HP Configuring Arrays Reference Manual page 82

You can use this option to prevent stale cache issues.
ClearConfigurationWithDataLoss
Clearing the configuration causes data loss because it deletes all logical volumes and arrays on the
controller. If you clear a configuration, you can write commands later in the script file to create a new
configuration from the liberated drive capacity.
The values for this option are Yes or No. The default value is No.
DriveWriteCache
This option controls the settings of the write cache for all connected physical disks. For this option, the setting
is Enable or Disable. Not all physical disks or controllers support this option.
LicenseKey, DeleteLicenseKey
These options enable you to enter a 25-character license key to activate or uninstall some controller features.
Hyphens can be entered, but are not required.
NoBatteryWriteCache
With this option, the controller can enable write cache when no battery is present or when the battery fails.
Values are Enable or Disable. The default is Disable.
Some controllers do not support this option.
PreferredPathMode
The setting that you select for this option determines how the preferred I/O path to a particular logical drive
is set for a redundant array controller that is in an active/active configuration.
Not all controllers support this feature, and controllers in an active/standby configuration disregard this
option.
•
Auto is the default setting for new configurations. In this case, the storage system automatically selects
the I/O path from the redundant controller to the logical drive and dynamically load balances all paths.
•
Manual enables you to assign the logical drive to a specific redundant controller. If you select this
setting, use the PreferredPath (on page 88) command to specify the path.
If you are reconfiguring a controller and do not specify a setting for this option, the existing setting remains
unchanged.
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.
