xCAT Driver for ironic x86/64 machine
|
||
|
|
==================================
|
||
|
|
|
||
|
|
xCAT is a Extreme Cluster/Cloud Administration Toolkit. We can use xcat
|
||
|
|
to do :
|
||
|
|
1 hardward discoveery
|
||
|
|
2 remote hardware control
|
||
|
|
3 remote sonsole
|
||
|
|
4 hardware inventory
|
||
|
|
5 firmware flashing
|
||
|
|
|
||
|
|
Ironic is a project in Openstack, it will replace the nova-baremetal in juno release. Ironic's design is very flexable, we can add driver to extend function
|
||
|
|
without change any code in Openstack. Ironic xCAT driver takes the advantage of xcat and openstack, we can use it to deploy the baremetal machine very easily.
|
||
|
|
|
||
|
|
Before using this driver, we must setup the openstack environment at least for two nodes( ironic conductor and neutron network node can't setup on the same node)
|
||
|
|
Ironic conductor and the baremetal node( waiting for deploy) must in the same vlan
|
||
|
|
|
||
|
|
Add the follows in the ironic egg-info entry_points.txt file (ironic.drivers section)
|
||
|
|
|
||
|
|
pxe_xcat = ironic.drivers.xcat:XCATBaremetalDriver
|
||
|
|
|
||
|
|
When the openstack with ironic is ready, just execute command in the ironic_xcat directory as follows:
|
||
|
|
|
||
|
|
$ python setup.py install
|
||
|
|
|
||
|
|
Restart the ironic-conductor process
|
||
|
|
|
||
|
|
Initialize the xcat environment according to http://sourceforge.net/p/xcat/wiki/XCAT_iDataPlex_Cluster_Quick_Start/
|
||
|
|
Using xCAT baremetal driver need config site table and run copycds to generate image. The node definition is not requirement.
|
||
|
|
|
||
|
|
Ironic use neutron as the network service.
|
||
|
|
Check the openvswitch config on the network node ,make sure brbm bridge connect to the baremetal node.
|
||
|
|
|
||
|

|
||
|
|
Some Example to use the xCAT baremetal driver.
|
||
|
|
|
||
|
|
$touch /tmp/rhelhpc6.5-x86_64-install-compute.qcow2;glance image-create --name rhelhpc6.5-x86_64-install-compute --public --disk-format qcow2 --container-format bare --property xcat_image_name='rhels6.4-x86_64-install-compute' < /tmp/rhelhpc6.5-x86_64-install-compute.qcow2
|
||
|
|
--name rhelhpc6.5-x86_64-install-compute is the image name in xcat. You can use lsdef -t osimage on the ironic-conductor node which xcat is installed.

|
|
|
||
|
|
$ ironic node-create --driver pxe_xcat -i ipmi_address=xxx.xxx.xxx.xxx -i ipmi_username=userid -i ipmi_password=password -i xcat_node=x3550m4n02 -i xcatmaster=10.1.0.241 -i netboot=xnba -i ipmi_terminal_port=0 -p memory_mb=2048 -p cpus=8
|
||
|
|
|
||
|
|
$ ironic port-create --address ff:ff:ff:ff:ff:ff --node_uuid <ironic node uuid>
|
||
|
|
|
||
|
|
$ nova boot --flavor baremetal --image <image-id> testing --nic net-id=<internal network id>
