DEFBUG(CHK,CC1IS6,PHYC1,HARD,<PHYC1 - Disk drive is in logging mode>,<<UDBAKA(P3),UNIT>,<SSASCI(P1),SUBCHN>>,<
Cause: Sense bytes 0-3 indicate environmental data, but sense byte

Cause: A device interrupted which had a device address not in the
range of one of the known devices.
Action: If a new device has been added to the channel with this address,
