Dual Xeon CPU 32g memory server did array 1 after replacing a bad hard drive, did not do array _ server other

Summary of processing process

1. After changing the bad hard disk, the system recognizes the primary, the original main disk is invalid, if the replacement of the old disk will be inserted into the system will cause confusion, resulting in the system, dial out is useless.

2.smart error does not prompt, this time is using the System test program (boot F10) that measured out the error.

3. Two hard drives of different sizes, one 146g, another 300g, can be done RAID 1 (mirror), Dell after the sale of some say no, I tested can,

4. If you dial off the array when you delete it, CTRL + C into the array management to delete the array, when the main disk if you dial out in advance, you can not delete the array, the main disk will be inserted again, the array will appear again, this time, the main disk dial out, from the disk did not dial, delete the array settings, ... Finally found that the data from the disk is still there.

this is supplemented by other netizens:

Suppose I group RAID 1.

1. One of the hard drives broke down. How can I determine which hard drive is having a problem?!

2. Determine the problem of the hard drive, how do I replace it? Directly off the machine and remove the problem hard drive and then replace the new?! Does the mirrored disk automatically resynchronize the data?!

3. Group RAID 1 can be multiple hard drives.

4. Group RAID 1. Whether 2 hard drives must be reformatted before they can be used.

5. The motherboard's own RAID chip security or array card is more secure.


Reply:

1: Can confirm according to the port number
2: Go straight to the new mountain.
3: Don't know
4: No, you can set a main disk directly, and then automatically mirror the second disk above
5: Not good to say

Brother RAID 1 O'Clock troubleshooting is as follows:
A. First of all, RAID1 need two of the same brand with the size of the hard disk, the failure of two types: data corruption and hardware damage caused (the hard disk itself has been damaged) if the former then hard to read the data, you can use! The latter words have two minutes to read and not to read!
B. The simplest way is to remove one of the first and then read another OK, such as OK is removed is the problem of the hard drive! The other is to test the other plate! is to use the exclusion method to find! If it is an array box, it will show the disc! Now Intel has a tool to show the current port's hard drive health, intuitive!!!
C, confirm the bad disk, the replacement of the same hard disk will be automatically restructured repair, the time spent and the capacity of the hard disk relationship, the larger the capacity of the longer!!


Question 2

xuefeng975 Netizen's question: Computer three hard disk, one is System disk, two 2T do is RAID 1 now array card off array, how to restore data?

york284 give the answer: it should be hard disk, and then a new disk to try, boot press shortcut key into the RAID management, there is a self-test, choose to set up a spare disk, built, you can rebulding; You can also enter the system, start the management program, let the program automatically rebulding, Recommend let system oneself rebulding. Operation is best to the array card instructions step-by-step operation, if the consequences of a mistake is very serious.
Sad reminders, occupy a position, also want to learn.
Connect separately, then use Diskgenius to search for partitions. Data important never rebuild the array.

Question 3

The RAID 1 data disk is broken, but can you just hang up with a new hard drive?

RAID1 broke a hard drive.
Will bad take out, replace on new, in Raid control, Add/remove SPARE (add idle Disk), after success, RAID status is rebuild, etc fixed OK

Question 4

A computer, with a RAID card to do the RAID1, now can not start, there is no way to read the data on the hard disk?

Well, just tried, sure enough! That is, do a good RAID1, in fact, 2 hard drives alone directly plugged into the computer, can be read?

Question 5

RAID1 a hard drive to work? Do not know how to do the raid volume, 1 block How to say is RAID?


Very simple first RAID1 principle is 2 pieces of hard disk synchronization data simple to say is mirroring each other, then if 1 hard disk is not working
RAID1 I break a plate and scrap the whole array, then I lose the meaning of RAID1.
So a disk can work, and I tried it on Intel's Raid chip.
