Product Description 1 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. Maximum data throughput is 160 Mbytes/sec. Thirteen disk systems fill a 2-meter System/E rack.
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) ■ Windows NT 4.
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
Product Description 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.
Power/Standby Switch Located at the upper right corner of the front of the disk system, the power switch (D in Figure 1) interrupts DC power from the power supplies to the BCCs and other internal components. Input AC power to the power supplies is controlled by the power cords and the AC source. High Availability High availability is a general term describing computer systems that are designed to minimize planned and unplanned downtime.
Environmental Services Product Description Environmental services circuitry monitors the following elements: ■ Fan rotation ■ Power supply output ■ Power supply status (fan status) ■ Disk drive status, presence ■ BCC status ■ Temperature ■ Self-test results Each BCC reports the status of all elements in the disk system, even if the BCC does not have direct access to the element.
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. The disk module’s components are protected by a metal grill on the disk module’s bottom side. WARNING Disks require careful handling and ESD precautions.
Product Description 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. The two SCSI buses are bridged. If either BCC fails and LVM primary and alternate paths are defined, data can be accessed through the other 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) 20 Product Description
BCC circuitry provides the following functions: ■ 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. Caution The BCC filler panel maintains even cooling inside the disk system when the second BCC is not present. A BCC filler panel must be installed if the BCC is removed.
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). Internal control prevents the rear DC output connector from becoming energized when the power supply is removed from the disk system.
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. The power supply fan remains on if other parts fail in order to maintain cooling air flow through the system. If the fan fails, the power supply shuts down. The fan in the other working power supply will increase to full speed to compensate for the failed fan.
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) ■ SCO UnixWare 7.11 ■ SCO OpenServer 5.06 ■ HP MPE/iX 7.

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. For information about specific supported topologies, consult an HP sales representative. This disk system can hold up to 14 disk modules.
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. If one of the disk systems fails in this topology, all hosts will still have access to the data on the mirrored disk system. All connections from the host to the disk system are SCSI LVD cables.
Product Description 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. This configuration can also do basic mirroring across different hardware paths, still providing a maximum data capacity of approximately 0.5 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. This configuration provides protection against any single component failure (i.e., cables, HBAs, disks). Figure 9 depicts connecting two disk systems to a single host.
Product Description 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. Each host can operate independently of the other. System reboots and shutdowns do not need to be coordinated between the hosts. In a split bus configuration, the two SCSI buses are physically isolated.
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.
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; for example, 99.95% availability translates to four hours of downtime per year.
Ultra160 SCSI Ultra160 is a SCSI interface that transfers 160 Mbytes/sec for wide busses.

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, autotermination is enabled on the host bus adapter. This section covers all three of these topics.
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. For example, to install more than four disk systems in Hewlett-Packard Rack Systems/E (HP Models J1500A(1.

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 and Figure 13. Installing PDU/PDRUs horizontally interferes with the ability to service disk systems that are behind the PDU/PDRU.

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 2.
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 in Figure 14. Verify that auto-termination is enabled on the host system. For other HBAs, check the documentation for your particular host bus adapter.
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.

