Page 11: Product Description
Product Description General Description Hewlett-Packard’s StorageWorks Disk System 2300 (referred to in this guide as the disk system) is a high-availability Ultra160 SCSI storage product. Dual SCSI ports on dual bus controllers provide LVD connections to the host. Fourteen slots accept high-speed, high-capacity LVD SCSI disks connected to an LVD midplane.
Page 12 HP Command View SDM (Software Device Manager) software is designed to provide storage management for HP disk systems. This software, available on the HP Command View SDM CD-ROM, provides simple, yet sophisticated device management tools for the disk system. HP Command View SDM is supported on the following: HP-UX 11.00 (see Support Plus web site for the required patches) HP-UX 11.11 (see Support Plus web site for the required patches)
Page 13: Features
Features The disk system occupies 3 EIA units in a standard 19-inch rack. Disk drives mount in the front of the system. Redundant power supplies, and BCCs mount in the back. See Figure 1 and Figure 2 below. For disk slots and SCSI addressing, see Figure 49.

Product Description...
Page 15: Status Indicators
Status Indicators LEDs on the disk system enable you to detect and replace failed components and so prevent or minimize users’ downtime. For additional information about LEDs, see Chapter 4, Troubleshooting. On the front of the disk system, a pair of LEDs indicates the status of the disk system, and an LED for each slot shows disk I/O activity: The system power LED (B in Figure 1) indicates that power is on or off.

Page 17: Environmental Services
Hardware Event Monitoring A hardware event monitor monitors the disk system and reports changes in environmental status to Hewlett-Packard’s Event Monitoring System (EMS) for HP-UX. Hardware event monitoring is an important tool for implementing high availability. Using hardware event monitors, you can virtually eliminate undetected hardware failures that interrupt system operation or cause data loss.
Page 18: Components
Components User-replaceable components enable high availability and easy maintenance. This section describes the following components: Disks and disk fillers BCCs and BCC fillers Power supply/fan modules Disk Modules and Disk Module Filler Panels Disk modules, shown in Figure 3, contain 3.5-inch Low Profile Ultra 3 LVD disks.
Page 19: Bccs And Bcc Filler Panels
BCCs and BCC Filler Panels BCCs (Bus Control Cards) plug into two slots in the back of the disk system. Each BCC connects to both LVD (low voltage differential) buses inside the disk system. In full bus mode (DIP switch 1 set to “|”), both BCCs have access to all installed disks.
Page 20: Figure 4 Bcc
Other features of the BCC are: LEDs (C) indicating BCC status and bus configuration DIP switches (D) on the rear panel: 1 Bus Mode (full or split bus) 2 Monitor Mode (SAF-TE or SES) Locking thumbscrews (E) Cam levers (F) Product Description...
Page 21: Figure 5 Bcc Filler Panel
BCC circuitry provides the following functions: Bus configuration (see “Setting DIP Switches” in Chapter 3) Bus expansion (LVD) SCSI environmental services (see page 17) System fault detection A BCC filler panel (Figure 5) replaces the second BCC when redundancy is not required.
Page 22: Power Supply/Fan Module
Power Supply/Fan Module Redundant, hot-pluggable 340-watt power supplies convert wide-ranging AC voltage from an external main to stable DC output and deliver it to the midplane. Each power supply has an internal fan, an AC receptacle (A in Figure 6), two ejector handles (D) with thumbscrews (C), and 2 LEDs (B).
Page 23 Power supplies share the load reciprocally; that is, each supply automatically increases its output to compensate for reduced output from the other, and vice versa. If one power supply fails, the other delivers the entire load. Internal circuitry triggers a fault when the internal fan or other part fails. At the same time, the power fault LED (amber) illuminates, and, if enabled, the hardware event monitor sends an event message.
Page 24: Hardware/Software Requirements

