UUID stands for Universally Unique Identifier. I use UUID for my disk device, when I need to create and add disks for Oracle ASM, as UUID is independet of device name or mountpoint. So its always a good idea to include UUID of device in the fstab file in Linux.

So here is how to find the UUID of a device in Linux for Oracle ASM:




[root@bastion ~]$ ls -l /dev/disk/by-uuid
lrwxrwxrwx 1 root root 11 JAN 18 20:38 1101c254-0b92-42ca-b34a-6d283bd2d31b -> ../../sda2
lrwxrwxrwx 1 root root 11 JAN 18 20:38 11dc5104-C07b-4439-bdab-00a76fcb88df -> ../../sda1

HTH.
