set ondegrade=cacheoff|follow
This command is only for 9500S controllers.
This command allows you to set a controller-based write cache policy. If the
policy is set to cacheoff and a unit degrades, the firmware will disable the
write-cache on the degraded unit, regardless of what the unit-based write
cache policy is. If the policy is set to follow and a unit degrades, firmware will
follow whatever cache policy has been set for that unit. (For details about the
unit-based policy, see “/cx/ux set cache=on|off [quiet]” on page 61.)

set spinup=
nn
This command is only for 9000 series controllers.
This 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.
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 2, the controller will spin up two disks at a time, pause, and then spin
up another 2 disks. The amount of time to pause can be specified with the
Spinup Stagger Time Policy (/cx set stagger).

Not all drives support staggered spinup. If you enable staggered spinup and
have drives that do not support it, the setting will be ignored.

set stagger=
nn
This command is only for 9000 series controllers.
This 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 to 60 seconds. This policy, in conjunction with Disk Spinup
Policy, specifies how the controller should spin up disks at boot time. The
default is 6 seconds.

set autocarve=on|off
This command is only for 9000 series controllers.
This command allows you to set the auto-carve policy to on or off. By default,
autocarve is off.

When the auto-carve policy is set to on, any unit larger than the carvesize is
created or migrated into one or more carvesize volumes and a remaining
