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)
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.
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.
Hardware event monitoring and real-time error reporting Clustering (NT) The HP Disk System 2300 is Microsoft® Cluster certified for a variety of solutions. For specific information about supported configurations, see the Hewlett-Packard Company or Microsoft web pages: http://hp.com http://microsoft.com Upgradability...
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.
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.
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.
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...
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.
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.
Hardware/Software Requirements The disk system is supported on the following operating systems: HP-UX 11.00 with HWE 0302 (March 2002 Patch bundles) or greater HP-UX 11.11 with HWE 0302 (March 2002 Patch bundles) or greater Linux Red Hat 6.2, 7.0, 7.1 Windows NT 4.0 (Advanced Server, Enterprise Edition) Windows 2000 (Server and Advanced Server) Microsoft Windows.Net (Server and Advanced Server)

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.
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.
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.
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.
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.
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...
Definitions The following terms have specific meanings in the context of this guide: High availability (HA) HA describes hardware and software systems that are designed to minimize planned and unplanned downtime. High availability is measured at the system level and stated as the percentage of time the system is in a state to do useful work;...
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.
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.

Installing PDUs The 19-inch PDUs and PDRUs can be installed vertically or horizontally in the rack. Choose PDU/PDRU locations with the following guidelines in mind: Place PDU/PDRUs within the reach of disk system cords. Place PDU/PDRUs vertically whenever possible. See sample installations in Figure 12 Figure 13.
Software Requirements Ensure that the minimum revisions of HP-UX extension software and online diagnostics are installed. These release packages enable CommandView SDM and EMS for the disk system. 1. At the host console, enter swlist | grep HWE and look for the following extension software according to the installed HP-UX revision: HP-UX 11.00 with HWE 0302 HP-UX 11.11 with HWE 0302...
Auto-Termination Auto-termination is disabled when a shunt is installed over both pins on the TP2 pinset. To enable auto-termination, remove the shunt entirely or move it to only one of the pins. The result must be open pins, as shown Figure 14.
Step 1: Gather Tools Once the electrical, software, and special V-class preparations are complete, collect the tools you need to install the disk system hardware: Torx T25 screwdriver Torx T15 screwdriver Small flat-blade screwdriver Step 2: Unpack the Product 1.

6. Tighten the center nuts to finger tightness. Figure 37. Center Nut Tightening 7. Tighten all screws to their final tightness using a driver. Tighten the screws that hold the rail to the columns first, before tightening the center slide nuts to their final tightness. Installation...
8. Repeat the procedure above for the other rail. 9. Insert the disk system (with disk modules and power supplies removed) onto the rails. 10. Move the disk system retention brackets to the frontmost set of mounting holes. This allows the disk system to install further back into the cabinet; and so, allows the cabinet doors (if present) to close properly.
11. Push the disk system back into the rack until the disk system retaining bracket is flush against the front column of the rack. 12. Bolt the disk system to the front column. Use the fifth hole from the top of the front of the rail. Figure 40.
Install the Disk System 1. Remove the power supply/fan modules to prepare the disk system for lifting: Loosen the screws in each extractor handle of each power supply/fan module with the chassis still in the box. Pull the extractor handles out from the center of the power supply to disengage the it from the midplane.
Step 4: Install BCCs The disk system comes with one or two BCCs, depending on the option purchased. If you are installing only one BCC, you will install a BCC filler in the open BCC slot. 1. Attach your ESD strap to ground. 2.
9. If you do not have a second BCC, install the BCC filler as follows: Unpack the BCC filler from the accessories box. Align the filler panel edges with the appropriate slot and insert the filler into the open slot until the cam handles engage. Press the cam handles toward the center of the BCC until they are against the face of the filler panel.
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.
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.
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.
Step 8: Turn on the Disk System Caution When starting up the disk system, do not override automatic spin- up by issuing SCSI start commands to the drives. Doing so could cause an overcurrent fault, requiring a power cycle to recover. Press in the power/standby switch with the retracted tip of a pen or pencil to power-on the array (see Figure...
Step 9: Verify Devices on the Host On an HP-UX host run IOSCAN (ioscan -f) and verify that the disks and BCC(s) are listed in IOSCAN output. If the displayed “S/W State” is not “claimed,” begin troubleshooting (see Chapter 4). Sample IOSCAN The example shows a fully loaded disk system.
The “descriptions” in this example represent some of the valid disk modules. Valid disk descriptions include: ST318404LC18-Gbyte 10K rpm LVD disk module ST318406LC ST336704LC36-Gbyte 10K rpm LVD disk module ST336706LC ST373405LC73-Gbyte 10K rpm LVD disk module ST318452LC18-Gbyte 15K rpm LVD disk module MAM3184MC ST336752LC36-Gbyte 15K rpm LVD disk module MAM3367MC...

Setting DIP Switches Two DIP switches on left slot BCC determine bus architecture and some bus behavior. If that BCC is removed, then the DIP switches on the other BCC define the bus. See Table 8 for a description of switch settings.
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.
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.
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.
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. To install and configure the required monitors, refer to the EMS Hardware Monitors User’s Guide, which is included in Adobe Acrobat format on IPR Support Media.

Overview The following steps will help you identify and resolve disk system failures: Gather information from all sources: — Hardware event notifications (page 97) — Disk system LED status (page 101) — Online information tools (page 104) Isolate the cause of the problem (page 104). Correct the problem (chapter 5, Removal and Replacement).
Event Notification (HP-UX Systems) The EMS hardware event monitor polls environmental services on the BCC and reports any changes in the status of monitored components. Depending on how the monitor is set up, you can receive messages at the console, in e-mail, in a log file, or through third-party applications.
Page 98
Event messages (see Figure 50) contain the following: Message Data – Date and time the message was sent, the source and destination of the message, and the severity level Event Data – Date and time of the event, the host, event ID, name of the monitor, event number, event class, severity level, hardware path, associated OS error log entry ID Error Description –...

Removal and Replacement Caution Do not remove hot-pluggable components until you have the replacement parts and are ready to install them. An empty slot will cause uneven cooling and eventual overheating. Caution Do not move the disk system with disks installed and power on. Even a one-inch drop of the disk system can damage spinning disks Removal and Replacement 107...
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.
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:...
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.
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.
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.
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.
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.
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.
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”...
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.
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.
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.
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.
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.

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.
Top Cover (HP-Qualified Only) The following procedure is for HP-qualified personnel only. Remove and replace the top cover (not a replaceable part) in order to replace the power switch assembly, light pipes, or the midplane. You will need to turn the power off to perform this procedure. Tools Small flat-blade screwdriver Torx T25 screwdriver...
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.
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.

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.
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. Follow the procedures below to remove and replace the deskside conversion kit: Powering Down the Disk System Complete the appropriate system administration tasks for taking this storage device offline for your operating system.
Rotate the disk system and place it on its top. Remove the four M5 screws from the array chassis using a Torx T25 driver. They are the four screws that are closest to the center of the base. See Figure 62. Removal and Replacement 135...

Reinstalling the deskside base and external covers on the disk system. Place the deskside external cover on its top, on a sturdy surface. Lift the disk system chassis into the cover, onto the alignment pins. The disk system should be installed into the cover with the power switch down (toward the closed part of the cover).
Rotate the disk system and place it on the back end of the disk system. The empty disk module slots should be facing up. Align the end cap tabs into the appropriate slots at the top of the disk system. Rotate the end cap down over the base, aligning the small tabs at the top of the end cap with the end cap slots.
