RAID 1 in RH9
 

After setup RH9 with software RAID 1, there are:

/dev/md0 /boot
/dev/md1 /

where
/dev/md0 = /dev/hda1 and /dev/hdc1
/dev/md1 = /dev/hda5 and /dev/hdc5
(others are all swap)

When I shutdown the server and plug-out hdc cable, the system can start as predicted.
However, while plug-out hda, it cannot bootup with hdc only, but it is supposed to can.

In RAID1, the two harddisk should be identical, but why can't /dev/hdc works as /dev/hda ?
Is there anything wrong?

Does the BIOS know to boot the third IDE device?

A lot of newer BIOS' will allow IDE1 IDE2 IDE3 IDE etc as bootable devices.

Yes, it does.