2. Study the installation overview (see Figure 18). Installation The following tools are required for the installation of the storage device: ■ Flat-blade screwdriver ■ T25 nut driver WARNING To ensure cabinet or rack stability and avoid possible injury, always install the storage devices in the rack or cabinet from the bottom up.
3. Locate a place on the rack columns with the available space required for the installation of the storage device. The storage device and the rail kit require 3 EIA units of space. Use the following table as a guide for placement of the rails in a Rack System/E where multiple disk systems will be installed. You can rack multiple disk systems without gaps installing rails every three EIA units.
Installation 4. Install clipnuts as shown in Figure 20. Figure 20.
5. Insert the rail tabs into the appropriate column holes (see Figure 21). 6. Secure the rail ends with one M5 screw each. 7. Install clipnuts on the front columns of the cabinet (see Figure 22). These are used for the retention bracket screws.
Installation 8. Place the storage device on the rails and slide it into the cabinet until the retention bracket comes in contact with the rack column (see Figure 23). WARNING An empty storage device weighs more than 54 pounds (24.5 kg) (without disk modules installed). To avoid personal injury, it is recommended that two people install the storage device in the rack.
9. Insert and tighten the storage device retention (M5) screws through the retention bracket (see Figure 23).
10. Place a rail clamp on each rail and slide them to each bottom rear corner of the storage device.(see Figure 24). 11. Secure the clamps to the rails. Use one 10-32 screw for each rail clamp.
Installing the storage device into an HP Computer Cabinet Your storage device can be installed into the following Computer Cabinets: ■ C2785A Computer Cabinet (1.10M; 21U) ■ C2786A Computer Cabinet (1.60M; 32U) ■ C2787A Computer Cabinet (1.96M; 41U) Caution To ensure proper installation, only use the instructions in this manual for installing the storage device in the HP Computer Cabinet. Do not use the instructions enclosed in the rail kit box. 1. Check the rail kit contents (see Figure 25).
2. Study the installation overview (see Figure 26) Installation The following tools are required for the installation of the storage device: ■ Flat-blade screwdriver ■ T25 nut driver WARNING To ensure cabinet or rack stability and avoid possible injury, always install storage devices in the rack or cabinet from the bottom up. 3.

Installation
4.
5. Insert the rail tabs into the appropriate holes on the HP Computer Cabinet columns (see Figure 29). 6. Secure the rail ends with one M5 screw each. Figure 29.
7. Install clipnuts on the front columns of the cabinet (see Figure 30). These are used for the device retention screws. Installation 8. Place the storage device on the rails and slide it into the cabinet until the retention bracket comes in contact with the rack column (see Figure 31). 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.
9. Tighten the storage device retention (M5) screws through the retention bracket (see Figure 31).
10. Install a filler panel in the space below the storage device. If a filler panel is required, it must be ordered separately. Contact your local HP sales representative for assistance.
Installing the Storage Device into a Rittal-Style Rack Your storage device can be installed into the Rittal-Style Rack by doing the following steps: 1. Inspect the contents of the rail kit. If any parts are missing, call your nearest HP sales office. See Figure 33.
2. Align the front of rails to the inside of the front cabinet column. Carefully observe the alignment of the groups of holes on the columns so the holes in the rails align properly.
3. Insert and finger tighten the rail mounting screws. Use the third and seventh holes from the top of rail to mount the rail to the front column of the cabinet. 4. Extend the adjustable slide to the back column of the cabinet. 5. Insert the mounting screws and finger tighten them through the rear column of the cabinet.
Installation 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.
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.
Installation 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: a Loosen the screws in each extractor handle of each power supply/fan module with the chassis still in the box. b Pull the extractor handles out from the center of the power supply to disengage the it from the midplane. Pull each power supply/fan module out of the chassis. Support the far end of the power supply/fan module with your free hand as it clears the chassis.
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. Unpack the BCC from the accessories box and ESD bag. WARNING Do not touch the pins on the back of the BCC. 4. Open the BCC cam latches (C in Figure 41) by pulling them away from the center. 5.
8. If you have a second BCC, repeat steps 2 through 6, installing the second BCC in the right slot.
9. If you do not have a second BCC, install the BCC filler as follows: a Unpack the BCC filler from the accessories box. b Align the filler panel edges with the appropriate slot and insert the filler into the open slot until the cam handles engage. c Press the cam handles toward the center of the BCC until they are against the face of the filler panel. d Tighten the locking thumbscrew (see Figure 42).
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. Set dip switches as needed. See Chapter 3, Configuration, for switch definitions and guidelines.
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. Attach an LVD terminator to any empty SCSI port that is on a BCC with a cable attached. The terminators can be found in bags tethered to the BCC locking thumbscrew(s). 5. Attach the other end of each power cord to a preinstalled PDU/PDRU.

