Can I switch Intel ESRT2 RAID 1 to Intel Storage Matrix (RSTe) RAID 1 without rebuilding the disk volume?

Greetings,

I have an Intel S3420GPC Server Board using latest BIOS build (0052 - 5/16/2014).  The server is currently configured to use the Intel ESRT2 RAID for a pair of WD Black 1TB drives configured RAID 1.  ESRT2 version is 10.0225163i.  Matrix RAID version is 10.8.0.1303.

There have been no issues with ESRT2.  I'm changing the backup strategy to include a 3rd WD Black 1TB internal drive for Windows 2008 R2 bare metal recovery backups.  I have run into an apparent limitation where the BIOS doesn't recognize this 3rd drive, so it doesn't appear as a separate drive under Disk Management for me to assign as a dedicated drive.

I have a need to switch to the Intel Matrix RAID and preserve the current ESRT2 RAID 1 disk configuration without having to rebuild the server.  Can this be done?

I don't think so and, if it is booting using UEFI, it won't boot at all if you change the mode.  Have you tried CTRL-E during POST to set the 3rd drive?

Davis, thanks for the reply.  I'll give that a shot and see if that works.
