문제15

The DGRP1 diskgroup has these attributes:
* Normal redundancy
* Two failgroups with four asmdisks in each failgroup
* compatible.asm set to 12.1
The ASM_POWER_LIMIT parameter is currently set to 1 in the ASM instances.
There are three databases whose instances are up and which access data in the DGRP1 diskgroup.
No other clients use this diskgroup.
You want to add two asmdisks to each failgroup, complete the rebalance as quickly as possible, by avoiding checks for access to allocation units, and then restore database availability.
Examine the list of actions (see exhibit):
