Dell T320 Server with PERC S110 Raid 1- has a degraded RAID 1 Array. no Read ahead / write through.

Event logs: Found this error - physical Disk 0;0;0;1 controller 0@connector 0 has failed.

When I use <control> C at boot to enter the raid setup, it states both drives are on line.

question: how do I remove the bad drive and rebuild the array......

select blink to 'blink' the faulty drive.

Does the server have hot swap bays? If yes, then there will be a red light on the drive caddy indicating the faulty drive.

If the drives are fixed, then the box will need to be powered down.

Check the board schematic in the product manual for SATA0 (Port 0) as that's the cable that is attached to the failed drive.

Swap the bad drive out with a good one. Boot. The software RAID should kick off a rebuild process without having to log in to the RAID BIOS.

As always, back up first!

I'm not sure how my response disappeared or did not submit.......David: How does the "blink" work and what does it mean?  

I will be at the customer site in the next 2 business days as their drive has arrived. I will follow up after I check the drives.....

If the drive is in a carrier the 'blink' causes that drive to blink

The server is not hotswap (we did not set this server up originally)  So the blink command seemed of no use.  All I have to go off is the : Event log: Found this error - physical Disk 0;0;0;1 controller 0@connector 0 has failed.

We are installing a backup system and then will pull drive "0" on the "o" connector.  

Q:   When I pull the "assummed" bad drive. Can I just swap and reboot or do I have to reboot with one drive first, then shut down and install the new drive  and boot for rebuild?

Thank you.

Well things went poorly, I shutdown the server removed drive 0, installed the new drive. States no bootable drive.  Dell's Perc S110 manual is so poor.  

I disconnected the connector 0 drive and expected the remaining Raid 1 drive (on connector 1) to boot.  There is a connector 0 and connector 1.  Again this is not a hot swap cage. It simply has two hard drives installed.

Can I put the other drive back and see if it boots?  

Should this be booting bios or UEFI?

Thank you I have to get this up tomorrow.

Sure. A RAID 1 mirror is basically two basic disks. It can be plugged in and it should boot with or without the RAID set up.

ok...I have the event log failure message on here. It indicates Controller one connector one as the bad drive...it should have booted when I removed that drive. It did not. It states there is no bootable drive.

I'm trying to 1. figure out why. the server is down.  2. how to quickly get it back up. If I re install the original drive and re scan will the array still be intact with the original drives and boot???

Does anyone have an idea as to why it did not boot. I simply wanted to rebuild the array with the new drive.
 Has anyone here had to replace a failed drive on a dell Perc S110 that was not hot swap drives.  Like others I can't believe Dell made just a lousy Raid controller program.

It's not Dell it is the chipset/software RAID setup.

Slave the drives up to another machine to see which one is good.

Plug the good one into port 0 on the server and try to boot.

If that does not work, then in the BIOS flip the RAID setup to AHCI and try to boot that way.

Worse goes to worst, image the good drive and restore the image as a Hyper-V virtual machine on a server or desktop to at least get them productive again. We use StorageCraft ShadowProtect's IT Edition for this task.

Dell offered a reasonable price on their extended warranty so we paid and a tech lead us thru the proceedure for replacing the drive. He actually wiped out a server in their lab to do so.

Okay, please share the procedure.
