CIMC driver

CIMC driver

Overview

The cisco-ucs-standalone hardware type targets standalone Cisco UCS C series servers. It enables you to take advantage of CIMC by using the python SDK.

The CIMC hardware type can use the Ironic Inspector service for in-band inspection of equipment. For more information see the Ironic Inspector documentation.

Prerequisites

  • ImcSdk is a python SDK for the CIMC HTTP/HTTPS XML API used to control CIMC.

Install the ImcSdk module

Note

Install the ImcSdk module on the Ironic conductor node. Required version is 0.7.2.

  1. Install it:

    $ pip install "ImcSdk>=0.7.2"
    

Tested Platforms

This driver works with UCS C-Series servers and has been tested with:

  • UCS C240M3S

Configuring and Enabling the driver

  1. Add cisco-ucs-standalone to enabled_hardware_types in /etc/ironic/ironic.conf. For example:

    enabled_hardware_types = ipmi,cisco-ucs-standalone
    
  2. Restart the Ironic conductor service:

    For Ubuntu/Debian systems:

    $ sudo service ironic-conductor restart
    

    or for RHEL/CentOS/Fedora:

    $ sudo systemctl restart openstack-ironic-conductor
    

Registering CIMC Managed UCS node in Ironic

Nodes configured for CIMC driver should have the driver property set to cisco-ucs-standalone. The following configuration values are also required in driver_info:

  • cimc_address: IP address or hostname for CIMC

  • cimc_username: CIMC login user name

  • cimc_password: CIMC login password for the above CIMC user.

  • deploy_kernel: Identifier for the deployment kernel e.g. a Glance UUID

  • deploy_ramdisk: Identifier for the deployment ramdisk e.g. a Glance UUID

The following sequence of commands can be used to enroll a UCS Standalone node.

  • Create Node:

    openstack baremetal node create --driver cisco-ucs-standalone \
      --driver-info cimc_address=<CIMC hostname OR ip-address> \
      --driver-info cimc_username=<cimc_username> \
      --driver-info cimc_password=<cimc_password> \
      --driver-info deploy_kernel=<glance_uuid_of_deploy_kernel> \
      --driver-info deploy_ramdisk=<glance_uuid_of_deploy_ramdisk> \
      --property cpus=<number_of_cpus> \
      --property memory_mb=<memory_size_in_MB> \
      --property local_gb=<local_disk_size_in_GB> \
      --property cpu_arch=<cpu_arch>
    

    The above command ‘openstack baremetal node create’ will return UUID of the node, which is the value of $NODE in the following command.

  • Associate port with the node created:

    openstack baremetal port create --node $NODE <MAC_address_of_Ucs_server's_NIC>
