Environment Variable Summary
Environment variables pass configuration information between the console
and the operating system. Their settings determine how the system powers up,
boots the operating system, and operates. Environment variables are set or
changed with the set envar command and returned to their default values with
the clear envar command. Their values are viewed with the show envar
command. The environment variables are specific to the SRM console. Table
11-6 lists the environment variables. Detailed descriptions follow.
