SOURCE: raid w/ hard drive defunct

Well lets make some assumptions
1. You have a Raid 5 System
2. You only have 3 drives in the Raid ARRAY
3. Only 1 drive has failed

To fix the problem you should only need to Replace the Failed Drive
Then start the raid management software or bios
Rebuild the array

If you have more than 1 drive failed in a RAID 5, and still must recover the data it is possible. But very expensive. Still fixable however.

SOURCE: Cant create additional raid

Hi martyblue
Check this for specs:
http://www.redbooks.ibm.com/xref/usxref.pdf

The raid controller onboard is dual channel. Are you using a serveraid card as well? How have you configured the existing arrays? You may need to use the other channel if not already in use. Are the new drives ultra320 drives of same speed?

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.

When i install MS windows server 2003 in IBM x3400 server it gives me message that setup could not find any hard desk installed in your computer. guys please help me temor


Ensure drives are seated correctly and set up the RAID config.

Then on the Blue screen of Windows installation it will say "press f3 for 3rd party drivers", hit F3 (I think its F3), then insert a floppy disk with the drivers for you RAID controller, setup will then say it has found the followign drivers "your device xxx" then it should* pick up the hard drives later on in setup.

:) - RAID controller drivers can be got from the manufacturer websites.... normally.

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...


Raid level 5 gives you some redundancy in your raid however it only allows you to lose one hard drive, two hdd lost would not permit to recover from. the parity bit can rebuild one hard drive but not two, sorry your raid might be lost
