Case:
The customer company server is suddenly powered off when it is used normally and cannot be started.Enter the RAID card configuration program and find that the array information is lost.
Solution:
Because the user cannot provide the type of array, we can only judge ourselves. Because there are only two disks, it is better to judge, either array 1 or array 0.After a simple analysis, it is found that it belongs to the array 0. When detecting the hard disk, it is found that there is a lot of bad sectors to deal with it: the image has a bad sector disk, and the image is analyzed after the mirror is completed.Since the user uses the Win2003 file system, the size of the block is very easy to analyze.After analysis, the block size is 128SEC, and the sequence is HDD1, HDD2.After reorganizing and checking the data with the user, the user’s DB2 database is intact and lossless.
