I was amazed at the speed with which the responses came in. It seems I
may have been a bit hasty jumping all over Sun. What I was able to
glean from the responses I received was:
1) There is a problem with mixing SMD and IPI controllers in 4/[34]90s.
Sun is aware of the problem and working to fix it. Rumors are that it
will require a hardware fix to the CPU and possibly the backplane
(ouch!). Another rumor is that it can be corrected with software.
Anyone from Sun care to comment on this?
2) You can indeed connect SCSI disks to a 4/[34]90 under 4.1.1, but Sun
does not support this. Sun is using 'support' in the literal sense,
meaning it may work but don't ask Sun to fix any problems you may
encounter while using it.
Also, it would appear that Sun will tell you that if you do install
a SCSI disk, you can not use it as a boot device. One person who
responded told me that is exactly what he is doing. SunOS is
installed on the SCSI disk and his data all reside on the IPI
drives.
3) My salesrep said he would "Check into the question of trading in the
SMD disks for IPIs". I am not holding my breath.
So, while it probably could have been worded better in the release
notes it seems that the world is not coming to an end as we know it.
:-)
One other thing. We have only received the release notes, no tapes
yet. I am assuming that the tapes will be arriving within a week or
so. Our regional SE got his on Monday of this week. There would also
appear to no longer be any PSR or 4c specific releases (hurray!). Does
anyone know if this is true?
