XPath OS 7.4.x administrator guide 17
High availability
XPath OS 7.4.x includes switch monitoring capabilities; this means that the MP Router monitors all critical
services. If any of these services fail, the router might reboot in order to preserve data and fabric integrity.
If you notice repeated reboots, issue the errShow command to determine the reason.
If the switch is unable to move into the service ready state within five minutes of rebooting, the MP
Router changes to the alternate bank and reboots again. The router is now set to disabled, to preserve the
integrity of the fabric. If the router is still not able to activate using the alternate bank, it reboots into the
recovery kernel.
To restore the MP Router to service, establish a telnet connection and issue the appropriate CLI command to
restore the service.
