Removes multipath base devices from consideration by default, and instead allows the device-mapper device managed by multipath to be picked up and utilized instead. In effect, allowing us to ignore standby paths *and* leverage multiple concurrent IO paths if so offered via ALUA. In reality, anyone who has previously built IPA with multipath tooling might not have encountered issues previously because they used Active/Active SAN storage environments. They would have worked because the IO lock would have been exchanged between controllers and paths. However, Active/Passive environments will block passive paths from access, ultimately preventing new locks from being established without proper negotiation. Ultimately requiring multipathing *and* the agent to be smart enough to know to disqualify underlying paths to backend storage volumes. An additional benefit of this is active/active MPIO devices will, as long as ``multipath`` is present inside the ramdisk, no longer possibly result in duplicate IO wipes occuring accross numerous devices.

Ironic Python Agent
Team and repository tags
Overview
An agent for controlling and deploying Ironic controlled baremetal nodes.
The ironic-python-agent works with the agent driver in Ironic to provision the node. Starting with ironic-python-agent running on a ramdisk on the unprovisioned node, Ironic makes API calls to ironic-python-agent to provision the machine. This allows for greater control and flexibility of the entire deployment process.
The ironic-python-agent may also be used with the original Ironic pxe drivers as of the Kilo OpenStack release.
Building the IPA deployment ramdisk
For more information see the Image Builder section of the Ironic Python Agent developer guide.
Using IPA with devstack
This is covered in the Deploying Ironic with DevStack section of the Ironic dev-quickstart guide.
