19#  The GPFS daemons on the specified nodes will be started.
20#
21#  Usage:
22#
23#    mmstartup [-a | -N {Node[,Node...] | NodeFile | NodeClass}]
24#              [-E EnvVar=Value...] [ -T ]
25#
26#  where:
27#
28#    -a            Start the daemon on all nodes in the GPFS cluster.
29#
30#    -N Node,Node,...  Specify the nodes on which the daemon is to be started.
31#    -N NodeFile       NodeClass may be one of several possible node classes
32#    -N NodeClass      (e.g., quorumnodes, managernodes, nsdnodes, etc.)
33#
34#    -E EnvVar=Value  Specify an environment variable to be passed to the GPFS
35#                     daemon.  More than one -E option can be specified.
36#
37#    -T            start tracing at daemon startup and cut a trace report
38#                  at daemon shutdown
39#
40#
41#  If not explicitly specified otherwise, the daemon is started on the local
42#  node only.
43#
44#
45#  Undocumented options:
46#
47#    -e seconds    Estimated startup time (in seconds).  During this time
48#                  period, the mmsdrfs file is guaranteed not to change.
49#                  Specifying a value of 0 disables the locking that would
50#                  otherwise take place for large non-sp clusters.
51#
52#    -f            Force the loading of the kernel extensions (Linux only).
53#
54#    -G            Force trace records to be cut on all nodes when there is
55#                  a daemon failure on some node.
56#
57#    -t {yes|traceFile}  Start the mm commands tracing facility.  If traceFile
58#                   is specified, it must be a fully qualified pathname.
59#                   Otherwise, the trace results are appended to file
60#                   /tmp/mmfs/mmScriptTrace.
61#
62#
63#  Obsolete options:
64#
65#    -C NodesetId  Start the daemon on all nodes in the specified nodeset.
66#                  Assumed to be the same as -a.
67#
68#    -W NodeFile   Start the daemon on all nodes whose reliable hostnames
69#                  are listed one per line in NodeFilename.
70#                  Cannot be specified with -a, -N, -w, or -n.
71#
72#    -w nodenames  Start the daemon on all nodes whose reliable hostnames
73#                  are in the comma-separated nodenames list.
74#                  Cannot be specified with -a, -N or -W.
75#                  If both -w and -n are specified, the lists are combined.
76#
77#    -n nodenums   Start the daemon on all nodes whose node numbers are
78#                  in the comma-separated nodenums list.
79#                  Cannot be specified with -a, -N, or -W.
80#                  If both -w and -n are specified, the lists are combined.
