3.6 Using the SRM Console
Several SRM commands can be used to set the system environment,
power CPUs on and off, display configuration information, display
error information, and test and exercise the system.
3.6.1 Displaying and Setting Up the System Environment
Several SRM console commands are used to display and set system
environment variables stored in EEPROM on the standard I/O module.
Example 3– 14 Set Environment Variables
P00>>> set console serial
P00>>>
Example 3–14 shows an example of the set environment variable command (set
<envar>). Environment variables pass configuration information between the console
and the operating system. Settings determine how the system is configured, how it
powers up, and boots. This particular variable controls the protocol used by the console.
Note: Environment variables must be defined separately in each partition.
Example 3– 15 Show Environment Variables
P00>>> show console
Console serial
P00>>>
Example 3–15 shows an example of the show environment variable command (show
<envar>). You can show all environment variables by using the show * command.
Example 3– 16 Clear Environment Variables
P00>>> clear console
P00>>>
Example 3–16 shows an example of the clear environment variable command (clear
<envar>). The command clears the variable.
For a complete description of environment variables, see the AlphaServer GS80/160/320
User’s Guide or the AlphaServer GS80/160/320 Firmware Reference Manual.
