4.10.8 Regenerating Logical Drive Parity
(Applies to RAID Levels 1, 3, 5, and 6)
If no verifying method is applied to data writes, this function can often be
performed to verify parity blocks of a selected array. This function
compares and recalculates parity data to correct parity errors.
Figure 4 - 47: Confirm Box
Choose the logical drive that you want to regenerate the parity for, and
then press [ENTER]. Choose Regenerate Parity, then press [ENTER].
When prompted to “Regenerate Parity?,” select Yes.
Please refer to Chapter 11 Data Integrity for more information on parity
regeneration.
4.10.9 Media Scan
Media Scan examines drives and detects the presence of bad blocks. If any
data blocks have not been properly committed and are found during the
scanning process, data from those blocks are automatically recalculated,
retrieved and stored onto undamaged sectors. If bad blocks are encountered
on yet another drive during the rebuild process, the block LBA (Logical
Block Address) of those bad blocks will be shown. If rebuild is carried out
under this situation, rebuild will continue with the unaffected sectors,
salvaging the majority of the stored data.
