If this is true - and I think so, I wasted a lot of time on it
already - so why isn't there a little piece of documentation
speaking out a warning. We've been happily using a large number of
GDT controllers under FreeBSD for years after we have had a couple
of bad experiences with other brands.
One of those, a mylex 160lp was just tested to be unfunctional with
6.1b2 (8GB RAM), too.
Are there any *good* SCSI RAID controllers out there that are known
to be working in server setups (amd64, SMP, >4GB RAM)?
When thinking it over, I guess I have to be grateful that over many
years I never experienced s/th that made me question the "The Power
To Serve" slogan. What I really feel unhappy about right now is that
there was no information available so I could take appropriate
measures in order to avoid the current situation (at least none that
I could find).
Well, what's the plan regarding the iir driver now? I would suspect
that letting folks rendering their servers unfunctional by upgrading
memory is not really a good strategy.
The manpage lists two authors/maintainers, I emailed both early this
week. Achim Leubner will be back from vacation the 27th. So maybe he
can contribute s/th constructive.
Kind regards,
