It's a SCSI drive; in's a Dell 220F enclosure connected via a QLA2200 adapter. I've pulled the bad disk (tho not 'yellow' at the hardware level; and re-inserted it -- but to no avail. It did cause a reset; but the device remains 'disabled'. Aug 31 11:48:05 abyss kernel: qla2200 0000:00:09.0: LIP reset occured (f701).
