Local internal hard disk gets renamed once SAN is attached.
The server initially was installed with the internal disk attached only, the local disk was named /dev/sda, once the SAN disks get attached, new devices are detected and the local disk gets renamed to a different device name.
The server is still able to boot from the internal local disk, even though the disk received a new name, because the configuration on /etc/fstab is setup to use the disk UUID.
Using the blkid we can obtain the disk UUID.
