Upgrade Using RPM Packages (KAE 1.0)

To upgrade KAE, run the rpm -Uvh command to install the new version. After the installation is complete, restart the system or manually uninstall the driver of the old version and reload the driver of the new version. This section describes upgrades within KAE 1.0 minor versions.

If KAE is installed using source code, skip this section because no upgrade is required.

Procedure

  1. Download the latest KAE software packages.
  2. Use an SSH tool to remotely log in to the Linux CLI as the root user.
  3. In the directory where the software packages are stored, upgrade the accelerator driver packages and engine library packages.
    1
    rpm -Uvh *.rpm
