I have a customer that has a Intel server with a S5000PSLSATA system board. The Server has been running fine for some time (5 Years). The server has 6 750Gb Seagate drives. 2 of the drives are configured as Global Hot Spares. The rest of the drives (4) are configured as a Raid 5 array. Last week, the server locked up and had to be rebooted. The customer called me when the server would not come up. The 2 global spares had died. The server was trying to rebuild the raid array because another drive was also failing. I had to order two more drives so i returned the server to the office for repair. When I started the server back up and entered into the (LSI) Embedded Raid II utility Version A.60, I noticed that two of the good raid drives showed READY and two of the other drives showed ONLIN A00-00 and ONLIN A00-01. The virtual drive still shows the raid 5 array with a size of 2.14TB but the status is degraded. Is there a way to add the two ready drives back to the existing array and let it rebuild without losing data?

Thanks for all your help.

If i read you correctly, you're not too clear on this, the 2 ready drives are the one you just installed so all you need to do is go into the lsi raid utility and mark the drives as hot spares. Once the rebuild is done you can remove the degraded drive and swap it with a good one, mark it as a hotspare, and be back at having 2 hot spares.
Lsi raid utility, raid properties, view existing array, manage array, manage hot spares

They got super lucky surviving a 3 drive loss. If they don't have a backup solution in place I recommend they get one going real quick. They still have three 5yr old drive in this...
