Even though this product has reached its end of interactive support with us we always try to help as much as we can on some of the issues you may experience.
Recovering the operative system sometimes gets complicated. As far as we understand you are using the software mirroring from Windows 2008 R2 Server; since it seems that only works with basic instead of dynamic this points to an issue within the Operative System.
This could be just a setting that needs to be changed within Windows so it can take the dynamic mode. In this case we highly suggest having Microsoft support involved in this since we do not carry much information about how to troubleshoot Microsoft related issues.
Beard in mind that it is always recommended having the latest firmware revision on the server board; you can find the latest version here
Please do not hesitate in contacting us again if you need further assistance.
Do you mean the onboard RAID controller? If so, it will be required to format the drive once the volume has been created.
The article is right. You can create a RAID 1 without losing any data with the Intel Matrix, now called Intel(R) Rapid Storage Technology.
However, the RAID solution that we have on this server board is the Intel(R) Embedded Server RAID Technology 2 (ESRT2) which does not offer this option.
