Chapter 2: Getting Started

With some models of hard drives, if the Master hard drive fails, it 
may cause the Slave hard drive to be unrecognized by the 
computer's operating system. Where a RAID 1 (Mirroring) array 
exists on the Master/Slave pair, this condition may cause the 
operating system to freeze. 
Do NOT create a RAID 1 (Mirroring) array with two Parallel ATA 
hard drives using the Master/Slave arrangement on Channel 3 
(the Parallel ATA port). 
You can create a RAID 1 (Mirroring) array by combining hard 
drives on: 
• 

Channels 1 and 2 (Serial ATA only) 

• 

Channels 1 and 3 (one Serial, one Parallel) 

• 

Channels 2 and 3 (one Serial, one Parallel) 

 

For automatic rebuilds of a mirrored array, attach a spare drive to the FastTrak 
S150 TX2plus. Drives that are not assigned to an array and are the same size or 
larger than the original will be used for the automatic rebuild. This is performed 
in the background under all supported operating systems, except DOS. At a 
later time, the system can be turned off and the failed drive can be physically 
removed. 

During startup, the disk arrays on the FastTrak S150 TX2plus are recognized in 
this order:  

1.  The array set to bootable in the FastBuild Setup.  

2.  The Array number (i.e. Array 0, Array 1…). This would be involved in 

determining which drive letters will be assigned to each disk array. 

All disk array data is saved into the reserved sector on each array member. 
Promise suggests that users record their disk array information for future 
reference. 

Another feature of the FastTrak S150 TX2plus disk array system is to recognize 
drive members even if drives are moved between different FastTrak S150 
TX2plus card connectors. Since each drive’s array data identifies itself to the 
array, it is possible to move or swap drives without modifying the array setup. 
This is valuable when adding drives, or during a rebuild.
