10.3 Regenerating Logical Drive Parity
Fig. 10.15 Regenerate Logical Drive Parity
Parity regeneration is a function manually performed onto RAID-1/3/5 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 pre-
ferred options and then press [ENTER] on “Execute Regenerate Logical Drive Parity” to begin
the operation.
10.3.1 Overwrite Inconsistent Parity
Default is “enabled.”
If an array’s data parity is seriously damaged, restoring parity data by regenerating and over-
writing the original data may cause data loss. Disable this option if you suspect parity data has
been seriously corrupted.
10.3.2 Generate Check Parity Error Event
Default is “enabled.”
When enabled, parity inconsistency will be reported as system events.

NOTICE!
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.
