Issue

• disk in isw dmraid setup was failed, replaced, but didn't rebuild correctly
• dmraid mirror rebuild not accepting new disk
• dmraid mirror rebuild failed to update status
• The disk in isw dmraid setup failed, rebuild failed
• disk replaced and rebuild done via the Intel Matrix Storage Manager option ROM bios utility at power on/boot time.
• after booting up the system, dmraid -s (status) is still status : nosync
