How to use pyControl to retrieve Failover.UnitId?

Hi Linda: looking at the iControl SDK it looks like you need to pass a keyword argument to this method. Here's the correct syntax:

 
 In [4]:  b.Management_DBVariable.query(variables = ['Failover.UnitID']) 
 Out[4]: {'return': [{'name': 'Failover.UnitID', 'value': '1'}]} 
 

Also, when in question, you can print a hidden variable for any method, '_h', which will give you a hint as to parameters:

 
 In [6]: print b.Management_DBVariable.query._h 
 InParams Count: 1 
 variables:              Common.StringSequence 
 OutParams Count: 1 
 return:         Management.DBVariable.VariableNameValueSequence 
 

I hope this helps,
