B.) Error Log Capabilities 

 
The ATTO Celerity FC host adapter driver logs all failure related information to an 
event log.  The user can control the classification of events that are recorded via a 
registry setting for Windows. 
 

The driver records events broken into the following classifications. 

  FATAL 

Records various fatal situations within the driver and card. 

  FIBRE  

Records FIBRE errors as reported by the card. 

  ISP 

 

Records errors as reported by the firmware of the card. 

  LOOP  

Records event notifications as reported by the firmware. 

  INFO   

Records events related to the starting and restarting of the 

driver. 

 
We recommend Event Logging only be active for troubleshooting purposes as 
performance will be affected and that when in this mode of operation, all flags be 
enabled.
