What Can I Do After the Heterogeneous Storage System Restarts, the Local Storage System Cannot Display the Remote LUN That Corresponds to the External LUN or the eDevLUN Fails?

Question

What can I do after the heterogeneous storage system restarts, the local storage system cannot display the remote LUN that corresponds to the external LUN or the eDevLUN fails?

Answer

If the local storage system has either of the following issues after the heterogeneous storage system restarts, scan for LUNs manually:
  • The local storage system cannot display the remote LUN that corresponds to the external LUN.
  • The eDevLUN for the external LUN fails.
Manually scan for LUNs using one of the following methods:
  • Start an automatic LUN scan in DeviceManager.
  • In CLI, run the scan remote_luncommand.
NOTE:

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. Go to the Automatic LUN Scan dialog box.
    1. On the navigation bar, click .

      The Data Protection page is displayed.

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

      The Remote Device page is displayed.

    3. 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.

  3. Click OK to start an automatic LUN scan.

    DeviceManager then scans for LUNs, and synchronizes the configuration of the remote LUN with that of the external LUN and updates the number of remote LUNs.

  4. Click Close.
