Checked out the software/actors, confirmed they are alive, communicating. Took test exposure on apogee and guider, confirmed working fine. B1 ion pump failed to latch, vacuum pump was left on it. So we didn't focus and set CCD position on cameras. Took couple of biased on BOSS cameras. SP1 failed to read out without any error message. SP2 biases (bot r2 and b2) looks fine. "Boss exposure recover" readout data from netburners fine on SP1. It means that whatever failed should be before the netburner.
