Hi,
I am attempting to use the Dell OEM version of the AMI Megaraid 428 SCSI
RAID controller. I'm using RedHat Linux 5.2 for Intel along with the 0.92
version of the megaraid driver which is distributed with RedHat's 2.0.36
kernel. So far, I have been unable to get the kernel to recognize the
configured logical drives as SCSI targets. I've tried using the driver as
a module and as part of a monolithic kernel. The computer is a Dell Xeon
Precision Workstation with onboard Adaptec SCSI controllers.
I have configured the controller with two disks - one attached to each of
the internal SCSI connectors. I have used the AMI bios setup menus to
configure and initialize these two disks as a single, RAID-0 logical
drive.
What seems especially strange is that the driver reports that it finds a
logical drive, but then reports zero SCSI targets.
In September I used the megaraid patch against the 2.0.32 kernel with a
very simmilar setup, and it worked fine.
Can anyone help?
Thanks,
Chance
