The SCSI core surfaces this condition to the caller rather than retrying it. For the RPMB well-known LU the first command after boot is the first RPMB frame, and RPMB has no earlier, guaranteed access that could clear the condition beforehand. The power-on UNIT ATTENTION therefore reaches RPMB and fails that first frame, breaking RPMB on every cold boot. The RPMB WLUN needs the power-on UNIT ATTENTION to be retried so that RPMB works from the very first access after a power cycle.
