RaidArrayId
This option specifies the RaidArrayId for controllers that support this feature, such as fibre and shared storage
controllers. The RaidArrayId is a user-defined string that identifies controllers.
"XXXXXXXXXXXXXXXXXXXX"
The value can be a string of varying length that consists of any of the following characters:
a-z A-Z 0-9 ! @ # * ( ) , - _ + : . / [space]
This string cannot end in a space character.
This string has a maximum length that varies depending on the type of controller. For RA4x00 controllers, the
maximum length is 24 characters. For other controllers, the maximum length is 20 characters.
The quotes enclosing the string are optional. The quotes allow you to use leading space characters in the
RaidArrayId.
ReadCache, WriteCache
Enter a number between 0 and 100 to specify the percentage of cache that is to be allocated to drive reads
or writes. The default value for both options is 50, depending on the controller and the battery status.
The allowable cache ratios depend on the controller model and whether it has battery-backed write cache,
as described in the following table.
A "+" indicates that the specified cache ratio is allowed for that type of controller, while a "–" indicates that
the ratio is not allowed.
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.
