The Redhat linux reboot puts me into a maintenance shell because disks are discovered and name differently.

Hi, We are put into a maintenance shell after a red-hat linux restart. The error message on the console is: ***** excerpt of error message **** /dev/mapper/rootvg-opt.vol ismounted. e2fsck: Cannot continue, aborting. /dev/mapper/rootvg-tmp.vol is mounted. e2fsck: Cannot continue, aborting. /dev/mapper/rootvg-usr.vol is mounted. e2fsck: Cannot continue, aborting. /dev/mapper/rootvg-var.vol is mounted. e2fsck: Cannot continue, aborting. *** An error occurred during the file system check. *** Dropping you to a shell; the system will reboot *** when you leave the shell. Give root password for maintenance (or type Control-D to continue): ***** End **** Details: We install redhat linux on raid5 device created on the local internal SAS disk. This disk is normally detected as /dev/sda. There is a 500M /boot partition called /dev/sda1. The remaining space is used to define the OS/rootvg volume group on which the OS logical volumes / file-systems like /, /var, /usr, /opt & /tmp are present. We also have EMC SAN storage zoned. These LUNs are used to build the user / application volume groups and file-systems. The problem; I guess is that the system is discovering & naming the disks in different order everytime the server is rebooted. For example the /dev/sda which represents the raid5 device created on local internal SAS disk is discovered as /dev/sdew ... and I guess this is the reason I am being dropped into the maintenance shell. I tell this because after I login to the maintenance shell I see that the /dev/sda represents a 500G SAN disk instead of a 600G internal disk. The internal disk is named /dev/sdew and if I disconnect the fibre cables; the server boots just fine. Is there a way to make sure that the disks are named consistently across reboots? Please suggest or point me in the right direction.
