Product Description
This chapter gives a functional and physical overview of the KZPCM PCI-to-Dual
Channel Ultra SCSI and 10/100MB Ethernet Host Adapter (‘the KZPCM Host Adapt er’ or
‘the Host Adapter’) and provides specifications for significant characteristics.
1.1 Functional Description
The KZPCM Host Adapter (Figure 1-1) provides an interface between a host
computer PCI bus and both internal and external SCSI devices. In addition, the
Host Adapter includes support for 10/100 Base-T Ethernet communications,
which can be carried on concurrently with I/O operations.
Figure 1-1 KZPCM Host Adapter
HR-1027
EK–KZPCM–UG. B01 1–1
KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter
The KZPCM Host Adapter is a leading edge host adapter that supports bootable
devices and provides a powerful multi-tasking interface. Each channel on the
Host Adapter forms a separate SCSI bus together with its attached devices. The
SCSI buses can be connected to disk drives, CD-ROM drives, tape drives, and
other SCSI devices. More than one Host Adapter can be installed in the same
host computer.
The SCSI processor negotiates with each device on the SCSI bus to establish the
data transfer rate between the host adapter and the device. It also automates
SCSI command processing and significantly reduces the number of interrupts and
command overhead.
The Host Adapter supports multi-threaded I/O operations, thereby allowing
simultaneous operations on multiple SCSI targets or Logical Units (LUNs). In
systems with multiple targets, the Disconnect/Reconnect feature optimizes SCSI
bus usage. In systems that support fragmented memory buffers, the
Scatter/Gather feature provides high performance.
1.2 Physical Description
The KZPCM Host Adapter components are mounted on a 4 ¼ inch by 8 ¾ inch
PCB that is inserted in a PCI expansion slot in the host computer motherboard.
The PCB has separate connectors for each of the two available Ultra SCSI
channels. Channel A has two 68-pin connectors for Ultra-wide SCSI operation,
one for external devices and one for internal devices, and one 50-pin connector
for Ultra-narrow internal SCSI devices; channel B has two 68-pin connectors for
Ultra-wide SCSI operation, one for external devices and one for internal devices.
External connection to an Ethernet network is made through a shielded RJ45
connector for 8-conductor twisted pair cable.
Channel A and Channel B are equipped with both internal and external ultraSCSI wide (supports 15 devices) connectors; in addition, Channel A is equipped
with an internal ultra-narrow 50-pin connector. However, a DIGITAL
StorageWorks shelf with ultra-wide connections can run ultra-wide and ultranarrow drives concurrently.
The external bulkhead of the Host Adapter contains LED indicators that monitor
Ethernet activity.

2.2.3 Back up Your System
Follow your normal procedures to back up your system before installing the
KZPCM Host Adapter.
2.3 Terminating the SCSI Buses
The KZPCM Host Adapter has dual-SCSI channel capability, and each bus must
be terminated at both ends of the bus. The Host Adapter can be located at the
beginning of the bus or in the middle of the bus; consequently, termination on
the Host Adapter itself can be enabled or disabled. Furthermore, if both the
wide- and narrow-SCSI connectors on the A-channel are used, the narrow-SCSI
termination on the Host Adapter must be disabled.
Use the termination switchpack, SW1, on the Host Adapter PCB (Figure 2-1) to
enable or disable terminations on the PCB. Tables 2-1 and 2-2 show how the
switchpack switches should be set according to how devices are connected to
Channel A and Channel B connectors, respectively, of the Host Adapter.

