19# Usage:
20#   mmcrcluster -N {NodeDesc[,NodeDesc...] | NodeFile}
21#               -p PrimaryServer [-s SecondaryServer]
22#               [-r remoteShellCommand] [-R remoteFileCopyCommand]
23#               [-C ClusterName] [-U DomainName] [-A] [-c ConfigFile]
24#
25# where:
26#
27#   -N NodeDesc,NodeDesc,...  specifies a comma-separated list of node
28#                             descriptors that detail the node interfaces
29#                             to be added to the cluster.  The nodes must not
30#                             presently belong to the cluster.
31#
32#   -N NodeFile         specifies a file of node descriptors that detail
33#                       the node interfaces to be added to the cluster.
34#                       The nodes must not presently belong to the cluster.
35#
36#   -p PrimaryServer    specifies the node to be used as the primary server
37#                       of the GPFS sdrfs data for this cluster
38#
39#   -s SecondaryServer  specifies the node to be used as the secondary server
40#                       of the GPFS sdrfs data for this cluster (optional)
41#
42#   -r remoteShellCommand    specifies the fully-qualified pathname for
43#                       the remote shell program to be used by GPFS.
44#                       The default is /usr/bin/rsh.
45#
46#   -R remoteFileCopyCommand  specifies the fully-qualified pathname for
47#                       the remote file copy program to be used by GPFS.
48#                       The default is /usr/bin/rcp.
49#
50#   -C ClusterName      user-specified name for the cluster.  If the name
51#                       contains dots it is assumed to be a fully-qualified
52#                       domain name.  Otherwise, the domain will default
53#                       to the domain of the primary configuration server.
54#                       If not specified, or if single dot is specified,
55#                       ClusterName will default to the fully-qualified name
56#                       of the primary config server (-p parameter).
57#
58#   -U DomainName       UID domain name
59#
60#   -A                  specifies automatic bringing up of mmfs daemons at
61#                       boot time.  Default is no autoload.
62#
63#   -c ConfigFile       file with mmfs.cfg parameters; see mmfs.cfg.sample
64#                       in /usr/lpp/mmfs/samples
65#
66#
67# Obsolete but still supported options:
68#
69#   -n NodeFile         specifies a file of node descriptors that detail the
70#                       node interfaces making up the GPFS cluster
71#
72# Each node descriptor has the format:
73#
74#   nodeName:nodeRoles:adminNodeName:
75#
76# where:
77#
78#   nodeName        is either a short or fully-qualified hostname,
79#                   or an IP address for the primary GPFS network
80#                   to be used for daemon to daemon communications
81#
82#   nodeRoles       is a '-' separated list of node roles.  Unless changed
83#                   on the mmconfig or mmaddnode commands, these roles will
84#                   be associated with the node when it becomes a member of
85#                   a nodeset.
86#
87#   adminNodeName   is either a short or fully-qualified hostname, or an IP
88#                   address to be used by the admin scripts to communicate
89#                   between nodes.  This is an optional parameter; if it
90#                   is not specified, the nodeName value is used.
91#
92# Undocumented options:
93#
94#   -t ClusterType  specifies the cluster type for this cluster
95#                   (supported values are "lc" and "single").
96#                   See note below for additional information.
97#
98#     The format of the -t parameter is ClusterType[/EnvironmentType]
99#     where "ClusterType" is the GPFS cluster type as defined above.
100#     The optional "EnvironmentType" designates the environment within
101#     which the GPFS cluster is being created.  The following table
102#     shows the allowed values.
103#
104#       ClusterType  EnvironmentType  Remarks
105#
106#          lc           lc2           true loose cluster; no RSCT
107#
108#          lc           lc            old style Linux only loose cluster;
109#                                     RSCT subsystem is controlled by GPFS;
110#                                     this combination is no longer allowed
111#
112#          single       single        single node environment
113#
114# Notes:
115#
116#   - Nodes are designated as quorum or non-quorum nodes when they
117#     are added to the cluster (mmcrcluster, mmaddnode).
118#
119#   - The quorum designation can be changed with mmchconfig.
120#
121#   - It is not allowed to change (or delete from the cluster)
122#     the last quorum node.
123#
124#   - If VSD-based disks will be used, all AIX nodes must belong to
125#     an RSCT peer domain.  VSD disks will not be visible to nodes
126#     that do not belong to the RSCT peer domain.  This rule cannot
127#     be enforced by mmcrcluster or mmaddnode.
