NETGEAR 8800 User Manual Note: When the sys-recovery-level is set to none, running msm-failover does not reboot the current MSM. • reset-Configures the offending MSM/MM or I/O module to reset upon fault detection. XCM8800 logs fault, error, system reset, and system reboot messages to the syslog. • shutdown-Configures the switch to shut down all slots/modules configured for shutdown upon fault detection. On the modules configured for shutdown, all ports in the slot are taken offline in response to the reported errors; however, the MSMs/MMs remain operational for debugging purposes only. You must save the configuration, using the save configuration command, for it to take effect. XCM8800 logs fault, error, system reset, system reboot, and system shutdown messages to the syslog. The default setting is reset. Depending on your configuration, the switch resets the offending MSM/MM or I/O module if a hardware fault detection occurs. An offending MSM/MM is reset any number of times and is not permanently taken offline. On NETGEAR 8800 series switches, an offending I/O module is reset a maximum of five times. After the maximum number of resets, the I/O module is permanently taken offline. For more information, see Module Recovery Actions on page 208. You can configure how XCM8800 handles a detected fault based on the configuration of the configure sys-recovery-level slot [all | ] [none | reset | shutdown] command. To configure how XCM8800 handles faults, use the configure sys-health-check all level [normal | strict] command. For detailed information about this command, see the NETGEAR 8800 Chassis Switch CLI Manual. To view the system health check settings on the switch, use the show switch command as described in Displaying the System Health Check Setting on page 203. Confirmation Messages Displayed If you configure the hardware recovery setting to either none (ignore) or shutdown, the switch prompts you to confirm this action. The following is a sample shutdown message: Are you sure you want to shutdown on errors? (y/n) Enter y to confirm this action and configure the hardware recovery level. Enter n or press [Enter] to cancel this action. Understanding the Shut Down Recovery Mode You can configure the switch to shut down one or more I/O modules upon fault detection by specifying the shutdown option. If you configure one or more slots to shut down and the switch detects a hardware fault, all ports in all of the configured shut down slots are taken offline in response to the reported errors. (MSMs/MMs are available for debugging purposes only.) The affected I/O module remains in the shutdown state across additional reboots or power cycles until you explicitly clear the shutdown state. If a module enters the shutdown state, the module actually reboots and the show slot command displays the state of the slot as Chapter 8. Status Monitoring and Statistics | 207
