HP StorageWorks Disk System 2120 7 Overview The DS2120 supports U320 drives; however, the U320 drives are supported at a maximum of 160 MB/s speeds. Connectivity to U320 initiators is supported if the speed of the U320 initiator is set to limit negotiations to U160 speed. The 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 drive mechanisms.
HP StorageWorks Disk System 2120 Components of the Disk System Front Panel The disk modules can be accessed from the front of the disk system. It can accept up to 4 low profile disk drives. If your storage system contains less than 4 disk modules, the remaining empty slots contain filler panels. These filler panels (part number A6198-60002) ensure that the proper cooling is maintained within the storage system. Remove filler panels only when a disk module is added to the system.

HP StorageWorks Disk System 2120 SCSI ID Switch The SCSI ID switch sets the address for the disk drives. There are three possible settings for the SCSI address switch: A, B, and C. Each setting assigns a different set of addresses to the disk modules installed in the disk system. For SCSI address switch setting A, the addresses for the installed disk modules are (from left to right, looking at the disk system from the front) 0, 2, 4, and 6.
HP StorageWorks Disk System 2120 11 Power Connector FIGURE 6 AC Power Connector Location English AC Power Connector Electrical Requirements AC Site Requirements Overcurrent protection devices are required for each cabinet where the disk system is installed. They must be positioned between the power source and the disk system. These protective devices must not trip when exposed to an inrush current of 30 amps lasting 5 ms.
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.
HP StorageWorks Disk System 2120 13 Setting the SCSI IDs for the Disk Modules 1 Determine which SCSI addresses are not being used on the host system. 2 Locate the SCSI switch on the back of the disk system. FIGURE 7 SCSI Switch Location C B A SCSI Address Switch Setting A B C Disk Module SCSI Addresses (Viewed from front of storage enclosure) 6 14 15 4 12 13 2 10 11 0 8 9 3 Set the SCSI IDs. Verify that the SCSI IDs you have chosen are available.
HP StorageWorks Disk System 2120 Keep in mind that the host bus adapter should have the highest SCSI address priority. See Table 5 below. TABLE 5 SCSI Address Priority SCSI ID 7 Priority 6 5 4 3 2 1 0 15 14 13 12 Highest 11 10 9 8 Lowest Installing the Disk System See the installation instructions enclosed with your rackmount kit. Connect the SCSI Cables 1 Make sure that the host system has been powered down.
HP StorageWorks Disk System 2120 15 4 Determine if this disk system is at the beginning or end of the SCSI bus. – If the disk system is at the beginning or middle of the SCSI bus (you are going to daisy-chain another device off this one), consider the following: • Due to SCSI ID restrictions, no more than two of these disk systems can be daisy-chained together. • For the DS2120, use only 0.5-meter cable between enclosures in daisy-chain configurations.
HP StorageWorks Disk System 2120 Connecting the Power Cable CAUTION FIGURE 9 Ensure that the connection of multiple units to the supply circuit does not overload the supply overcurrent protection or the supply wiring. Refer to the storage electrical ratings when determining the correct branch circuit rating for your installation. See Table 3 on page 11.
HP StorageWorks Disk System 2120 17 Power Off the Disk System 1 Back up all data if the disk system is still operational. 3 Unmount any file systems associated with the disk system that is going to be powered off. Refer to the system administration manual for your host system’s operating system for the correct procedure for unmounting a file system or stopping access to the disk modules within the disk system.
HP StorageWorks Disk System 2120 Adding Disk Modules Disk modules can be added, removed, and replaced while the disk system is running. Because the disk modules can be handled in this way, they are called hot-pluggable. The SCSI addresses for the disks are set using the addressing switches on the back of the disk system. You can determine the assigned SCSI addresses by looking at the SCSI address switch settings at the rear of the disk system.
HP StorageWorks Disk System 2120 19 FIGURE 11 Installing a Disk Module English Configure the new Disk Module Configure a new disk module within your application. CAUTION These procedures should be performed only by qualified system administrator. Performing hot-plug operations on an active disk drive can result in data loss or corruption.
HP StorageWorks Disk System 2120 2 Prepare the software environment to remove the drive. See your operating system documentation for instructions and procedures required to remove a disk module. It may be necessary to unmount file systems associated with the disk drives installed in the disk system. 3 Unlatch the disk module handle and remove the disk module. Squeeze the latch to unlock the disk module. Put a finger behind the latch and pull the disk module out until it disengages from the backplane.
HP StorageWorks Disk System 2120 21 Remove the Disk System Reverse the installation instructions enclosed with the rackmount kit for your cabinet: ■ ■ A7552A - Hewlett-Packard Rack Systems/E for Enterprise Systems A5680A - all other Hewlett-Packard rack systems for Enterprise Systems purchased before November 1998. If your disk system is a factory-integrated unit, see the figure below for removal instructions.
HP StorageWorks Disk System 2120 Setting Up the Hardware Event Monitor (HP-UX Only) Hardware event monitors run on HP-UX hosts, versions 10.20 and later. The Disk Monitor (disk_em) monitors all disks bound to sdisk drivers. Consequently, if the Disk Monitor is active on your host, it is already set up to monitor the disks of a new disk system. If you need to install or activate the Disk Monitor, refer to the EMS Hardware Monitors User’s Guide in the latest IPR Support Media or on the Web (http://www.
HP StorageWorks Disk System 2120 23 Event Notification (HP-UX Only) Event severity ranges from critical to informational: Critical An event that causes data loss, host system downtime, or other loss of service. Host system operation will be affected if the disk system continues to be used without correction. Immediate action is required. For example, read data could not be recovered. Serious An event that may cause data loss, host system downtime, or other loss of service if left uncorrected.
