Collect ThinkSystem DM BMC Logs After a Node Failure
For an unexplained ThinkSystem DM node shutdown or restart, Lenovo Support may request BMC logs. This is initial diagnostic collection; more data may be needed. A powered and reachable BMC can remain accessible over SSH even when the node operating system is down.
Record the session
Enable session logging before collecting output. The original PuTTY example selects All session output and a local log file:

Find and connect to the BMC
Connect over SSH to the affected node’s BMC management address:
If the address is unknown, connect to the ONTAP cluster management IP and run:
system service-processor show
Collect the requested diagnostic output
At the BMC prompt, run the following commands as directed by Lenovo Support and retain their output in the session log:
| Command | Purpose |
|---|---|
priv set diag | Enter diagnostic user mode |
events all | Print all system events |
system log | Print system console logs |
bmc status -d | Print BMC debug information |
bmc diag | Run BMC diagnostics |
