#   COMPONENT_NAME: CSPOC Command Line Interface
#
# Name:
#   cl_ls_free_lvs
#
# Description:
#   Given the type of logical volume (jfs or jfs2), find all logical volumes
#   in the cluster of that type which do not have file systems defined on them.
#
# Arguments:
#   Logical volume type, 'jfs' or 'jfs2'
#
# Return Values:
#   Available log logical volumes of the given type (jfs or jfs2)
#   written to stdout along with the owning volume group, resource group and
#   node list.
