What documentation should I check? That's actually an ATAPI error, not a SCSI error. If you want to know whether or not it is a problem, I would suggest contacting Soren Schmidt <sos@FreeBSD.org>, who is the author of the ATA subsystem. FWIW, in the SCSI world, a unit attention is the expected error condition after a bus or bus device reset. (In most cases, SCSI adapters reset the bus when the system boots.) Once you've gotten the error condition, the state is cleared and the next command will proceed without a unit attention error.
