Update RPMs and SMUs
An RPM may contain a fix for a specific defect, and you may need to update the system with that fix. To update RPMs and SMUs to a newer version, use the install update command. When the install update command is issued for a particular RPM, the router communicates with the repository, and downloads and activates that RPM. If the repository contains a dependent RPM, the router identifies that dependent RPM and installs that too.
The syntax of the install update command is:
install update source repository [rpm]
Four scenarios in which you can use the install update command are:
When a package name is not specified
When no package is specified, the command updates the latest SMUs of all installed packages.
install update source [repository]
When a package name is specified
If the package name is specified, the command installs that package, updates the latest SMUs of that package, along with its dependencies. If the package is already installed, only the SMUs of that package are installed. (SMUs that are already installed are skipped.)
When a package name and version number are specified
If a particular version of package needs to be installed, the complete package name must be specified; that package is installed along with the latest SMUs of that package present in the repository.
When an SMU is specified
If an SMU is specified, that SMU is downloaded and installed, along with its dependent SMUs.
