Hardware environment: a DELL server T430 (dual C/16G/4 block 300G / H310 array cards, RAID5)

Software environment: there is a certain version of Server operating system and financial software.

The problem that needs to be solved: the server can not boot into the system, and the company's financial data is at risk of loss. Can the data be recovered?

The author's idea: when we encounter that the DELL server (existing operating system) can not enter the system, we need to consider two reasons: a. The operating system startup item file is missing because the server has been poisoned and has been suddenly powered off while the server is running. b. The server hard drive is broken or offline. Is it offline or really broken? If it is broken, there will generally be an error message, and the hard disk itself flashing lights is not normal. Wait. If it is offline, then the significance of writing this article now exists.

1. The current state of the DELL server T430 is that when powered on and turned on, the server flashes normally, but it cannot enter the operating system. See figure 1

At this time, the server is cycling all the time, and it doesn't work to connect F1.

So, we want to see if this machine raid card interface can be accessed, so restart and prepare to enter the raid card interface, figure 2

Don't tell me, you don't know how to get into the RAID interface, my sister only said it once: press CTRL+R at the prompt

two。 As long as you can get into the RAID interface, there is hope. What if the interface we see is in the case of figure 3?

Congratulations, 4 hard drives, 2 are not in the RAID group, at this time, we want to know, in the end what is the situation, to CTRL+N, to observe more data? See figure 4

Obviously, there are two hard drives foreign, which is not bad. We go back to the RAID interface, and move the cursor over the array card, press F2, we can see that there is a white option, we want to select Foreign Config, and select Import, see figure 5

The author reminds, do not choose wrong oh, a misstep data is finished, it is better to have professional guidance to complete it.

When we have finished selecting, we can see a normal RAID interface, as shown in figure 6

The RAID5 is normal, and you can see that the next 4 hard drives in the group are still in the RAID group.

We can quit and restart the machine.

3. At this time, we can be pleasantly surprised to find that our DELL server is normal and can enter the operating system, as shown in figure 7

Let's quickly enter the operating system and back up the data in the server.

DELL server is not difficult to operate, but it is a mainstream choice in many brands. Here, I would like to share another picture, the internal structure of the DELL EMC R740XD storage server, as shown in figure 8

DELL14 agent server can ask me for more choices. In addition, GPU server, is not also the current friends want to know the content, I also have a lot to share.
