The svcs -x command with no service name shows any services that are in the maintenance state. Use the svcs command on all OpenStack nodes to ensure that all required services are in the online state. If a required service is not in the online state, check log files as discussed in Examining Log Files.
For general help fixing problems with SMF services, see Troubleshooting Services Problems in Managing System Services in Oracle Solaris 11.2 .
If your problem might be a network issue, run the evsadm command on all nodes.
If you have problems successfully completing an operation while using the OpenStack dashboard, try the same operation on the command line. You might receive a more helpful error message on the command line. Check whether the command has a verbose output option.
If you are having a problem in a node other than the Controller node, run some simple commands such as nova list on the command line on that node to verify that the node is able to communicate with the Controller node.
