SCSI: old vs. new disks?

[Tony Movshon]

I recently attached an old SCSI shoebox (rescued from a 3/50) to a new
SS1+ running SunOS 4.1. The shoebox contains a home-installed Maxtor 2190
(on an Adaptec controller) and an Exabyte 8mm tape drive. Without change
of jumper settings, the SS1+ finds the Maxtor disk at sd3, but when it
boots it reports the following:

	sd3: non-CCS device found at target 0 lun 0 on esp0
	sd3 at esp0 target 0 lun 0
	sd3: <Maxtor XT-2190 cyl 1222 alt 2 hd 15 sec 17>

It finds the Exabyte without trouble, and thereafter, everything seems to
work fine. Two questions:

	1. What does "non-CCS device" mean?
	2. Should I worry about it?
