and open Web Tools again.
To initiate a nondisruptive failover, perform the following steps.
1. Open the High Availability window.
2. Verify that the HA Status field displays HA enabled, Heartbeat Up, HA State synchronized or HA
enabled, Heartbeat Up, HA State not in sync.

The Warning dialog box displays.
4. Click Yes to initiate a nondisruptive failover.

open Web Tools.
Event monitoring
Web Tools displays fabric-wide and switch-wide events. Event information includes sortable fields for
the following:
• Switch name
• Message number
• Time stamp
• Indication of whether the event is from a logical switch or a chassis
• The number of successive events of the same kind
• Severity level
• Unique message identifier (in the form moduleID -messageType)
• Detailed error message for root cause analysis
There are six message severity levels:
• Critical
• Alert
• Error
• Warning
• Information
• Debug
The following table lists the event message severity levels displayed on the Switch Events tab and
explains what qualifies event messages to be certain levels.