2.4 Setting SCSI Device IDs
Each device and host adapter on the SCSI bus must have a unique SCSI ID. It is
recommended that the Host Adapter be left at its default ID of 7. If it is
necessary to change the Host Adapter ID, refer to Table 3-1,
Quick Reference Chart
.
On systems that do not use the on-board BIOS Configuration utility refer to the
software descriptions for instructions on changing SCSI IDs. All Intel-based
systems use the on-board BIOS utilities; Alpha-based systems use AlphaBIOS
for Windows NT and SRM console for DIGITAL UNIX and DIGITAL
OpenVMS.
The Host Adapter supports SCSI Configured AutoMatically (SCAM) protocol,
which assigns SCSI IDs automatically and resolves SCSI ID conflicts. Devices
that support the SCAM protocol do not need to be assigned a SCSI ID manually.
Because SCAM is a recent addition to the SCSI specification, many devices do
not yet support the protocol and their IDs must be configured manually (refer to
the device documentation). SCAM support is enabled by default; refer to the
BIOS configuration utility instructions if you need to disable SCAM protocol.
Parameter Settings
NOTE
On a 16-bit SCSI bus each device must have a
unique SCSI ID from 0 to 15. Since the Host
Adapter default ID is 7, all other devices on the
bus should be gi ven IDs from 0 to 6 and 8 to 15.
Refer to the dev ice doc umentati on for i nst ruct ions
on setting the SCSI ID for that device (not all
operating systems currently support SCSI IDs
above 7).

Chapter 2. Installing the KZPCM Host Adapter
2.5 Installing the Host Adapter
Install the Host Adapter module using the following procedures. Take
precautions to protect the module from static discharge.
CAUTION
To protect the board from s tatic dis charge, wear
an electr ostatic dis charge (ESD) wris t strap. If a
wrist strap is unavailable, ground yourself by
touching a bare metal surface on the computer
chassis before you open the case.
2.5.1 Inserting the Host Adapter in a Chassis Slot
Do the following steps to insert the Host Adapter module in the chassis slot:
1. Turn off the power to the computer system and attached peripherals, and
disconnect the ac power cords.
2. Remove the computer cover (refer to your computer manual for
instructions).
3. Locate an available PCI bus slot. PCI slots are shorter than ISA and EISA
slots and are normally colored white. (Refer to your computer manual to
determine the location of the PCI bus slot in your system.)
Unscrew and remove the outside slot cover. The slot cover is the metal strip
that covers the opening in the rear of the computer chassis and where the
external connector on the adapter fits (save the screw.)
4. Carefully remove the KZPCM Host Adapter from its protective anti-static
bag and insert it into the slot. Press down on the top of the card until it seats
firmly. See Figure 2–2.
NOTE
PCI cards are des igned with thei r components on
the opposite side of non-PCI cards
5. Secure the KZPCM host adapter with the screw previously used to secure the
slot cover.
6. Do not install the computer cover or reconnect power until all the SCSI
devices are connected.

4. To connect three or more internal SCSI devices to the SCSI bus, the ribbon
cable must have enough connectors to accommodate all the devices. Plug the
connectors into the SCSI devices maintaining the pin-1 orientation.
5. If you are using both internal connectors on the host adapter, proceed in the
same fashion as above for the other cable.
2.5.3 Connecting External SCSI Devices
The preferred cabling method is a point-to-point cable connection from the
KZPCM Host Adapter to the BA356. Up to fifteen wide SCSI devices can be
supported externally to the Host Adapter through carefully cabled topologies.
See the Ultra SCSI Configuration Guide for more details.
The KZPCM Host Adapter does not support daisy-chained configurations with
the Host Adapter in the middle of the SCSI bus attached by the external
connector.
The external connector on the module is a 68-pin VHDCI connector. The
external connector is keyed so that it can be plugged in only one way making the
pin-1 orientation automatically correct.
Follow these steps to connect an external SCSI device housed within a BA356
shelf:
1. Attach one end of the cable to the KZPCM Host Adapter via the bulkhead
connector (Figure 2–7).

Windows NT Installation
This chapter describes briefly the SYMC8XX.SYS miniport driver that enables the
KZPCM Host Adapter to work with the Windows NT operating system, version 4.0, and
tells you how to install the driver in the host computer.
4.1 SYMC8XX.SYS Miniport Driver Description
The Windows NT operating system, version 4.0, is designed to run on processors
using Intel and RISC technology. The operating system provides a graphical user
interface environment, without DOS, incorporating many high-level features. I/O
requests in Windows NT 4.0 are handled by an I/O manager. To address a SCSI
peripheral the I/O manager goes through the appropriate drivers. Class drivers for
hard disk, optical, CD-ROM, printer, and scanner peripherals are provided in
Windows NT 4.0. Other class drivers, provided by peripheral manufacturers, are
added to support new devices. Tape device support is built into the operating
system itself and does not require a class driver. The SYMC8XX.SYS miniport
driver is added to complete the path from the Windows NT operating system to
the KZPCM Host Adapter.
The driver is designed to meet Microsoft specifications for miniport drivers.
SCSI commands are passed directly from a Windows application to the SCSI
devices by using the SCSI pass-through facility. This facility allows applications
to control and access SCSI devices directly by filling in a data structure and
calling into the port driver.
The SYMC8XX.SYS driver supports Fast 20/Ultra SCSI protocol, providing
twice the raw data transfer rate of Fast SCSI for disk drives and host adapters
that support Fast 20/Ultra SCSI. However, Fast 20/Ultra SCSI has more stringent
SCSI bus cabling requirements than Fast SCSI. The SYMC8XX.SYS driver
supports:

