In a number of RH Enterprise 1.4.0 systems
I created a swap logical partition with the logical
parameters :

eds7:/root] # fdisk -l

Disk /dev/sda: 146.1 GB, 146163105792 bytes
255 heads, 63 sectors/track, 17769 cylinders

  Block device           253:5
   from anaconda :

#logvol swap --fstype swap --name=LogVol01 --vgname=VolGroup00 --size=16000

We have a disaster recovery machine , which should be configured
similarily. 

The installer did not follow the prototype , and for swap
has :

# fdisk -l

#part swap --noformat --onpart sda5

Is it possible to convert the swap unformatted partition
on this machine, to the swap logical volume the other machines have.

The swap unformatted logical partition looks undersized ,
