FastTrak TX4000 User Manual
Creating a Hot Spare Drive for Mirrored Arrays
For automatic rebuilds of a mirrored array, attach a spare drive to the FastTrak TX4000. 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.
How FastTrak TX4000 Orders Arrays
During startup, the disk arrays on the FastTrak TX4000 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.
How FastTrak TX4000 Saves Array Information
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 TX4000 disk array system is to recognize drive members even if drives are moved between different FastTrak TX4000 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.
