hy,
I'm configuring a set of 5 servers to replace an industrial SCADA system.
Today we finally received the extra RAM sticks we ordered, to install those I powered down the servers and installed the RAM, no problem until the last server where I think the system wasn’t (completely) powered down. so probably I just unplugged it while still running (Only realized it afterwards).
Now when I try to boot the system I will get the following screen (see attachment) telling me: "The drive where Windows is installed is locked. Unlock the drive and try again".
It seems like the drive is inaccessible, but the smart storage administrator doesn’t seem to give any errors or warnings.
I tried sfc /scannow and it told me it repaired some files but it didn’t solve the problem (did it have access to de drive somehow?)
Also unplugging one of the drives doesn’t seem to help, it recognizes the failed (unplugged) drive but still can't boot.
I guess it has something to do with the raid, but I’m not very experienced with this, so to not unrecoverable break the install I'm here to ask for help.
I really would like to not reinstall because it will involve getting the SCADA license renewed and based upon how long those guys take for basically anything it will cost us even more time we don't have.
I hope I have given enough information and someone has the solution, but feel free to ask for more details!
