If you have installed RedHat Enterprise Linux 3.0 AS or ES Update 2 on the management server, you must also install the additional RPMs required by the N1 System Manager system.
Log in as root to the N1 System Manager management server.
Install the following RPMs from your RedHat installation CD-ROMs.
The location of the RPMs on the installation CD-ROMs varies depending on your RedHat Linux version.
A DSA signature:nokey warning is displayed during RPM installation. This warning message is generated only because the RPMs do not have a DSA security signature. All DSA signature:nokey warning messages can be safely ignored.
