19#  Usage:
20#    mmcrnsd -F DescFile [-v {yes | no}]
21#
22#  where
23#    -F DescFile    specifies a file containing the disk descriptors for
24#                     the network shared disks to be created
25#    -v {yes | no}  verification flag; a value of "yes" specifies that the
26#                     disks in DescFile should only be created if they have
27#                     not been previously formatted as an NSD, while a value
28#                     of "no" specifies the disks should be created regardless
29#                     of whether they have been previously formatted or not.
30#                     The default value is "yes".
