How do you mount and use mapped raw lun in Linux?

I have a virtual RHEL 5 32 bit guest running on an ESX3.5 server. Disk 1 for the guest is a 10GB virtual disk where the RHEL OS is installed. I added Disk 2 to the VM which is a 500GB Mapped Raw LUN. How do I get RHEL to see and use the new disk? My Linux experience is very limited.

Thanks for any help.

1) identify the device thath the raw mapped drive is, i.e /dev/sdb or similar

2) create a mount point somewhere in your Linux VM, like /mnt/rawdrive, or /newmount, etc.

3) mount the the LUN using
mount /dev/sdb /mnt/rawdrive

4) if this is permanent add an entry in /etc/fstab
a good description of the options is lited in


make sure you know what the device is
and make sure you pick the mount point you want.

if its wrong you can always
unmount /mnt/rawdrive
if it mounted at all.
if nothing to unmount, then probably you picked the wrong device in /dev to mount in the fist place.

I have no idea how to use linux guests to do this ... but I found these link which I hope can help you ...

I ended up having to reboot the VM to see the new disk in /dev. Once I saw it in /dev it was pretty easy to mount. Thanks.
