Chapter 110

HPA5150A Adapter Overview

Interface Descriptions

This section provides greater detail about the PCI, SCSI, and Wide Ultra2 SCSI interfaces.

The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O components to a processor and memory subsystem. The PCI functionality for the A5150A is contained within the I/O Processor Chip. The adapter connects directly to the PCI bus and generates timing protocol in compliance with the PCI application.

The PCI interface operates as a 32-bit or 64-bit DMA bus master. The connection is made through the edge connector J1 (see Figure 1-1 on page 9). The signal deﬁnitions and pin numbers conform to the PCI Local Bus Speciﬁcation Revision 2.1 standard. The A5150A conforms to the PCI universal signaling environment for a 5 volt or 3.3 volt PCI bus.

The SCSI Interface

The SCSI functionality for the A5150A is contained within the PCI-SCSI I/O Processor Chip. The adapter connects directly to the two SCSI buses for 16-bit SE or LVD SCSI applications and generates timing and protocol in compliance with the SCSI standard. Each SCSI interface operates at a burst transfer rate of up to 40 MBytes per second for wide single-ended transfers, and up to 80 MBytes per second for wide LVD SCSI transfers.

The two SCSI interfaces on the host bus adapter card operate as 16-bit, synchronous or asynchronous, single-ended or LVD, and support Ultra2 SCSI protocols and 16-bit arbitration. The interface is made through connectors J2 and J5 for channel A and J3 and J4 for channel B. Connectors J2 and J3 are 68-pin, VHDCI right- angle receptacles that protrude through the ISA/EISA bracket.

The adapter supplies SCSI bus TERMPWR (termination power) through a blocking diode and auto-resetting current-limiting device. Each SCSI channel has two LEDs to indicate the terminator’s power (TERMPWR) status. The TERMPWR Good (Channel A or B) LED indicates when the termination power is above 3.0 volts. The TERMPWR Shorted LED

Chapter 1 11

HPA5150A Adapter Overview

Interface Descriptions

indicates when the termination power was subjected to an over current condition causing the self-resetting current limiting device (circuit breaker) to trip.

A 40 MHz oscillator is installed on the A5150A card to provide the clock frequency necessary to support Wide Ultra2 SCSI transfers of up to 80 MBytes per second.

The Wide Ultra2 SCSI Interface

The adapter card has full support for Wide Ultra2 SCSI. This interface is an extension of the SCSI-3 family of standards that expands the bandwidth of the SCSI bus to allow faster synchronous data transfers, up to 80 MBytes per second. Wide Ultra2 SCSI provides a doubling of the data rate over the Ultra2 SCSI interface, increases the possible cable lengths, and also allows a larger number of devices on the cable than Ultra2 SCSI interfaces.

Special SCSI cables are speciﬁed for operation with Wide Ultra and Ultra2 SCSI devices. You must consider the total number of devices and the length of your SCSI bus when setting up your system. The section “Connecting the SCSI Peripherals” on page 27 provides a more detailed explanation of SCSI bus connections.

Chapter 216

Installing the A5150A Adapter

Preparing for Installation

Installing the host bus adapter requires disassembly of some server components. Before beginning installation, refer to the system server manual for detailed instructions on installing host bus adapters in the PCI slots.

You will need the following things:

✓ One HP A5150A SCSI adapter. ✓ One grounding (ESD) strap. ✓ Any other tools needed for installing components in the HP 9000

system (for example, screwdrivers); see the system’s documentation.

Chapter 2 17

Installing the A5150A Adapter

Handling the A5150A Adapter

The host bus adapter is packaged with an ESD kit, which contains materials to prevent damage from static electricity during installation.

CAUTION The adapter is highly susceptible to damage by electrostatic discharge

during installation and routine maintenance procedures. Do not handle circuit boards without wearing a wrist strap fastened to a good earth ground or to the system chassis.

While you are installing the A5150A adapter, please follow these precautions:

✓ Keep the adapter in its shielded antistatic bag until you are ready to

install it.

✓ Use a wrist strap or other ESD protection. Wrap the strap around

your wrist and attach the copper end to a metal portion of the computer frame.

✓ Avoid working in carpeted areas. ✓ Gently place the adapter, printed circuit board (PCB) side down, on

an antistatic work surface pad.

✓ Hold the adapter only by its sides or cover plate. Do not touch any

components on the printed circuit board assembly (PCBA).

✓ Do not use any test equipment to check the components on the PCB. ✓ Do not bump, jar, or drop the adapter. Do not place other objects on

top of the adapter.

✓ Transport the adapter in its shielded bag in an appropriate shipping

container. Do not put other materials in the bag with the adapter.

Chapter 218

Installing the A5150A Adapter

Looking at Adapter Installation

Installation can be performed in one of two ways:

• Use the OLAR (On Line Add/Replace) capability (HP-UX 11i). Refer to “Install Using OLAR (HP-UX 11i)” on page 20.

• Power down the system and then add or replace the HBA. Refer to “Install/Replace With System Powered Down” on page 25.

The method you choose will depend on your situation, the card you are installing, and your requirements.

Before You Start

For safe and proper installation, do the following: Look through the task list below to get an overall idea of the steps to

perform.

1. Determine whether or not you can use the OLA/R (On Line Addition [and] Replacement) method to install the HBA (see “Install Using OLAR (HP-UX 11i)” on page 20).

