I started an old Virtual Machine in the UAT environment. The output for uname -a is :

Linux pawana 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

There 3 disks attached to it.

1) /dev/sda => contains the OS partitions and LV's

2) /dev/sdb1 => is an ext2 file system

3) /dev/sdc[1-3] => could not mount these device using the mount command.

so I used the command file -sL /dev/sdc[1-3] to identify the file system type for the device. Below is the output :

[root@pawana ~]# file -sL /dev/sdc[1-3]

/dev/sdc1: data

/dev/sdc2: data

/dev/sdc3: data

What type of file system is this ?? If at all it contains any data how can access that ?

    Are any of the /dev/sdc[123] partitions mentioned in /etc/fstab? Or anywhere in /etc (grep -irl 'sdc[123]' /etc)? Does the VM have any apps installed that make use of raw, unformatted partitions? (e.g. the oracle database software can optionally use raw partitions). BTW, if file -s can't identify the partition type(s), it's probably not a formatted filesystem. Maybe try hexdumping it, e.g. hd /dev/sdc1 | less and see if there's anything you recognise. – cas Jun 07 '16 at 04:44

Try running 

fsck -N /dev/sdc1

If that doesn't work you can try with the mount auto option to see if it gets mounted but looking at your file output it could be just no filesystem on it.
