19#  Ensure that the GPFS system files on the specified nodes are at the most
20#  recent level.  If the -f (force) option is specified, rebuild the files
21#  even if they appear to be at the latest level.
22#
23#  Usage:
24#
25#    mmrefresh [-f] [-a | -N {Node[,Node...] | NodeFile | NodeClass}]
26#
27#  where:
28#
29#    -f            Rebuild the GPFS system files even if they appear
30#                  to be at the most current level.
31#
32#    -a            Check all nodes in the GPFS cluster.
33#
34#    -N Node,Node,...  Specify the nodes whose state is desired.
35#    -N NodeFile       NodeClass may be one of several possible node classes
36#    -N NodeClass      (e.g., quorumnodes, managernodes, nsdnodes, etc.)
37#
38#
39#  If not explicitly specified otherwise, only the local node is checked.
40#
41#
42#  Obsolete options:
43#
44#   -C NodesetId  Check all nodes in the specified nodeset.
45#                 Assumed to be the same as -a.
46#
47#   -W NodeFile   Check all nodes whose reliable hostnames
48#                 are listed one per line in NodeFilename.
49#                 Cannot be specified with -a, -N, -w, or -n.
50#
51#   -w nodenames  Check all nodes whose reliable hostnames
52#                 are in the comma-separated nodenames list.
53#                 Cannot be specified with -a, -N or -W.
54#                 If both -w and -n are specified, the lists are combined.
55#
56#   -n nodenums   Check all nodes whose node numbers are
57#                 in the comma-separated nodenums list.
58#                 Cannot be specified with -a, -N, or -W.
59#                 If both -w and -n are specified, the lists are combined.
