Configuring a Routing Engine to Reboot or Halt 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 enable routers with a single Routing Engine (such as the M7i and M10i routers) to recover from this situation, you can configure the Routing Engine either to halt or to reboot when its hard disk fails. Include the disk-failure-action (halt | reboot) statement at the [edit chassis routing-engine on-disk-failure] hierarchy level:



[edit chassis routing-engine]

on-disk-failure {
disk-failure-action (halt | reboot);
}

Use halt to configure the Routing Engine to halt when the hard disk fails. Use reboot to configure the Routing Engine to reboot when the hard disk fails. For M7i and M10i routers, we recommend that you configure the Routing Engine to halt instead of rebooting when the hard disk fails.

You can also include the on-disk-failure statement on routers with dual Routing Engines, but we recommend that you configure the backup Routing Engine to assume mastership automatically when 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 High Availability Configuration Guide.
