91. Consider the following command to add a new disk group called "td
groupA" 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 failov
er groups and the /devices/A1 disk will get reattached to the new dis
k group without being detached from the existing one.
D. A new disk group called tdgroupA will be added with two failov
er groups and the /devices/A1 disk will be ignored for the new disk g
roup because it is a member of an existing disk group tdgroup1.
E. A new disk group called tdgroupA will be added with two failov
er groups and the /devices/A1 disk gets detached from the existing di
sk group tdgroup1 and attached to the new disk group tdgroupA.
