9000 series controllers support background tasks and allow you to schedule a
regular time when they occur.
Verify is one of the supported background tasks. Rebuild and selftest are other
background tasks for which there are separate schedules. Migrate and
initialize are additional background tasks that follow the same schedule as
rebuild. For each background task, up to 7 time periods can be registered,
known as slots 1 through 7. Each task schedule can be managed by a set of
commands including add, del, show and set a task. Background task
schedules have a slot id, start-day-time, duration, and status attributes.
For details about setting up a schedule for background verify tasks, see
“Setting Up a Verify Schedule” on page 46.
Verify activity verifies all units based on their unit type. Verifying RAID-1
involves checking that both drives contain the exact data. On RAID-5, the
parity information is used to verify data integrity. RAID-10 and 50 are
composite types and follow their respective array types. On 9000 series, non-
redundant units such as RAID-0, JBOD, single, and spare, are also verified
(by reading and reporting un-readable sectors). If any parity mismatches are
found, the array will be automatically background initialized. (For
information about the initialization process, see the user guide that came with
your 3ware RAID controller.)
The
show verify command displays the current verify background task
schedule as illustrated below.

A status of “disabled” indicates that the controller will not use the defined
schedule timeslots and will start verifying immediately (within 10 to 15
minutes), if the verify command is entered manually, or it will begin
automatically if the autoverify option is set. Rebuilds, migrations, and
initializations will take priority over verifies.
