19# Usage:  mmdelnode {-a | -f | -N {Node[,Node...] | NodeFile | NodeClass}}
20#
21# where:
22#
23#   -a                 specifies that all of the nodes in the cluster
24#                      are to be deleted.
25#
26#   -N Node,Node,...   Specify the nodes to be deleted from the cluster.
27#   -N NodeFile        NodeClass may be one of several possible node classes
28#   -N NodeClass       (e.g., quorumnodes, managernodes, nsdnodes, etc.)
29#                      If none of -N, -n, or nodelist is not specified,
30#                      the entire cluster is changed; otherwise, the changes
31#                      are made to the specified nodes.
32#                      -N cannot be specified with the obsolete -n options.
33#
34# Obsolete but still supported options:
35#
36#   -n Node,Node,...   is a comma-separated list of nodes to be deleted
37#                      from the cluster.
38#
39#   -n NodeFile        is a file containing the names of the nodes
40#                      to be deleted from the current GPFS cluster.
41#
42# Undocumented option:
43#
44#   -f                 remove all GPFS configuration files on the node.
45#                      This option applies only to the node on which
46#                      the mmdelnode command is issued.

267# the GPFS system files are up-to-date and will obtain the sdr lock.
268#
269# Note:  We are using a variation of gpfsInit - gpfsInitGeneric,
270# which allows the command to still run on old GPFS cluster types.
271# If the cluster type is lc or single, things work as they always do.
272# But if the cluster type is sp, rpd, or hacmp, we are dealing with
273# an obsolete GPFS cluster environment.  The daemon will never be
274# allowed to start under these circumstances, nor will the bulk of
275# the mm commands be allowed to work.  The only exception are commands
276# (mmexportfs, mmdelnode) needed by the user to migrate to a supported
277# environment.  Under such conditions it is acceptable to assume that
278# the daemon is indeed not runing anywhere (i.e., there is no need to
279# run verifyDaemonInactive) and to ignore the true commit processing
280# and the rebuilding of the mmfs environment.  The idea is to allow
281# the user to run "mmexportfs all", followed by "mmdelnode -a", and
282# then create a new cluster of type lc.
