| + | **To check this out do the following: | ||
| + | |||
| + | 1. start shell | ||
| + | 2. sysctl machdep.bootdevs | ||
| + | |||
| + | This second command will tell you the order in which devices are booted from. If ‘disk’ is absent from that list, you need to add it back in and reboot the routing-engine. Do the following: | ||
| + | |||
| + | su root (you’ll need the root password for this) | ||
| + | | ||
| + | Exit from the shell and reboot the RE. | ||
| + | |||
| + | The above is for an MX960 with an RE-2000 installed, and the device names change a bit depending on what you are using. Best to check it against another working system if you can. | ||
| + | |||
| + | Here’s a cut-and-paste from my MX960: | ||
| + | < | ||
| + | root@MX960-RE1% sysctl machdep.bootdevs | ||
| + | machdep.bootdevs: | ||
| + | root@MX960-RE1% sysctl -w machdep.bootdevs=usb, | ||
| + | machdep.bootdevs: | ||
| + | root@MX960-RE1% exit | ||
| + | exit | ||
| + | % sysctl machdep.bootdevs | ||
| + | machdep.bootdevs: | ||
| + | % exit | ||
| + | </ | ||
