The allowable cache ratios depend on the controller model and whether it has battery-backed write cache.
RebuildPriority, ExpandPriority
These options establish the priority for rebuild and expand functions. Rebuild has four possible values: Low,
Medium, MediumHigh, and High. MediumHigh is only available when Rapid Parity Initialization is enabled.
Expand has only three possible values: Low, Medium, and High.
These options are not required.
SurfaceScanDelay
Enter a number between 0 and 30 to specify the duration of the surface scan delay in seconds. This option
is not required. If you do not specify a value for this option, the delay remains unchanged. A value of 0
disables the scan.
SurfaceScanDelayExtended
Enter a number between 0 and 300 to specify the duration of the surface scan delay in tenths of seconds. This
option is not required. If you do not specify a value for this option, the delay remains unchanged. A value of
0 disables the scan.
If this parameter and SurfaceScanDelay are both in the input file, this parameter takes precedence.
SurfaceScanMode
This parameter specifies the Surface Scan Mode with the following values:
•
Idle—The delay interval is set with the normal values from SurfaceScanDelay or
SurfaceScanDelayExtended.
•
High—The surface scan enters a mode guaranteed to make progress despite the level of controller I/O.
•
Disabled—No mode is selected.
Video performance options
To use this features on an HP Smart Array G6 or G7 controller, a registered SAAP ("
" on page
) license key is required.
To optimize the controller performance for video, set values for the following options as indicated:
DPOEnable = No
ElevatorSortEnable = Yes
IRPEnable = No
In addition, do the following:
•
Set the MNPDelay to any integer value from 1 to 60 (units are minutes). If you want to disable this
option, set a value of zero instead.
•
Set the QueueDepth to one of the following values:
2|4|8|16|32|Automatic
Array category
The Array category has the following options:
