SMART activity instructs the controller to check certain SMART supported
thresholds by the disk vendor. An AEN is logged to the alarms page if a drive
reports a SMART failure.
The show selftest command displays the current selftest background task
schedule as illustrated below. Selftests do not have a time duration since they
are completed momentarily.

/c x 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 9750, 9690SA, and 9650SE RAID controllers, the Verify Task Schedule
can be either “basic” or “advanced.” (For details about the associated
comands, see “/cx set verify=advanced|basic|1..5” on page 72).
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 66.
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
