Creating a Hot Spare Drive for Mirrored Arrays
For automatic rebuilds of a mirrored array, attach a spare drive to the FastTrak
S150 TX4. 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 S150 TX4 Orders Arrays
During startup, the disk arrays on the FastTrak S150 TX4 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 S150 TX4 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 S150 TX4 disk array system is to recognize
drive members even if drives are moved between different FastTrak S150 TX4
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.
