关于cluster
Platform                             Command
---------------------------------------
AIX                            HACMP
                                   $ /usr/bin/lssrc -ls grpsvcs
                                   Note: Verify that the CLSTRMGR_cluster_id has number of
                                   providers equal to the number of nodes.      
                                   PSSP 3.4
                                   $ /usr/bin/lssrc -ls hags

                                   should also be a local provider.
HP                              $ /usr/sbin/cmviewcl -v
Linux                          $ ps -efl | egrep ‘watchdogd|oracm’
                                   if all of watchdogd and oracm program appears in the
                                      process list, Oracle Cluster Management Software is running.
                                   if all of watchdogd and oracm program does not appear
                                      in the process list, restart the Oracle Cluster Management Software.
Solaris                         $ ps -ef | grep clustd
                                   if the clustd program appears in the process list, clustd is running.
                                   if the clustd program does not appear in the process list,
                                      restart the Cluster Membership Monitor.
Tru64                          $ /usr/sbin/clu_get_info
                                   Note: Verify that the correct number of cluster members are
                                   configured. Member state for all nodes should be "up".
