"Formating" a partition is done by simply creating a filesystem on that device. For example:

mkfs.ext4 /dev/mapper/VG00-LogVol

But be sure you know what you are doing. You can really destroy data that way.

Its redhat 5 so isn't it should be mkfs.ext3 /dev/mapper/VG00-LogVol instead mkfs.ext4. Yes We already have taken the backup – Umair Mustafa Jan 12 at 13:24

You have to decide yourself what kind of filesystem is best for your case. ext3 is probably fine. – michas Jan 12 at 13:37
I tried to run the command mkfs.ext3 /dev/mapper/VG00-LogVol but its saying that /dev/mapper/VG00-LogVol is apparently is in use by the system, will not make a filesystem. Although i have unmounted the filesystem – Umair Mustafa Jan 12 at 13:40

Red Hat distros should have a GUI tool for this called "Disks" installed, and yes, be extremely careful, especially if you're running on a manufacturer-built machine because often times people end up voiding their warranty messing with partitions because the manufacturers almost always have a partition full of recovery tools hidden somewhere.
