The dual Xeon cpu 32 GB memory server makes the array 1 after replacing a bad hard disk, no Array

Process summary

1. After a bad hard disk is replaced, the original primary disk becomes invalid after the system recognizes the primary again. If the old disk is inserted into the system at this time, it will become chaotic and cause the system to become inaccessible, it is useless to dial out.

2. The smart error will not be prompted. This time it was an error measured using the system test program (BOOT F10.

3. Two hard disks of different sizes, one 146 GB and the other 300 GB, can be raid 1 (image). Some dell after-sales personnel say no. I have tested it,

4. if you drop the disk when deleting the array, press ctrl + c to go to array management and delete the array. If you drop the disk in advance, you cannot delete the array. If you insert the primary disk again, the array will appear again. This time, the primary disk is allocated first, and the array settings are deleted from the disk ,... Finally, we found that the data from the disk is still there.

The following is a supplement from other netizens:

Assume that RAID 1 is in our group.

1. One of the hard disks has crashed. How can I determine which one has a problem ?!

2. How can I replace the faulty hard disk? Shut down, remove the problematic hard disk, and change it to a new one ?! Does the image disk automatically Resync data ?!

3. Can I use multiple hard disks for group RAID 1.

4. Group RAID 1. Whether two hard disks must be reformatted before they can be used.

5. It is safer to use a array card for RAID chips on the motherboard.

Answer:

1: Check the port number.
2: simply remove the new mountainous area.
3: Unknown
4: No. You can directly set a primary disk, and then automatically mirror the second disk.
5: Hard to say

Troubleshooting for brothers RAID 1 is as follows:
A. first, RAID1 requires two hard disks of the same brand with the same specification. There are two types of faults: Data damage and hardware damage (the hard disk itself is damaged) if it is the former, you can still read the data. You can use it! The latter can be read for two minutes and cannot be read!
B. The simplest way is to remove one of them first and then read whether the other is OK. For example, if OK is removed, it is a problematic hard disk! Test another disk! Is to use exclusion to find! If it is a array box, the disk will be displayed! Now, Intel has a tool to show the health status of the hard drive on the current port. This is more intuitive !!!
C. After you confirm that the disk is damaged, it will be automatically reorganized and repaired after the same hard disk is replaced. the time consumed is related to the hard disk capacity. The larger the capacity, the longer it will take !!

Question 2

Xuefeng975 user's question: There are three hard disks on the computer, one is the system disk, and the other two TBS are RAID 1. Now the array is stuck in the array. How can we restore the data?

York284: the hard disk should be broken. Try a new disk and press the shortcut key to enter RAID management. There is a self-check. Choose to set the backup disk. After the backup disk is created, You Can rebulding it; you can also enter the system, start the Management Program, and enable the program to automatically rebulding. We recommend that the system rebulding itself. During the operation, it is best to perform step-by-step operations on the array card instruction. If you make a mistake, the consequences will be very serious.
Sad reminder, take a place, also want to learn.
Use diskgenius to search for partitions. Data is important. Do not recreate the array.

Question 3

The raid 1 data disk is broken, but can it be attached directly with a new hard disk?

Raid 1 breaks down a hard disk.
REMOVE the bad ones and replace them with the new ones. In the RAID control, ADD/remove spare (ADD idle disk). After the disk is successfully added, the RAID status is rebuild.

Question 4

A computer uses a RAID card for RAID1 and cannot be started now. Is there any way to read the data on the hard disk?

Well, I tried it just now. Sure you can! That is to say, after RAID1 is completed, two hard disks can be read by directly inserting them into the computer?

Question 5

Can raid1 work with a hard disk? I don't know how to create a raid volume. How can I name one disk as raid?

First of all, the principle of raid1 is that two hard disks synchronize data. Simply put, they are images of each other. If one hard disk cannot work
Raid1 the meaning of raid1 is lost when I break down a disk and discard the entire array.
So one disk can work, and I tried it on intel's raid chip.
