The device mapper is trying to tickle each block device.  /dev/hdc is 
your IDE CD-ROM drive, and the device mapper is checking it.  Since it 
is empty, you get the warning.  It's not an issue, you can safely ignore 
it.

If you are dead-set on not seeing that error, edit /etc/lvm/lvm.conf and 
filter /dev/hdc.  There is an example line in the conf file you can use. 
  Please read the comments, you will note that only one filter line is 
allowed.

You might play with something like:

# Exclude the cdrom drive
filter = [ "r|/dev/hdc|" ]
