/cx show verifyrate
/cx set verifymode=
/cx show verifymode
/cx set selftest=enable|disable
The /cx set self-test command enables or disables the specified controller's
SMART self test..
Example:
//localhost> /c0 selftest=enable
enables the selftest on controller c0.
/cx set spinup=nn
The /cx set spinup command allows you to set a controller-based Disk Spinup
Policy that specifies how many drives can spin up at one time. The value must
be a positive integer between 1 and the number of disks/ports supported on
the controller (4, 8, or 12). The default is 1.
This policy is used to stagger spinups of disks at boot time in order to spread
the power consumption on the power supply. For example, given a spinup
policy of two, the controller spins up two disks at a time, pause, and then spin
up another two disks. The amount of time to pause can be specified with the
Spinup Stagger Time Policy (/cx set stagger=nn).
Not all drives support staggered spinup. If you enable staggered spinup and
have drives that do not support it, the setting is ignored.
/cx set stagger=nn
The /cx set stagger command allows you to set a controller-based Disk
Spinup Stagger Time Policy that specifies the delay between spin-ups. The
value must be a positive integer between 0 s and 60 s, where s is seconds. This
policy, with Disk Spinup Policy, specifies how the controller spins up disks at
boot time. The default is 6 s.
/cx set autocarve=on|off
The /cx set autocarve command allows you to set the autocarve policy to on
or off. By default, autocarve is off.
When the autocarve policy is set to on, any unit larger than the carvesize is
created or migrated into one or more carvesize volumes and a remaining
