Configuring the Junos OS to Enable a Routing Engine to Reboot on Hard Disk Errors
When a hard disk error occurs, a Routing Engine might enter a state in which it responds to local pings and interfaces remain up, but no other processes are responding.
To recover from this situation, you can configure a single Routing Engine to reboot automatically when a hard disk error occurs. To enable this feature, include the on-disk-failure reboot statement at the [edit chassis routing-engine] hierarchy level.
For dual Routing Engine environments, you can configure a backup Routing Engine to assume mastership automatically, if it detects a hard disk error on the master Routing Engine. To enable this feature, include the on-disk-failure statement at the [edit chassis redundancy failover] hierarchy level. For information about this statement, see the Junos OS High Availability Configuration Guide.
You can configure the Routing Engine to halt (instead of rebooting) when the hard disk fails on the Routing Engine. To configure this feature, include the disk-failure-action (halt | reboot) statement at the [edit chassis routing-engine on-disk-failure] hierarchy level:
Use the halt option to configure the Routing Engine to halt when the hard disk fails. Use the reboot option to configure the Routing Engine to reboot when the hard disk fails.
