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, and
show verify
shows you
the current verify schedule.
For 9650SE and 9690SA RAID controllers, the Verify Task Schedule can be
either “basic” or “advanced.” (For details about the associated comands, see
page 73).
The basic Verify Task Schedule sets a weekly day and time for verification to
occur, and is designed to be used with the auto-verification of units.
The advanced Verify Task Schedule provides more control, and is equivalent
to the Verify Task Schedule available for 9550SX and earlier 9000 RAID
controllers.
For the advanced Verify Task Schedule, up to 7 time periods can be registered,
known as slots 1 through 7. This task schedule can be managed by a set of
commands including
add
,
del
,
show
and
set
a task. The task schedule has a
slot id, start-day-time, duration, and status attributes. Rebuilds, migrations,
and initializations follow similar background task schedules.
For details about setting up a schedule for verify tasks, see “Setting Up a
Verify Schedule” on page 67.
Verify
activity verifies all units based on their unit type. Verifying RAID 1
involves checking that both drives contain the same 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, 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.)
Example 1
:
Advanced Verify Schedule
For 9550SX and earlier controllers, and when
verify=advanced
for 9650SE
and 9690SA controllers running 9.5.1 or later, the
show verify
command
displays the current verify background task schedule as illustrated below.
