Hi Airship, We had a discussion in OpenDesign meeting last thursday on bringing error states for disks and other devices so that we can label appropriate error in HOST CR. I had done good amount of investigation on Ironic Introspection data. After studying Ironic introsepction data, Ironic has taken care of these things already. Here is my understanding - - If one of the disk is error state, then Ironic introsepction fails in that case or it stuck in inpecting state for long time and fails after it. - We are pulling only BM hosts which are in READY state, so READY state comes after successful execution of Introspection state. - Here we can consider that current hardware inventory data is suffice. - HCC (Hardware-classifcation-controller) will perform classification and validation filter by comparing with HCC profile and label the BaremetalHost CR as BMO-OK. Thanks, Digambar
