RebuildPriority, ExpandPriority These options establish the priority for rebuild and expand functions. Each option has 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 Video performance options require SAAP ("About SAAP" on page 8). To optimize the controller performance for video, set values for the following options as indicated: DPOEnable = No ElevatorSortEnable = Yes IRPEnable = No In addition: • 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: • Array (on page 81) • Drive (on page 81) • DriveType (on page 81) HP Array Configuration Utility 80

RebuildPriority, ExpandPriority
These options establish the priority for rebuild and expand functions. Each option has 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
Video performance options require SAAP ("
About SAAP
" on page
8
).
To optimize the controller performance for video, set values for the following options as indicated:
DPOEnable = No
ElevatorSortEnable = Yes
IRPEnable = No
In addition:
•
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:
•
Array (on page
81
)
•
Drive (on page
