Chapter 2: Accessing and Managing the System
The following example shows how to verify system recovery settings:
(SafeGuardOS) #show system recovery
Recovery Mode.................................. Fail-Passthru
Recovery State................................. N/A
(SafeGuardOS) #
In the above example, the system has been configured for “system recovery fail-
passthru”. N/A means there has not been a critical fault since the last reboot.
After a critical error has occurred, the output would look like this:
(SafeGuardOS) #show system recovery
Recovery Mode.................................. Fail-Passthru
Recovery State................................. Fail-Passthru on Dec 13 14:53:59
PST 2006
(SafeGuardOS) #
The Recovery State timestamps exactly when the system was put in fail-passthru mode.
Configuring Exception Recovery
Exception recovery is intended to allow the controller’s processor to survive certain kinds
of errors and keep processing. The user may enable the recovery feature and set the limits
before rebooting the unit as well as inspecting the state of recovery while viewing
statistics about its operation since reboot.
See the following sections for more details:
■ Enabling and Disabling Exception Recovery
■ Changing the Exception Recovery Parameters
■ Viewing the Exception Recovery Status
Enabling and Disabling Exception Recovery
To enable exception recovery, use the lsp recovery-mode command in Global
Configuration mode. To disable exception recovery, use the
no form of the command.
CAUTION: When the user logs into the system, a warning message is
displayed if the system is in Fail-PassThru mode. When system is in Fail-
PassThru mode, the user should not make any configuration changes because
some components are not operational.
In this state, user can use show commands for debugging and use the copy
command to transfer the core file and perform an upgrade. However, all other
commands are not disabled. Use any commands with extra caution.
