I have a PE T320 with a PERC H310 controller.

We have a RAID 10 setup with 4 drives.  One has failed.  How would I replace based on this picture?  The pic is the back of the PE.

Do you know which of the 4 drives has failed?  If so, you can just shut the system down, replace the drive, and restart.  The controller should start the remirroring automatically, but you should check that with OpenManage.

I'm assuming that you don't have hot-swap drives.  If you do, it is much easier both to identify the drive and to replace it.  You can just pull the correct drive and install the new one.

Of course, be sure you have a good backup first!

those don't look like drive bays in your photo, they look like chassis blanks. If you have a 4-disk array, are the trays not on the front of the server?

Remove the front bezel and you'll see if you have hot-swap drives or not.

The pic shows the front bezel removed.
OK... my error.

You'll want to take the side cover off to gain access to the internal hard drives.

I'm hearing that if they are hot-swap that it is imperative that you swap while the machine is running... otherwise it is imperative that you don't.

I'm guessing that once I remove the side I'll be able to tell if they are hot-swap drives or not?

if they are inside the case, they are probably not hot-swap. hot swap drives are generally accessible from outside the chassis. but it doesn't hurn anything to take a look inside by taking of the side with the machine running. Do that ans snap a photo of the inside for us.
I have had success with swapping out a single hot-swap drive even with the machine off.  You want to make sure, though, that the system does start reconstructing the array with the new drive.

I am highly doubtful that internal drives would be hot-swappable, but nothing wrong with taking a photo and getting a more solid answer.

Those are non-hot swap drives.  Do you know which one has failed?

HDD 0... the top one.  Do you think that this is a simple shut down, replace drive and boot up?
It should be.  If not, you should be able to initiate the re-striping/mirroring in the OpenManage application.  Have you installed that?

There are some instances (sorry... I can't name the specific models at the moment) where the re-striping/mirroring must be initiated in the controller's BIOS.  If so, just designate it as a hot spare and it should handle the rest.

I received the new drive, shut down the machine, replaced the drive (def not hot-swap) and booted the machine back up.

All VMs still function.

It was set to a RAID 10 with 4 discs.  Two sets of two discs mirroring each other.

Opening the Openmanage admin I see a yellow triangle next to Storage.  Clicking Storage shows the pic below:

what appears under that "available tasks" drop-down for the iperc?

Does this help?

What happens if you select "Replace member disk"?
And what do you get for Available Tasks on Physical Disk 0:0.

Only available tasks for Disk 0:0 is Offline.

Trying "replace member disk" yields "Storage Management only displays disks that can be used as a replace member. There are currently no disks that are available, large enough, or of the correct type to be used as a replace member for this virtual disk."

My screen shots could be that I am using a non-Dell disc.  

I don't see, on this Openmanager dashboard, anything that states the health of the RAID 10.
It sounds as if it's not seeing the new drive.  I'd reboot and look at what the controller BIOS utility tells you.  I think you get to it with Ctrl-R; you'll see a message about it when you reboot.
