What is the net effect of the following command?
alter diskgroup dgroup1 drop disk abc;
A.
The disk ABC will be dropped from the disk group. Since you did not issue a rebalance
command, the data on that disk will be lost.
B.
The command will raise an error indicating that you need to rebalance the disk group to
remove the data from that disk prior to dropping the disk.
C.
The disk group will be automatically rebalanced during the drop operation. Once the
rebalancing is complete, the disk will be dropped.
D.
This command will fail because you cannot drop a specific disk in an ASM disk group.
E.
The disk drop command will be suspended for a predetermined amount of time, waiting
for you to also issue an alter diskgroup rebalance command. Once you have issued the
rebalance command, ASM will proceed to rebalance the disk group and then drop the disk.
Always a massive fan of linking to bloggers that I like but do not get a great deal of link enjoy from.
C
When a disk is dropped, the disk group is rebalanced by moving all of the file extents from the dropped disk to other disks in the disk group. A drop disk operation might fail if not enough space is available on the other disks.
