Dell PowerVault MD 3000 showing degraded physical disk channel
Hello;
I have a Dell PowerVault MD3000, and it is showing a degraded physical disk channel error and individual physical disk - degraded path error.
The recovery guru suggests contacting a technical support representative to fix the error and do not try to fix it myself.
Any thoughts on how to proceed with fixing my issue? I am afraid to lose connection to my DAS and lose my data.
Below is the status of my physical disk channel:

I'd normally just replace the disk and the controller will reset the path to optimal automatically. You could upload the support bundle and we can look through it, Click the Support tab, then click Gather Support Information. storagearrayprofile and majoreventlog are the most useful of the files but the whole zip bundle helps. The recovery guru doesn't want you to reset the channel stats manually without first fixing the fault. There may be other problems lurking at the bottom of th recovery guru page, so many people don't scroll to the bottom.

"Enclosure 0, Slot 12" is not very well, you can open majoreventlog.txt and search for that string yourself, the file is humanly readable except for the raw text.
Enclosure 0, Slot 3 isn't that happy either.
There's also been some recent PSU events but that could have been someone playing about with the power cables.

So what I have to do to fix these slots? All Disks are optimal.
Is there a possibility to lose connection to my DAS?

If you havent already, Do a Full backup NOW!
To replace disk 12 you have to fail it via MDSM right click and select fail disk. Bear in mind that disk counts from zero, not one.
You can also log on Dell's forum and they will confirm this is correct disk to swap.

But the status of my physical disks are all optimal, and even if I try to replace one I got a message stating that no failed physical disk in that storage.

So i can keep it and when it fails i can change the disk without risking losing my data or connection to my storage.