4.2 Installing the SYMC8XX.SYS Miniport Driver
You can install the driver in a new system or in an existing system using the
method described here.
NOTE
Refer to t he fi le READ_ME. TXT on t he ins t all ati on
disk for additional information about this
procedure.
This procedure installs the SYMC8XX.SYS driver in a Windows NT Alpha
system. Use this procedure when installing NT on an Alpha system with an
unused SCSI driver or on one where a driver already exists. NT adds the driver to
the registry and copies the driver to the appropriate directories. The KZPCM
Host Adapter using the Symbios Logic 875 Ultra SCSI controller supports
installation of the system disk provided the base system has support in the
AlphaBIOS console for the 875 controller chip.
Because the drivers on the NT CD do not support the KZPCM Host Adapter by
default, manual intervention of the installation process is required. Follow these
steps to install the driver.
1. Boot Windows NT and log on as Administrator.

4.3 Troubleshooting
You might experience a problem while installing the driver. Here are some
problems that can occur, along with suggestions about how to correct them.
4.3.1 No SCSI Devices Are Found During Installation
If this problem occurs, you might be able to correct it by doing one or more of
the following steps.
1. Ensure that you have read and followed the instructions in Section 4.2,
Installing the SYMC8XX.SYS Miniport Driver.
2. Ensure that all devices have power and are terminated properly.
3. Check that no devices have duplicate SCSI IDs (check the device installation
guide for how to set the SCSI IDs on each disk); the Host Adapter defaults
to 7.
EK–KZPCM–UG. B01 4–3
KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter
4. Be certain that your system’s console supports the 53C875 (Alpha firmware
upgrade CD 5.0).
4.3.2 Disk Drive is Recognized as Seven Different Devices When
Only One is Physically Connected to the SCSI Bus.
1. This error is usually caused by older SCSI devices incorrectly indicating to
Windows NT that they support multiple LUNs; contact the device
manufacturer for a possible firmware upgrade.
2. This error can also occur if a disk is at the same SCSI ID as the controller. If
you have not changed the SCSI ID of the Host Adapter from default (7),
make sure there is no other SCSI device at ID 7.
4.3.3 Problems With Ultra Devices Using Ultra Protocol
1. If the system is configured with a SCSI host adapter that supports Ultra
SCSI, an Ultra device is on the SCSI bus, and Fast 20/Ultra support by the
SYMC8XX.SYS driver is enabled, intermittent problems and possible
system crashes can occur if the SCSI bus cable and terminators do not
conform to the Fast 20/Ultra specification.
2. If the system is bootable, disable Fast 20/Ultra support using Control C
BIOS accessible from your Alpha BIOS console.
3. If the system operates properly without Fast 20/Ultra enabled, it is highly
likely that the SCSI bus cable and terminators are not configured correctly
for Fast 20/Ultra.

DIGITAL OpenVMS Installation
This chapter describes briefly the DIGITAL OpenVMS driver that enables the KZPCM
Host Adaper to work with the DIGITAL OpenVMS operating system , and tells you how to
install the driver in the host computer.
5.1 DIGITAL OpenVMS Driver Description
NOTE
The minimum DI GITAL OpenVMS versi on for the
KZPCM Host Adapter is version 7.1-1H1.
The DIGITAL OpenVMS driver enables the use of Ultra SCSI disks to maximize
the PCI-based Alpha system I/O throughput and storage capacity. The driver is
optimized for minimum load on the system processor by use of a loadable
SCRIPT to handle low-level SCSI operations and minimize the number of interrupt requests to the system. In the case of small I/Os, the DIGITAL OpenVMS
driver interrupts the host only once for each I/O, compared with several interrupts per I/O for other SCSI adapters. The Ultra SCSI VMS driver features support for:
Ultra SCSI at speeds up to 40 Mb/sec per channel.
•
Synchronous negotiation (including Fast/Ultra SCSI).
•
Single-interrupt-per-small-I/O technology for maximum I/O throughput with
•
minimum CPU overhead.
Up to 15 disks per channel.
•

