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).
|
|
|
|
The UCS drivers can use the Ironic Inspector service for in-band inspection of
|
|
equipment. For more information see the `Ironic Inspector documentation
|
|
<http://docs.openstack.org/developer/ironic-inspector/>`_.
|

|
Prerequisites
|
|
=============
|
|
|
|
* ``UcsSdk`` is a python package version of XML API sdk available to
|
|
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 ``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_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::
|
|
|
|
ironic node-create -d <pxe_ucs/agent_ucs> -i ucs_address=<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>
