/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, 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 68).
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.
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, the show verify command displays the current verify background task schedule as illustrated below.
 
//localhost> /c1 show verify
 Verify Schedule for Controller /c1
 ========================================================
 Slot    Day     Hour            Duration        Status
 --------------------------------------------------------
 1       Mon     2:00am           4 hr(s)        disabled
 2       -       -               -               disabled
 3       Tue     12:00am         24 hr(s)        disabled
 4       Wed     12:00am         24 hr(s)        disabled
 5       Thu     12:00am         24 hr(s)        disabled
 6       Fri     12:00am         24 hr(s)        disabled
 7       Sat     12:00am         24 hr(s)        disabled
A status of “disabled” indicates that the controller will not use the defined schedule timeslots and will start verifying 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.
Example 2: Basic Verify Schedule
For 9650SE and 9690SA controllers, if the “basic” Verify Task Schedule is selected, the show verify command displays a schedule as illustrated below:
 
//localhost> /c1 show verify
 /c1 basic verify weekly preferred start: Friday 12:00am
