Hello,   those are normal messages on a controller failover.    Actually, I'm pretty sure I know what the issue is.  That version of firmware I believe is vulnerable to a restart bug after about 200+ days of run time.  It would explain why both rebooted since they likely have near identical run time.  During a failover the up time of the passive isn't reset.   So upgrading the firmware will likely resolve this issue.  Regards, Don   
Earlier I was having issues writing to disk in my VMware environment and received an email notiifcation from SANHQ stating both active and standby controller restarted. I also received a caution that "Controller failed over in member". When I look at the boot time on both controllers from the GUI they both show the same boot time. Does this mean that both controllers rebooted at the same time and if so, what conditions would cause this?
