Dear Lucas,
If information about the external LUN is not updated on the local storage system after operations on the heterogeneous storage system such as adding or deleting initiators or LUN mappings, or expanding external LUNs, manually scan the local storage system for LUNs.
Manually scan for LUNs using one of the following methods:
The operations in the following procedure are based on DeviceManager. For details about how to use scan remote_lun, see OceanStor 5300 V3&5500 V3&5600 V3&5800 V3&6800 V3 Storage System V300R003 command reference.
1. Log in to the DeviceManager for the local storage system.
2. Go to the Automatic LUN Scan dialog box.
On the navigation bar, click Data Protection. The Data Protection page is displayed.
In the left function pane, click Remote Device. The Remote Device page is displayed.
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.
Thank you!
