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.
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 m i nu t e s. T he de f au lt is 15 m in ut e s.
single-controller
Optional; for use by a service technician only. For a system that had two controller modules but
now has only one and is intended to be used as a single-controller system, this parameter changes
the operating/redundancy mode to Single Controller. This prevents the system from reporting the
absent partner controller as an error condition. This parameter does not affect any other system
settings. Installing a second, functional controller module will change the mode to Active-Active ULP.
You cannot enable this parameter if the independent-cache parameter is enabled.
auto-stall-recovery enabled|disabled|on|off
Optional. Detects situations where a controller stall is preventing I/O operations from completing,
and recovers the system so that at least one controller is operational, thus avoiding
data-unavailability situations. This feature focuses on Active-Active I/O stalls and failover/recovery
stalls.
When a stall is detected, event 531 is logged.
• disabled or off: Auto-stall recovery is disabled. The system will constantly perform auto-stall
detection in the background but will not automatically perform recovery actions. This is the
default.
• enabled or on: Auto-stall recovery is enabled. The system will constantly perform auto-stall
detection in the background and automatically perform recovery actions.
