      If the VDD Repair fails (the data is unable to be reconstituted due to a bad read on another drive (in a RAID5), or a degraded RAID group (not enough redundancy), then the affected LBA in the RAID Vol...If the VDD Repair fails (the data is unable to be reconstituted due to a bad read on another drive (in a RAID5), or a degraded RAID group (not enough redundancy), then the affected LBA in the RAID Volume is marked as an 'Unreadable Sector' (ends up in the USM log), and an error is returned to the host. In the background, the Write Verify to the 'bad' sector of the drive will result in the drive firmware reallocating the physical sector (transparently to the E-Series controllers).
