System Firmware

The firmware on HP 9000 systems is known as Processor Dependent Code (PDC). On HP Integrity® systems, the system firmware is based on the Extensible Firmware Interface (EFI) specifications. There is also an EFI driver component of the A7173A adapter firmware for Integrity®

systems.

Processor Dependent Code (PDC) on HP 9000 Systems

PDC is the system firmware on HP 9000 systems. To determine the correct PDC for PA-RISC based systems,. see the HP Ultra320 SCSI Host Bus Adapter Support Matrix, at:

http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters

The Boot Console Handler (BCH) menus are used offline to confirm the PDC version that is installed on a PA-RISC based system. See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.

If you do not have the correct PDC version installed on your system, contact your HP representative for details on obtaining and installing the correct PDC version.

Extensible Firmware Interface (EFI) on HP Integrity Systems

The system firmware on HP Integrity® systems is based on the Extensible Firmware Interface (EFI) specifications. An EFI utility can be used offline to verify the system firmware version that

is installed on HP Integrity® systems. See, “Using the EFI Utility on HP Integrity Systems”

(page 32), for details.

See the HP Ultra320 SCSI Host Bus Adapter Support Matrix on http://docs.hp.com to determine the minimum system firmware version that is needed to usethe A7173A adapteron your system.

System Firmware 15

Installing A7173A Adapter Hardware

This section contains information about installing the A7173A adapter hardware in a supported HP-UX system.

WARNING! The installation procedures in this section require opening the computer cabinet, which might expose you to high-energy (high-amperage) circuits and sharp edges on the equipment chassis. Be sure to remove all rings, watches, and other jewelry before opening the cabinet.

Before beginning installation, and without removing the adapter from its antistatic bag, inspect the adapter for any signs of obvious damage, such as chipped or loose components. Contact HP if the adapter is damaged.

CAUTION: The A7173A adapter contains electronic components that can easily be damaged by small amounts of static electricity. To avoid damage, follow these guidelines:

• Store the adapter in its antistatic plastic bag until you are ready to install it.

• Work in a static-free area, if possible.

• Handle the adapter by the edges only. Do not touch electronic components or electrical traces.

• If you must lay the adapter down, place it on a non-conductive mat or surface.

• Use the Electrostatic Discharge (ESD) kit that is provided with the adapter. Follow the instructions included with the kit.

• Use a suitable ground; for example, an exposed metal surface on the system chassis can serve as a ground.

Offline Installation

Install the A7173A adapter in any supported HP-UX system according to the offline host bus adapter installation procedure for that system. For more information about installation procedures, see the HP system documentation at:

http://docs.hp.com/en/hw.html

NOTE: The A7173A adapter can be installed in any PCI or PCI-X slot, but for best performance, HP recommends installing the adapter in a PCI-X, 133 MHz, 64 bit, 4x (“Twin Turbo” or “Dual Rope”) slot. For more information on slot specifications, see the system documentation; or, for entry-class servers, see the I/O Slot Matrix – Entry Class Integrity Servers, at:

http://docs.hp.com/en/hw.html#General%20Guides

After installing the A7173A adapter, go to “Connecting SCSI Peripheral Devices” (page 17).

Online Installation

The Online Addition and Replacement feature (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i v2 and later HP-UX releases) enables you to add or replace PCI host bus adapters without shutting down and rebooting the system, and without adversely affecting other system components. The system hardware uses slot-specific power control, combined with HP-UX operating system support, to enable these features.

16 Installing the A7173A Adapter

For more information on OLAR or OL*, see the following documents:

• To determine whether OLAR or OL* is supported on your system, see the HP Ultra320 SCSI Host Bus Adapter Support Matrix:

http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters

• For detailed instructions on using OLAR on HP-UX 11i v1, see Configuring HP-UX for Peripherals:

http://docs.hp.com/en/oshpux11i.html#System%20Administration

• For detailed instructions on using OL* on HP-UX 11i v2, see the Interface Card OL* Support Guide:

http://docs.hp.com/en/oshpux11iv2.html#System%20Administration

• For detailed instructions on using OL* on HP-UX 11i v3, see the Interface Card OL* Support Guide:

http://docs.hp.com/en/oshpux11iv3.html#System%20Administration

IMPORTANT: Superdome systems are not intended for access by users. HP recommends that Superdome systems only be opened by a qualified HP engineer. Failure to observe this requirement can invalidate any support agreement or warranty to which the system owner might otherwise be entitled.

IMPORTANT: If you use OLAR or OL* to add or replace an A7173A adapter, the SCSI ID will be set at 7 by default. If the SCSI ID for an add-in or replacement adapter needs to be set at some value other than 7, the mptconfig command can be used to set the SCSI ID after the A7173A adapter is inserted into the slot and powered on, but before the SCSI cable(s) are connected. See

“About SCSI IDs” (page 24) and “Using mptconfig for Online Configuration” (page 40), for

more information.

