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.
