hosts. OS native multipathing software is not supported.
  • In an iSCSI networking environment, initiators have been configured for hosts to connect to the storage system.
  • In an FC networking environment, the host's HBA port and the storage system's port are in the same zone.


By default, automatic host scan is not enabled. If no hosts are found after the scan is complete, scan for disks on application servers and retry.


  1. Choose Provisioning > Host.
  2. (Optional) Enable automatic host scan.

    • If automatic host scan is enabled, skip this step.
    • If the storage system automatically detects a host initiator and the initiator has not been added to any host, a 16 KB virtual disk is displayed on the host operating system. After the initiator is added to a host, the virtual disk disappears.
    1. Click Parameter Settings.

      The Set Automatic Scan dialog box is displayed.

    2. Select Enable and click OK.

      The Execution Result dialog box is displayed, indicating that the operation is successful.

    3. Click OK.

  3. Choose Create > Automatic Scan.

    The Confirm dialog box is displayed.

  4. Click OK.

    The system starts scanning for hosts. Detected hosts will be added to the host list.

  5. Click Close.


    If the automatic host scanning function is enabled, a Confirm dialog box is displayed each time you access the Host page. You need to confirm whether to immediately perform automatic host scanning in the dialog box.
