My device files change!!!!

Hi...

this is the situation.

I have a server with redhat Advance Server 3 and the operating system is installed in /dev/sda disk... when i include new Luns dinamically they take the following special files /dev/sdb and /dev/sdc.... ok.. until now is everything ok... but the problem begins when i reboot the system.

I don't know why the system change the order of the device files and now the Operating System change to /dev/sdc and before it was in /dev/sda !!!! and the new Luns take /dev/sda and /dev/sdb instead of /dev/sdb and /dev/sdc...

this is a problem because every time that i would like to include a new Lun they gonna change the device files when i reboot the system!!!!!

How can i avoid this happened????

how can i tell to Linux that maintain the original device files and DON'T CHANGE IT ???????

Thanks for all the suggestions that you can give me.

Use labels in stead of devices on /etc/fstab.

Yes .. my /etc/fstab has the following entries:

/dev/Volume00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/Volume00/LogVol01 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

but this is the situation.... is any way to avoid that change the device file??? because is gonna be very dificult to do a management of disks if they change all the time that i reboot...

greetings....
