Chapter 3: Using FastBuild Configuration
Utility
The FastBuild Configuration Utility offers several menu choices to create and
manage the drive array on the Promise FastTrak S150 TX4 RAID Controller
card. For purposes of this manual, it is assumed you have already created an
array in the previous chapter and now wish to make a change to the array or
view other options.
Viewing FastTrak S150 TX4 BIOS Screen
When you boot your system with the FastTrak S150 TX4 card and drives
installed, the Promise onboard BIOS will detect the drives attached and show
the following screen.

If an array exists already, the BIOS will display the above screen showing the
card’s BIOS version and status of the array.
The array status consists of five possible conditions: Functional, Synchronizing,
Rebuilding, Critical, and Offline.
Functional – The array is operational.
Synchronizing – The process of verifying data integrity by recalculating
redundant data and matching the data on the disk drives
Rebuilding – The process of reconstructing an array in Critical mode by placing
redundant data on a replacement disk drive.
Critical – Degraded array condition due to a failed or removed disk drive.
Applies to mirrored arrays (RAID 1 and 0+1) only. Fault tolerance is lost but the
data is still accessible. Triggers automatic rebuilding.
Offline – Striped arrays (RAID 0): Degraded array condition due to one failed or
removed disk drive. The data is not accessible.
Mirrored arrays (RAID 1 and 0+1): Degraded array condition due to two failed or
removed disk drives. Fault tolerance is lost. The data is not accessible.
