verify task during the scheduled time windows. (For information about
schedules, see “Scheduling Background Tasks” on page 161.)
If Auto Verify is not set, you must manually specify when you want to run a
verify, on the 3DM
Controller Settings
page. If a schedule is set for verify,
then the verify that you manually start will only run during the scheduled
time.
You can set the Auto Verify policy while creating a unit through 3DM or you
can change the setting later using the following method.
To set the Auto Verify policy for an existing unit
1
Choose
Management > Controller Settings
from the menu bar in 3DM.
2
In the
Unit Policies
section of the Controller Settings page, check the
Auto Verify
box for the appropriate unit. (To disable this policy, uncheck
the box.)
The page refreshes, and a message at the top confirms the change you
have made.
Setting Continue on Source Error During Rebuild
The
Continue on Source Error During Rebuild
policy is available for units
which are redundant. (For units which are not redundant, this option is not
shown on the screen.) When this policy is set, ECC (Error Correcting Code)
errors are ignored when they are encountered during a rebuild. (ECC errors
are typically defects that have been detected in the drive since initialization.)
When this policy is not set, if a unit is rebuilding, the rebuild will abort when
it encounters an ECC error and the unit will be set back to Degraded.
Since enabling this policy could result in the loss of some source data in the
event of source errors, the default is to not enable this policy. Select this
option only if you want to ensure that a rebuild will complete successfully
without manual intervention. If the rebuild fails and
Continue on Source
Error During Rebuild
is not selected, then you have the option to start
another rebuild manually. After completing a rebuild with this policy enabled,
it is recommended that you execute a file system check when the rebuild
completes. Under Windows, you can do this by right-clicking on the Drive
and choosing Properties; then on the Tools tab, click Check Now.
To set the Continue on Source Error During Rebuild policy in 3DM

Management > Controller Settings
from the menu bar in 3DM.
