19# Usage:
20#
21#   mmaddnode -N {NodeDesc[,NodeDesc...] | NodeFile}
22#
23# where:
24#
25#   -N NodeDesc,NodeDesc,...  specifies a comma-separated list of node
26#                             descriptors that detail the node interfaces
27#                             to be added to the cluster.  The nodes must not
28#                             presently belong to the cluster.
29#
30#   -N NodeFile    specifies a file of node descriptors that detail
31#                  the node interfaces to be added to the cluster.
32#                  The nodes must not presently belong to the cluster.
33#
34# Obsolete but still supported options:
35#
36#   NodeDesc,NodeDesc,...   specifies a comma-separated list of node
37#                           descriptors that detail the node interfaces
38#                           to be added to the cluster.  The nodes must not
39#                           presently belong to the cluster.
40#
41#   -n NodeFile    specifies a file of node descriptors that detail
42#                  the node interfaces to be added to the cluster.
43#                  The nodes must not presently belong to the cluster.
44#
45# Each node descriptor has the format:
46#
47#   nodeName:nodeRoles:adminNodeName:
48#
49# where
50#
51#   nodeName        is either a short or fully-qualified hostname,
52#                   or an IP address for the primary GPFS network
53#                   to be used for daemon-to-daemon communications.
54#
55#   nodeRoles       is a '-' separated list of node roles.  Unless changed
56#                   on the mmconfig or mmaddnode commands, these roles will
57#                   be associated with the node when it becomes a member of
58#                   a nodeset.
59#
60#   adminNodeName   is either a short or fully-qualified hostname, or an IP
61#                   address to be used by the admin scripts to communicate
62#                   between nodes.  This is an optional parameter; if it
63#                   is not specified, the nodeName value is used.
