bmcmanager is a tool for performing operations on rack units. It originated as a rackops fork, but has since been re-written almost from scratch, offering lots of additional functionality, bug-fixes and all-around improvements.

bmcmanager supports Lenovo, Dell and Fujitsu servers, and relies on NetBox for DCIM and IPAM. There is also expiremental support for MaaS.

bmcmanager is released under the terms of the GPL-3.0 license.

bmcmanager features include and are not limited to:

• Manage SEL and IPMI sensor readings.
• Get information for system RAM, disks, power status.
• IPMI management commands (power on, power off, power cycle, reset and more).
• Check for latest firmware versions and perform firmware upgrades.
• Nagios/Icinga compatible IPMI server checks (sensors, logs, disks, and more).
• Open console (requires JavaWS).
• Manage NetBox secrets.
• Configure unique IPMI credentials per server, store them as NetBox secrets and retrieve them automatically from NetBox.
• Bash auto-completion.
• Command output in multiple output formats (table, json, csv, value).
• (Expiremental) MaaS support. Match servers by hostname, and use MaaS IPMI credentials for all bmcmanager commands.

1. Install dependencies:

   # For Ubuntu/Debian
   $ sudo apt-get install freeipmi ipmitool icedtea-netx
   # For CentOS/Fedora
   $ sudo yum install freeipmi ipmitool icedtea-web

2. (Optional) Install osput for Lenovo firmware upgrades.

   # For CentOS/Fedora:
   $ wget https://download.lenovo.com/pccbbs/thinkservers/osput_1.3.2.zip
   $ unzip osput_1.3.2.zip
   $ yum install -y OSPUT-1.3.2/osput-1.3.2-1-rhel.x86_64.rpm

3. Install bmcmanager:

   $ pip install bmcmanager
   $ bmcmanager --help

1. You can install bmcmanager as a snap package:

   $ sudo snap install bmcmanager

Notes:

• The stable channel contains the latest stable release.
• The edge channel always contains the latest successful bmcmanager build from the master branch.
• The candidate channel contains the latest release candidate version.

Snap Limitations:

• The snap package is installed with strict confinement, so it is not allowed to read your files. If you want to use a config file, you need to put it under the SNAP_COMMON directory, which typically is /var/snap/bmcmanager/common.
• The snap package does not contain JavaWS, so opening a console is not possible.

1. Development and Release Docker images for bmcmanager are available at DockerHub:

   $ docker pull cloudeng/bmcmanager
   $ docker run --rm -it --entrypoint bash cloudeng/bmcmanager
   > bmcmanager --help

Docker Limitations:

• The docker image does not contain JavaWS, so opening a console is not possible.

bmcmanager uses a single configuration file. It looks in ~/.config/bmcmanager and $XDG_CONFIG_HOME/bmcmanager by default, but a different configuration file can be chosen by setting the --config-file command line argument.

The configuration file should have this form:

;; Configuration of "netbox" DCIM
[netbox]
; Required
api_url = <netbox_api_url>
; [Optional] Limit bmcmanager to query for certain device types only.
device_type_ids = <id1>, <id2>, ...
; Only if using NetBox secrets for IPMI credentials
netbox_token = <netbox_api_token>
session_key = <netbox_session_key>
; [Optional] Timeout when connecting to NetBox (in seconds).
timeout = 10

;; Configure of "maas" DCIM. Only required if using MaaS [Expiremental].
[maas]
; Required. Example: https://maas.internal.deployment:5240/MAAS/api/2.0
api_url = <maas_api_url>
; Required. Generate from MaaS GUI > User > API Keys > Generate MAAS API key.
; Example: AAAAAAAAAAA:BBBBBBBBBBBBBBB:CCCCCCCCCCCCCCCCC
api_key = <maas_api_key>
; Required for `bmcmanager open dcim` command. This is the root MaaS GUI URL.
; Example: https://maas.internal.deployment/
ui_url = <maas_ui_url>

