Your question isn't clear. Are you running TVHeadend on the same device as the Kodi frontend, or a separate device?
It sounds like you want to record to storage on the frontend device - if this isn't what you want, maybe you should reword your question to make this clearer.
If you're running TVheadend on the same device as the Kodi frontend, then as Mark says, just mount the storage on that device, and configure TVHeadend to use it.
However if you're running TVHeadend on a separate device, then TVHeadend will record to storage on the device it's running on, not on whatever device you happen to be using as the frontend.
