On the development database rac0, there are six raw devices: /dev/raw/raw1 through
/dev/raw/raw6. /dev/raw/raw1 and /dev/raw/raw2 are 8GB each, and the rest are 6GB each. An
existing disk group +DATA1, of NORMAL REDUNDANCY, uses /dev/raw/raw1 and /dev/raw/raw2.
Which series of the following commands will drop one of the failure groups for +DATA1, create a
new disk group +DATA2 using two of the remaining four raw devices, and then cancel the drop
operation from +DATA1?
A.
ALTER DISKGROUP DATA1 DROP DISK DATA1_0001;CREATE DISKGROUP DATA2
NORMAL
REDUNDANCY FAILGROUP DATA1A DISK �/dev/raw/raw3� FAILGROUP DATA1B DISK
�/dev/raw/raw4�;ALTER DISKGROUP DATA1 UNDROP DISKS;
B.
