RE: Raid - 5 Fail, Can't Run OS
The hard drive is likely to be in predictive failed state. Check the status of the drive in OpenManage Server Administrator, OMSA if installed or boot into the controller BIOS using Ctrl+R during POST. If in the predictive fail state, offline the and replace with another one.
Thanks for responding my case. i have another question, when we use raid it means the data shared and being backed up right? is there any chance my data is ok? or maybe i should do rebuild raid from begining?
