How to install

I have prolinat 800 server with 1-18GB H/D with NT running as PDC.
I wanted to install smart array 431 controller with 3-new 18GB H/D along with old H/D to make it as RAID5.

How to install array controller without loosing data?

If you are migrating from a standard scsi controller to an array controller you will have to back up all data, create your new array install your base so and restore from backup. Why you might ask. When an array controller is configured it writes a disc table to the add's whereas the standard scsi does not and likewise you cannot go from an array controller to a standard controller and not loose data.
