Degraded Disk Array Warning Message 2 Press a key to continue. 3 If your degraded unit has a drive indicated as Not in Use, the drive may still be usable. Try rebuilding with the Not in Use drive intact. Simply select the unit (highlight it and press Enter) and then select the Rebuild Unit button. 4 When the Rebuild confirmation screen appears, confirm that you selected the correct unit by selecting OK. 5 Press F8 to save your changes and exit 3BM. The unit will begin rebuilding after the operating system finishes loading. If the rebuild fails and you have no available drives, do one of the following: • If your system has hot-swap carriers, you can replace the failed or Not In Use drive and rescan (Alt-R) the unit. • If your system does not have hot-swap carriers, power down the system and replace the failed or Not In Use drive. Then power on the system and restart 3BM. Then follow these steps: 1 At the main 3BM screen, highlight an available drive to replace the faulted drive and press Enter to select it (see Figure 73). An asterisk appears in the left most column to indicate the drive is selected. 192 3ware Serial ATA RAID Controller User Guide