Page 27: Topologies
Topologies The disk system supports high availability through redundant components and redundant connections to redundant hosts. Each SCSI port on a BCC can be connected to a different host bus adapter in the same or different hosts. Internal mirroring within the disk system is also possible. Basic high availability topologies are described on the following pages.
Page 28: Figure 7 Basic Configuration - Single Host, Single Disk System
Another type of high availability topology connects mirrored disk systems to redundant hosts. Dual host bus adapters in each host are connected to mirrored disk systems. With the disk systems in full bus mode (switch 1 on), each host can reach all disks in both disk systems.
Page 29: Figure 8 Single Host, Split Bus Configuration
The disk system can be connected to a single host with two host bus adapters (HBAs) in a split bus configuration. See Figure 8. Each HBA will do reads and writes to a maximum of seven disks. This configuration can provide a maximum capacity of approximately 1.1 Terabytes.
Page 30: Figure 9 Single Host Pv-Links Configuration
Data path redundancy can be secured with the configuration shown in Figure 9. Using an additional host bus adapter (HBA) and the LVM software, alternate links can be created, providing a redundant path to data for each disk system. In addition, a separate mirror path can be created for data protection.
Page 31: Figure 10 Two Host Non-High Availability Configuration
For customers with small data storage needs, a single disk system can be connected to two hosts in a split bus mode. Each host can do reads and writes to a maximum of seven disk modules. Each BCC can provide disk system status to the host it is connected to.
Page 32: Figure 11 Two Host High Availability Configuration
A two-host configuration could be constructed using the Disk System 2300. Each disk system could still be configured using mirrors. High availability software will protect against a system failure. See Figure 11, above. Product Description...

Page 36: Preparation
Preparation Before installing the disk system, make sure (1) electrical wiring, breakers, and PDUs meet power needs, (2) the required support software is installed on the host, and (3) if you are connecting the disk system to a V-class server, auto- termination is enabled on the host bus adapter.
Page 37: Choosing Pdus
Circuit breakers must be adequately rated for inrush and operating currents. Hewlett-Packard recommends magnetic-type circuit breakers, which are capable of handling large inrush currents for short durations (10 to 12 cycles) and are rated adequately for steady state currents. Choosing PDUs Peak power requirements and PDU capacity affect the number of disk systems that can be installed in a rack.

Page 74: Step 5: Set Dip Switches
Step 5: Set DIP Switches BCCs are shipped from the factory with all DIP switches (see Figure 43) in the “|” position. The pull-out label on top of the disk system identifies each switch position. Caution DIP Switch settings must be the same on both BCCs. If settings differ, the disk system will fail its power-on self-test and the disks will not be accessible through the second BCC.
Page 75: Step 6: Connect Scsi And Power Cables
Step 6: Connect SCSI and Power Cables 1. Attach an LVD SCSI cable to SCSI port A or B, on one or both BCCs. (Sample topologies appear in Chapter 1.) 2. Attach the other end of each SCSI cable to a host bus adapter. (See bus configuration options in Chapter 3.) 3.

Page 78: Step 7: Install Disk Modules
Step 7: Install Disk Modules Caution Touching exposed areas on the disk can cause electrical discharge and disable the disk. Be sure you are grounded and be careful not to touch exposed circuits. Disk modules are fragile and ESD sensitive. Dropping one end of the disk just two inches is enough to cause permanent damage.
Page 79 1. Determine which slots, 1 through 14, will contain disk modules and which will contain fillers. — If DIP switch 1 is set to “|” (full bus mode), choose any slots for disk modules or fillers. In full bus mode, the SCSI address 7 is reserved for the host bus adapter.
Page 80: Step 8: Turn On The Disk System

