Installed latest Debian on RAID1, which is VD-00. Installation went through
without any issue.
After installation system can not boot. Checked BIOS and there are only 3
options to boot from: CD-ROM, NIC, Drive C(I'm not sure where drive C came
from???).
The "C" drive is from Dell (part of the OS/diagnostic stuff they
include). You should be able to delete that if you like as, IIRC, the
tools are available via a bootable CD that is included with the machine.
I believe the ISO is also available for download,
In the RAID configuration utility VD-00(2 HDD in RAID1)is set as boot device
but it's still can not see the boot sector.
Is it something wrong with the system or did I need to set some settings on
software level?
PERC card, yes?
Check that the megaraid_sas driver is loading. When I installed Etch, I
had to rebuild the initrd with that module after the initial install.
Also, do you have a DRAC in that box? If so, check the /dev/sd* list in
the fstab and menu.lst files. The DRAC has a 'virtual drive' that is
presented to the kernel as a USB device and in my case, was enumerated
before the RAID card, throwing off the drive list (/dev/sda* became
/dev/sdb* or some such thing).
