other source. Go to

errors. Due to a limitation of the Windows miniport driver interface, the miniport
can log only two 32-bit values for any event. Information about interpreting these
event codes is in the eventlog.txt file, which is shipped with the miniport
driver.
In addition, the miniport driver can be configured to perform extended event
logging for an HBA, which causes it to log all loop transitions and many minor
events. Extended Application Event Logging uses extra overhead and is enabled
only in troubleshooting situations. The extended Application Event Logging flag is
stored in the HBA NVRAM and can be modified using Fast!UTIL or SANsurfer FC
HBA Manager.

Linux Messages File

For Red Hat/SuSE Linux systems, the Linux messages file is the main source of
information for device driver problems and events. Device drivers usually indicate
only status by logging events in the Linux messages file. SANsurfer FC HBA
Manager agents also use the Linux messages file to report service errors, and so
on. For more information, see the SANsurfer FC HBA Manager help system.
The Linux agent logs events for significant driver errors. In addition, the Linux
agent can be configured to perform extended event logging for an HBA, which
causes it to log all loop transitions and many minor events. Extended Application
Event Logging uses extra overhead and is enabled only in troubleshooting
situations. The extended event logging flag is stored in the HBA parameters and
can be modified using Fast!UTIL or SANsurfer FC HBA Manager.
The path for the Linux messages file is /var/log/messages.
