CIMC drivers¶

Install the ImcSdk module¶

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 pxe_iscsi_cimc and/or pxe_agent_cimc to the list of enabled_drivers in /etc/ironic/ironic.conf. For example:

   enabled_drivers = pxe_ipmitool,pxe_iscsi_cimc,pxe_agent_cimc
   

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 pxe_iscsi_cimc or pxe_agent_cimc. 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:

ironic node-create -d <pxe_iscsi_cimc OR pxe_agent_cimc> -i cimc_address=<CIMC hostname OR ip-address> -i cimc_username=<cimc_username> -i cimc_password=<cimc_password> -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>
