I have install two open-E server last year ( fail-over )
But since the installation, the primary server crashed once a month on average ( crash and reboot )
I have updated the firmware to :
6.0up90.xxxx.5845 2011-11-03 b5845.1
but it did not resolve this bug
this is not a Raid error , i have no alert on raid utility ( 3ware 9650SE-12ML)
