Dump a Non-Compute Node

Trigger an NCN memory dump and send the dump for analysis. This procedure is helpful for debugging NCN crashes.

A non-compute node (NCN) has crashed or an admin has triggered a node crash.

Force a dump on an NCN.
```
echo c > /proc/sysrq-trigger
```
Wait for the node to reboot.

The NCN dump is stored in /var/crash is on local disk after the node is rebooted.
Collect the dump data using the System Diagnostic Utility (SDU).

Refer to the "Run a Triage Collection with SDU" procedure in the SDU product stream documentation for more information about collecting dump data.

The --start_time command option can be customized. For example, "-1 day", "-2 hours", or a date/time string can be used. For more information on the SDU command options, use the sdu --help command.
```
sdu --scenario triage --start_time DATE_OR_TIME_STRING --end_time DATE_OR_TIME_STRING \
--plugin ncn.gather.nodes --plugin ncn.gather.kernel.dumps
```
Refer to the https://documentation.suse.com/ for more information on memory dumps or crash dumps.
