Promise FastTrak 579 Parallel ATA / Serial ATA RAID Introduction

Rebuild an Array
To Rebuild is to restore redundancy to a RAID 1 or 0+1 after one of its drives has
failed. Unlike Synchronization, a Rebuild is a repair operation.
When a drive fails for any reason, the Array goes Critical. An Array Critical
icon displays in Tree View.
To obtain the desired result, you must make these settings before the rebuild
operation begins.
Automatic Rebuild
Normally, the rebuild process begins automatically when you replace the faulty
disk drive. The Controller recognizes the new drive and begins the process a few
moments later.
If your array has a Hot Spare drive, the rebuild begins without waiting for a
replacement drive.
Be sure to replace the faulty drive as soon as possible.
If the popup messages are enabled, one will notify you when the rebuild is
successfully completed. The array will return to Functional status.
During the Rebuild process, the array will be available for use but it may run
noticeably slower. If the popup messages are enabled, one will notify you when the
Rebuild is successfully completed. The array will return to Functional status.
