Patch installation may involve potential risks such as service interruptions, CPU spikes, and I/O spikes, which can affect normal business operations. Perform patch installation during an appropriate period, such as off-peak hours. Risks include:

ECS instance restart is required after kernel patch installation, which directly interrupts services on the deployment node.

Operations such as file decompression, signature verification and system file replacement during patch installation can easily cause CPU and I/O resource contention. This impairs business performance and causes application crashes and other issues. This process may also consume a large amount of network bandwidth, affecting cross-node service communication.

Procedure

In the left-side navigation pane, select "Maintenance & Monitoring > Patch Management".

In the top menu bar, select the region where your business is located.

On the Patch management page, click the "Patch plan" tab.

In the "Actions" column of the target patch plan, click the "Clone" button.

(Optional) Modify the parameters based on your business requirements. For more information, see Creating patch plans.

Click the "Clone" button to complete the operation.

After the patch plan task is cloned, it will start executing based on the selected execution mode.