Connecting SCSI Peripheral Devices

The A7173A adapter is capable of communicating with Low Voltage Differential (LVD) or Single Ended (SE) SCSI devices. LVD allows up to 12m cable lengths with multiple SCSI devices, or 25m point-to-point connections.

Important Rules For Connecting SCSI Devices

When you connect SCSI devices to an A7173A or AB290A Host Bus Adapter, the following rules apply:

• All of the devices connected to each port must be of the same type; for example, you cannot mix hard disks and removable-media devices on the same port.

• All of the removable-media devices (such as a tape drive, DVD, or CD-ROM) on a SCSI port must be of the same type and speed. For example, you can connect two or more 320 MB/S tape drives to a port, but you cannot mix tape drives of different speeds on the same port.

• Each SCSI channel on the A7173A adapter has an internal HD (high density) SCSI connector and an external VHDCI (very high density cable interconnect) SCSI connector. Do not connect SCSI devices to both the internal and external SCSI connectors on the same channel.

• If you connect devices with different data transfer rates to the same SCSI channel, the speed of that channel will be limited to the maximum transfer rate of the slowest device. For example, if you connect both LVD SCSI devices and SE SCSI devices to the same SCSI channel, the data transfer rate for that channel will be limited to 40 MB/s, which is the maximum rate for SE SCSI.

To view a list of supported peripheral devices see the HP Ultra320 SCSI Host Bus Adapter Support Matrix:

Connecting SCSI Peripheral Devices 17

http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters

Identifying Compatible SCSI Cables

Make all SCSI bus connections to the A7173A adapter with shielded, 68-pin cables (multimode, LVD or SE). The connectors on the cables are keyed for proper mating.

Figure 2-1 Identifying SCSI Cable Connectors

68-pin ExternalHD (high density) SCSI cable connector

External Offset VHDCI (very high density cable interconnect) SCSI cable connector

Connecting Internal Devices

The A7173A adapter has two internal 68 pin HD connectors, one for each SCSI channel. If you purchased your A7173A adapter as a factory-integrated controller (ordered on product option 0D1), any internal SCSI devices will be connected at the factory. If an internal SCSI device has been installed on one of the A7173A adapter’s SCSI channels, do not connect any devices to the external port for that channel.

Connecting External Devices

The A7173A adapter has two external 68 pin VHDCI connectors, one for each SCSI channel. External SCSI devices, may have 68 pin HD or VHDCI connectors. No SCSI cables are shipped with the A7173A adapter.

NOTE: Auto termination is factory enabled on the A7173A adapter. External terminators can be ordered from HP, if necessary (order SCSI LVD/SE terminator: HP product number C2370A).

To connect external SCSI devices to the A7173A adapter:

1. Plug the 68-pin VHDCI connector on one end of a SCSI cable into an external connector on the A7173A adapter. Make sure the external connector you attach the SCSI cable to corresponds to the channel you want to connect the external device to.

2. Plug the 68-pin HD or VHDCI connector on the other end of the cable into the SCSI connector on the external SCSI device.

3. If you need to connect more than one external SCSI device to the adapter, “daisy chain” them together with shielded external SCSI cables.

When you have finished connecting the external devices, go to, “Setting the SCSI Parameters”

(page 23).

Confirming the A7173A Adapter Firmware Version

To verify the firmware version currently running on an online A7173A adapter, use the mptutil <device_file> command. For more information about online and offline firmware verification

or updates, see “Verify or Update A7173A Adapter Firmware On HP 9000 Systems” (page 46), or “Verify or Update A7173A Adapter Firmware on HP Integrity Systems” (page 46).

To determine the device files for the A7173A adapters in your system, use the ioscan -fnkd

mpt command:

# ioscan -fnkd mpt

The device file for each channel of each A7173A adapter is in the second line of the ioscan output for each channel. In the sample output, the device files are /dev/mpt6, /dev/mpt7, /dev/mpt8, and /dev/mpt9.

When you have determined the device files, use the mptutil <device_file> command to determine thefirmware version currently running (in ROM) on the A7173A adapter. Both channels on each adapter share the same firmware, so it is only necessary to query one channel to determine the current firmware version. For example:

# mptutil /dev/mpt8

NOTE: The In Use Device column only displays on systems running HP-UX 11i v3.

NOTE: When the system boots after installation, the insf command creates the proper device

files for the “ctl” interfaces (which would include the A7173A adapter) as well as the SCSI devices attached to the A7173A adapter. Sometimes, however, the insf command does not create all of the device files that are needed. For example, this happens when you attach SCSI disks to the adapter after the system boots, but the adapter is already installed in the system.

