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.
spin-down-delay
delay
Optional. Sets the period of inactivity after which available disks and global spares will spin down.
The default is 15 minutes. Setting the delay to 1–360 minutes will enable spin down; setting the
delay to 0 will disable spin down.
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. (2012-01-21 11:59:37)
