Company.com needs to add a new file system to an existing volume group that is being made  Highly available by HACMP？ What is the best procedure that minimizes down time of the applications？（）  

• A、 Use C-SPOC to add the file system while the cluster is running.
• B、 Add the file system，and them perform the exportvg and importvg on the required nodes.
• C、 Stop the cluster，add the new file system， and synchronize the cluster then restart HACMP.
