What kind of interface are the discs connected to? Is it some kind of hardware raid card?

Subject: Re: [OCLUG-Tech] Problem with the changing order of drives
Strange that the udev rules aren't working ...
One approach is to debug that. Make sure no statements are causing
the udev rules you show below to be skipped, and/or move them earlier in
the sequence of udev rules (to help with finding what's causing them
to be skipped - if that is what's happening).
Another approach is to use volume names. I don't know offhand how
to do that or I'd give some pointers right here. My guess is
you give volume names to the disks (they get written on the disks),
then use the volume names to mount the drives rather than the
device names.
