Can anyone tell me why the error:
"Cannot open /dev/raw/raw1" occurs.
I am using a database called D3 on Linux Redhat Enterprise WS4 which is
supposed to write its data into an existing partition mounted as /opt and on
boot up that partition is bound to /dev/raw/raw1.
Is this a permissions problem?
I tried making d3 owned by root but the same error occurred.

This is a BIOS weirdie. In BIOS, the first bootable drive is given the
BIOS device value of 0x80. The second drive is 0x81 and so on. The
problem here is that you've set things up to boot from /dev/sdb (BIOS
drive 0x81) but the BIOS still wants to use device 0x80 (/dev/sda).

Take a look at the "--device-map" options in grub to see how to fix the
mapping.
