RHEL6 seems to prefer to use UUIDs in /etc/fstab instead of device names. So, will want to do something like this to get the uuid.

[root@server]# blkid|grep sda1 >> /etc/fstab

This then gets added to /etc/fstab.
/dev/sda1: UUID=”a7a23967-f2c5-43a7-9245-270a818b6106″ SEC_TYPE=”ext2″ TYPE=”ext3″

Edit the line so it looks like this:
UUID=a7a23967-f2c5-43a7-9245-270a818b6106 /local/s13 ext3 defaults 1 2
