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. • 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. To set spin-down parameters for a vdisk, use set vdisk. NOTE: Drive spin down affects disk operations as follows: • Spun-down disks are not polled for SMART events. • Operations requiring access to disks may be delayed while the disks are spinning back up. 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 available disks and 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. • enabled or on: Drive spin down for available disks and global spares is enabled. If the spin-down-delay parameter either is not specified or is specified with the value 0, the spin-down delay will be set to 15 minutes. spin-down-delay delay Optional. Sets the period of inactivity after which available disks and global spares will spin down. Setting the delay to 1-360 minutes will enable spin down; specifying the value 0 will set the delay to 15 minutes. The default is 15 minutes. Example 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 Success: Command completed successfully.