Page 87: Rationale
Rationale Sites choose DIP switch options according to their priorities and preferences. High availability sites, for example, may want automatic bus reset on whereas high performance sites may choose to turn it off. The following table gives some of the typical reasons for choosing specific DIP switch settings.
Page 88: Disk Addressing
Disk Addressing Each disk in the StorageWorks Disk System 2300 occupies a separate address (SCSI ID) on the SCSI bus. Disk addresses range from 0 to 6 and 8 to 14 in full- bus mode (DIP switch 1 set to “|”). In split bus mode (DIP switch 1 set to “0”), the left BCC (viewing the disk system from the rear) is on the high numbered bank (with disk slots 8, 9, 10, 11,12, 13, and 14) and the right BCC is on the low numbered bank (with disk slots 0, 1, 2, 3,4, 5, and 6) of disk slots.
Page 89: Disk Slots And Addressing
Note In split bus mode, the enclosure monitor circuitry on each BCC utilizes SCSI address 15. This is allowable since each BCC is connected to a separate SCSI bus. However, when the enclosure configuration is in Full Bus mode, and the separate SCSI busses on the midplane are connected together and there are two BCCs in the enclosure, the secondary BCC does not connect to the SCSI bus.
Page 90: Setting Up The Hardware Event Monitor
Setting Up the Hardware Event Monitor Separate monitors watch over the disks and the disk system. You need to install and configure the Disk Monitor (disk_em) and the High Availability Storage System Monitor (dm_ses_enclosure) for complete event notification.

Page 110: Disk Module
Disk Module Add or replace disks to increase storage capacity or eliminate faults. (See Chapter 4 for troubleshooting procedures.) Disks must be Ultra-3 SCSI (LVD) and 3.5 inches wide but can vary in capacity. For current information about supported disks, consult an HP sales representative. You do not need to turn off the disk system to replace a disk or filler.
Page 111: To Determine If A Volume Group Or Physical Volume Group Is Active
To Determine If a Volume Group or Physical Volume Group Is Active At the host console, enter: # vgdisplay <VG name> For example: #vgdisplay /dev/vg00 If the volume group is not active, the host will display: # vgdisplay: volume group not activated. # vgdisplay: cannot display volume group /dev/vg00 The following messages will appear if the disk is defective:...
Page 112: To Replace Attached Physical Volumes
To Replace Attached Physical Volumes Use the following commands to reduce any logical volumes that have mirror copies on the faulty disk and to recreate the mirror extents once the disk has been replaced. Commands to recover from a host failure are included with most steps. Note The way that mirrors span several disks may not be duplicated exactly.
Page 113 For example: # vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t4d0 If the host fails, repeat the step to ensure all configuration data is written to the new disk. Note If this replacement procedure is being performed now on another host system and there is no need to execute any lvreduce commands, then the configuration file can be updated with the vgcfbackup command.
Page 114: To Replace Unattached Physical Volumes
To Replace Unattached Physical Volumes Follow these instructions if the volume group is not active or if the physical volume is unattached. Replace the disk (see page 115). Execute IOSCAN to verify that the replaced disk is accessible and a proper replacement disk.
Page 115: Windows 2000
Exit the “Disk Administrator” utility and execute explorer (right-click start and choose explorer). View the newly created drives and ensure all drives are shown. Windows 2000 Note The following instructions are for the configuration of a new disk module. They should not be followed to add a disk module with data to an existing disk system.
Page 116 empty slot will cause uneven cooling and eventual overheating. Release the disk from the slot by squeezing the latch tab (B) and pulling it toward you. Caution Spinning disks generate heat and gyroscopic force. Wait for a spinning disk to slow down and cool off before removing it from the product.
Page 117: Figure 53 Disk Module Removal
Caution Replace the disk module or filler immediately (see next step). Caution Touching the disk circuit board can cause high energy discharge and permanently damage the disk. Disk modules are fragile. Handle carefully. Remove the replacement disk module from its ESD bag, being careful to grasp the disk module by its extraction handle (see Figure 53).
Page 118 Press the extraction handle to seat the disk module firmly on the midplane. An audible click indicates the disk module is fully seated. If you are installing a disk module (as opposed to a filler), monitor the LED (D). It should be on while the disk spins up and then turn off. The LED will blink with I/O activity to the disk.
