4.4.6.1 Initialization
This option initializes the selected logical drive by writing zeroes to the
entire volume (if fast initialization is selected, zeroes are written to the
first sector only).
Note: After you define a logical drive, WebBIOS asks you for
initialization of the logical drive. LSI does not recommended
choosing to initialize, as a background initialization may run.
4.4.6.2 Check Consistency
This option verifies that the redundancy data is correct and available for
arrays using RAID 1, 5, 10, or 50. If a difference in the data is found, the
MegaRAID adapter assumes that the data is accurate and automatically
corrects the parity value.
