Alphabetical list of commands
smart enabled|disabled|on|off|detect-only
Optional. Enables or disables SMART (Self-Monitoring Analysis and Reporting Technology)
monitoring for all disks in the storage system.
•
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. 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 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. Setting the delay to 0 will disable spin
down. The default is 15 minutes.
super-cap-failure enabled|disabled|on|off
Optional. Sets whether the cache policy will change from write-back to write-through when the
supercapacitor that provides backup power for cache is not fully charged or fails.
•
disabled
or
off
: The supercapacitor failure trigger is disabled.
•
enabled
or
on
: The supercapacitor failure trigger is enabled. This is the default.
sync-cache-mode immediate|flush
Optional. Sets how the
SCSI SYNCHRONIZE CACHE
command is handled.
•
immediate
: Good status is returned immediately and cache content is unchanged. This option
is the default.
•
flush
: Good status is returned only after all write-back data for the specified volume is flushed
to disk.
temperature-exceeded enabled|disabled|on|off
Optional. Sets whether the system will shut down a controller when its temperature exceeds the
critical operating range.
•
disabled
or
off
: The over-temperature trigger is disabled. This is the default.
•
enabled
or
on
: The over-temperature trigger is enabled.
utility-priority low|medium|high
Optional. Sets the priority at which data-redundancy utilities, such as vdisk verify and reconstruct,
run with respect to I/O operations competing for the system's processors. (This does not affect vdisk
background scrub, which always runs at “background” priority.)
•
high
: Utilities have higher priority than host I/O. Use when your highest priority is to return the
system to a fully fault-tolerant state. This can cause heavy I/O to be slower than normal. This is
the default.
•
medium
: Utility performance is balanced with host I/O performance.
•
low
: Utilities run at a slower rate with minimal effect on host I/O. Use when streaming data
without interruption, such as for a web server, is more important than data redundancy.
