Creating new mirror
I added the drive and set the SCSI ID. It shows up in Array Manager. I go to ServerName>Arrays>PERC Subsystem 1>PERC3 Controller>Channel 0, and I can see the drives. There are 2 drives for an existing mirror set. Also, the drive that wasn't mirrored, and the new drive that will be used to mirror that drive, for a total of 4 drives. The existing non-mirrored drive is 69 gb. The new drive is 137 gb.
How do I mirror this? I right-click on the 69gb drive, and there is no option to "Add Mirror". What am I missing?
Thanks

johnb352,
In array manager, you will be creating a new array group with Raid 1 with those new disks, it will not mention mirroring.
You will also lose the extra space on the new drive as it will only mirror the 69Gb.

For the life of me I don't see where I'd do that.
Don't see it when I right-click on a drive. When I run the Quick Access Window the closest thing I see that might work is Create Virtual Disk. And the only gives me the option for RAID-0.
Yup, I'm aware that I'd lose that space beyond 69Gb.
Where do I create the new array group?

johnb352,
Do you see the two array disks in array manager when you go to create the new virtual disk?
Are you using the Create Virtual Disk Wizard icon ?

First, thank you for helping with this.
Yes, I used the Create Virtual Disk Wizard icon.
This is the first screen that I get. The disk on the right is the new drive. But, the drop-down window only contains RAID-0

johnb352,
Array manager does not see the 2 disks that you need to setup the raid 1.
Check that the other spare disk is not setup as a hot spare.
You chould see two disks available 0:3 which is your new one and the existing 69Gb which I am assuming is 0:2.
Until you see two disks available in array manager, you will only have Raid 0 as an option.

It sees it. And I don't see how it could be a hot spare. Here's a screen shot.
0 and 1 are mirrored drives for the system partition.
15 is the existing 69 gb drive, that's used for data. And of course 3 is the new drive.
Is it possible that this PERC controller won't do 2 RAID-1 arrays?

ok, thats vital information.
You are reconstructing your existing Raid 0 on disk 0:15 into a Raid 1 with the new disk.
You should be able to "Add Member" to the Raid 0 disk array, which you would then add 0:3

Add Member!! That was it.
I don't understand the Raid 0 part. That's striping. I thought striping involved more than one drive. Drives 0:0 and 0:1 were already in a RAID-1. Which only left 0:15. How could 0:15 be striped with another drive? There was no other drive. But you're right, it shows exactly that in the Event log:
PERC 3/SC Controller 0, Virtual Disk (Virtual Disk 1) reconfiguration from RAID-0, 68.37GB, 64KB stripe size to RAID-1, 68.37GB, 64KB stripe size started.
Thanks for your help! I'm glad that's behind me ;-)
