ClientRPC running on host, not client. Please help! (Code Included)

Ok so I am working on a game that will have a StorageBox that will have random loot in it. The box works just fine, meaning loot is spawned, populated, etc. Where I got stuck for days is I'm trying to set a variable isBusy on the box so that if a player has it open, other players cannot open it. I'm afraid I may be going about this all wrong, surely it cannot be this hard!

StorageBox is a prefab that has StorageInventory.cs script on it. Player has PlayerMove.cs on it.

Here is the code used: PlayerMove:

     void Update () {    
         if (!isLocalPlayer)
             return;        
         var x = Input.GetAxis("Horizontal")*0.1f;
         var z = Input.GetAxis("Vertical")*0.1f;        
         transform.Translate(x, 0, z);
         RaycastHit hit;
         float theDistance;
 
         Vector3 forward = transform.TransformDirection (Vector3.forward) * 10;
         // E Key Handler
         if (Input.GetKeyDown (inputManagerDatabase.StorageKeyCode)) {
             if (Physics.Raycast (transform.position, (forward), out hit)) {
                 theDistance = hit.distance;
 
                 if (theDistance <= 1.6f && hit.collider.gameObject.tag == "StorageBoxGeneric") {
                     CmdStorageBoxGenericBusy(hit.collider.gameObject);
                 }
             }
         }
         // End E Key Handler
     }
 
 
     [Command]
     void CmdStorageBoxGenericBusy(GameObject g) {
         STI = g.GetComponent<StorageInventory> ();
         if (STI.isBusy == true) {
             STI.CmdSetBusy (false);
             STI.RpcOpenInventoryWithTimer();
         } else {
             STI.CmdSetBusy (true);
             STI.RpcOpenInventoryWithTimer();
         }
     }

StorageInventory:

 public void CmdSetBusy(bool b) {
         isBusy = b;
         showStorage = b;
     }
     [ClientRpc]
     public void RpcOpenInventoryWithTimer() {
         if (showStorage == true && isBusy == true) {
             Debug.Log ("Opening");
             //startTimer = Time.time;
             //showTimer = true;
             //yield return new WaitForSeconds (timeToOpenStorage);
             inv.ItemsInInventory.Clear ();
             inventory.SetActive (true);
             addItemsToInventory ();
             //showTimer = false;
             //if (timer != null)
                 //timer.SetActive (false);
         } else {
             Debug.Log ("Closing");
             storageItems.Clear ();
             setListofStorage ();
             inventory.SetActive (false);
             inv.deleteAllItems ();
             tooltip.deactivateTooltip ();
         }
     }

The problem is when player2 (A client) opens the box, it opens on player1 (The host) screen only. The host can open it fine, but the player cannot.

So I guess the question I have specifically is this: When any player (From the PlayerMove.cs script) sends a [Command] to run code on the server, how can I have that code [ClientRPC] run ONLY on the player that called it? Again I may be going about this all wrong, but I need help please! Thank you!
