Installing A7173A Adapter Hardware
13
Installing A7173A Adapter Hardware
Before 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.
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.
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.....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. HP system documentation can be accessed at: http://www.docs.hp.com
NOTE HP recommends installing the A7173A adapter in a PCI-X, 133 MHz, 64 bit, 4x (“Twin Turbo”
or “Dual Rope”) slot. The A7173A adapter can be installed in any PCI or PCI-X slot, but
performance will be maximized when it is installed in a 133 MHz, 64 bit, 4x (“Twin Turbo” or
“Dual Rope”) PCI-X slot.

Online Installation
14
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) allows PCI host bus adapters to be added, or replaced, 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.
OLAR or OL* may not be supported on the system you plan to install an A7173A adapter in. See the HP-UX
A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter Support Matrix located at
http://www.docs.hp.com, to confirm if the OLAR or OL* feature is supported.
NOTE For detailed instructions on using OLAR on HP-UX 11i v1, see Chapter 2 of Configuring
HP-UX for Peripherals, which can be accessed at http://www.docs.hp.com
For detailed instructions on using OL* on HP-UX 11i v2 and later HP-UX releases, see the
Interface Card OL* Support Guide, and the Interface Card OL* Support Matrix, which can be
accessed at http://www.docs.hp.com
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.
WARNING 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 the HP A7173A PCI-X Dual Channel Ultra320 SCSI Host
Bus Adapter Support Guide for more information
Connecting SCSI Peripheral Devices
Make all SCSI bus connections to the A7173A adapter with shielded, 68-pin cables (multimode, LVD or SE).
The connectors on the cables are always keyed for proper mating.
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.

Chapter 2
HP-UX Installation: HP A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter
Connecting SCSI Peripheral Devices
15
NOTE Each SCSI channel on the A7173A adapter has an internal HD (high density) SCSI connector
for connecting internal SCSI devices and an external VHDCI (very high density cable
interconnect) SCSI connector for connecting external SCSI devices. HP does not support
connecting SCSI devices to both the internal and external SCSI connectors on the same SCSI
channel.
IMPORTANT If you connect LVD SCSI devices and SE SCSI devices to the same SCSI bus, the data transfer
rate will be limited to a maximum of 40 MB/s (Ultra SCSI), which is the maximum for SE
SCSI.
To view a list of supported peripheral devices see the HP A7173A PCI-X Dual Channel Ultra320 SCSI Host
Bus Adapter Support Matrix located at http://www.docs.hp.com.
Connecting Internal Devices
The A7173A adapter has two internal 68 pin HD connectors, one for each SCSI channel. Connection of
internal SCSI devices will be performed at the factory for HP systems that support internal SCSI devices. If
an internal SCSI device has been installed on one of the A7173A adapter’s SCSI channels, HP does not
support connection of an external SCSI device to that same SCSI 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:
Step 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.
Step 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.
Step 3. If you need to connect more than one external SCSI device to the adapter, “daisy chain” them
together with shielded external SCSI cables.

SCSI Parameter Settings
16
SCSI Parameter Settings
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)
IMPORTANT If the A7173A adapter is new, but it is being installed to replace another SCSI adapter, the mpt
driver will continue to use the SCSI parameter settings that are already configured on the slot.
If the A7173A adapter has been previously installed in a different slot or system, the SCSI
parameter settings will not migrate to the new slot or system.
It is strongly recommended that the SCSI parameter settings be confirmed, and changed if
necessary.
WARNING HP DS2100, DS2110, and DS2300 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 PA RISC systems) or EFI (on Itanium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.
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 Step 2 in the “Verifying the Installation” section of this
Installation Guide for details.
The SCSI parameters for A7173A adapters installed in PA-RISC based systems can be confirmed or changed
offline using the “SCSI” command, which can be accessed from the Boot Console Handler (BCH) menus, see
the HP A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter Support Guide for details.
The SCSI parameters for A7173A adapters installed in Itaniumbased systems can be confirmed or changed
offline using the Extended Firmware Interface (EFI), see the HP A7173A PCI-X Dual Channel Ultra320
SCSI Host Bus Adapter Support Guide for details.

In this example, two A7173A adapters are installed on the system. The fourth and fifth columns in
the ioscan output indicate that the adapters have been claimed by the mpt driver. Notice the
hardware path shown in the second column. The A7173A adapter supports two PCI devices or
functions (one per channel). Two lines are listed for each A7173A adapter, —one for channel A
(denoted by a 0as the last digit in the hardware path), and one for channel B (denoted by a 1as the
last digit in the hardware path). The device file for each channel of each installed adapter is in the
second line of the ioscan output, for example: /dev/mpt6 or /dev/mpt7.
Step 2. For more detailed information on installed A7173A adapter(s), including the SCSI parameter
settings as well as verification of devices that have been connected to the A7173A adapter(s), issue
the mptconfig <dev file> command for each channel of each A7173A adapter. Use the device
files displayed in the ioscan -fnkd mpt output.

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, issue
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.
Refer to 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 the HP A7173A PCI-X Dual Channel Ultra320
SCSI Host Bus Adapter Support Guide for details on setting SCSI IDs in a multi-initiator configuration.
