7. Select the type of usage metric to monitor from the Alert Definition drop-down menu.
8. (Optional) To assign the threshold definition to all of the storage objects that are of the type specified in the Alert Object Type,
select the All Objects check box.
The All Objects setting cannot be modified after the threshold definition is created.
9. Specify the alert notification settings for the Error, Warning, and Inform thresholds:
• Error Settings: Enter the threshold value that the usage metric must exceed to trigger an Error threshold alert. To email Error
threshold alerts to the Storage Manager administrators, select the Email check box. Then enter the number of concurrent events
that must occur to trigger an alert email.
• Warning Setting: Enter the threshold value that the usage metric must exceed to trigger a Warning threshold alert. To email
Warning threshold alerts to the Storage Manager administrators, select the Email check box. Then enter the number of
concurrent events that must occur to trigger an alert email.
• Inform Settings: Enter the threshold value that the usage metric must exceed to trigger an Inform threshold alert. To email
Inform threshold alerts to the Storage Manager administrators, select the Email check box. Then enter the number of concurrent
events that must occur to trigger an alert email.
NOTE: Storage Manager sends only one threshold alert email for every 24-hour period. The number of threshold
alert emails per 24-hour period cannot be configured. In addition, if the metric remains at or above the threshold
alert value, a second alert email is not sent. The metric must fall below the threshold value and then exceed the
threshold again to generate an alert email.
10. (Optional) To configure the threshold definition to generate Volume Advisor recommendations to move one or more volumes to a
different Storage Center, select the Recommend Storage Center check box.
• Recommendations are generated when the error threshold is exceeded.
• The Recommend Storage Center checkbox is available only for threshold definitions that support Volume Advisor.
11. To specify the time that Storage Manager monitors the threshold definition:
a) Select the Time Constraint check box.
b) Specify the start of the time period in the Start Time field.
c) Specify the end of the time period in the End Time field.
12. To specify which days of the week that Storage Manager monitors the threshold definition:
a) Select the Day Constraint check box.
b) Select the check boxes of the days of the week to monitor the threshold definition.
c) Clear the check boxes of the days of the week to not monitor the threshold definition.
13. Select the storage objects to assign to the threshold definition in the Add Objects dialog box. Additional objects can be added to a
threshold definition after it is created.
14. Click Finish.
