PowerEdge T110 II PERC S100 and Openmanage - Changing Raid Config

I have a Dell PowerEdge T110 II with PERC S100: Driver Version  1.0.1-0021 I have 4 drives in a RAID 5 array and would like to change that to a 2 drive Raid 1 array. I loaded Open Manage on the system and I see that in the RAID section I can execute "Unassign  Global Hot Spare" on Drive 0 and 1. Is changing the Array to a RAID 1 mirrored 2 drive set as simple as unassigning drive 0 and 1?

If you have 4 drives and two are showing as hot-spares, then you don't have a RAID 5.

Should I upgrade that Driver to 2.0.0-0162 prior to this process?

You should always keep your system firmware and drivers up to date.

I am doing this all so that I can add to 2TB disks to the system and run virtual machines on those new disks.

Might want to make sure your processor supports VT ... a few of the low-end options for this server didn't.

Not to be ungrateful but none of this answered my question.

It is in a RAID 5 array, I may have misunderstood the Open Manage interface in that it may be that two drives are available to unassign as a hot spare, but once you unassign one the other will no longer be a hot spare.

But the bigger question is how can I change the Array to A Raid 1 array?

Thank you much. That helps. I will just backup, create a RAID 1 array and do a fresh windows install.

Thanks again.
