set disk-parameters


Description	Sets parameters that affect disk operation. Two features controlled by these parameters are disk Self-Monitoring Analysis and Reporting Technology (SMART) and drive spin down. Disks equipped with SMART technology can alert the controller of impending disk failure. When SMART is enabled, the system checks for SMART events one minute after a restart and every five minutes thereafter. SMART events are recorded in the event log. Changes to the SMART setting take effect after a rescan or a controller restart. For spinning disks, the drive spin down feature monitors disk activity within system enclosures and spins down inactive disks, based on user-specified settings. This command sets spin-down parameters for available disks and global spares. Spin-down settings do not affect leftover disks. To set spin-down parameters for a linear disk group, use the set vdisk command.

Syntax	set disk-parameters [smart enabled\|disabled\|on\|off\|detect-only] [spin-down enabled\|disabled\|on\|off] [spin-down-delay `delay`]
Parameters	smart enabled\|disabled\|on\|off\|detect-only Optional. Sets whether SMART is enabled or disabled for disks: disabled or off: Disables SMART for all disks in the system and for all disks added to the system. enabled or on: Enables SMART for all disks in the system and for all disks added to the system. This is the default. detect-only: Detects but does not change the SMART setting of each disk in the system, and for each new disk added to the system. spin-down enabled\|disabled\|on\|off Optional. Sets whether spinning disks that are available or are global spares will spin down after a period of inactivity shown by the spin-down-delay parameter. disabled or off: Drive spin down for available disks and global spares is disabled. This is the default. Disabling spin down will set the spin-down delay to 0. enabled or on: Drive spin down for available disks and global spares is enabled. If the spin-down-delay parameter is not specified, the delay will be set to 60 minutes NOTE:Drive spin down is not applicable to ADAPT disk groups or virtual pools. spin-down-delay `delay` Optional. Sets the period of inactivity after which spinning disks that are available or are global spares will spin down. Setting the delay to 1–360 minutes will enable spin down. Setting the delay to 0 will disable spin down. The default is 15 minutes.
Examples	Enable SMART and drive spin down, and set the spin-down delay to 10 minutes. # set disk-parameters smart on spin-down on spin-down-delay 10
