Case:Customers are stored in IBM DS3400 optical fiber, with a total of 10 hard disks. Each hard disk is RAID5 made of 450G. The server is Redhat Linux. A set of RAID5 is made.The partition format is EXT3, which stores about 3T DCOM Hospital -specific format files.Due to the loss of RAID information, the data…

Case:The operating system is: Winodws Server 2003 database: Oracle 10.0.2 SQL Server 2005 storage device is: IBM DS3200, 2, a total of 15 hard disks, each hard disk 1T capacity.One IBM DS3200 can only be connected to the hard disk and only connect to 12 hard disks, and the other IBM DS3200 is connected to…

Case:Unix operating system, the file system is JFS2, IBM AIX server, and LV on IBM AIX JFS2 is deleted by about 200,000 files by the upper script, which exists in different directory. Solution:After the engineer analyzes all the original LV DD to the recovery platform, the AIX JFS2 LV that is deleted by the independent…

Case:The IBM 3650 server, the bottom layer uses 5 SAS 500GB disk RAID5, one of which is a heat -reserve disk.The server operating system is Windows 2003 X64. The entire storage is divided into three partitions. The first 40GB is the Windows system area, the second is about 700GB, which is the partition where the…

Case:IBM 3650 server, use 5 SAS 300GB disks as RAID5; the entire storage only divides one LUN, divided into 3 partitions, the first partition is the partition of the Windows 2003 system, and the second partition is the partition of the SQL Server 2005 production library.The third partition is a backup partition. Solution:1. By separate…

Case:The total 8 hard disk groups of IBM 3650 have two groups of RAIDs. Both RAID1 is the first to turn on the light, No. 7.Run normally, look for IBM after sale, and the latter three disks are chaotic, causing 3 disks to light up. The problem is that the system can go in. The…

Case:IBM 3512 disk array storage, 5 SAS hard disks, a capacity of 2T.Raid5. Data suddenly cannot be accessed.RAID information is lost. Solution:Start detecting 5 hard disks and found no hardware problems.According to analysis, the RAID5,5 hard disk made by 4 hard disks is a heat disk.Analyze the original RAID5 parameter, and directly reorganize recovery.The data…

Case:The RAID0+1 composed of 8 146G SAS interface hard disks. Multiple disks are lost at the same time, so that the office system cannot run normally. Customers then contact our engineers and did not perform other operations. We immediately fixed disk. Solution:Our engineer first draws out the hard disk and mark it in order; detects…

Case:Customer data is lost due to improper operation. Solution:After that, the customer contacted the data recovery center, and after consulting, he took the laptop to the data recovery company.Through testing, the engineer found that the customer’s hard disk was encrypted. This is a bit complicated for this phase, but the engineers have many years of…
