Hello John A steady green flashing status light indicates a rebuild. It is possible that someone reconfigured the array and it is rebuilding the entire array into the new configuration, but you would likely be aware of something like that taking place. I am going to need to look at a controller log to find out what is going on. If you want to post a log somewhere and link to it I will review it. Thanks
Hi, One of our R720XD's has constantly flashing lights on all disks. i.e. Both lights on every disk are constantly flashing in unison. All 23 disks are doing the same thing. It is running Server 2012 and the o/s seems ok.  The disks start flashing just after the bios kicks in with the raid controller, i.e. well before Windows starts We have other r720xd's where the disk activity is quite normal. The DRAC logs are not indicating any problem, yet it is obviously not normal behaviour.  Any ideas how to troubleshoot this? Thx, John Bradshaw
