UCS drivers

Overview

The UCS driver is targeted for UCS Manager managed Cisco UCS B/C series servers. The pxe_ucs, agent_ucs drivers enables you to take advantage of UCS Manager by using the python SDK.

pxe_ucs driver uses PXE/iSCSI (just like pxe_ipmitool driver) to deploy the image and uses UCS to do all management operations on the baremetal node (instead of using IPMI).

agent_ucs driver uses IPA ramdisk (just like agent_ipmitool and agent_ipminative drivers.) to deploy the image and uses UCS to do all management operations on the baremetal node (instead of using IPMI).

Prerequisites

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

    Install UcsSdk1 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 pxe_ucs and/or agent_ucs to the list of enabled_drivers in /etc/ironic/ironic.conf. For example:

    enabled_drivers = pxe_ipmitool,pxe_ucs,agent_ucs

  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 pxe_ucs/agent_ucs. The following configuration values are also required in driver_info:

  • ucs_hostname: 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:

ironic node-create -d <pxe_ucs/agent_ucs> -i ucs_hostname=<UCS Manager hostname/ip-address> -i ucs_username=<ucsm_username> -i ucs_password=<ucsm_password> -i ucs_service_profile=<serivce_profile_dn_being_enrolled> -i deploy_kernel=<glance_uuid_of_deploy_kernel> -i deploy_ramdisk=<glance_uuid_of_deploy_ramdisk> -p cpus=<number_of_cpus> -p memory_mb=<memory_size_in_MB> -p local_gb=<local_disk_size_in_GB> -p cpu_arch=<cpu_arch>

The above command 'ironic node-create' will return UUID of the node, which is the value of $NODE in the following command.

Associate port with the node created:

ironic port-create -n $NODE -a <MAC_address_of_Ucs_server's_NIC>
