Introduction 
The DSAN maintains a log of certain events that occur in the system. You can view 
this event log by retrieving it via TFTP using SNMP. 
The event log cannot be viewed locally at the DSAN. It can only be viewed by 
transferring the log via SNMP and opening the log file with a text editor or 
spreadsheet application. The log file is comma-delimited, so it can be viewed easily 
as a spreadsheet. 
The event log holds up to 3 megabytes of data, which is enough to store over 5,000 
events. If a new event is recorded after the log becomes full, the oldest third of the 
events in the log are removed automatically so that new events can be added. 
To avoid loss of event data, we recommend that the event log be saved and emptied 
before it reaches full capacity. To help manage this activity, several traps are sent to 
indicate that the log is nearing capacity, and one trap is sent to indicate that the log is 
full. 
To save and empty the event log, you first use SNMP to upload the log file from the 
DSAN to a TFTP server. Then, again using SNMP, you clear the event log file on the 
DSAN for new events. 
This chapter describes the event log and provides instructions for uploading and 
clearing the event log using SNMP.
