Queens Series Release Notes


Bug Fixes

  • Fix an issue where SCSI LUN scans for FC were unnecessarily too broad. Now OS-Brick will not use wildcards unless it doesn’t find any target ports in sysfs and the Cinder driver doesn’t disable them.


Bug Fixes

  • Always check if we are dealing with a single WWNN Fibre Channel target, even when we receive an initiator_target_map. This allows us to exclude unconnected HBAs from our scan for storage arrays that automatically connect all target ports (due to their architecture and design) even if the Cinder driver returns the initiator_target_map, provided the target has a single WWNN. Excluding these HBAs prevents undesired volumes from being connected.


Bug Fixes

  • Under certain conditions detaching a multipath device may result in failure when flushing one of the individual paths, but the disconnect should have succeeded, because there were other paths available to flush all the data.

    The multipath disconnect mechanism is now more robust and will only fail when disconnecting if multipath would lose data.


Bug Fixes

  • [bug 1722432] Changes the supported_transports to support tcp transport. With this change, we can define an custom iface with tcp transport to limit the storage traffic only be transimitted via storage NIC we specified.


Upgrade Notes

  • The location for connector constants was moved in the 1.6.0 release, but their old location was kept for backwards compatibility. These legacy constants are now being removed and any out of tree code should be updated to use the latest location (os_brick.initiator.CONSTANT_NAME).
