Add swap disk and remove swap disk

By using below commands, collect required disk information and mount points

 # df -hT 
 # fdisk -l
 # lvdisplay
 # pvdisplay
 # lvs
 
 # lsblk -o NAME,KNAME,MAJ:MIN,FSTYPE,MOUNTPOINT

 # lsblk -o NAME,KNAME,MAJ:MIN,FSTYPE,MOUNTPOINT | egrep 'dm-0|dm-1'

 # free -g

 # swapon /dev/sde

 # free -g

 # swapoff /dev/sdd
