Consider the following command to add a new disk group called "tdgroupA" with two failover groups： CREATE DISKGROUP tdgroupA NORMAL REDUNDANCY FAILOVERGROUP control01 DISK ’/devices/A1’， ’/devices/A2’， ’/devices/A3’ FAILOVERGROUP control02 DISK ’/devices/B1’， ’/devices/B2’， ’/devices/B3’m The disk "/devices/A1" is currently a member disk of a disk group by the name "tdgroup1". Which task would be accomplished by the command？（）A、 This command would result in an error because a disk group can have only one failover group.B、 This command would result in an error because the /devices/A1 disk is a member of another disk group tdgroup1.C、 A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk will get reattached to the new disk group without being detached from the existing one.D、 A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk will be ignored for the new disk group because it is a member of an existing disk group tdgroup1.E、 A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk gets detached from the existing disk group tdgroup1 and attached to the new disk group tdgroupA