prepared floppy disk. This floppy disk contains the driver and the necessary instructions to instruct
Third Party Boot
where to put the drivers and how to map
the new drivers to their respective hardware devices.
Third Party Boot
has the following significant advantages over the hard-coded
mechanism from previous DIGITAL OpenVMS versions:
It allows drivers that are not part of the DIGITAL OpenVMS kit to be loaded
•
onto VMS, and to be configured automatically as though they were kitted with
the operating system.
5–2 EK–KZPCM–UG. B01
Chapter 5. DIGITAL OpenVMS Installation
It allows booting of third party devices.
•
It de-couples device drivers from major DIGITAL OpenVMS releases such
•
that drivers can be added or modified between DIGITAL OpenVMS releases.
DIGITAL has added two files that are relevant to the third party boot mechanism:
s
ys$system:sys$config.dat
and
sys$system:sys$user_config.dat
These files map I/O devices to their respective drivers.
Sys$config.dat
is provided by DIGITAL to support all devices known at the time the operating system
is kitted, and
sys$user_config.dat
is a blank template for adding additional de-
vices. The KZPCM Host Adapter installation procedure modifies
sys$user_config.dat
by appending an entry for DIGITAL products.
Perform these steps to install the driver.
1. Place the DIGITAL OpenVMS, Version V7.1-1H1, CD (DIGITAL part
number QA–MT1AD–H8) in the CD-ROM drive (this example uses
dka400).
2. Insert the KZPCM Host Adapter DIGITAL OpenVMS driver floppy diskette
in the floppy diskette drive (dva0).
3. The installation process requires three boots:
A. >>>
boot –flag 0,80000 dka400,dkb0,dva0
(where dka400 is the DIGITAL OpenVMS installation CD-ROM,
dkb0 is the target device for the installation, and dva0 is the KZPCM
Host Adapter driver distribution floppy).

DIGITAL UNIX Installation
This chapter describes briefly the DIGI TAL UNIX driver that enables the KZPCM Host
Adapter to work with the DIG I TAL UNIX operat ing syst em , and t ells you how to install t he
driver in the host computer.
6.1 DIGITAL UNIX Driver Description
DIGITAL UNIX is Digital Equipment Corporation’s Alpha system UNIX
operating system. The DIGITAL UNIX driver enables the use of Ultra SCSI
disks to maximize the PCI-based Alpha system I/O throughput and storage
capacity. The driver is optimized for minimum load on the system processor(s)
by use of a loadable SCRIPT to handle low-level SCSI operations and minimize
the number of interrupt requests to the system. For the case of small I/Os, the
driver interrupts the host only once for each I/O, compared with several
interrupts per I/O for other types of SCSI adapters.
The DIGITAL UNIX driver features support for:
Ultra SCSI at speeds up to 40 Mbytes/second per channel.
•
Synchronous negotiation (including Fast/Ultra SCSI)
•
Single-interrupt-per-small-I/O technology for maximum I/O throughput with
•
minimum CPU overhead.
Simple installation via
•
Version 4.0D or later.
•
Wide negotiation
•
Tagged command queuing.
•
Multiple Logical Unit Numbers (LUNs).
•
Disconnect/Reconnect.

6.2 Installing the DIGITAL UNIX Driver
Do the following procedure to install the DIGITAL UNIX driver. The procedure
assumes that the hardware is already installed in the system.
6.2.1 Driver Installation
1. Mount the installation floppy disk:
#
mount –r /dev/fd0a /mnt
2. Extract the device driver using the
#

The
procedure will guide you through the process of installation and
setld
configuring the device driver.
3. Unmount the installation floppy disk.
#
umount /mnt
NOTE
If the k ernel conf iguration f ile spec ified dur ing the
installation was created by booting
with the KZPCM hardware in the system, then it
will contain PSIOP bus entries for the KZPCM.
These entries need to be edited in the
configuration file before the new kernel is
compiled with
Bus Re-numbering
instructions.