;; Configuration of "lenovo" OOB
[lenovo]
; IPMI credentials
username = <username>
password = <password>

; Use secret with role <secret_role> as IPMI credentials. Secret name will
; be used as username, secret plaintext will be used as password. You need to
; set `netbox_token` and `session_key` above for this to work.
; If no secret is available, then `username` and `password` defined above will
; be used instead.
credentials = <secret_role>

; [optional] Configure NFS share and HTTP share (used by some commands)
nfs_share = "IP:/path/"
http_share = "http://IP/path/"

; [optional] Latest firmware versions to check against
; Used by the `bmcmanager firmware check` command
bios = <MAJOR.MINOR.PATCH>
tsm = <MAJOR.MINOR.PATCH>
psu_<model> = <MAJOR.MINOR.PATCH>

; [optional] Number of PSUs to expect per server
; Used by the `bmcmanager firmware check` command
expected_psus = 2

Some configuration can be overriden using environment variables:

• BMCMANAGER_USERNAME
• BMCMANAGER_PASSWORD
• BMCMANAGER_NFS_SHARE
• BMCMANAGER_HTTP_SHARE

• Retrieve the system event log for server lar0510:

  $ bmcmanager ipmi logs get lar0510
  $ bmcmanager ipmi logs get lar0510 --analysed    # Decode OEM fields

• Clear the system event log for server lar0510:

  $ bmcmanager ipmi logs clear lar0510

• Nagios check for IPMI sensor readings:

  $ bmcmanager ipmi sensor check lar0510

• Get information for disks attached to server:

  $ bmcmanager disks get lar0510

• Get latest firmware versions for thinkserver-rd550 servers, and download firmware bundles in /opt/firmware-bundles:

  $ bmcmanager firmware latest thinkserver-rd550 --download-to /opt/firmware-bundles

• Get firmware version for a server:

  $ bmcmanager firmware get lar0510
  $ bmcmanager firmware get lar0510 -f json

• Perform a BIOS firmware upgrade using the bios-v495.bdl file:

  $ bmcmanager firmware upgrade rpc lar0510 --bundle bios-v495.bdl

• Open JavaWS console:

  $ bmcmanager open console lar0510

• Power cycle server:

  $ bmcmanager power cycle lar0510

• Connect to BMC using SSH:

  $ bmcmanager ipmi ssh lar0510

• Change IPMI password and store in a NetBox secret with role MY_SECRET_ROLE. In the config file, set credentials = MY_SECRET_ROLE so that bmcmanager will use that automatically:

  $ export BMCMANAGER_USERNAME="DEFAULT_USER"
  $ export BMCMANAGER_PASSWORD="DEFAULT_PASS"
  $ bmcmanager ipmi credentials set lar0510 --new-password "NEW_PASSWORD" --secret-role "MY_SECRET_ROLE"
  $ bmcmanager ipmi credentials get lar0510

• Activate SOL for a MaaS host:

  $ bmcmanager ipmi tool --dcim maas HOSTNAME sol activate

Use bmcmanager --help for a list of available commands. Common command-line arguments for all supported commands are:

Most bmcmanager commands have the following format:

$ bmcmanager <command-name> <server-name>

bmcmanager searches NetBox using <server-name> as query string and executes the command for all matching devices.

The server selection arguments are:

Also use the --help flag to get more information for a particular command, e.g.:

$ bmcmanager ipmi logs get --help

NOTE: Auto-completion is enabled by default when using the snap package.

The bmcmanager complete generates a bash auto-completion script. You can use it directly:

$ . <(bmcmanager complete)
$ bmcmanager        # pressing tab should show available commands

Or add the auto-completion script under /etc/bash_completion.d/bmcmanager, so that it is loaded automatically by bash:

$ echo ". <($(which bmcmanager) complete)" | sudo tee /etc/bash_completion.d/bmcmanager
