This property specifies the action to be taken when the boot timer expires.
Following are the acceptable values for this property:
Iif you enter any value other than those listed above, the software automatically defaults to xir.
Note: If you set the ntwdt-bootrestart property to xir, you must also set the OpenBoot PROM NVRAM variable auto-boot-on-error? to true and the error-reset-recovery variable to boot. In addition, for this option to work reliably, the system must reboot followed by an xir, which may not happen in all cases (for example, if the system fails to find the boot disk and drops down to the ok prompt). Because of these restrictions, you may want to set the ntwdt-bootrestart property to reset for a more consistent behavior.
