[Huawei Storage Documentation-FAQs]How To Do If Controller Expansion Fails For the Process Lasts Over 24h After the Controller to Be Added Is PowerOn?

Question:

What can I do if controller expansion fails because the process lasts for over 24 hours after the controllers to be added are powered on?

Solution:

If a controller expansion lasts for over 24 hours after the controllers to be added are powered on, the AD process in the storage system will be disabled. As a result, controllers in the cluster cannot communicate with each other, leading to a controller expansion failure. You can enable the AD process as follows:

1. Log in to the CLI of each controller to be added.

2. Run change user_mode current_mode user_mode=engineer to enter the engineer view.

3. Run change ad_process action=startup to enable the AD process.

4. Run show ad_process status to check whether AD Node is Online. If AD Node is Online, the AD process has been enabled.
