delete_pool not working

Excuse my ignorance, but I have only been working with an F5 now for a total of about 6 days. I use the following code to create the pool in the first place. I am setting a LocalLBMethod and a LocalLBMonitorRule. Do I need to somehow unlink/delete them first?

 

 

 

// The following line is how you create an empty pool without members.

 

iControl.CommonIPPortDefinition[][] member =

 

new iControl.CommonIPPortDefinition[1][0];

 

 

iControl.LocalLBLBMethod lb_method =

 

iControl.LocalLBLBMethod.LB_METHOD_ROUND_ROBIN;

 

iControl.LocalLBLBMethod[] lbMethods = new iControl.LocalLBLBMethod[]{lb_method};

 

 

lblpool.create(new String[]{poolName}, lbMethods, member);

 

 

// Now set a default monitor association

 

iControl.LocalLBMonitorRule monitorRule = new iControl.LocalLBMonitorRule();

 

monitorRule.setMonitor_templates(new String[]{"gateway_icmp"});

 

 

monitorRule.setType(LocalLBMonitorRuleType.MONITOR_RULE_TYPE_SINGLE);

 

iControl.LocalLBPoolMonitorAssociation monitorAssociation =

 

new iControl.LocalLBPoolMonitorAssociation();

 

monitorAssociation.setPool_name(poolName);

 

monitorAssociation.setMonitor_rule(monitorRule);

 

iControl.LocalLBPoolMonitorAssociation[] monitorAssociations =

 

new iControl.LocalLBPoolMonitorAssociation[]{monitorAssociation};

 

lblpool.set_monitor_association(monitorAssociations);
