Checking data consistency
The Check Consistency feature verifies the correctness of the
redundancy data in the selected logical drive and allows the CU to
automatically correct any differences found in the data.
This feature can be used only on a RAID 1 logical drive, to verify the
data consistency between the mirrored physical drives. When a data
inconsistency is found, the CU can either report and fix the
inconsistency or report the inconsisteny only, depending upon the
parameter selected in the Adapter settings.
To start a consistency check:
1 In the Management menu, select Check Consistency , then press
Enter .
2 Use the space bar to select a logical drive.
Note: A consistency check can only be perfomed in logical drives
that supports RAID level 1. If you select a RAID 0 logical drive, a
check consistency cannot be performed message appears. To de-
select a logical drive, press the space bar again.
3 Press F10 .
4 Select Yes to start consistency check, then press Enter .
5 After the consistency check is completed, press Esc to return to the
previous menu.
When you press Esc while the check consistency is in progress, the
following options appear:
• Stop — The CU stores the percentage of the check consistency
already completed. When you restart the check consistency, it
continues from the last percentage completed rather than
from zero percent.
• Continue — Check consistency continues normally.
• Abort — The check consistency is completely aborted. If you
restart check consistency, it begins at zero percent.
