12 HP StorageWorks Disk System 2120 Installing the Disk System Hardware Requirements The following hardware is included with the disk system: One power cord comes with each disk system. Your host computer must have one of the following: ■ An on board LVD SCSI port ■ An LVD SCSI host bus adapter board installed in the host system such as A7173A, A6828A, A6829A, A5865A, A7059A, or A7060A. You can view a complete and current list of supported host bust adapters at http://www.hp.com/products1/serverconnectivity/support_matrices.html. The following accessory is available for your storage disk system: ■ C2364A High Density 68-pin Terminator for LVD or Single-Ended The DS2120 supports a maximum SCSI speed of U160. Connectivity to U320 initiators is supported if the speed of the U320 initiator is set to limit negotiations to U160 speed. U320 drives do not operate reliably or at acceptable performance levels at U320 speeds and are not supported at those speeds. This is due to limitations within the disk system and not the U320 disk mechanisms. Contact your HP support representative for assistance with the configuration. Preparing for Installation Before the disk system is ready for installation, its SCSI IDs must be set and the host system must be prepared to recognize the newly installed disk system. See your operating system administration manual for configuration procedures for the host bus adapter.
