Current Series Release Notes¶

11.2.0-15¶

Adds support for the is_root_volume property in software RAID configurations. The property can be set to True on a RAID volume to indicate that it should be used as the root device for OS installation. When set to False, the volume and the underlying physical devices and partitions are excluded from consideration as potential root devices. It defaults to None, which has no effect on root device selection.

Adds support for automatically skipping BMC detection via ipmitool when Ironic indicates the node uses out-of-band management interfaces (e.g., Redfish, iDRAC Redfish, iLO, iRMC). This reduces deployment time and avoids unnecessary ipmitool calls when the BMC information is already known to Ironic.

BMC information (address, v6address, and MAC) is now cached after the first detection to avoid repeated expensive ipmitool calls during subsequent inventory collections. This improves performance during heartbeats and long-running operations like cleaning or rescue mode.

Support for Python 3.9 has been removed. Now Python 3.10 is the minimum version supported.

If a volume_name is present in the skip_block_devices property, the function validate_confiuguration will now fail unless all logical disks in the target_raid_config have a volume_name specified.

Fix a conditional which is supposed to check whether there are any erasable devices. In the previous state, the conditional was wrong as the call was missing the node as a parameter.

Fixes matching hints with lists of WWN/Serial which was only handled in some cases - due to the issue, it was possible to choose a device listed in the skip_block_devices property as a root device.

Fixes an issue where the agent could not find a valid IP address when the Ironic API was running on a non-standard port. The reachability test now uses the full API URL including the port number, instead of only using the hostname. This prevents LookupAgentIPError when connecting to Ironic APIs on custom ports.

Fixes RuntimeError when entering rescue mode by checking if the heartbeater thread is alive before attempting to stop it.

The skip_block_devices property now supports RAIDs, including scenarios with multiple arrays on the same physical disk. This included 6 smaller bugs that have all been addressed.

The agent now tests Ironic API URL reachability via HTTP during startup before determining the advertised IP address. Unreachable API URLs are filtered out, preventing the agent from advertising an IP address that cannot actually reach the Ironic API. This improves reliability when multiple API URLs are configured or in complex network topologies. The IP reachability test uses the configured http_request_timeout (default 30 seconds) timeout for the HTTP request.
