UCS driver

UCS driver

Overview

The UCS driver is targeted for UCS Manager managed Cisco UCS B/C series servers. The cisco-ucs-managed hardware type enables you to take advantage of UCS Manager by using the python SDK.

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

Prerequisites

  • UcsSdk is a python package version of XML API sdk available to manage Cisco UCS Managed B/C-series servers.

    Install UcsSdk 1 module on the Ironic conductor node. Required version is 0.8.2.2:

    $ pip install "UcsSdk==0.8.2.2"
    

Tested Platforms

This driver works on Cisco UCS Manager Managed B/C-series servers. It has been tested with the following servers:

UCS Manager version: 2.2(1b), 2.2(3d).

  • UCS B22M, B200M3

  • UCS C220M3.

All the Cisco UCS B/C-series servers managed by UCSM 2.1 or later are supported by this driver.

Configuring and Enabling the driver

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

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

    service ironic-conductor restart
    

Registering UCS node in Ironic

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

  • ucs_address: IP address or hostname of the UCS Manager

  • ucs_username: UCS Manager login user name with administrator or

    server_profile privileges.

  • ucs_password: UCS Manager login password for the above UCS Manager user.

  • deploy_kernel: The Glance UUID of the deployment kernel.

  • deploy_ramdisk: The Glance UUID of the deployment ramdisk.

  • ucs_service_profile: Distinguished name(DN) of service_profile being enrolled.

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

  • Create Node:

    openstack baremetal node create --driver cisco-ucs-managed \
        --driver-info ucs_address=<UCS Manager hostname/ip-address> \
        --driver-info ucs_username=<ucsm_username> \
        --driver-info ucs_password=<ucsm_password> \
        --driver-info ucs_service_profile=<service_profile_dn_being_enrolled> \
        --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>
