Apple Xsan 2 - Manual (Page 126)

If a volume unexpectedly restarts
Xsan can restart a volume for a variety of reasons, including controller restart and
volume failover. The notification is the same in all cases, but you can examine the log
files for more details.
View the logs:
1 Open Xsan Admin and click the Logs button at the top of the window.
2 In the Logs window that appears, use the Computer and Log pop-up menus to
choose a log.
