will be scrubbed every day. The options are Enable and Disable.

Patrol Scrub Interval

This feature allows you to decide how many hours the system should wait be-

correctable error, the error is corrected and sent to the requestor (the original

source). Memory is updated as well. Select Enable to use Demand Scrubbing

for ECC memory correction. The options are Enable and Disable.
