We had the same problem with the adaptec 39320 in a Dell Server. The proper driver for the adaptec U320 scsi should be aic79xx and it really is. The aic79xx driver of the Kernel 2.4.28 didn't recognise our scsi adapter. So we downloaded one from adaptec which was labeled as *minimally tested*, but this one works: http://download.adaptec.com/scsi/linux/aic7Yxx-2.0.12-6.3.9-linux-2.4.tar.bz2 or for kernel 2.6 series http://download.adaptec.com/scsi/linux/aic7Yxx-2.0.12-6.3.9-linux-2.6.tar.bz2
Did these updated modules work with HostRAID enabled? I haven't been sucessful in compiling them yet, which version of SuSE do you have?
This tarballs contain the source for following drivers: aic79xx (version 2.0.12) aic7xxx (version 6.3.9) They are more recent than the original ones in the kernel.
If you don't like kernel-compiling there's a chance to find a precompiled one on sites like http://www.adaptec.com/worldwide/support/drivers_by_product.jsp?sess=no&language=English+US&prodkey=ASC-39320D-R&cat=%2fProduct%2fASC-39320D-R
Strangely all the pre-compiled modules are for SuSE 8.0 and 8.2. There is one for 9.0, but it still has a 2.4 kernel. SuSE have released an update for SLES9, but of course its a different kernel variant and doesen't work with SL9.2 :-(.
Has anyone come across a solution? Is there a driver I don't know of? Is there a way of disabling hostRAID?
Did you find an answer to this? I have searched and searched the BIOS, the technical docs, and the web and have no solutions.
