Checking License Files

eReplication adopts many value-added features of Huawei storage, ensuring data consistency along with the DR process. To use these features, you need to obtain and import the license files of them and eReplication.

Context

Without importing a license, you can use all DR services for the first 90 days. After that, you can only use functions provided by the basic edition.
If the synchronous replication (SAN) is used for DR protection or recovery, licenses for array-based remote replication and array snapshot must be imported to the storage device.
When you perform a DR test, eReplication needs to use the array snapshot feature to create snapshots at the DR site. Therefore, the license for array snapshot must be imported.

Procedure

Based on the DR technology you use, check whether required licenses (for array-based remote replication, array snapshot, or HyperVault) are imported to the storage devices.
The following operation introduces how to check license files using OceanStor 18500 V5 as an example.
1. Log in to OceanStor DeviceManager.
2. In the navigation tree on the right, click Setting.
3. In the Basic Service Settings area, click License Management.
  The License Management page is displayed.
4. In the navigation tree on the left, choose Activate License.
  In the information display area on the middle, view information about the activated license files to ensure whether licenses for remote replication, snapshot, or HyperVault are included.
  
  If no license is available, purchase and import a license file. For details, see the license application guide corresponding to the storage device.
Check the licenses for eReplication.
1. Log in to eReplication as a user with management permissions.
2. On the menu bar, choose Settings.
3. In the navigation tree, choose License.
4. In the information display area on the middle, view information about license files to check whether the license files are imported.
  - If yes, no further action is required.
  - If no, go to 2.e.
5. Click Import and select license files to be activated.
  The system automatically checks the format and content of license files. If the check passes, the system automatically activates the imported licenses.
  
  For details about how to apply for licenses, see the OceanStor BCManager 8.5.0 eReplication License Application Guide(Traditional Disaster Recovery).
6. After the license files are imported, check whether they are what you apply for.
7. Optional: Click Export. You can save the license files locally for easy backup.
