BMC and BlueField Logs

The BMC and BlueField-2 logs can be collected using openbmctool as BMC and system dump.

Two types of dump are supported:

BMC dump, which is a collection of logs from BMC
System dump, which is a collection of logs from BlueField-2. To create a system dump, users must provide the BlueField-2 credentials and IP address of the tmfifo_net0 network interface.

BMC Dump Operations

The following table lists BMC dump operations:

Operation	Command	Description
Create BMC dump	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump create` Where: `-H` – Host IP `-U` – Username `-P` – Password `dump create` – command to create BMC dump	Creates a BMC dump and stores the tar on BMC
List BMC dumps	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump list` Where: `dump list` – command to list created dumps	Lists all BMC dumps existing on BMC
Download BMC dump	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump retrieve -n 1` Where: `dump retrieve` – command to download a dump `-n 1` – dump ID	Downloads the user-specified BMC dump
Delete BMC dump	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump delete -n 2` Where: `dump delete` – command to delete a dump `-n 2` – dump ID	Deletes the user-specified dump on BMC

System Dump Operations

The following table lists system dump operations:

Operation	Command	Description
Create system dump	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump -t SystemDump create -a '{"bf_ip":"<bf2_tmfifo_ip_address>","bf_username":"<bf2_username>","bf_password":"<bf2_password>"}'` Where: `-H` – Host IP `-U` – Username `-P` – Password -t – DumpType create – command to create system dump `-a` – additional arguments for BlueField-2. A (key,value) pair list of arguments for BlueField-2 tmfifo IP address and credentials.	Creates a system dump and stores the tar on the BMC
List system dumps	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump -t SystemDump list` Where: `dump list` – command to list created dumps	Lists all system dumps existing on BMC
Download system dump	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump -t SystemDump retrieve -n 1` Where: `dump retrieve` – command to download a dump `-n 1` – dump ID	Downloads the user-specified system dump
Delete system dump	Copy Copied! `python3 openbmctool.py -H <ip_address> -U <username> -P <password> dump -t SystemDump delete -n 2` Where: `dump delete` – command to delete a dump `-n 2` – dump ID	Deletes the user-specified system dump on BMC

The downloaded dump tar must be extracted to get the logs for BMC or BlueField-2.

Upon creating a dump, please allow the system ~5 mins to prepare the dump. The created dump will appear on the dump list when the system finishes dump creation. The created dump can be downloaded from the BMC using the retrieve command.