If you see a SCSI device listed in the ioscan output, but there is no device file in the second line of the ioscsan output for that device, the device file is missing. To solve this problem, use the insf -e command, which will create all of the device files.

For more information about the ioscan command, see the ioscan(1M) man page.

For more information about the insf command, see the insf(1M) man page.

See your system documentation for information about verifying system operation.

Adding Multi-Initiator Support

The A7173A adapter supports multi-initiator configurations. In a multi-initiator configuration, multiple SCSI host bus adapters are connected to the same SCSI bus. See “About SCSI IDs”

(page 24), for details on setting SCSI IDs in a multi-initiator configuration.

Adding Multi-Initiator Support 21

3 Configuring the A7173A Adapter

This chapter contains the following sections describing configuration of the A7173A adapter:

• “Setting the SCSI Parameters” (page 23)

• “About SCSI IDs” (page 24)

• “About the Maximum Data Transfer Rate” (page 24)

• “About Bus Width” (page 25)

• “About Auto-Termination” (page 26)

• “Configuration Worksheet” (page 27)

• “Setting and Confirming SCSI Parameters Offline” (page 28)

• “Setting and Confirming SCSI Parameters Online” (page 39)

• “Setting SCSI Parameters to Default Values” (page 44)

• “Configuring LUN 0” (page 44)

• “Using the A7173A Adapter as a Boot Device” (page 44)

Setting the SCSI Parameters

The following user configurable SCSI parameters can be set offline or online:

• SCSI ID

• Maximum Data Transfer Rate

• Bus Width

If the A7173A adapter is new and it is installed in a slot that has never been configured for a SCSI adapter, the adapter will be set to the following default settings:

• SCSI ID = 7

• Maximum Data Transfer Rate = MAX (320 MB/s)

• Bus Width = 16 bits (Wide)

Even if these default settings are appropriate for your configuration, HP recommends that you confirm the settings and make changes if necessary.

IMPORTANT: When you replace an A7173A adapter, these conditions determine whether the previous settings will be applied to the replacement adapter:

• If the replacement adapter is new and has never been installed in a system, then the mpt

driver will continue to use the SCSI parameter settings that are already configured for the slot.

• If the replacement adapter was previously installed in a different slot or system, then the SCSI parameter settings will not migrate to the new slot or system.

HP recommends that you confirm the settings and make changes if necessary.

The SCSI parameters for A7173A adapters installed in HP 9000 systems can be confirmed or changed offline using the “SCSI” command, which can be accessed from the Boot Console Handler (BCH) menus, see “Using the BCH Menus on HP 9000 Systems” (page 28) for details.

Setting the SCSI Parameters 23

NOTE: The bus width parameter cannot be set offline on rp24xx and rp54xx systems.

The SCSI parameters for A7173A adapters installed in HP Integrity systems can be confirmed or changed offline using the Extensible Firmware Interface (EFI), see “Using the EFI Utility on

HP Integrity Systems” (page 32).

The SCSI parameters for an A7173A adapter installed in any supported HP-UX system can be confirmed or changed online using the mptconfig command, see “Using mptconfig for Online

Configuration” (page 40).

To restore the default SCSI parameter settings, see “Setting SCSI Parameters to Default Values”

(page 44).

About SCSI IDs

The firmware suggested default for the A7173A adapter SCSI ID is 7.

You must assign a separate SCSI ID (0 through 15 for a 16-bit SCSI bus) to the A7173A adapter and to each SCSI device on the bus. The priority of a device on a SCSI bus is determined by the SCSI ID of the device. The order of SCSI ID priorities (from highest to lowest) is 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, and 8. A device with SCSI ID 7 has the highest priority, and one with SCSI ID 8 has the lowest.

HP recommends the A7173A adapter be assigned a higher priority than the other SCSI devices on the bus. SCSI ID 7 is the preset SCSI ID for the A7173A adapter, giving it the highest priority on the SCSI bus. Set each of the other SCSI devices on the bus to one of the remaining SCSI IDs.

In a multi-initiator HA (High Availability) configuration, multiple SCSI adapters are connected to the same SCSI bus. In a multi-initiator configuration, the SCSI adapter that carries the most traffic must be assigned a SCSI ID of 7 (highest priority). The SCSI ID of each of the remaining SCSI adapters on the bus should be set to the next highest priority remaining SCSI IDs (for example, 6, 5, 4, and so on) with the highest traffic adapters getting the highest priority SCSI IDs.

Setting SCSI IDs Offline

For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set SCSI IDs offline. See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.

For HP Integrity® systems, EFI is used to set SCSI IDs offline. See “Using the EFI Utility on HP

Integrity Systems” (page 32), for details.