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. In addition, static electricity can destroy the magnetic properties of recording surfaces.
2. Put on the ESD strap and attach the other end to ground. Caution Disk modules are fragile. Handle carefully. Be careful to grasp the disk module by its handle and avoid touching exposed circuitry. 3. Verify that the disk module extraction handle (A in Figure 46) is open by placing a finger behind the extraction handle and pushing the latch tab toward your finger. 4. Align and insert the disk module into its slot. 5. Push the disk module as far as it will go into the selected slot.
Step 8: Turn on the Disk System Caution When starting up the disk system, do not override automatic spinup 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 47). Allow 2 minutes for the disk drives and controllers to complete their self-tests. 1. Press the power switch (A in Figure 47) to turn on the disk system. 2.
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 BCC card is at hardware path 0/1/0/0.15.
The “descriptions” in this example represent some of the valid disk modules.

Viewing a Disk System in IOSCAN An IOSCAN (example below) shows each BCC (0/1/0/0.15.0) and disk in the disk system. Sample IOSCAN Type the command: ioscan -f Class I H/W Path Driver S/W State H/W Type Description ============================================================================== ext_bus 4 0/1/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60001 target 6 0/1/0/0.0 tgt CLAIMED DEVICE disk 34 0/1/0/0.0.0 sdisk CLAIMED DEVICE HP 18.2GST318406LC target 7 0/1/0/0.
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. Table 8. DIP Switch Settings Switch Bank 1 Off - | ON = 0 Creates a single bus of up to 14 disk drives Splits the bus into two buses, up to 7 disk drives each 2 SES/SAF-TE SAF-TE Mode (SAF-TE mode is the default.
Configuration
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. Table 9. DIP Switch Usage Switch 1 1. Full Bus Reasons to Set OFF (|) a. Split buses allow you to mirror disks within the disk system. b.
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 fullbus 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. Disk Slots and Addressing In full bus mode, the SCSI address 7 is reserved for the host bus adapter.
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. You can download a copy of Acrobat Reader without charge from http://www.adobe.

Overview The following steps will help you identify and resolve disk system failures: 1 Gather information from all sources: — Hardware event notifications (page 97) — Disk system LED status (page 101) — Online information tools (page 104) 2 Isolate the cause of the problem (page 104). 3 Correct the problem (chapter 5, Removal and Replacement). 4 Verify operational status with IOSCAN or other host utilities.
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.

