Shalom,

Its important to say which type of raid you are using.

That system has a P400 card and can use hardware raid. If so, fixing this merely means replacing a hot swap disk.

If indeed as I suspect you used software raid, you have some fun with the when disks go bad document that we all love so much.

IMHO some steps are missing or different in the reply from Avinash V Rao, so I would suggest to follow the link in the first post.
