By default, Data ONTAP performs a weekly RAID-level scrub starting on Sunday at 1:00 a.m. for a duration of six hours. You can change the start time and duration of the weekly scrub, add more automatic scrubs, or disable the automatic scrub.
To schedule an automatic RAID-level scrub, you use the raid.scrub.schedule option.
To change the duration of automatic RAID-level scrubbing without changing the start time, you use the
raid.scrub.duration option, specifying the number of minutes you want automatic RAID-level scrubs to run. If you set this option to
-1, all automatic RAID-level scrubs run to completion.
Note: If you specify a duration using the raid.scrub.schedule option, that value overrides the value you specify with this option.
To enable or disable automatic RAID-level scrubbing, you use the raid.scrub.enable option.
For more information about these options, see the na_options(1) man page.
