’/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.
