LCC circuitry provides the following functions:
System fault detection Disk address generation
If an LCC fails, do not remove it from the disk system until you are ready to replace it with a new one. The failed LCC should remain installed to assure proper cooling for the disk system.

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 5), 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. Figure 5. Power Supply/Fan Module
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. 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. The failed power supply/fan module must be removed and the replacement power supply/ fan module installed within two minutes. In the event of a failure, if a replacement fan module/power supply is not available, leave the failed power supply/fan module installed until you are ready to replace it. This should be done to maintain proper cooling for the disk system. Internal circuitry senses fan motion and triggers a fault when the speed of the power supplys internal fan falls below a critical level. At the same time, the LED turns amber, 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 or greater HP-UX 11.11 with HWE 0302 or greater
For supported servers, see the latest HP 9000 Configuration and Ordering Guide. One of the following Fibre Channel HBAs must be installed in the host:
A5158A, 1 Gb PCI Fibre Channel HBA A6684A, 1 Gb HSC Fibre Channel HBA A6685A, 1 Gb HSC Fibre Channel HBA A6795A, 2 Gb PCI FIbre Channel HBA

Multimode A type of fiber optic cable that allows more than one mode (rays of light) to be guided. Arbitrated Loop (FC-AL) A Fibre Channel topology that provides a low-cost solution to attach multiple communicating ports in a loop without hubs and switches. Arbitrated Loop Physical Address (AL_PA) A unique one-byte valid value assigned during Loop Initialization to each NL_Port or FL_Port on a Loop.

Installation

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.

Preparation

Electrical Requirements
All electrical wiring to the service point (plug) must be sized to carry the appropriate inrush (20 amps per power supply) and steady state currents. See the following table for examples. Table 1. Inrush (Surge) Current and Duration No. of Disk Systems on Circuit (2 power supplies per disk system) 3 4
Inrush Current and Duration
40 amps declining over 100 ms (5 cycles) 80 amps declining over 100 ms (5 cycles) 120 amps declining over 100 ms (5 cycles) 160 amps declining over 100 ms (5 cycles)
Table 2. Maximum Operating Current Incoming Voltage AC RMS volts volts Caution Maximum RMS Current Drawn by One Disk System 4.8 amps 2.0 amps
Adding disk systems to 120V circuits rapidly increases amp requirements. Always make sure that the total current drawn does not exceed circuit capacity.
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 legacy racks (HP C2785A, C2786A, and C2787A), you must upgrade to 19-inch PDUs. Besides rack density, the following factors can help you choose PDUs:
Redundant power source. To connect redundant power supplies to separate
PDUs, install redundant PDUs.
Number of cords to the AC source. Using 30-amp PDRUs instead of 16-amp
PDUs reduces the number of cords to the wall.

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 Lift off the overcarton and verify the contents of the accessories (top) box. See Table 5 and Figure 12. Table 5. Disk System Accessories Figure Label A B C D E Part (part number) User guide (A6250-96010) Quick installation guide (A6490-96003) LCCs (A6255-60001) Disk Modules and/or Filler Panels Fibre Channel cable(s) Rail Kits (not shown)
2 Lift off the accessories box and the top of the under box, and verify the contents shown in Table 6 and Figure 13. Table 6. Disk System Contents Figure Label A B C Part (part number) Two power cords (8120-6514) FC Cables (Ordered separately) Disk system chassis with previously installed disk modules, link control cards, and power supply/fan modules
3 If a part is missing, contact an HP sales representative.
Step 3: Install the device
Follow the procedures in this section to install your storage device in one of the following rack systems:
HP Rack System/E HP Computer Cabinet Rittal-Style Rack
Installing the Storage Device into a Rack System/E
Your storage device can be installed into any of these HP Rack System/E Products:
A4900A HP Rack System/E25 (1.25 M; 25U) A4901A HP Rack System/E33 (1.60 M; 33U) A4902A HP Rack System/E41 (2.00 M; 41U)
1 Check the rail kit contents (see Figure 14). If any parts are missing, call your nearest HP sales office.
2 Study the installation overview (see Figure 15).
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 by installing rails every three EIA units. For example, starting at the bottom of a 2-meter rack, set rails at the following unit/hole locations: Table 7. Rail Positions for Sequential Disk Systems Disk Systems One Two Three Four Five Six Seven Eight Nine Ten Eleven 7

Hole from Rack Bottom

Be sure to use the same tabupper or loweron opposing rails. Also, hole patterns vary at opposite ends of the rails.

