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 minutes. The default is 15 minutes. single-controller Not supported. 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.
