Configuring Hardware Recovery--SummitStack and Summit Family Switches Only

You can configure Summit family switches or SummitStack to take no action, automatically reboot, or shut down if the switch detects a hardware fault.

Configure how the switch recovers from hardware problems on a stand-alone Summit family switch with the command:
configure sys-recovery-level switch [none | reset | shutdown]
Configure hardware recovery on a particular active node in the SummitStack with the command:
configure sys-recovery-level slot [all | slot_number] [none | reset | shutdown]
Where the following is true:
- none—Configures the switch to maintain its current state regardless of the detected fault. The switch does not reboot or shut down. ExtremeXOS software logs fault and error messages to the syslog.
- reset—Configures the switch to reboot upon detecting a hardware fault. ExtremeXOS software logs fault, error, system reset, and system reboot messages to the syslog.
- shutdown—Configures the switch to shut down upon detecting a hardware fault. All ports are taken offline in response to the reported errors; however, the management port remains operational for debugging purposes only. If the switch shuts down, it remains in this state across additional reboots or power cycles until you explicitly clear the shutdown state. See Clearing the Shutdown State for more information. ExtremeXOS logs fault, error, system reset, system reboot, and system shutdown messages to the syslog.
The default setting is reset.

You can configure how ExtremeXOS handles a detected fault depending on the sys-recovery-level setting. To configure how ExtremeXOS handles faults, use the configure sys-health-check all level [normal | strict] command. For detailed information about this command, see the appropriate ExtremeXOS User Guide volume.
To view the system health check settings on the switch, use the show switch command as described in Displaying the System Health Check Setting--All Platforms.
