7.3 Regenerating Logical Drive Parity
Figure 7 - 15: Regenerate Logical Drive Parity
Parity regeneration is a function manually performed onto RAID-
1/3/5/6 arrays to determine whether inconsistency has occurred
with data parity.
You may perform the parity check directly without changing the
two options below, or set preferred options and then press [ENTER]
on “Execute Regenerate Logical Drive Parity” to begin the operation.
7.3. 1 Overwrite Inconsistent Parity
Default is “enabled.”
If an array’s data parity is seriously damaged, restoring parity data
by regenerating and overwriting the original data may cause data
loss. Disable this option if you suspect parity data has been
seriously corrupted.
7.3. 2 Generate Check Parity Error Event
Default is “enabled.”
When enabled, parity inconsistency will be reported as system
events.
IMPORTANT!
If a regenerating process is stopped by a drive failure, the process
cannot be restarted until the logical drive is successfully rebuilt by
having its failed member replaced.
