Hello guys,

Very strange problem I have just encountered. If I stick (in Redneck
language...) a SMART-2 IDA raid controller in a Proliant/1600 which has
two on-board NCR adapters (aka Compaq SCSI) and try to install Red Hat 5.1
on a disk attached to one
of the NCRs that already has 3 partitions (one Compaq SYSTEM, one UnixWare
7 and another UnixWare 2) then the Linux fdisk does not see any partitions
on /dev/sda at all! I was afraid to create new partitions and rebooted
back to UnixWare until I think of a way to create Linux partitions without
disturbing the other ones...

Before you rush into replying with "Linux does not support SMART-2" let me
tell you that I know that very well - that is the whole point, if you know
what I mean ;) At the moment I just want Linux to see the /dev/sda on the
onboard NCR adapter, which it can see fine (with all the UnixWare
partitions) if I disconnect the SMART-2. How could the presence of a
SMART-2 controller suddenly shadow the partition table of the /dev/sda?

Still thinking...

Any ideas?

Thanks in advance,
