Changing Node Class

Precautions

• Change node class during off-peak hours because services will be interrupted for a while during class changing.
• After a read-only group is created, the entry for changing node class will be moved to the operation column of the group.
• Once the change operation is performed, it cannot be undone. To change the class again, submit another request after the change is complete.
• Node class can be upgraded or downgraded.

Procedure

1. Log in to the DDM console.
2. On the Instances page, locate the instance whose node class you want to change and click its name.
3. Click Change. If a group is created, click Change Node Class in the Operation column in the Group Information area.
4. On the displayed page, select the required class.
5. Confirm the configurations and click Submit.
6. Switch back to the instance list and check whether the instance status changes to Changing class. You can also view the change task at Task Center.
