Raid 1 failing hard disk
I have a Poweredge T420 that has 2 virtual disks setup, a raid 1 for the os and a raid 5 for data.
Disk 0:1:0 has predicted failure showing. Do I need to take the failing disk offline before I hot swap it?

Yes... as long as the Disk is "alive" you should set the drive "offline" because the HBA than is prepared that you will remove the drive in a hotswap manner.
If the replacement drive doesnt kick into the RAID1 you need to configure this new drive as a (global)"hot spare" and assign it to the existing disk group. Than the volume rebuild should start.
Regard,
Joerg

@Origin3k Thanks for the quick response. I have a similar dell server here in the office that I am going to test on before I try it on the clients server.

So far setting the bad drive to offline and then replacing seems to be working as it is rebuilding now on my test server.

Everything was looking good but now my Virtual Drive is showing a red X, any thoughts what I need to run?

I started going through the options and "Clear Virtual Disk Bad Blocks" cleared it up.

Hello, I'm afraid your disk will fail again soon.
Can you check the physical disk status? This needs a replacement, so it is best to get in touch with the local support.

@DELL-Young E This is just a test server I have setup in my office before I attempt it on the clients in production machine so I'm not overly worried if the disk are bad on it but I will look at what you sent.

I just realized on my test system I had 2 drives that were not Dell certified which I believe was causing a Non Critical error. Is this a major concern?

Hello, any problems occuring from not using a Dell certified part component can cause an issue, and we won't be able to assist, please note.

The drive swap on the clients server with a Dell certified drive went great. Thanks to all for your quick responses.
