Mount new file system by label from command line fails. Help

Need some command line help. Simple request really. I want to perform the operation of adding new disk into SLES 11 SP1. Thereafter partitioning the whole disk and giving it a label and use this as the mount option in /etc/fstab. And do it all from the command line.
These are my steps and what results with

mount: special device LABEL=sapdatan does not exist

1. Add disk hardware to the server OS and display the hardware

	 # dmesg | tail -100 | grep Attached
	 # fdisk -l

2. Create a partition using the whole disk as partition 1

	 # fdisk /dev/sdx
	 n
	 p
	 1
	 [ENTER] [ENTER]
	 w

3. Make a filesystem and label it at the same time and do not reserve any blocks for superuser (-m)

	 # mkfs -t ext3 -L sapdatan /dev/sdx1 -m 0

4. Create a directory to mount the filesystem on

	 # mkdir /oracle/SID/sapdatan

5. Edit /etc/fstab and put the entry

	 LABEL=sapdatan   /oracle/SID/sapdatan    ext3  acl,user_xattr    1 2

6. Mount the filesystem

	 # mount -t ext3 LABEL=sapdatan /oracle/SID/sapdatan

root> mount /oracle/SID/sapdatan
mount: special device LABEL=sapdatan does not exist

At this point I have checked /dev/disk/by-label/ and there exists no symlink entry for sapdatan, of which I would expect for this to work. So what is populating this device tree structure and how to do at the CLI.

root> blkid
The output of this command shows that the device has LABEL=sapdatan

root> tune2fs -l /dev/sdx1
This shows that the filesystem volume name field : sapdatan

root> findfs LABEL=sapdatan
This command returns that its unable to find also.

How can I complete this at the command line so I can mount the filesystem by label.

I have to resort to using the partitioner GUI to get this final piece done. Pain.

Is it to do with running “udevadm trigger” command and if so what options should I use?

Hi
Mount via the device name, when/if you reboot the system it will come
up as the label.

Run the mount command it will show the device label.
eg;

mount /dev/sdc1  /oracle/SID/sapdatan
mount -l
/dev/sdc1 on /oracle/SID/sapdatan type ext3 (rw,acl,user_xattr) [sapdatan]
