A month later, no more errors:
The source of the messages turned out to be an incompatible IBM
2Gb drive (PN 75G3576) on the end of a chain of 3 4Gb Seagate drives.
Once I removed the drive, the errors stopped occuring.
Since the errors didn't directly point to a drive incompatibility, but more
towards a SCSI card problem, I first tried replacing the card with no
effect. Then I tried turning off tagged command queue as suggested by one
sun manager, and when that didn't work, I finally tried removing the drive.
Thanks to all those who responded:

Bern's reply might help others with a similar problem:
Take a look at your /etc/system script and if it's not in there
you might add the following.
set scsi_options = 0x378
This will turn off tagged command queue support which is a "feature"
not handled at all well by most disks and the isp. Problems
seem to most often arise during high/sustained disk activity, and/or
whenever you *really* want to get some work done :)
Original post:
I get these errors once or twice a day on a Sparc 20
running Solaris 2.5, with a Fast/wide differential SCSI
card installed:
