I have three identically configured SuperMicro servers, based on their X7DWN+ motherboard (Intel 5400 chipset). This board includes Intel's ESB2 RAID controller. The only difference between these three servers, hardware-wise, is the drive configurations. Each one is Windows 2008 (64-bit), fully patched. Only differences, software-wise, is installed services.
I have successfully updated 3/3 servers from drivers release 8.9 to 9.6.
One of the three will not load the RST GUI due to "RST service not starting". The iastordatamgr service is NOT found in the Services. When comparing the three systems, I see the affected system does not contain the same registry key contents (HKLM\System\CurrentControlSet\Services\iastordatamgrsvc) as the two servers with a successful update. There may be other related differences in the registry, this is the one that's obvious to me.
