Overview
OSMT is a tool provided by Huawei Cloud to upgrade or roll back HCE and RPM packages. It also allows you to customize the upgrade scope, configure scheduled checks, perform a single upgrade at the specified time period, and schedule restarts for RPM packages.
- To upgrade or roll back HCE, see Version Upgrade and Rollback.
- To update or roll back only RPM packages, see Updating RPM Packages.
OSMT can only upgrade or roll back HCE 2.0 or later. This tool periodically accesses the repository to obtain software update information, which will generate network traffic. You can run the systemctl stop osmt-agent command to stop this tool and run the systemctl disable osmt-agent command to disable automatic startup of this tool.
