Basically, I think reconstructing is for RAID level migration and online capacity expansion (with drives already installed in original correct slots). It is very unfortunate for you. However, the drives must remain on the same channel and be reinstalled in the same order as in the original configuration if removed. I think if you are able to do so then you will definitely get the data.<br />

All the best.

Hello,<br />
<br />
Thanks for the suggestions. Is there any way to find out what the sequence was ? (serial numbers , ..) <br />

Thanks<br />

Dear<br />
<br />
One of the system engineers has removed the disks of a raid 5 set (7 disks) and not noted the disk sequence. When replacing the disks the OS is no longer booting.<br />
Is there a way of retrieving the data? <br />
<br />
Thanks<br />

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

RAID stands for Redundant Array of Independent Disks.

RAID is data storage technology that allows multiple drives to be used together as a single virtual drive for reasons such as fault tolerance, reliability and performance. 

There are several different levels of RAID that determine how the data is stored and the level of redundancy achieved across the drives.
