MD3200 Did not fail disk before replacement

So I took a chance and removed the replacement disk. I inserted the disk that had a predicted failure and it immediately reported physical disk failure which I am guessing put it into the failed state? So now I am back to square one. I removed the failed disk and inserted the spare described previously. I get no lights (power or activity) and the reported status is assigned and offline. Can someone assist me to understand what is going on here? The desired end state is that we have the spare disk working in place of the failed disk. Thanks in advance for your help.

Hello, It seems like you’re dealing with a tricky situation. Please try below steps:

• Reinsert the old disk: If the old disk is still functional, reinsert it. The system should recognize it and bring it back online.
• Fail the old disk: Once the old disk is online, you should manually fail it using MDSM. This is done by selecting the disk, right-clicking, and choosing Advanced -> Fail.
• Replace the disk: After the old disk has been failed, you can replace it with the new disk. The system should automatically rebuild the RAID using the new disk.

If the system doesn’t recognize the new disk or doesn’t start the rebuild process, there might be a problem with the new disk. Make sure the new disk is compatible with your MD3200 and is functioning correctly. It’s always recommended to have a backup of your data before performing these operations.

Hello @Dell-ErmanO​  - Thank you for the quick response. We attempted the steps you provided but when we inserted the original disk, it immediately went to failed status in MDSM. We checked to see if we could manually fail it and the option was greyed out. Any thoughts on how to proceed?

Mattymil,

Really in order to move forward we would need to check the logs to understand the exact issue occurring, as there can many reasons that it is causing the drive to not kick in and replace. So I would suggest you upload the support bundle, as described here, and I will private message you your Service Request #.
