CDC Wren V on SUN SPARC station

[Hubert Broze]

We have a problem with the following configuration: a SUN SPARC station
(4/60) with 2 internal disks of SUN (Quantum Prodive 105S), a floppy, 2
Ethernet controlers and 2 external disk drives CDC Wren 94181-702 (coming
from another supplier), supporting SCSI II (synchroneous SCSI bus).  We
received the following error message:

Mar  8 16:30:01 info-sparc1 vmunix: esp0:       unwanted data out
Mar  8 16:30:01 info-sparc1 vmunix: sd2:        SCSI transport failed:

The disk is perfect, and it runs on a SUN 3/60 (asynchronous SCSI).  Our
local dealer of SUN says that SUN does not support this model of the disk;
I found it in the /etc/format.dat in SUN OS 4.0.3.c ???  Any idea to solve
this problem ?

Please, answer by mail because I dont read the news for the moment: I
receives them on that disk ....
