NOTE: The SSPState option is valid only for controllers that enable SSP on a controller basis, such as the MSA1000 or the Smart Array Cluster Storage controllers. RA4x00 controllers support SSP that is enabled on a logical drive basis, and use the LogicalDriveSSPState option (page 39) instead. If you enable SSP, you must also specify an adapter for one or more logical drives by using the SSPAdaptersWithAccess option (page 40). Otherwise, SSP is automatically disabled. SurfaceScanDelay Enter a number between 1 and 30 to specify the duration of the surface scan delay in seconds. Video performance options 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 any integer value from 2 to 32, or to Auto. Array category The Array category has the following options: • "Array" (page 37) • "Drive" (page 37) • "DriveType" (page 38) • "OnlineSpare" (page 38) Array Enter a letter or pair of letters to identify the array you are creating or reconfiguring, and observe these additional limitations: • In Configure mode, HP SSA creates a new array. The value that you specify for the array option must be the next available letter or pair of letters in the sequence, according to the number of existing arrays on the controller. AA follows Z, and BA follows AZ. • In Reconfigure mode, HP SSA can either create a new array or reconfigure an existing array. In this case, the value that you specify can identify an existing array, or it can correspond to the next available array letter or pair of letters in the existing configuration. Drive You can use this option to add a drive to an existing array (to expand an array) or to build a new array. If you are expanding an array, each drive that you add must have a capacity no less than that of the smallest drive already in the array. The added and existing drives in the array must all be the same type (for example, SAS or SATA). If the value of the ClearConfigurationWithDataLoss option is Yes, you can use the Drive option to remove drives from an array. However, the ClearConfigurationWithDataLoss option is now deprecated. If you use Auto method mode, HP SSA configures all the available drives on the controller into one array. If the drives are of different capacities, HP SSA determines the capacity of the smallest drive and uses the same amount of space on all other available drives. Using HPSSASCRIPTING 37

NOTE:
The SSPState option is valid only for controllers that enable SSP on a controller basis,
such as the MSA1000 or the Smart Array Cluster Storage controllers. RA4x00 controllers support
SSP that is enabled on a logical drive basis, and use the LogicalDriveSSPState option
(page 39)
instead.
If you enable SSP, you must also specify an adapter for one or more logical drives by using the
SSPAdaptersWithAccess option
(page 40)
. Otherwise, SSP is automatically disabled.
SurfaceScanDelay
Enter a number between 1 and 30 to specify the duration of the surface scan delay in seconds.
Video performance options
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 any integer value from 2 to 32, or to Auto.
Array category
The Array category has the following options:
“Array” (page 37)
“Drive” (page 37)
“DriveType” (page 38)
“OnlineSpare” (page 38)
Array
Enter a letter or pair of letters to identify the array you are creating or reconfiguring, and observe
these additional limitations:
In Configure mode, HP SSA creates a new array. The value that you specify for the array
option must be the next available letter or pair of letters in the sequence, according to the
number of existing arrays on the controller. AA follows Z, and BA follows AZ.
In Reconfigure mode, HP SSA can either create a new array or reconfigure an existing array.
In this case, the value that you specify can identify an existing array, or it can correspond to
the next available array letter or pair of letters in the existing configuration.
Drive
You can use this option to add a drive to an existing array (to expand an array) or to build a new
array. If you are expanding an array, each drive that you add must have a capacity no less than
that of the smallest drive already in the array. The added and existing drives in the array must all
be the same type (for example, SAS or SATA).
If the value of the
ClearConfigurationWithDataLoss
option is Yes, you can use the
Drive
option to remove drives from an array. However, the
ClearConfigurationWithDataLoss
option is now deprecated.
If you use Auto method mode, HP SSA configures all the available drives on the controller into one
array. If the drives are of different capacities, HP SSA determines the capacity of the smallest drive
and uses the same amount of space on all other available drives.
