usage: clusvcadm [command]
Resource Group Control Commands:
  -v                     Display version and exit
  -d <group>             Disable <group>.  This stops a group
                         until an administrator enables it again,
                         the cluster loses and regains quorum, or
                         an administrator-defined event script
                         explicitly enables it again.
  -e <group>             Enable <group>
  -e <group> -F          Enable <group> according to failover
                         domain rules (deprecated; always the
                         case when using central processing)
  -e <group> -m <member> Enable <group> on <member>
  -r <group> -m <member> Relocate <group> [to <member>]
                         Stops a group and starts it on another
                         cluster member.
  -M <group> -m <member> Migrate <group> to <member>
                         (e.g. for live migration of VMs)
  -q                     Quiet operation
  -R <group>             Restart a group in place.
  -s <group>             Stop <group>.  This temporarily stops
                         a group.  After the next group or
                         or cluster member transition, the group
                         will be restarted (if possible).
  -Z <group>             Freeze resource group.  This prevents
                         transitions and status checks, and is
                         useful if an administrator needs to
                         administer part of a service without
                         stopping the whole service.
  -U <group>             Unfreeze (thaw) resource group.  Restores
                         a group to normal operation.
  -c <group>             Convalesce (repair, fix) resource group.
                         Attempts to start failed, non-critical
                         resources within a resource group.
Resource Group Locking (for cluster Shutdown / Debugging):
  -l                     Lock local resource group managers.
                         This prevents resource groups from
                         starting.
  -S                     Show lock state
  -u                     Unlock resource group managers.
                         This allows resource groups to start.

[root@essun html]# cman_tool -h
Usage:
cman_tool <join|leave|kill|expected|votes|version|wait|status|nodes|services|debug> [options]
Options:
  -h               Print this help, then exit
  -V               Print program version information, then exit
  -d               Enable debug output
join
  Cluster & node information is taken from configuration modules.
  These switches are provided to allow those values to be overridden.
  Use them with extreme care.
  -m <addr>        Multicast address to use
  -v <votes>       Number of votes this node has
  -e <votes>       Number of expected votes for the cluster
  -p <port>        UDP port number for cman communications
  -n <nodename>    The name of this node (defaults to hostname)
  -c <clustername> The name of the cluster to join
  -N <id>          Node id
  -C <module>      Config file reader (default: xmlconfig)
  -w               Wait until node has joined a cluster
  -q               Wait until the cluster is quorate
  -t               Maximum time (in seconds) to wait
  -k <file>        Private key file for Corosync communications
  -P               Don‘t set corosync to realtime priority
  -X               Use internal cman defaults for configuration
  -A               Don‘t load openais services
  -D<fail|warn|none> What to do about the config. Default (without -D) is to
                   validate the config. with -D no validation will be done.
                   -Dwarn will print errors but allow the operation to continue.
  -z           Disable stderr debugging output.
wait               Wait until the node is a member of a cluster
  -q               Wait until the cluster is quorate
  -t               Maximum time (in seconds) to wait
leave
  -w               If cluster is in transition, wait and keep trying
  -t               Maximum time (in seconds) to wait
  remove           Tell other nodes to ajust quorum downwards if necessary
  force            Leave even if cluster subsystems are active
kill
  -n <nodename>    The name of the node to kill (can specify multiple times)
expected
  -e <votes>       New number of expected votes for the cluster
votes
  -v <votes>       New number of votes for this node
status             Show local record of cluster status
nodes              Show local record of cluster nodes
  -a                 Also show node address(es)
  -n <nodename>      Only show information for specific node
  -F <format>        Specify output format (see man page)
services           Show local record of cluster services
version
  -r               Reload cluster.conf and update config version.
  -D <fail,warn,none> What to do about the config. Default (without -D) is to
                   validate the config. with -D no validation will be done. -Dwarn will print errors
                   but allow the operation to continue
