Add the new disk to Volume group

For e.g.: if the disk is HP with Smart array

# pvcreate /dev/cciss/c0d1
# vgextend <volume_group_name> /dev/cciss/c0d1

Extend the Logical volume:
# lvextend -L<+mention_the_size> /dev/<volume_group>/<logical_volume>
eg: # lvextend -L+25G /dev/localhost/var
       # lvextend -L+10G /dev/localhost/home

Resize the file system:
# resizefs <file_system>
eg:
# resizefs /dev/mapper/localhost-var
# resizefs /dev/mapper/localhost-home