Page 119: Bcc
Replace a BCC when troubleshooting shows that the card is faulty (see “Isolating Faults” in Chapter 4). There is no need to turn off the disk system to remove and replace a BCC. In full bus mode with two BCCs, there is also no need to stop I/O to the disks. In other configurations, however, the host must be notified that all disks on the affected bus will be unavailable for I/O.
Page 120: Figure 54 Bcc Removal And Replacement
Remove the replacement BCC from its ESD bag. Caution Switches must have the same settings on both BCCs. Open the cam levers (see Figure 54) of the replacement BCC by pulling them away from the center of the card. Insert the BCC in the empty slot. Push the cam levers flat against the center of the card to seat the BCC pins firmly on the midplane.
Page 121: Figure 55 Bcc Dip Switches
Watch the BCC Fault LED (B in Figure 55). It should come on briefly and then turn off. If the LED stays on and a buzzer sounds, the switch settings do not match the settings on the peer BCC. For other solutions to a BCC fault, see “Isolating Causes”...
Page 122: Bcc Filler Panel
BCC Filler Panel If a BCC is removed and a new one is not available, the BCC slot must be filled to ensure proper cooling for the disk system. This is done with a BCC filler panel. For removal instructions for the BCC, see page 119. Caution Do not remove the malfunctioning BCC until you have available either a BCC filler panel or a replacement BCC.
Page 123: Power Supply
Power Supply Replace a power supply as soon as possible when troubleshooting indicates a power supply failure (see “Isolating Causes” in Chapter 4). If a power supply fails, the remaining power supply provides proper voltage to the disk system. However, if the remaining power supply fails before the first power supply is replaced, the disk system will turn off.
Page 124: Figure 57 Power Supply Removal And Replacement
Slide the replacement power supply into the empty slot (D in Figure 57). The power supply begins to engage the midplane with 3/8 inch (8mm) still exposed. Rotate the handles back toward the center of the power supply module to draw the power supply the last 3/8 inch into the chassis and firmly seat the power supply on the midplane.
Page 125: Disk System
Disk System Use this procedure if you need to move or remove and replace the disk system in the rack. For example, you must remove the disk system from the rack in order to replace the midplane or power switch assembly. 24 inches of vertical space is required in the rack if these units are to be replaced without removing the disk system from the rack.
Page 126: Figure 58 Disk System Removal And Replacement
Remove screws from the mounting ears (see detail in Figure 58). WARNING An empty storage device weighs approximately 54 pounds (without disk modules installed) (24.5 kg). To avoid personal injury, it is recommended that two people install the storage device in the rack.
Page 127 Insert and tighten the front mounting screws. Reinstall the power supply/fan module(s). Reinstall the disk modules in the slots from which they were removed. Reconnect SCSI cables and power cords. Push the power button in to turn on the disk system. Perform necessary system administration to return file systems to service.

To reinstall the top cover: Insert the edge of the top cover under the outer sheet metal of the chassis. Slide the cover toward the middle of the chassis, making sure to rotate the top cover down to align with the edges of the chassis. Insert the three Torx T10 screws through the holes as shown in Figure 59.
Page 130: Midplane (Hp-Qualified Only)
Reinstall the power and SCSI cables. Reinstall disks and fillers. See page 110. Midplane (HP-Qualified Only) The midplane board is replaceable by HP-qualified personnel only. Replace the midplane based on troubleshooting results (see “Isolating Causes” in Chapter 4). Disks, BCCs, fans, and power supplies connect to the midplane. The power must be OFF (out) and the top cover removed in order to remove and replace the midplane board.
Page 131 To remove the midplane: Loosen the cam handle locking screws and pull power supplies free of the midplane (see page 123). Loosen the cam handle locking screws and pull the BCCs free of the midplane. Remove the disk modules and fillers from the chassis. Remove the light pipes (see Figure 60 on page 132) from the chassis.
Page 133: Deskside Base/External Covers (Hp-Qualified Only)
Deskside Base/External Covers (HP-Qualified Only) The deskside base and external covers must be removed from the chassis before the top cover, the midplane, the light pipes, or the power switch extender arm can be replaced.
