After operations complete, you can click an operation name link to view log files and any error messages generated on the selected host.
Optionally, click a host name link to view tasks on that host.
Optionally,click a task name link to view the task log generated during the operation.
You can use the Copy, Open, or Host Logs icons located at the upper-right of the [HOST_NAME] dialog to copy, open, or view log information generated during the operation.
