problems after changing hard drive

hi forum

i have an problem with an hard drive in my server.

it is an ml350 g5 with an p400 controller.

there are two raids installed - on raid 1 an one raid5 with an spare disk

one of the disks in the raid5 (an GB0750C8047 with 750 gb) is broken so that the spare is used.

i bought now an 454146-B21BR with 1tb and replaced the drive.

now i get error messages:

cciss_vol_status /dev/cciss/c0d0

does it mean that the new drive isn't ok?

or is it my fault?

what can i do now?
