Dell Powervault failed hard disk and replacement

I have a Dell 2850 (not under warranty) connected to a Powervault 220. It is RAID5. I had a disk failure on 0:3 and replaced the drive. Via OpenManage, once I made the switch, the drive still shows offline and will not allow me to bring it back online, nor will it give me the option to rebuild. The light on the failed disk was blinking amber, and when I made the switch with the new drive, the lights went to green.  I rescanned the controller, but it didnt have an effect.
Currently, I can see no data that was on the virtual disk.

is there a hot spare in the raid? if yes, then it's normal that you cannot do that, as it's assigned as spare drive

sounds like the backplane is dead or dying, try to restart managenmet service and see what the RAID status is after 30mins or so.

does the drive seem to spin up?

any lights at all on the drive or noises.

is the disk rebuilding for the moment? (disk activity on the raid)?

There are a total of 8 drives in the PowerVault. Including the drive that I just replaced, all disk lights are solid green. The new drive is spinning.

The disk does not show rebuilding in OpenManage.

In disk management, it shows the virtual drive and needing initialized.

that doesn't sound good, are you sure only 1 disk failed and you only replaced 1 disk in the raid 5 array?

try a partition recovery / disk recovery tool (pc inspector, recuva, ...) to check if there is some data on the volume

Yes, only 1 disk failed out of the 8 in the raid 5.

Would a reboot of the server do any good?

Would disk recovery tool work since the drive/volume in disk management shows that the drive needs to be initialized?

Forgot to mention, under "my computer", i can still see the drive, and the total/free space. But when I open the drive, nothing is there.

how much is total and how much is free? try the data recovery anyway to check if it lists anything (if it doesn't do a deep scan)

Have not rebooted yet. We sent out an email that we will be rebooting at 10:30. Once the server is back up, I will see what happens and follw up.

Got it fixed. Booted to BIOS and forced drive online long enough to backup the data. I also found out that the drive was spanned and not RAID, which I am taking care of at the moment. Thanks agian for all of the assistance.
