Question
An ASM diskgroup that contains database tablespaces with six disks and normal redundancy is nearing 90% capacity. You want to add additional capacity to the diskgroup. A set of six additional disks has been made available, and appears as CANDIDATE disks in the V$ASM_DISK view. What steps are required to increase the diskgroup capacity?
Options
- AExport the database objects.
- BShut down the database instances using the diskgroup.
- CSet the rebalance power limit (or allow it to default).
- DShut down all database instances and ASM instances.

Explanation
You can use the ADD clause of the ALTER DISKGROUP statement to add a disk or a failure group to a disk group. The same syntax that you use to add a disk or failure group with the CREATE DISKGROUP statement can be used with the ALTER DISKGROUP statement. ASM automatically rebalances the disk group when disks are added. By default, the ALTER DISKGROUP statement returns immediately after the disks have been added while the rebalance operation continues to run asynchronously. You can query the V$ASM_OPERATION view to monitor the status of the rebalance operation. Oracle 11g: RAC and Grid Infrastructure Administration Accelerated 8 - 21
