Dear SM's,
thanks for all the replies you sent on my
question:

>Is there any known incompatibility with Solaris
>2.5.1 drivers and SCSI-specs? Tagged command
>queueing and so?
>I want to run this drive in a SPARC-4-85MHz

Most answers did point out that SUN itself
ships some entry-level systems with Quantum
Fireball SCSI-harddisks installed and so there
should be no problem at all.
Others told me of their Quantum harddrives which
all run perfect in different SPARCs under Solaris
2.x.
But!!! I buyed two of the mentioned drives and
plugged them into two SPARC-5 systems running
Solaris 2.5.1. Boom! The SCSI-errors were manifold...
It turned out that this drive does _not_ support
the tagged-command-queuing feature of SCSI-2.
The only one whos answer was right (but came too late):
