Enabling and Disabling Automatic System Recovery

The ASR feature is not activated until you enable it. Enabling ASR requires changing configuration variables in ALOM as well as OpenBoot firmware.

▼To Enable Automatic System Recovery

1.At the sc> prompt, type:

sc> setsc diag_mode normal sc> setsc diag_level min

sc> setsc diag_trigger power-on-reset

2. At the ok prompt, type:

ok setenv auto-boot? true

ok setenv auto-boot-on-error? true

3.To cause the parameter changes to take effect, type:

ok reset-all

The system permanently stores the parameter changes and boots automatically when the OpenBoot configuration variable auto-boot?is set to true (its default value).

Note – To store parameter changes, you can also power cycle the system using the front panel Power button.
