[Zenoss-dev] Re: lookupSchema

[Erik A. Dahl]

I can dive into the details of making a relationship with you but  
before we get too far I think you need to take a look at the DeviceHW  
harddisks relationship.  I think that's what you are looking for.  In  
the modeler look at the InformantHardDiskMap.py for an example of how  
to map the object.  Your path should be something like.

device.hw.harddisks.sd0
