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.
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.
