Debugging 

The following debug commands capture all the support information needed to diagnose suspected 
system issues:

•

portlog
Displays the log of FC frames and other main control messages that were sent out and 
received.

•

portlogclear
Clears the port’s frame log.

•

portlogctl
Enables or disables the portlog.

Refer to 

 on page 135 for details about these commands.

supportSave

The supportSave command collects debug information needed from the driver. You can collect 
supportSave information using the bfa_supportsave command or through the Data Center Fabric 
Manager (DCFM). HCM supportSave contains driver, agent, and HCM-related information.

NOTE

Before collecting data using the supportSave feature, you may want to disable auto-recovery on the 
host system. This is because when adapters are reset after an auto-recovery from a failure, traces 
initiated before the failure can be lost or overwritten.

The captured debug information can be saved to the local filesystem and then sent to the supplier 
for further investigation. The information that is captured is detailed in 

.
