If you need to perform maintenance operations on a cloud computer and do not want end users to connect to and use the cloud computer when you maintain the cloud computer, you can switch the cloud computer to maintenance mode. This topic describes how to put cloud computers into maintenance mode.
Background
To install or uninstall configuration files or applications and manage the configurations of the system disk on a cloud computer, you must first put the cloud computer into maintenance mode. The following items describe the maintenance mode:
If you put a cloud computer that is not assigned to end users into maintenance mode, you cannot click View/Assign Users or Manage User MFA Device in the Actions column of the cloud computer.
If you put a cloud computer that is assigned to end users into maintenance mode, the cloud computer enters the Under Maintenance state as soon as all end users disconnect from the cloud computer. The end users cannot reconnect to the cloud computer until the cloud computer exits maintenance mode.
If you put a cloud computer that is assigned to end users and contained in a cloud computer pool into maintenance mode, the cloud computer enters the Under Maintenance state only after all sessions of the cloud computer are disconnected. The cloud computer is temporarily unavailable for assignment. When an end user requests a cloud computer, the system checks whether idle cloud computers exist based on the cloud computer scaling rules that you configured. If idle cloud computers exist, the system randomly assigns one of the idle cloud computers to the end user.
The system records maintenance operations on a cloud computer in the Under Maintenance state. You can view operation logs after your Alibaba Cloud account is attached the required system policy. For more information, see Attach a WUYING Workspace system policy to a RAM user or View administrator operation logs.
Prerequisites
The cloud computer is in the Stopped or Running state.
If you use a RAM user to maintain the cloud computer, you are granted the required permissions on the cloud computer. For more information, see Grant permissions to a RAM user.
