Handle hot upgrade failure on VMs

If hot upgrade fails on VMs, the dashboard will list those VMs in a dialog box after you log in. You can migrate, boot, shut down, and power off those VMs. If you perform one of these operations, the management platform will automatically upgrade the VMs to restore them.

Restrictions and guidelines

The management platform displays the hot upgrade failure prompt only upon your login after hot upgrade failure occurs. To view the prompt after login, click the icon in the top right corner. If the operator idle timeout is set to 0 second, the prompt will not appear after the Web interface is refreshed. To view the prompt, you must log in to the management platform again.