(answer n to the question about editing the configuration file)
5. After the successful build of the kernel, save the original kernel and copy the
new kernel to the root directory.
#
cp /vmunix /vmunix.sav
#
cp /sys/NAME/vmunix /vmunix
(where
NAME
is typically
the host name)
6. Reboot the system.
#
shutdown –r now
6–2 EK–KZPCM–UG. B01
Chapter 6. DIGITAL UNIX Installation
6.2.2 Addition of New Hardware After KZPCM Installation
If a new kernel configuration file is created after the installation of
the ITPSA driver, ITPSA entries will need to be re-added in order for the ITPSA
driver to get compiled into the new kernel.
This will be the case if the ‘sizer –n’ command is used, or if the ‘doconfig’
command is used without any arguments (for example when adding new
hardware to the system).
To add ITPSA entries to a kernel configuration file, execute the script
#/usr/opt/ITPSA100/conf/itconfig.sh <SYSCFGFILE>
(where <SYSCFGFILE> is the name of the kernel configuration file to modify).
The script will retrieve the values entered during the initial installation of the
ITPSA driver for number of adapter and Ethernet entries to add.
To change the number of adapter or Ethernet entries to add, edit the file:
#/usr/opt/ITPSA100/data/itconfig.dat
The formatting of this file is strict. Be sure to only change the number of
adapters or Ethernet entries and nothing else. Also be sure that no spaces exist
between the NADAPTERS or NETHERNETS keywords and the values (i.e. it
should be "NADAPTERS=4", and not "NADAPTERS = 4", etc).
NOTE
In some cases it might be necessary to review
Subsection 6.2.3 to ensur e that the SCSI bus is
re-numbered properly.
6.2.3 Bus Re-numbering
The process of booting
genvmunix
SCSI buses as PSIOP buses. When the ITPSA driver is installed it will renumber the KZPCM SCSI buses. If the system disk is attached to the KZPCM,
the re-numbering will cause the system to fail to boot because the system disk
will not match the entry in the
bus renumbering for the KZPCM adapters. The procedure assumes that the
ITPSA driver has been installed in the system and that entries have been created
in the system kernel configuration file for the ITPSA driver (this is done by the
ITPSA installation procedure).
EK–KZPCM–UG. B01 6–3
to scan for hardware will identify the KZPCM
/etc/fstab
file. The following procedure will avoid
KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter
1. The PSIOP driver will attach to the KZPCM SCSI adapter before the ITPSA
driver is attached. You must identify the SCSIn buses that have 53C875
devices attached to the PSIOP driver. Execute the following:
# uerf -R -r 300 | more
Identify the SCSI[0-9] buses that have the PSIOP driver and the warning
"Using unsupported 53C875 scsi chip"
Example:
Mar 9 21:00:00 node vmunix: psiop0 at pci3000
slot 0
Mar 9 21:00:00 node vmunix: siop_pci_initialize:
Warning - using unsupported 53c875 scsi chip
Mar 9 21:00:00 node vmunix: loading SIOP: ...
Mar 9 21:00:00 node vmunix: scsi1 at psiop0 slot 0

Mar 9 21:00:00 node vmunix: loading SIOP: ...
Mar 9 21:00:00 node vmunix: scsi2 at psiop0 slot 0
NOTE
In this example "scsi1" and "scsi2" are the SCSI
buses with the KZPCM attac hed (53c875). You
should find two SCSI buses per KZPCM installed.
2. Edit the kernel configuration file that you specified during the KZPCM
installation procedure.
a) Identify the "
controller scsi[0-9] at psiop[0-9]
"
entriesthat match the ones from the boot log and comment them out by
placing a '#' at the beginning of the line.
b) Edit the "
controller scsi[0-9] at itpsa?
" entries so that
the scsi[n] numbers match numbers match the scsi[n] bus numbers of
the controller lines you commented commented out in step (a).
NOTE
The required entries might not be adjacent.

