19#  List information for the disks that belong to a GPFS cluster.
20#
21#  Usage:
22#
23#     mmlsnsd [ -a | -F | -f Device | -d "DiskName[;DiskName]" ]
24#             [ -L | -m | -M | -X ] [-v]
25#
26#  where
27#
28#     -a          list all disks.  This is the default.
29#
30#     -F          list all disks that do not belong to any file system.
31#
32#     -f Device   list all disks that belong to file system Device.
33#
34#     -d "DiskName[;DiskName]"  list the disks in the specified list
35#                 of ";"-separated disk names.
36#
37#     -L          display longer disk information.
38#
39#     -m          display the disk device name on the local node,
40#                 or, if applicable, the disk device names on the
41#                 primary and backup server nodes.
42#
43#     -M          display the disk device names on all nodes to which
44#                 the disk is attached.  Caution:  This is a slow operation!
45#
46#     -v          display additional error information where available.
47#
48#     -X          display eXtended disk information.
