Company.com has a non-IBM disk storage unit connected by two Fibre channel connections. The  Nodes have multiple connections to the storage device that allow load balancing. A failure with one Fibre adapter or connection will not be noticed by the application， but it needs to be addressed.  How can HACMP help make this environment more robust？（）  

• A、 Customize disk heartbeat methods to detect disk adapter failures.
• B、 Customize an error notification method that monitors for volume group quorum loss.
• C、 Customize an error notification facility to act on the event when reported to the error log.
• D、 Customize a HACMP event script to monitor the disk connections and cause a fallover if there is a failure.
