Change a Variable Setting
Use this procedure to change an OpenBoot configuration variable setting.
 | Caution - Use extreme care when changing a configuration variable. An incorrect setting or typo can prevent the virtual machine from booting. |
Note - Many variable changes do not affect the operation of the firmware until the next power cycle or reset, at which time the firmware uses the new value of the variable.
- Access the OpenBoot CLI.
-
At the OpenBoot prompt, use this syntax:
{0} ok setenv variable-name valueWhere variable-name is the name of the variable and value is a numeric value or text string appropriate for the named variable. A numeric value is interpreted as a decimal number, unless preceded by 0x, which is the qualifier for a hexadecimal number.
For example, to set the auto-boot? variable to false, type:
{0} ok setenv auto-boot? false
