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 “debug” 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 Table 13.
