Returns the status of each cluster node by interrogating the coordinator.

sList is string
sName is string
nStatus is int

sList = HClusterNodeInfo("clustermanager.mydomain.com", "secret")
FOR EACH STRING sNode OF sList SEPARATED BY CR
sName = ExtractString(sNode, 1)
nStatus = ExtractString(sNode, 2)

SWITCH nStatus
CASE 0
Trace("The status of the node " + sName + ...
" is unknown.")
CASE 1
Trace("The node " + sName + ...
" is stopped.")
CASE 2
Trace("The node " + sName + ...
" is ready to be started.")
CASE 3
Trace("The node " + sName + ...
" is being started.")
CASE 4
Trace("The node " + sName + ...
" is waiting for a source of synchronization.")
CASE 5
Trace("The node " + sName + ...
" is being synchronized.")
CASE 6
Trace("The node " + sName + ...
" is enabled.")
CASE 7
Trace("The node " + sName + ...
" is being stopped.")
CASE 8
Trace("The node " + sName + ...
" could not be defined.")
OTHER CASE
Trace("The node " + sName + ...
" has an unknown status (" + nStatus + ")")
