Verify an error occurs if a ctdb command is run against a node without a ctdbd.
That is, check that an error message is printed if an attempt is made
to execute a ctdb command against a node that is not running ctdbd.
Prerequisites:
* An active CTDB cluster with at least 2 active nodes.
Steps:
1. Verify that the status on all of the ctdb nodes is 'OK'.
2. Shutdown ctdb on a node using 'ctdb shutdown -n <node>'.
3. Verify that the status of the node changes to 'DISCONNECTED'.
4. Now run 'ctdb ip -n <node>' from another node.
5. Verify that an error message is printed stating that the node is
disconnected.
6. Execute some other commands against the shutdown node. For example,
disable, enable, ban, unban, listvars.
7. For each command, verify that an error message is printed stating
that the node is disconnected.
Expected results:
* For a node on which ctdb is not running, all commands display an
error message stating that the node is disconnected.
