You are managing an Oracle Database 11g ASM instance having three disks in a disk group
with ASM compatibility attribute set to 11.1.0 and redundancy set to high. One of the disks in
the disk group becomes unavailable because of power failure.
Which statements will be true in this scenario? (Choose all that apply.)
A.
The disk is immediately dropped from the disk group.
B.
The ASM tracks the extents that are modified during the outage.
C.
The ASM migrates the extents from the unavailable disk to the remaining disks.
D.
The disk automatically goes offline.
Answer C is wrong because it will not “migrate” or better said “rebalance” until the disk is ONLINE again, or is replaced.
Answer A is wrong because the disk is not immediatly dropped from the disk group. This would probably happen after DISK_REPAIR_TIME disk group attribute.
