Identify Failed Mount Exchanges

Use the Exchanges Overview and SNMP messages to identify failed mount exchanges. A failed mount could indicate an issue with the media or drive.

Use a filter on the Exchanges Overview page to identify failed mounts. STA identifies the first failed mount exchange and filters out any repeat mount failures to prevent reporting multiple repeat errors caused by clients retrying. As a result, you must look at the SNMP messages to identify repeat mount failures.
