HP Microsoft Windows Server 2003 for Itanium-based Systems manual Controller, RAIDArrayID

Controller

You must enter a value for this option because it identifies the controller that is to be configured.

•All—Configure all detected controllers in the system identically.

•Slot [N]—Configure the internal controller in slot number N.

•WWN [N]—Configure the external controller that has the World Wide Name N.

•SerialNumber [N]—Configure the shared storage controller that has serial number N.

•IOCabinet[N],IOBay[N],IOChassis[N],Slot[N],Cabinet[N],Cell[N]—Configure the controller in the Integrity server that has the slot path information defined by this sequence of identifiers.

ClearConfigurationWithDataLoss

The default value for this option is No. Clearing the configuration causes data loss because it deletes all logical drives 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.

RAIDArrayID

Enter the user-defined character string that identifies the controller. Any of the following characters can be used 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 RAIDArrayID option. The RA4x00 controller uses a 24-character string, while other applicable controllers use a 20-character string.

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. The allowable cache ratios depend on the controller model and whether it has battery-backed cache, as described in the table ("Allowable cache ratios" on page 35).

Allowable cache ratios

NOTE: Y indicates that the specified cache ratio is allowed for that type of controller, while -- indicates that the ratio is not allowed.

Read:write	RA4x00 with	RA4x00 with	All other controllers with	All other controllers
ratio	16MB cache	48MB cache	battery-backed cache	without battery-backed
				cache
100:0	Y	Y	Y	Y
90:10	Y	Y	--	--
80:20	Y	Y	--	--
75:25	--	--	Y	--
