Implement volume failover

Implement volume failover by specifying backup volume servers using the priority= attributes of resource and filestoregroup elements of the fsc and loadbalancer elements in the fmsmaster_fscid.xml file. The priority= attributes on a number of other elements in the fmsmaster_fscid.xml file affect the failover characteristics of request routing, including: The assignedfsc elements of clientmap elements, particularly when the assignedfsc element refers directly to volume servers. The resource and filestoregroup elements of fsc and loadbalancer elements, which apply most directly to the selection of target resource servers for FMS routing. The entryfsc elements of fscgroup elements, particularly when the entryfsc element refers directly to volume servers. The exitfsc elements of fscgroup elements, particularly when the exitfsc element refers directly to volume servers. The fscimport elements of defaultfscimport elements, particularly when the fscimport elements refer directly to volume servers in the fmsmaster_fscid.xml configuration file of the external fmsenterprise element.
