In my IBM X226 server 2 HDD became unavailable in RAID 5 configuration. now I have replaced the hard disks and rebuild process is continuing. 1962 operating system not found error message is being shown while booting.

6 x 300GB (largest available U320 SCSI HDD Capacity) = 1800 GB

When you restored to factory setting you have reset the RAID configuration & probably lost all the data

you can use a HDD cloning software for that particular problem.

Hi

You would need 4 Hard disk drives in total. you would need to create 2 RAID 0 (striping) and then Mirror them (RAID 1). to elaborate, HDD A&B will be at RAID 0 as well as HDD C&D. after, you would have to Mirror your two RAID 0. (raid 0+1 is also known as raid 5)

Hope this helps.

When your system boots up you should see an option to access your raid controller if not or if your system doesn't see the controller at all you will have to download the utility software from IBM, but you need to be careful any change you make in the configuration of the disks will delete all data on your drives. This is non-recoverable loss. The utility has help and is fairly easy to understand.

just bad luck

YOU WILL NEED TO UPGRADE THE FIRMWARE ON THE OLDER DRIVES

Raid 6 will tolerate two simulatneous hard disk failures. So the posibility for data loss is very less. But the rebuilting steps defers for different server products like IBM and DELL. But normaly when u change a new hard disk the server will automatically starts the rebuilding process.

You don't say whether or not your os is on the RAID 5 partition. Assuming that it is (for performance reasons, this is not recommended) then you should check to see if you have the option of configuring a separate raid configuration on your raid card (e.g. do you have a card with more then one RAID channel?) If this is so, I would create a separate RAID 1 array and install the OS just on that. Then you can mount the RAID 5 array with your data intact. Once you're up and running, you can remove the old OS partition, as it's no longer needed.

to recover your data is very easy. just slave your hdd to a system that is working fine and switch it on.after windows has succesfully loaded go to my computer you will see to hard drive.the slave hdd will be labelled B.double click on it go to my documents and copy all your filesand save it on your working hard drive.after copying make sure you remove the slave hard disk
