Data recovery how to recover data from 3disk RAID5, with disk0 and disk1 DEFUNCT on an IBM eServer xSeries 225 Model 8647-5BX

I'm going to go out on a limb and assume that you don't have a good backup of the data on your RAID array. So, generally speaking, the operating system is probably installed on a separate disk from your raid array (not a guarantee). But if this is so then you should be able to reinstall your operating system and drivers (esp RAID controller) to that (separate) disk and you're off to the races (replace this system disk if necessary). -OR- Depending on the make of your RAID controller you may be able to transplant your RAID controller into another machine and all the original drives along with it, so long as it has a battery backup and you place all the drives in their original order. If there is no battery backup on your RAID controller then DON'T PULL THE PLUG ON THE ORIGINAL MACHINE AND DON'T EVEN CONSIDER removing the RAID controller in any way. If you have any doubts, whatsoever, have someone with experience in RAID arrays do the work for you. It will be well worth it! (RAID arrays aren't for the faint of heart)...

The key is there only to lock the case. If its in the locked position and you have no key and you absolutely must open the case then go to your local locksmith and they can make one for 15-20$.... How to open the case depends on the model number...

Ok, you need to go into the BIOS and change the boot order of your server, as the power comes on press and hold F2 and then go into the boot menu and change the order of the boot to allow the USB to boot first.

I think first u disconnect ur all HDD to server. then u enable ur booting HDD or operating HDD...and setup again....

Another way: If u have original windows ..u can use windows recovery disk ...then recover ur missing file(kernel).

Thanks

The likelyhood that 2 drives fail at the same time is remote. I would first look to teh controller as the problem. Also, check the power supply. The only common things are the 5V and12V supply.

CHANGE RAM OR CLEAN RAM

I"t says one logical drive is offline and two physical drives are defunct."


sounds like RAID. Try booting up off of one drive. If there is no OS, try keeping one drive in the drive bay and see if you get a orange light then. like dereknewland said, could be the backplane.

Please take down time and blow air through a blower into the server when its completely powered off .
