Operation Scenarios
This document describes how to adjust the CPU, memory, GPU, and other configuration specifications of an instance via the console, as well as related operational notes.
Prerequisites
Configuration adjustments are supported when the instance is either stopped or running. If the instance is running, the system will perform a forced shutdown, and the new configuration will take effect after the instance restarts.
Instance Status
