How Can I Discover a Remote LUN Belonging to a Heterogeneous Storage System in a Local Storage System After the LUN Is Mapped to the Local Storage System for Hosting but the LUN Is Not Yet Initialized?

Question

How can I discover a remote LUN belonging to a heterogeneous storage system in a local storage system after the LUN is mapped to the local storage system for hosting but the LUN is not yet initialized?

Answer

  1. Wait until the LUN is initialized on the heterogeneous storage system.
  2. Manually scan for LUNs on the local storage system.

    NOTE:
    Use one of the following methods to scan for LUNs:
    • Start an automatic LUN scan in DeviceManager.
    • In CLI, run the scan remote_lun command.

    The operations in the following procedure are based on DeviceManager. For details about how to use scan remote_lun, see OceanStor 2200 V3&2600 V3 Storage System V300R005 Command Reference .

    1. Log in to the DeviceManager for the local storage system.
    2. On the navigation bar, click Data Protection.

      The Data Protection page is displayed.

    3. In the left function pane, click Remote Device.

      The Remote Device page is displayed.

    4. Based on Name and SN, select the remote device that corresponds to the heterogeneous storage system. In the lower function pane, click Automatic Scan.

      The OK dialog box is displayed.

    5. Click OK to start an automatic LUN scan.

      After the automatic scan is completed, the remote LUN configurations on the local storage system are updated, and the quantity of remote LUNs is changed.
