Except in some specific cases of retries after a unit attention condition, retries are usually indicative of hardware trouble. Don't most devices already use a number of internal retries which is appropriate when they are healthy ? When external retries become necessary and frequent, the situation is bad, and subsequent failures are quite probable. Better to be warned earlier. (There are also the retries caused by scsi protocol problems - bad bus - but these are usually followed by a bus reset which is logged ?) And, by the way, 'recovered errors' sense keys (problems solved internally by the device) should also be logged for the same reason, only more benign, (but I'm not too sure that many devices actually generate these).