KZPCM Host Adapter Diagnostics
This chapter describes procedures you can use both to diagnose problems that might
occur in the Host Adapter and to verify that the Host Adapter is operating correctly.
The KZPCM Host Adapter is tested completely before it is shipped. If you
experience a problem with the Host Adapter or need to verify that it is operating
correctly use the following procedures.
8.1 Locating the KZPCM Host Adapter in the System
Depending on the configuration and type of the KZPCM host system, the SCSI
and Ethernet ports are given different designations. The designations are in the
following format:

Note that the last entry,
Hose 0, Bus 3, PCI,
consists of two 53C875
devices and a DE500-AA device. This last entry is the KZPCM Host Adapter in
this system. This can be verified by the MAC address (00-06-2B-00-04-8B in
the example above), which is attached to the module with a label. Write down
8–2 EK–KZPCM–UG. B01
Chapter 8. KZPCM Host Adapter Diagnostics
the Ethernet MAC address for later identification of the module, and write down
the SCSI port names (in this example pkb0 and pkc0) and the Ethernet port name
(in this example ewa0). After you have identified the SCSI and Ethernet ports
you can test them, as described in the following sections.
8.2 Determining the KZPCM Host SCSI ID
Use the show device console command to list all of the devices in the system,
identify the related port entries (in this example PKB0 and PKC0). The show
device command will list all devices in the system. In the following examples
only the relevant lines are shown.
>>>
show dev
(only the relevant lines of output shown below)
pkb0.7.0.3000.0 PKB0 SCSI Bus ID 7
pkc0.7.0.3001.0 PKC0 SCSI Bus ID 7
Note that in this example both ports are set to SCSI ID 7. If it is necessary to
change the host SCSI ID because of a conflict with another host or a SCSI disk
on the bus, do as follows:
>>>set pkb0_host_id 6 ! SCSI bus port B
This example moved the host adapter SCSI ID to 6 on this bus. You need to to
take care to make sure there was no SCSI disk at this ID before making the
change. The
show device
command should not show a disk entry for
DKB600, e.g., SCSI DISK on port B at ID 6.
NOTE
This change will not take effect until the system
power is cycled off and on.
8.3 Determining Which Drives are Connected to the KZPCM Host
Adapter
Issue the show device command and identify all devices on the KZPCM
controller. The format for disks is
PKc0 port, and n = the SCSI ID times 100. For example:
on controller port C at SCSI ID 5.

8.4 Locating SCSI Device ID Conflicts
The most common SCSI configuration problem is an ID conflict. Each SCSI
device on a port must have a unique ID from 0 – 15, which cannot be the same as
the host ID or that of any other drive.
Note
By default and c onvent ion t he hos t i s alway s at I D

8.4.2 Disk Drives with the Same ID as the Host
The most common result of having disk drives with the same ID as the host is
that

dkb600.6.0.3000.0 DKB600 RZ1CB-CS 0656
In this example a disk drive was set to the host ID of 7. There is actually only 1
disk drive on the bus, but it responds at each ID.

Chapter 8. KZPCM Host Adapter Diagnostics
8.5 Checking the SCSI Bus Termination
A very common SCSI problem is incorrect termination. Refer to Chapter 2,
Installing the KZPCM Host Adapter
, to determine if the bus is terminated
correctly at both ends of the bus, and that no device in the middle has
termination enabled.
8.6 Testing the SCSI Ports
, a built in test at the SRM console of most systems, can be used to
EXER
determine if the SCSI ports and disks are functioning correctly.

Observe the Hard/Soft error counts from the tests. Hard errors should always be
0. Soft errors are usually 0, and if non-zero, usually indicate a bus that is
incorrectly terminated.

KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter
8.7 Testing the Ethernet
After the correct Ethernet port has been located, it can also be fully tested using
the built-in diagnostic
NETTEST
and external loopback test. First you must determine that the
set for the media (wire) type that is connected to the module.
>>>
show ewa0_mode

Be certain that the media type is correct for the network the port is plugged into.
Valid types for this module are:
Twisted–Pair, Fast, or FastFD.
To test the circuitry on the Ethernet port do an internal loopback test on the Host
Adapter by using the
>>>
