/cx set verifyrate=<1..5>
This command sets the verify task rate of the specified controller. The verify
task rate sets the verify execution priority relative to I/O operations.
This task rate is of the range [1..5], where 5 denotes the setting of fastest
background task and slowest I/O, as follows:
5 = fastest verify; slowest I/O
4 = faster verify; slower I/O
3 = balanced between verify and I/O
2 = faster I/O; slower verify
1 = fastest I/O; slowest verify
This command applies to the 7000, 8000, and 9000 models controllers.
Example:
//localhost> /c1 set verifyrate=2
Setting Verify background task rate on /c1 to [2] (faster I/O) ... Done.

/cx show verifyrate

/cx show verifymode
/c x set selftest=enable|disable
[task=UDMA|SMART]
This command enables or disables all selftest tasks or a particular
selftest_task (UDMA or SMART).
The selftest schedule is always enabled.
For 3ware RAID controllers older than the 9690SA, two self-tests can be set:
one to check whether UDMA Mode can be upgraded (applies to PATA drives
only), and another to check whether SMART thresholds have been exceeded.
For 9750 and 9690SA controllers, you can only check the SMART thresholds
for drives. 7000/8000 series have the same internal schedule, but it is not
viewable or changeable.
Example:
//localhost> /c0 selftest=enable task=UDMA
enables UDMA selftest on controller c0.
