120 Alphabetical list of commands
fan-failure enabled|disabled|on|off
Optional. Sets whether the cache policy automatically changes to write-through when a fan fails.
host-cache-control enabled|disabled|on|off
Optional. Sets whether the host can modify the cache setting. The default is disabled.
missing-lun-response notready|illegal
Optional. Sets the missing-LUN response which enables the host drivers to continue probing for LUNs
until they reach the LUN to which they have access.
• notready: Sends a reply that there is a LUN where a gap has been created but that it’s not
ready. Sense data returned is sensekey = 2, code = 4, qualifier = 3. This option is the default.
• illegal: Sends a reply that there is a LUN but that the request is illegal. Sense data returned is
sensekey = 5, code = 25h, qualifier = 0.
partner-firmware-upgrade enabled|disabled|on|off
Optional. Sets whether component firmware versions are monitored and will be automatically
upgraded on the partner controller.
partner-notify enabled|disabled|on|off
Optional. Sets whether to notify the partner controller that a trigger condition occurred. Enable this
option to have the partner also change to write-through mode for better data protection. Disable this
option to allow the partner continue using its current caching mode for better performance. The
default is disabled.
power-supply-failure enabled|disabled|on|off
Optional. Sets whether the cache policy automatically changes to write-through when a power
supply fails.
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. Each disk added after detect-only is set retains its
SMART setting. Enabled by default.
super-cap-failure enabled|disabled|on|off
Optional. Sets whether the cache policy automatically changes to write-through when cache backup
power is not fully charged or fails.
sync-cache-mode immediate|flush
Optional. Sets the option that controls 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 forces a controller shutdown if a temperature is detected that
exceeds system threshold limits.
utility-priority low|medium|high
Optional. Sets the priority at which jobs (such as vdisk verification and reconstruction but not
background scrub) run with respect to I/O operations competing for the system’s processors: low,
medium, or high.
spin-down
Optional. Enables or disables drive spin-down (DSD) for available disks and global spares. Disabled
by default.
spin-down-delay delay
Optional. Sets the period of inactivity after which available disks and global spares automatically
spin down, from 1–360 minutes. DSD is enabled by a value in this range, or is disabled by the value
0. If DSD is enabled and no delay value is set, the default is 15 minutes.
