Implementation Reference
- The main handler function decorated with @tool_handler that executes the create_iscsi_target tool. It generates an IQN, prepares target data, calls the TrueNAS API to create the target, and returns success response with next steps.async def create_iscsi_target( self, name: str, alias: Optional[str] = None, mode: str = "ISCSI", auth_networks: Optional[List[str]] = None ) -> Dict[str, Any]: """ Create an iSCSI target Args: name: Target name (will be part of IQN) alias: Optional alias for the target mode: Target mode (ISCSI or FC) auth_networks: List of authorized networks Returns: Dictionary containing created target information """ await self.ensure_initialized() # Generate IQN from datetime import datetime year_month = datetime.now().strftime("%Y-%m") iqn = f"iqn.{year_month}.com.truenas:{name}" target_data = { "name": iqn, "alias": alias or name, "mode": mode, "groups": [] } # Create auth group if networks specified if auth_networks: # This would require creating an auth group first # For now, we'll note this in the response pass created = await self.client.post("/iscsi/target", target_data) return { "success": True, "message": f"iSCSI target '{name}' created successfully", "target": { "id": created.get("id"), "iqn": created.get("name"), "alias": created.get("alias") }, "next_steps": [ "Create an extent (LUN) for this target", "Map the extent to this target", "Configure initiator groups if needed", "Enable iSCSI service if not already enabled" ] }
