CLI Guide

• 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 dns-managment-hostname
Description
Sets a domain host name for each controller module to identify it for management purposes.
The controller will advertise the management host name to DNS servers. The DNS servers will in turn create
and advertise a fully qualified domain name (FQDN) for the controller by appending the management host
name to the DNS domain string that identifies the controller.
