	19	# Usage: mmchconfig Attribute=value[,Attribute=value...] [-i \| -I]
	20	# [-N {Node[,Node...] \| NodeFile \| NodeClass}]
	21	#
	22	# where
	23	# -i specifies immediate. The change takes place immediately, not
	24	# just on the next restart. This is currently only valid with
	25	# a subset of config attributes.
	26	#
	27	# -I specifies immediate ONLY. The change takes place immediately
	28	# and does not have any effect on the next restart.
	29	# This is currently only valid with a subset of config attributes.
	30	#
	31	# -N Node,Node,... Specify the nodes whose states are to be changed.
	32	# -N NodeFile NodeClass may be one of several possible node classes
	33	# -N NodeClass (e.g., quorumnodes, managernodes, nsdnodes, etc.)
	34	# If none of -N, -n, or nodelist is specified, the entire
	35	# cluster is changed; otherwise, the changes are made to
	36	# the specified nodes.
	37	# Do not use -N to do an update to an omitted node as the
	38	# output is not the same as running without nodefile.
	39	# -N cannot be specified with the obsolete -n or nodelist
	40	# options.
	41	#
	42	# Obsolete but still supported options:
	43	#
	44	# -n NodeFile is a file containing a list of nodes.
	45	# If none of -N, -n, or nodelist is not specified,
	46	# the entire cluster is changed; otherwise, the changes
	47	# are made to the specified nodes.
	48	# Do not use -n NodeFile to do an update to an omitted node
	49	# as the output is not the same as running without -n NodeFile.
	50	# -n cannot be specified with -N or nodelist.
	51	#
	52	# nodelist is a list of nodes separated by commas.
	53	# If none of -N, -n, or nodelist is not specified,
	54	# the entire cluster is changed; otherwise, the changes
	55	# are made to the specified nodes.
	56	# Do not use nodelist to do an update to an omitted node
	57	# as the output is not the same as running without nodelist.
	58	# nodelist cannot be specified with -N or -n.
	59	#
	60	# Notes on attributes:
	61	#
	62	# The attributes that can be changed are divided into two main categories:
	63	# - externally-documented attributes
	64	# - internal configuration parameters to be used only under the
	65	# direction of IBM service
	66	#
	67	# The externally-documented attributes are:
	68	#
	69	# pagepool specifies the size of the area in the shared memory
	70	# segment from which buffers are allocated for data
	71	# that is read/written from/to disk.
	72	#
	73	# maxFilesToCache specifies the number of recently used but closed
	74	# files which will have their inodes cached.
	75	#
	76	# maxStatCache number of entries to keep in the stat cache
	77	# files which will have their inodes cached.
	78	#
	79	# dataStructureDump specifies a directory to store dumps. Specify
	80	# 'no' to turn off the feature altogether (no dumps).
	81	# Specify 'yes' to send the dumps to /tmp/mmfs.
	82	#
	83	# unmountOnDiskFail controls how the daemon will respond when
	84	# a disk failure is detected.
	85	#
	86	# dmapiEventTimeout controls the blocking of NFS and DFS threads
	87	#
	88	# dmapiSessionFailureTimeout controls the blocking of file operation
	89	# threads when there is a failure
	90	#
	91	# dmapiMountTimeout controls the blocking of mount operations
	92	#
	93	# autoload controls whether the daemon will start up
	94	# automatically when nodes boot
	95	#
	96	# designation dash-separated list of node roles:
	97	# client, manager, quorum.
	98	#
	99	# uidDomain specifies the UID/GID domain to be used.
	100	#
	101	# automountDir specifies the directory to be used by the Linux
	102	# automounter for GPFS file systems that have the
	103	# automount option specified. The default directory
	104	# is /gpfs/autmountdir. This parameter does not
	105	# apply to AIX environments.
	106	#
	107	# tiebreakerDisks controls whether GPFS will use a node quorum plus
	108	# tiebreaker disks algorithm in place of the regular
	109	# node-based quorum algorithm. The tiebreaker disks
	110	# do not have to belong to any particular file system.
	111	# The disks are specified as a disk list. If there
	112	# are more than one disk, delimit each name with a
	113	# semicolon and enclose the list in quotation marks.
	114	# If "no" is specified, GPFS reverts to the traditional
	115	# node-based quorum algorithm. The disks must be
	116	# directly accessible from the quorum nodes.
	117	#
	118	# maxblocksize max data block size the file system supports
	119	#
	120	# release bring the configuration information for the
	121	# cluster to the latest format version. Set the
	122	# maxFeatureLevel config parameter to the latest
	123	# release level or to the specified level.
	124	#
	125	# allowRemoteConnections controls whether outside nodes can connect
	126	# to nodes in this GPFS cluster. This is a
	127	# global switch in addition to any other security
	128	# mechanism that may be established.
	129	#
	130	# cipherList controls whether GPFS network communication
	131	# between local nodes and remote nodes is secured.
	132	# If cipherList is not specified, or if the value
	133	# DEFAULT is specified, then GPFS will not authenticate
	134	# or check authorization for network connections.
	135	# If cipherList is specified, then it should be a valid
	136	# cipher list as documented by man ciphers(1).
	137	#
	138	# updateDiskType causes the disk subtype information to be reevaluated.
