UNSOLVED
replaced disk in MD3000 unassigned
I've got an MD3000/MD1000 data array with 3 disk groups. Two of those disk groups have a single hot spare. All drives are identical within a given disk group (i.e. 1,863.017 GB SAS). I had a reported disk failure and saw that the hot spare has filled in keeping the data both redundant and intact (RAID 5).
I purchased a similar replacement drive that is listed as compatible by DELL. However, when I place it into the array, it appears as an unassigned drive and does not initiate a rebuild as described by the Recovery Guru. The Recovery Guru also says there is no Service Action (removal) allowed.
Does anyone know how to initiate the rebuild of the RAID onto the replaced drive?
The Dell part# is 0F617N.
Seagate ST3300657SS, Firmware ES62
Yes, when I use MDSM to Modify/Add Free Capacity, the only disk group listed is the one with the failed drive - and the inserted drive is the only disk listed as an option in the Add Capacity drop-down selector.
Is this where I add it in? Why doesn't the Recovery Guru spell that out?
I couldn't add the disk as Free Capacity to the disk group but I was able to use Replace Physical Disks to initiate a Copyback on the newly installed drive. I'm waiting for it to complete but hopefully I'm on the right track.
I simply don't understand why this is a guessing game on how to implement. That's what the Recovery Guru should be explaining. Instead, it essentially says "You can't do anything. Contact Dell Support".

Hello sgwillia,
In most cases the copy back should start after the replacement drive has been inserted. I have seen some cases where it doesn’t, and in those cases doing the Replace Physical disk option resolves the issue. What is the firmware that is running on your MD3000? I have seen if you are running older firmware and replace a HDD with newer firmware can cause this issue as well.
Please let us know if you have any other questions.

Hello sgwillia,
What is the dell part# that is on the replacement drive? If you go in MDSM and go to the modify tab, then select add free space is the drive that you replaced present?
