This patch adds a section about creating a deploy ramdisk with IPA instead of the bash ramdisk and also update the driver specific documentations to point to it when creating a deploy image. Implements: blueprint deprecate-bash-ramdisk Change-Id: Id9d86cafc35efdbec2d53b7c956a94d39f205e41

SeaMicro driver
Overview
The SeaMicro power driver enables you to take advantage of power cycle management of servers (nodes) within the SeaMicro chassis. The SeaMicro driver is targeted for SeaMicro Fabric Compute systems.
Prerequisites
python-seamicroclient
is a python package which contains a set of modules for managing SeaMicro Fabric Compute systems.Install
python-seamicroclient
1 module on the Ironic conductor node. Minimum version required is 0.4.0.:$ pip install "python-seamicroclient>=0.4.0"
Drivers
pxe_seamicro driver
Overview
pxe_seamicro
driver uses PXE/iSCSI (just like
pxe_ipmitool
driver) to deploy the image and uses SeaMicro
to do all management operations on the baremetal node (instead of using
IPMI).
Target Users
- Users who want to use PXE/iSCSI for deployment in their environment.
- Users who want to use SeaMicro Fabric Compute systems.
Tested Platforms
This driver works on SeaMicro Fabric Compute system. It has been tested with the following servers:
- SeaMicro SM15000-XN
- SeaMicro SM15000-OP
Requirements
None.
Configuring and Enabling the driver
Build or download a deploy image, see
BuildingDeployRamdisk
Upload these images to Glance:
glance image-create --name deploy-ramdisk.kernel --disk-format aki --container-format aki < deploy-ramdisk.kernel glance image-create --name deploy-ramdisk.initramfs --disk-format ari --container-format ari < deploy-ramdisk.initramfs
Add
pxe_seamicro
to the list ofenabled_drivers
in/etc/ironic/ironic.conf
. For example:enabled_drivers = pxe_ipmitool,pxe_seamicro
Restart the Ironic conductor service:
service ironic-conductor restart
Registering SeaMicro node in Ironic
Nodes configured for SeaMicro driver should have the
driver
property set to pxe_seamicro
. The
following configuration values are also required in
driver_info
:
seamicro_api_endpoint
: IP address or hostname of the SeaMicro with valid URL as http://<IP_address/hostname>/v2.0seamicro_server_id
: SeaMicro Server ID. Expected format is <int>/<int>seamicro_username
: SeaMicro Username with administrator privileges.seamicro_password
: Password for the above SeaMicro user.deploy_kernel
: The Glance UUID of the deployment kernel.deploy_ramdisk
: The Glance UUID of the deployment ramdisk.seamicro_api_version
: (optional) SeaMicro API Version defaults to "2".seamicro_terminal_port
: (optional) Node's UDP port for console access. Any unused port on the Ironic conductor node may be used.
The following sequence of commands can be used to enroll a SeaMicro node and boot an instance on it:
Create nova baremetal flavor corresponding to SeaMicro server's config:
nova flavor-create baremetal auto <memory_size_in_MB> <disk_size_in_GB> <number_of_cpus>
Create Node:
ironic node-create -d pxe_seamicro -i seamicro_api_endpoint=https://<seamicro_ip_address>/ -i seamicro_server_id=<seamicro_server_id> -i seamicro_username=<seamicro_username> -i seamicro_password=<seamicro_password> -i seamicro_api_version=<seamicro_api_version> -i seamicro_terminal_port=<seamicro_terminal_port> -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>
Associate port with the node created:
ironic port-create -n $NODE -a <MAC_address_of_SeaMicro_server's_NIC>
Associate properties with the flavor:
nova flavor-key baremetal set "cpu_arch"=<cpu_arch>
Boot the Instance:
nova boot --flavor baremetal --image test-image instance-1