Removal and Replacement
Table 13. Part No. FRU Description Exch/ Repl.
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. Preparation (HP-UX 11.XX) Removing or replacing a disk has consequences for the file systems and logical volumes located on the disk.
At the host console, enter: # vgdisplay For example: #vgdisplay /dev/vg00 If the volume group is not active, the host will display: # vgdisplay: volume group not activated.
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.
For example: 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. 1 Replace the disk (see page 115). 2 Execute IOSCAN to verify that the replaced disk is accessible and a proper replacement disk. 3 Enter the vgcfgrestore command to restore the LVM configuration/headers to the replaced disk from the backup of the LVM configuration.
9 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. 1 After installing the disk module, execute the “Disk Management” utility to configure the disk module. 2 To execute the utility: select Start −> Programs −> Administrative Tools −> Computer Management. 3 Select “Disk Management”.
empty slot will cause uneven cooling and eventual overheating. 1 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. WARNING High current available. Avoid touching the midplane or adjacent drive electronics when removing and inserting disk modules.
Removal and Replacement 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. 3 Remove the replacement disk module from its ESD bag, being careful to grasp the disk module by its extraction handle (see Figure 53). (Fillers are not in ESD bags.
6 Press the extraction handle to seat the disk module firmly on the midplane. An audible click indicates the disk module is fully seated. 7 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. If you observe different results, refer to Chapter 4, Troubleshooting, for probable causes. 8 Run IOSCAN on the host and verify that the replacement disk module is “claimed.
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. Refer to Preparation (HP-UX 11.XX) on page 110.
6 Remove the replacement BCC from its ESD bag. Caution Switches must have the same settings on both BCCs. 7 Open the cam levers (see Figure 54) of the replacement BCC by pulling them away from the center of the card. 8 Insert the BCC in the empty slot. 9 Push the cam levers flat against the center of the card to seat the BCC pins firmly on the midplane.
11 Tighten the locking screws (B in Figure 54). 12 Reattach the SCSI cable and terminator. Caution The BCC must be replaced or a filler panel installed in the open slot to ensure proper cooling for the disk system. Removal and Replacement 121 Removal and Replacement 10 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.
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 122 Removal and Replacement Do not remove the malfunctioning BCC until you have available either a BCC filler panel or a replacement BCC.
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. The power supply fan may continue to operate even when a power supply fails. You do not need to turn off the disk system to replace a power supply.
5 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. 6 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. The power supply should be flush with the edge of the chassis. 7 Tighten the thumbscrews on the power supply handles (A and B).
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. The disk system must be turned off in this procedure. Caution Do not move the disk system with disks installed and power on.
7 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. 8 Push the disconnected disk system forward or lift it completely out of the rack, as needed. 9 When you are ready to replace the disk system, push the chassis back into the rack.
10 Insert and tighten the front mounting screws. 12 Reinstall the disk modules in the slots from which they were removed. 13 Reconnect SCSI cables and power cords. 14 Push the power button in to turn on the disk system. 15 Perform necessary system administration to return file systems to service. Removal and Replacement 127 Removal and Replacement 11 Reinstall the power supply/fan module(s).
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 ■ Torx T10 screwdriver Procedure Caution Disk slots must be empty before removing the top cover.
Removal and Replacement To reinstall the top cover: 1 Insert the edge of the top cover under the outer sheet metal of the chassis. 2 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. 3 Insert the three Torx T10 screws through the holes as shown in Figure 59. 4 Tighten the three Torx T10 screws. 5 Reinstall the disk system in the rack. See page 125. 6 Reinstall the disk system retention screws to secure the disk system.
8 Reinstall the power and SCSI cables. 9 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.
3 To remove the midplane: Loosen the cam handle locking screws and pull power supplies free of the midplane (see page 123). b Loosen the cam handle locking screws and pull the BCCs free of the midplane. c Remove the disk modules and fillers from the chassis. d Remove the light pipes (see Figure 60 on page 132) from the chassis. e Remove the power switch extender arm. f Remove the eight Torx T15 screws along the top and bottom edges of the midplane (see Figure 60).
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 1 Complete the appropriate system administration tasks for taking this storage device offline for your operating system. 2 Power down the disk system. 3 Disconnect the power cord(s) and SCSI cable(s).
5 Rotate the disk system and place it on its top. Removal and Replacement 135 Removal and Replacement 6 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.
7 Remove the four M5 screws from the cover using a Torx T25 driver. They are the four screws that are closest to the edges of the base. Figure 63.
8 Lift the disk system chassis off the alignment pins and out of the cover.
Reinstalling the deskside base and external covers on the disk system. 1 Place the deskside external cover on its top, on a sturdy surface. 2 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). 3 Secure the base to the cover using four M5 screws. Tighten the screws using a Torx T25 driver. They are the four screws that are closest to the edges of the base.
Removal and Replacement 5 Rotate the disk system and place it on the back end of the disk system. The empty disk module slots should be facing up. 6 Align the end cap tabs into the appropriate slots at the top of the disk system. 7 Rotate the end cap down over the base, aligning the small tabs at the top of the end cap with the end cap slots. Insert and tighten the M5 retaining screws using the Torx T25 driver. Be sure the retaining screw holes are aligned (see Figure 67).