Step 4: Configure LCCs

The disk system comes with two LCCs installed. If you are connecting this disk system to an HP StorageWorks Virtual Array 7400 or to a 1 Gb/s hub, the link speed switch must be set to 1 Gb/s. 1 Attach your ESD strap to ground. 2 Remove the LCC from the disk system chassis. Caution Do not touch the pins on the back of the LCC.
3 Set internal configuration dip switch to appropriate link speed.
Be sure to set the internal LCC data transmission speed switch to 1 Gb/s or 2 Gb/s as appropriate for your configuration. See Figure 2.29 for more detailed information.
4 Open the LCC cam latches (B in Figure 39) by pulling them away from the center. 5 Align the LCC with the slot (D in Figure 39), and insert the LCC into the slot at the back of the disk system. Stop pushing when the LCC meets the midplane. 6 Press the cam latches inward and flat against the center. The cam action draws the LCC completely into the slot and seats the connector pins on the midplane. 7 Tighten the locking thumbscrews (C).
Repeat steps 2 through 7, installing the second LCC in the remaining empty slot.
Step 6: Connect FC and Power Cables
1 Connect the front-end fiber-optic cables. Front-end fiber-optic cable connections depend on the type of connectors used by the controller and the type of HBA to which the controller is connected. The Virtual Array Products use integrated LC (small form factor) connectors. They support HBAs with either SC (large form factor) or LC connectors. See Figure 40 through Figure 45. 2 Connect power cords to the power receptacle on the power supply/fan module(s). 3 Attach the other end of each power cord to a preinstalled PDU/PDRU. Choose outlets according to the following guidelines: Redundancy. To extend the redundancy of the product, attach each cord to a different PDU. This is represented in Figure 46 and Figure 47. Reliability. To avoid cascading faults for a group of disk systems that are plugged into the same PDU, distribute redundant power cords to as many different combinations of PDUs as possible. See Figure 46 and Figure 47. Cascading faults occur when a backup PDU is overloaded with power surges after the primary PDU fails. Serviceability. Choose PDU locations that prevent power cords from interfering with the removal and replacement of serviceable components. Also leave a 6-inch service loop to allow for the rotation of PDRUs. The letters in Figures 46 and 47 represent independent PDUs or PDU banks. The absence of duplicate letters in individual disk systems indicates the products are using redundant PDUs. The minimal number of duplicate letter pairs indicates the disk systems are protected against cascading faults.
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.

In the above tables, columns 0-6 correspond to possible switch settings. Rows 115 indicate the disk slot positions. SES refers the address reserved for the enclosure controller. The intersection of a row and a column contains the loop ID the device will take. The loop ID is translated to a Fibre Channel address (ALPA) by firmware according to the table in the FC-AL2 standard. Enclosure IDs (0 through 6) are set with a dial on the LCC. This setting determines the FC-AL IDs of the disks and LCCs in the disk system. See Table 8 and Table 10 for the FC-AL IDs and corresponding hardware paths for each slot and LCC based on the Enclosure ID. Caution The Enclosure IDs on both LCCs in the same disk system must be identical.
For redundancy, each LCC is connected to a different Fibre Channel loop (that is, a different 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 Users Guide, which is included in Adobe Acrobat format on the IPR Support Media. You can download a copy of Acrobat Reader without charge from http://www.adobe.com/prodindex/acrobat/readstep.html.

110 Removal and Replacement

Disk Module

Add or replace disks to increase storage capacity or eliminate faults. (See chapter 4 for troubleshooting procedures.) Disks must be Fibre Channel (FC) 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.

2 Pull the disk out of the slot using the extraction handle. Support the disk module with your other hand around the enclosed side. See Figure 57. Note Removing disk modules and fillers from right to left improves access to successive disk modules.
Removal and Replacement 115

Caution Caution

Replace the disk module or filler immediately (see next step). 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 57). (Fillers are not in ESD bags.) 4 Press the cam latch toward the end of the extraction handle to loosen the extraction handle. When you are installing a disk module filler, align the disk filler guides with the chassis rails and insert the filler. Push the filler in until it stops. When it is fully inserted, it will be flush with the rest of the disk modules/disk module fillers. 5 Slide the disk module, capacity label up, into the empty slot. 6 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 LEDs. It should be on while the disk spins up and then turn off. The LED will blink
116 Removal and Replacement
with I/O activity to the disk. If you observe different results, refer to chapter 4, Troubleshooting, for probable causes and solutions. 7 Run IOSCAN on the host and verify that the replacement disk module is claimed. 8 Restore file systems and data as needed (see Preparation on page 111).
Replace an LCC when troubleshooting shows that the card is faulty (see Isolating Causes in chapter 4). There is no need to turn off the disk system to remove and replace an LCC. However, the host must be notified that all disks on the affected loop will be unavailable for I/O. Refer to Preparation on page 111. Caution Touching the LCC pins can cause high energy discharge and permanently damage the LCC.
Caution Do not remove a LCC from an operating product until you have the replacement LCC and are ready to install it. An empty slot will cause uneven cooling and eventual overheating.
1 Remove the cables and/or terminators from the failed LCC. 2 Loosen the locking thumbscrew (A in Figure 58) until it clears the LCC bulkhead. The screw stays in the ejector handle.

120 Removal and Replacement
5 Slide the replacement power supply into the empty slot (D in Figure 60). 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). It is recommended that you use a screwdriver to ensure proper seating. 8 Plug the power cord into the power supply and electrical source. 9 Monitor the power supply LED. It should turn green. If the LED is dark or stays amber, see Chapter 4, Troubleshooting.
Removal and Replacement 121

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. Twenty four inches of vertical space is required in the rack if the midplane or power switch assembly are to be replaced without removing the disk system from the rack. The disk system will be turned off in this procedure. 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.
1 Determine the file systems that will be inaccessible for I/O operations while the disk system is turned off, and perform necessary system administration. (See the HP-UX guide, How HP-UX Works: Concepts for the System Administrator.) 2 Push and release the power button to turn off the disk system. 3 Remove the disk modules from the chassis and set them aside on an antistatic surface. Label the disk modules so they can be reinstalled in the same disk slots. 4 Remove the power supply/fan modules and set them aside on an anti-static surface. 5 Remove screws from the mounting ears (see Figure 61). 6 Disconnect power and Fibre Channel cables from the back of the disk system. WARNING Product is heavy (~54 lbs. without disks). If you choose to remove the disk system from the rack, use two people or a lift device.
