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

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.

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.

DSAN to a TFTP server. Then, again using SNMP, you clear the event log file on the
