Hmm, with these two, connected to an esiop in an Ultra 10 it works:
sd0 at scsibus0 target 1 lun 0: <IBM, DCAS-34330W, S61A> disk fixed
sd0: 4134 MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sect x 8467200
sectors=20
sd0: sync (50.00ns offset 15), 16-bit (40.000MB/s) transfers, tagged
queueing=20
sd1 at scsibus0 target 2 lun 0: <SEAGATE, ST150176LW, 0002> disk fixed
sd1: 47702 MB, 12024 cyl, 22 head, 369 sec, 512 bytes/sect x 97693755
sectors=20
sd1: sync (50.00ns offset 15), 16-bit (40.000MB/s) transfers, tagged
queueing=20

... while these two, connected to a mesh in a UMAX S900 do not:
sd0 at scsibus1 target 0 lun 0: <SEAGATE, SX19171W, 9D23> disk fixed
sd0: 8683 MB, 5268 cyl, 20 head, 168 sec, 512 bytes/sect x 17783112
sectors
sd1 at scsibus1 target 2 lun 0: <SEAGATE, ST34520N, 1281> disk fixed
sd1: drive offline

For some reason I don't get any SCSI-related error messages at all on
the S900, all the SCSI options are the same, both kernels are built from
the same source tree, updated a few hours ago.

have fun
Michael
