ChassisName Enter the user-defined character string that identifies the controller. You can use any of the following characters in the string: a-z, A-Z, 0-9 space] You do not need to use quotation marks around the string, but doing so allows the string to begin with a space character. However, the string cannot end with a space character. Currently, only shared-storage controllers such as the RA4x00, MSA1000, and Smart Array Cluster Storage support the ChassisName option. The RA4x00 controller uses a 24-character string, while other applicable controllers use a 20-character string. ClearConfigurationWithDataLoss This command is now deprecated. The default value for this option is No. 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. 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. 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 command to specify the path. If you are reconfiguring a controller and do not specify a setting for this option, the existing setting remains the same. ReadCache, WriteCache Enter a number between 0 and 100 to specify the percentage of cache to be allocated to drive reads or writes. The default value for both options is 50. 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. Read:write ratio 100:0 90:10 80:20 75:25 RA4x00 with 16MB cache + + + - RA4x00 with 48MB cache + + + - All other controllers with battery-backed write cache + - - + All other controllers without battery-backed write cache + - - - Using HPACUSCRIPTING 35
