Licensing Method

ZStack Cloud supports two licensing methods: USB key and request key.
  • Licensing by USB Key
    • You can obtain the authorization by inserting only one USB key into the management node.
    • If you are using a dual-MN environment, insert only one USB key.
    • The Plus licenses authorized by an USB Key cannot be deleted.
  • Licensing by Request Key
    • You can obtain the authorization by uploading the license file to the management node.
    • You can upload both the Base license and Plus license at the same time by using a tar.gz package.
    • If you are using a dual-MN environment, we recommend that you upload the license file on the management node where the virtual IP address is located.

Install a License

The admin can install a license by using a USB key or a request key. These two methods are detailed in the following topics.


Install a License by Using a USB Key

This topic focuses on the method of getting a license by using a USB key, including installing a license by using a USB key, renewing a license by using a USB key, and viewing the status of a USB key.

Install a License by Using a USB Key

To install a license by using a USB key, the admin can follow these steps:
  1. Insert the USB key into the management node.
  2. On the main menu of ZStack Cloud, choose Personal Center > License Management. Then, the License Management page is displayed.
  3. On the License Management page, click the Refresh button to the left of Upload License.
    Figure 1. Refresh License


  4. Then, you can see the whole licensing information.
    Figure 2. Whole Licensing Information


Note:
  • If you have got a license by using a request key, you can view Plus License of both the request key and USB key after inserting the USB key. If the Plus License is the same, the latest uploaded one will be taken as a reference.
  • If you get a license by using the USB key, every time you enter the License Management interface of the Cloud, there will be about two seconds of information reading, and the relevant information of the USB key will appear after two seconds.
  • If you are using a dual-MN environment, note that:
    • You can obtain the authorization by inserting only one USB key into the management node.
    • If the node with the USB key inserted is faulty, we recommend that you remove the USB key and insert it into another healthy node to ensure the business continuity.
    • If you update from a single management node environment to a dual-MN environment, you do not need to get the additional license.

Renew a License by Using a USB Key

To resize or add licenses after uploading the license, the admin can follow these steps to renew the license by using a USB key:
  1. Insert the USB key into the management node.
  2. On the main menu of ZStack Cloud, choose Personal Center > License Management. Then, the License Management page is displayed.
  3. On the License Management page, click the Copy button to the right of the Key ID.
    Figure 3. Copy Key ID


  4. Apply for a license by using the USB Key ID to get the licensing file.
  5. Go back to the License Management page, Click Upload License to upload the licensing file.
    Figure 4. Upload License


  6. Check whether the licensing information is correct.
Note:
  • If you do not insert a USB key into the management node, you can not upload a license by using the USB key.
  • If the USB key ID dose not match the applied license, you can not upload the license by using the USB key.
  • If you apply a new license by using a USB key, you need to fill in previous all applied information and then add new Plus License information when the USB key does not match the request key.

View USB Key Status

On the main menu of ZStack Cloud, choose Personal Center > License Management. Then, the License Management page is displayed. You can view the current status of the USB key of the Cloud.

Figure 5. View USB Key Status


USB Key Status

USB key has the following statuses.
Status Description
Ready The USB key is Ready when there is only one USB key inserted into the management node and it works properly.
Missing After unplugging the USB key, the USB key is Missing.
Note: When unplugging the USB key, the Cloud will check whether the current license is expired.
  • If it is expired, there will be no buffer license after unplugging the USB Key. It keeps the status of Expired.
  • If it is not expired,
    • a 30-day buffer license is generated based on the current license of the USB key when you unplug the USB key at the first time.
    • the last time it was unplugged will be detected when you do not unplug the USB key for the first time:
      • If the period between two times is 60 days or more, the buffer license is renewed.
      • If the period is less than 60 days, the expiration time of the previous buffer license is retained.
    • After unplugging the USB key and inserting a new USB key, the licensing information of the new USB key will be displayed and the buffer license of the old USB key will be invalidated.
Abnormal For a dual-MN environment, you might face a possibility of USB key failure if you:
  • Insert one USB key into each of the two management nodes.
  • Insert one USB key into one management node, and insert multiple USB keys into the other management node.
Note: The USB key in an abnormal state does not affect the license.
Fault
  • For a dual-MN environment, you may face a possibility of USB key failure if you:
    • Insert multiple USB keys into one management node, and insert no USB key into the other management node.
    • Insert multiple USB keys into every management node.
  • For a single management node environment, if you insert multiple USB keys into this management node, the USB key status will be Faulty.
Note: When the USB key status is Faulty, you can not use the license after the buffer license is expired.
