3.1.2 Checking the Status of an ASM Rebalance Operation

You can check the status of an Oracle ASM rebalance operation.

• The rebalance operation may have completed successfully. Check the Oracle ASM alert logs to confirm.

• The rebalance operation may be currently running. Check the GV$ASM_OPERATION view to determine if the rebalance operation is still running.

• The rebalance operation may have failed. Check the V$ASM_OPERATION.ERROR view to determine if the rebalance operation failed.

• Rebalance operations from multiple disk groups can be done on different Oracle ASM instances in the same cluster if the physical disk being replaced contains Oracle ASM disks from multiple disk groups. One Oracle ASM instance can run one rebalance operation at a time. If all Oracle ASM instances are busy, then rebalance operations are queued.

Note:

Starting with Oracle Exadata System Software release 12.1.2.0 and Oracle Database release 12.1.0.2 with BP4, alerts are generated for ASM rebalance operations. In earlier releases, the administrator had to check the status of the operation.
