 	Well, that's an LVM volume. You have to run first pvscan (or lvm 
pvscan) and see what physical volumes are created (let's hope you'll find 
/dev/hdc2 there) and what volume groups are available on that physical 
volume. After that you have to run lvscan (or lvm lvscan) and see what 
logical volumes are available (assuming that the current running kernel 
supports the LVM version of that volume).

 	Running pvscan rull generate the and output alike with the 
following:

pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/hdc2" of VG "Volume00" [33.59 GB / 0 free]
pvscan -- total: 1 [33.60 GB] / in use: 1 [33.60 GB] / in no VG: 0 [0]

 	So let's say the volume group you're looking for is the one from 
/dev/hdc2 and is named "Volume00". After that you'll have to run lvscan 
and see what logical volumes are created there:
 	The output of the "lvscan" command will be something like:
lvscan -- ACTIVE            "/dev/Volume00/LogVol00" [1 GB]
lvscan -- ACTIVE            "/dev/Volume00/LogVol05" [4 GB]
lvscan -- ACTIVE            "/dev/Volume00/LogVol04" [512 MB]
lvscan -- ACTIVE            "/dev/Volume00/LogVol06" [11.72 GB]

 	...and so on. Keep looking for the ones with "Volume00" (or the 
name of the volume created on your partition, /dev/hdc2).

 	After finding that lovical volume all you'll have to do is:

mount /dev/Volume00/whateverthelogicalvolumeiscalled /mount/point/ -t ext3

 	Let's hope you don't have any other LVM volume groups with the 
same name on your computer...