Setting SCSI IDs Online

The mptconfig command is used to display and set SCSI IDs online for all supported systems. See “Setting and Confirming SCSI Parameters Online” (page 39), for details.

NOTE: Peripheral device SCSI IDs are typically determined automatically by the storage enclosure, or they may be set manually by a switch on the storage enclosure. See the documentation for each peripheral device to determine how to set its SCSI ID.

IMPORTANT: You must not have duplicate SCSI IDs on a SCSI bus; the system may hang or crash if you have duplicate SCSI IDs on the same bus.

About the Maximum Data Transfer Rate

The firmware suggested default for the A7173A adapter data transfer rate is “MAX” or “NOLIMIT”, which allows a maximum data transfer rate of 320 MB/s. The A7173A can communicate with all LVD or SE devices that have data transfer rates up to 320 MB/s, including the following data transfer rates (synchronous communication over a Wide bus):

24 Configuring the A7173A Adapter

• Fast (20 MB/s)

• Ultra (40 MB/s)

• Ultra2 (80 MB/s)

• Ultra160 (160 MB/s)

• Ultra320 (320 MB/s)

The actual data transfer rate between the A7173A adapter and the other SCSI devices on the bus depends on the maximum data transfer rate that is automatically negotiated for each of the devices on the bus.

For example, if you set the A7173A adapter’s maximum data transfer rate to NOLIMIT (which will be 320 MB/s), and then connect a disk drive that has a maximum data transfer rate of Ultra2 (80 MB/s), the actual transfer rate will automatically be negotiated to a maximum of 80 MB/s.

WARNING! HP DS2100, DS2110, and DS2300 external storage devices are only supported at a maximum SCSI data transfer rate of U160. The SCSI data transfer rate must be limited to U160 (or slower) to avoid potential data integrity issues. The SCSI bus will not automatically adjust to accommodate the DS2100 or the DS2110. The SCSI data transfer rate must be deliberately set to a maximum of U160; offline via the Boot Console Handler (on HP 9000 systems) or EFI (on HP Integrity systems), or online via the mptconfig command. With the DS2300 the SCSI data transfer rate will automatically be negotiated to U160 (or slower), but the negotiation could cause a few SCSI bus resets, which can be avoided by deliberately setting the maximum SCSI data transfer rate to U160.

TIP: Unless you are connecting an HP DS2100, DS2110, or DS2300 external storage device to an A7173A adapter, HP recommends that you always set the A7173A adapter’s maximum data transfer rate to MAX or NOLIMIT (this is the default setting for the A7173A adapter).

Using MAX or NOLIMIT enables the adapter’s maximum data transfer rate of 320 MB/s to be used, unless there are slower devices on the bus that automatically negotiate a slower data transfer rate. Automatic negotiation of the data transfer rate will set the maximum data transfer rate on the SCSI bus to the maximum data transfer rate capability of the slowest SCSI device on the bus.

TIP: If you are trying to debug a communication problem between the A7173A adapter and a specific SCSI device, setting the data transfer rate at a slower speed may enhance diagnostic efforts. See Chapter 5: “Troubleshooting” (page 51), for more information.

Setting the Maximum Data Transfer Rate Offline

For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set the maximum data transfer rate offline. See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.

For HP Integrity® systems, EFI is used to set the maximum data transfer rate offline. See “Using

the EFI Utility on HP Integrity Systems” (page 32), for details.

Setting the Maximum Data Transfer Rate Online

The mptconfig command is used to set the maximum data transfer rate online for all supported systems. See “Using mptconfig for Online Configuration” (page 40), for details.

About Bus Width

The firmware suggested default for the A7173A adapter’s bus width is MAX (the A7173A adapter’s maximum bus width, 16 bits [Wide]). However, either of the following bus widths can be used:

• 8 bits (Narrow)

• 16 bits (Wide)

About Bus Width 25

TIP: HP recommends that you always use the A7173A’s maximum bus width (16 bits), unless you have Narrow (8-bit) devices on the bus and you are experiencing problems with the connection.

Setting the Bus Width Offline

For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set bus width offline. See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.

NOTE: The bus width parameter cannot be set offline on rp24xx and rp54xx systems.

For HP Integrity® systems, EFI is used to set the bus width offline. See “Using the EFI Utility

on HP Integrity Systems” (page 32), for details.

Setting the Bus Width Online

The mptconfig command is used to set the bus width online for all supported systems. See

“Using mptconfig for Online Configuration” (page 40), for details.

About Auto-Termination

The auto-termination feature on the A7173A adapter ensures the SCSI bus will be properly terminated in any supported configuration.

The auto-termination state for both of the SCSI channels on the A7173A adapter are factory set to enable auto termination. HP does not recommend disabling auto termination.

NOTE: All supported configurations require auto termination to be enabled on the A7173A adapter.
