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.

This parameter specifies the Surface Scan Mode with the following values:
•
Idle
—The delay interval is set with the normal values from
SurfaceScanDelay

.
•
High

•
