Drive Failure and Rebuild
Hi everyone, I have a dell powerdege 2950 I have 2 73GB drives that are in a RAID1 config. One of the drives shows degraded. we got the hard drive with the degraded status swapped out with a new drive. The status or state said it was forgein. We got that to go away and the disk appears to be online now but it has not rebuilt itself. not sure how to proceed. I thought it would automatically rebuild as a feature of the server. any help you could lend would be appreciated. on the Dell open manage server administrator console it does say firmware and driver versions are out of date. not sure if this is impacting the disk being rebuild. I wouldn't think so but thought I would add that in. Ray

You are likely getting that due to the Raid 5 being of different (larger or faster) size compared to the Raid 1. So the drive matches the drives in that Raid 1 but not the other. As you are assigning as a GLOBAL Hotspare it is just telling you that it won't be able to rebuild to the Raid 5 if there is an issue.

Could you attach a screen shot of the Physical Disks in OMSA?
Also whats the version of OS on the server?

AIIT76,
If the drive is showing as ONLINE under the Virtual Disk then it has already rebuilt to the array, or was configured as a separate disk. If the drive was waiting to be rebuilt it would be in a READY state. If you access OMSA, what are you seeing for the versions of driver and firmware for the controller? If they get far out of date then it can cause the array to show as Degraded, with no actual members missing or failed. Could you confirm this? Updating the controller will change it back to Optimal, if this is the case.
What is the OS on the server, as well as the versions you are currently at, and I can get you the proper updates.
Let me know.

When you click on reply, in the header you will see 2 icons, one with a piece of film with a + on it and the other which is a TV with a + on it. Hit the Film button with the + on it. That will allow you to insert the image in the post.

here are a couple of more shots. I don't think the drive has rebuild itself. all of the other drives say 300gb of 300gb used, available space 0, but in this picture you can see the one 73gb drive has all of it's free space so I am assuming it did not get rebuild and mirrored or maybe I am understanding this incorrect.

Could you run a dset report for me? I am going to send you an email with the link needed, could you reply with the report so I can review what occurred?

After reviewing the controller log, I was misunderstanding th situation you were in. What you will need to do is go to OMSA or the controller BIOS and assign the READY drive as a Global Hotspare. It will rebuild then in. Sorry for the misunderstanding.

yes the new drive was already loaded in place of the failed drive. it said it was ready but not online. once I assigned it as a global spare I saw the status change to rebuilding. All physical disks show to be online now so I think we are good.
I appreciated all the help and knowledge.

Remove the failed drive. After you assign that then it should automatically start rebuilding in place of the failed removed drive.
