/cx 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.
