Thank you for the clarification. It would be very helpful to be able to
monitor disk availability via HR, as opposed to creating a custom probe
to do this.

When InterMapper polls the device using the Host Resources probe, it 
receives information about the storage devices present. If a storage 
device that was present is no longer present for a given number of 
poll cycles, it is aged out of the table, so what you're seeing is 
what was intended.

I can certainly add an enhancement request for the ability to alarm 
on items in the storage table disappearing.
