Servicing the CPU 2-3
Table 2-1 shows the permanent environment variables stored in EEPROM.
Some of these variables must be set when either adding a CPU or replac-
ing a broken one. You may view these variables by typing
show *
at the
console prompt.
Volatile environment variables are initialized by a system reset; others are
nonvolatile across system failures. Environment variables can be created
and modified using the
create
and
set
commands, respectively.
The form of the
set
command is
set <envar> <value>
and causes the
variable named to be changed in memory and in primary and secondary
EEPROMs. The change takes place immediately.
