SSA Scripting 68IRPEnableThis option is not supported.LicenseKey, DeleteLicenseKeyThese options are not supported.MNPDelayThis option is not supported.NoBatteryWriteCacheWith this option, the controller can enable write cache when no battery is present or when the battery fails.Values are Enable or Disable. The default is Disable.Some controllers do not support this option.ParallellSurfaceScanCountThe ParallelSurfaceScanCount command specifies the number of parallel surface scans which can be activeat any time. The minimum and maximum values are controller and firmware release dependent. This featureis not supported by all controllers.N - number of scansPower modesIMPORTANT: A reboot may be required after switching power modes in order to optimize savingsand performance.IMPORTANT: When the power mode is set to Balanced, future controller configuration changesmay require a reboot for optimal performance.This option modifies the controller power mode. A value of minpower sets static settings to the lowest possible value and dynamically reduces powerbased on the workload. A value of balanced sets statistic settings based on the configuration and dynamically reduces powerbased on the workload (recommended). A value of maxperformance sets static settings to the highest possible value and does not dynamicallyreduce power (default).Example: PowerMode= [ MinPower | Balanced | MaxPerformance ]QueueDepthThis option is not supported.RapidParityInitializationThis option enables Rapid Parity Initialization. The RPI command is not supported on all controllers and isdependent on firmware and hard disk support. Command options are Enable or Disable.ReadCache, WriteCacheEnter a number between 0 and 100 to specify the percentage of cache that is to be allocated to drive readsor writes.
