Working With Command History Logs
The Command History Log dialog box enables you to view command
and response activity that has occurred with externally addressable
library devices, including the LMC, controller LUNs, partitions, and
drives. This information can help you isolate the source of an issue, such
as a library device or host application.
The number of selected drives affects the
performance of the Command History Log.To
ensure proper operations, limit drive log requests
to twenty-five.