2. Remove the SPU/system cabinet cover on the system to access the PCI slots. Refer to the system server manual for accessing PCI slots.

3. Insert the host bus adapter.

4. Connect the SCSI peripherals.

5. Terminate the external SCSI bus.

6. Set the peripheral SCSI IDs.

7. Make any conﬁguration changes.

8. Replace the SPU/system cabinet cover.

The SCSI host bus adapter acts on the server’s behalf as the host to the suite of SCSI peripherals. Each chain of SCSI peripheral devices and their host bus adapter work together and are referred to as a SCSI bus.

Each channel on your SCSI host bus adapter can act as host for up to 15 peripheral devices (depending on the SCSI bus speed), not including the adapter itself.

Chapter 2 19

Installing the A5150A Adapter

Looking at Adapter Installation

NOTE The host bus adapter card is supported on the HP N4000 N-class system.

Refer to the Hewlett-Packard eproducts web site (http://www.eproducts.hp.com) to disassemble the system, install the adapter in an available PCI slot, and reassemble the system.

Install Using OLAR (HP-UX 11i)

The letters O, L, A and R stand for On Line Addition [and] Replacement. This refers to the ability of a PCI I/O card to be installed (replaced or added) in an HP-UX computer system designed to support this feature without the need for completely shutting down, then re-booting the system or adversely affecting other system components. The system hardware uses the per-slot power control combined with operating system support in HP-UX 11i to enable this feature.

IMPORTANT Certain “Classes” of hardware are not intended for access by users. At

this time this includes V-Class and SuperDome systems. HP recommends that these systems only be opened by a qualiﬁed HP Engineer. Failure to observe this requirement can invalidate any support agreement or warranty to which the owner might otherwise be entitled.

Important Terms and Concepts

The addition or replacement of an OLAR-compatible card may be done in either one of two ways:

1. Using the SAM utility.

2. Issuing command-line commands using rad.

For detailed information about the use of either of these two procedures, please refer to the following document:

for the target card slot also suspends individual drivers for the multiple hardware paths on that card).

During a card replacement operation, SAM performs a Critical Resource Analysis, which checks all ports on the target card for critical resources that would be temporarily unavailable while the card is shut down.

Installing the A5150A Adapter

Looking at Adapter Installation

Planning and Preparation

SAM will, generally, prevent you from performing OLAR procedures that would adversely affect other areas of the server. Refer to Conﬁguring HP-UX For Peripherals, HP Part Number B2355-90698 for detailed information.

Critical Resources Because power to the slot must be off when the old card is removed and the new card is inserted, the effects of shutting down the card’s functions must be carefully considered.

This is particularly important if there is no on-line failover or backup card to pick up those functions. For example:

• Which mass storage devices will be temporarily disconnected when the card is shut down?

• Will a critical networking connection be lost?

A critical resource is one that would cause a system crash or prevent the operation from successfully completing if the resource were temporarily suspended or disconnected. For example, if the SCSI adapter to be replaced connects to the unmirrored root disk or swap space, the system will crash when the card is shut down.

During an OLAR procedure, it is essential to check the targeted card for critical resources, as well as the effects of existing disk mirrors and other situations where a card’s functions can be taken over by another card that will not be affected.

Fortunately SAM performs a thorough critical resource analysis automatically, and presents options to you based on its ﬁndings. If you determine that critical resources will be affected by the procedure, you should replace the card when the server is off-line. If you must take action immediately, you can use rad to attempt an on-line addition of a backup card and deletion of the target card.

Card Compatibility On-Line Addition (OLA). When on-line adding an interface card, the

ﬁrst issue that must be resolved is whether the new card is compatible with the system. Each PCI slot provides a set amount of power. The replacement card cannot require more power than is available.

The card must also operate at the slot’s bus frequency. A PCI card must run at any frequency lower than its maximum capability; however, a

Chapter 222

Installing the A5150A Adapter

Looking at Adapter Installation

card that operated at a maximum of 33 MHz would not work on a bus running at 66 MHz. rad provides information about the bus frequency and power available at a slot, as well as other slot-related data.

On-Line Replacement (OLR) When on-line replacing an interface card, the replacement card must be identical to the card being replaced or at least be able to operate using the same driver as the replaced card. This is referred to as like-for-like replacement and should be adhered to because using a similar but not identical card may cause unpredictable results. For example, a newer version of the target card which is identical in terms of hardware may contain an updated ﬁrmware version that could potentially conﬂict with the current driver.

The PCI speciﬁcation allows a single physical card to contain more than one port. A single-port SCSI bus adapter can not be replaced by a dual-port adapter, even if the additional port(s) on the card are identical to the original SCSI bus adapter.

When the replacement card is added to the system, the appropriate driver for that card must be conﬁgured in the kernel before beginning the operation. SAM ensures the correct driver is present. (In most cases, the replacement card will be the same type as a card already in the system, and this requirement will be automatically met.) If you have any question about the driver’s presence, or if you are not certain that the replacement card is identical to the existing card, you can use ioscan together with rad to investigate.

• If the necessary driver is not present and the driver is a dynamically loadable kernel module (DLKM), you can load it manually. Refer to the section “Dynamically Loadable Kernel Modules” in Chapter 2 of the document: Conﬁguring HP-UX For Peripherals, HP Part Number B2355-90698 for more information.

• If the driver is static and not conﬁgured in the kernel, then the card cannot be On-line Added. The card could be physically inserted on-line, but no driver would claim it.
