Disk Maximum Used (%) with Rebalance is used to determine if a rebalance in progress needs a power boost to complete in a timely manner and prevent other errors from occurring due to space constraints.
The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Increase the rebalance power for Disk Group %diskGroup% because at least one disk is critically low on space. |
For this metric you can set different warning and critical threshold values for each "Disk Group" object.
If warning or critical threshold values are currently set for any "Disk Group" object, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each "Disk Group" object, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
If a rebalance is in progress and the power value is greater than 0, then Disk Maximum Used (%) with Rebalance is calculated as (100 - Actual Minimum Percent Free), 0 otherwise.
A critical alert will be generated if Disk Maximum Used (%) with Rebalance is greater than or equal to 95%. In this case the rebalance power for the disk group must be increased because at least one disk is critically low on space. Increase the rebalance power (maximum power level is 11).
