show verify
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 51.
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 and
RAID 6, 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.
