Troubleshooting Solutions
Advanced Recovery Mode Tasks (Netconsole)
When necessary, you can perform more advanced tasks with the Recovery Mode
UI such as using Netconsole. Netconsole is a helpful tool for debugging kernel
issues where you need to capture and analyze kernel messages from a crashed or
hanging server when disk logging or serial consoles are unavailable.
When kernel boot messages need to be saved after a server crash/hang but access
to a serial console is not available, you can use the Netconsole tool to send boot
kernel printk messages to another host on the network using UDP packets.
Use the following procedure to perform Netconsole tasks using the AastraLink
Recovery Mode.
Note: You can contact Technical Support at any time, if necessary, by clicking on
the “Contact Support” link at the bottom right side of the Recovery Mode.
