Documentation Organization

This manual is organized into the following sections:

Adapter Specification Adapter Configuration BIOS and Firmware Configuration Software Drivers Configuration Utilities

Adapter Specification

Overview

The Compaq VAX™-SCSI Wide Ultra SCSI Host is based on the LSI 53C875 SCSI controller chip. This chip includes the following:

•

Onboard RISC processor

•

Internal 512Byte FIFO

•

Internal 4Kbyte Script RAM

•

One interrupt per I/O scripts

IntraServer’s SCSI script implementation on the Symbios (LSI Logic) 53C875 SCSI processor offloads the CPU to deliver higher efficiency and lower CPU utlization. All low level SCSI functions are completed by SCRIPTS, which only interrupt the host when an I/O is complete. This allows the SCSI interface to perform at a higher I/O rate than previous implementations, which were limited by the processor’s ability to service frequent interrupts.

Adapters designed for systems with a CDAL bus (Compaq adapters versions DS-KZCCA-AB, -BB, -CB and -DB) interface directly to the CPU on the CDAL bus, allowing for maximum I/O bandwidth possible for these systems. Compaq’s DS-KZMCA-AB adapter (currently under development) implements the XMI interface, and is intended to be used in XMI based systems.

The high performance PCI SCSI core is interfaced to the system bus (CDAL or XMI) by use of a Field Programmable Gate Array. The FPGA provides arbitration for the PCI devices (SCSI and Ethernet are available options), interrupt controll a n d data path.

Required Software

IntraServer’s PKW driver, a high performance Wide Ultra SCSI driver is used as the port driver for the VAX-SCSI implementation. PKW is a port of IntraServer’s PKWDRIVER which has been fully qualified by digital, and is now part of the OpenVMS/Alpha distribution (V7.1-2 and V7.2). PKW interfaces with the high performance scripts on the 53C875 to maximize SCSI data throughput while minimizing CPU overhead.

IntraServer has implemented a port naming convention for SCSI devices on PKWdr iver t o maximize the numbe r of SCSI de vices t hat ca n be use d in a cluster without being limited by the SCSI naming convention implemented by OpenVMS. The driver can optionally be set to name the SCSI ports PKW (default), PKX, PKY, or PKZ. This is done so that in cluster applications the SCSI devices on one host system will not conflict with the SCSI devices on another system with the same allocation class.

The in stalla tion procedu re will in quire about the po rt lett er requ ired.

Required VMS Patches

Your VMS system must have all SCSI patches for the version you are running. These patches are available from Compaq on the internet. If your system is not up to date, you may experience SCSI device problems.

Check for the latest patch information for your version of VMS at the foll owi ng T he r e ar e s ome r equ ir e d VM S p atch e s r eq ui red t o cert ai n ver si on s of VMS required to run the Compaq VAX-SCSI option. These are found on the support web site at:

http://ftp.service.digital.com/patches/public/vms/vax/

You must have all SCSI related patches for your version of VMS, for example:

http://ftp.service.digital.com/patches/public/vms/vax/v6.2/vaxscsi01_062.README

If you ar e shadowi ng, you mus t also ha ve all sh adowi ng rel ated p atche s, for example:

http://ftp.service.digital.com/patches/public/vms/vax/v6.2/vaxshad08_062.README

Install all patches before you install the IntraServer driver kit.

Restrictions

The following restrictions apply when using the VAX SCSI option in certain systems. Please adhere to the restrictions below in order to ensure correct operation:

Model Restriction 5140-V1 Takes up DSH42 (async option) Slot

Cannot be used with the KZQSA 5140-V2 Takes up Turbo-channel adapter slot 5140-V3 Cannot be used with KZQSA 5140-V4 Takes up DSH42 (Async option) Slot

Cannot be used with the KZQSA 5140-V5 TBD

Performance

Compaq’s VAX SCSI adapters bring state of the art Ultra SCSI disks and tapes to the VAX architecture, and significantly increase the I/O throughput available.

For single block, sequential I/O (512 bytes) the Compaq adapters are capable of doing 5000 I/Os per second, running OpenVMS to Ultra SCSI disks.

Large I/O throughput is limited more by the CDAL architecture than by SCSI. Sequential I/Os of 127 blocks (65024 bytes) achive 10.3Mbytes/sec.

For comparison, large seq uential reads over DSSI achive 3.3MBytes/sec, and the native narrow SCSI (onboard) achives 3.0Mbytes/sec in equivalent tests.

Adapter Installation

Termination

Compaq VAX™-SCSI Ultra SCSI Host adapters include on-board Differential SCSI drivers and termination. The Comapq adapter is always at the end of the S C SI chain , and the r efore always must termi nate the SCS I bus. An external SCSI Connector and cabling is provided for connection to external SCSI devices.

Correct installation of your adapter requires that you first understand the basic rules of the SCSI bus and correctly configure the termination based on the position of the external devices on the bus. In order for a SCSI bus to operate, it must be electrically terminated at both ends.

Your VAX™-SCSI adapter is at the end of the SCSI bus and will always have termination enabled.

You must pla ce a Differential SCSI terminat or at the LAST device on the SCSI chain. No other device s on the bus should provid e ter mi nation.

5. Replace the system cover, and all external cables.

Configuring the SCSI Bus

Some basic SCSI principles must be applied in order to configure the SCSI bus on your system correctl y. These ar e:

Termination

The SCSI bus must be terminated at both ends, and only at the ends. Configure the termination on your VAX-SCSI adapter using the configuration information in the preceding chapter. Refer to the documentation for each device on the SCSI bus, to ensure:

1. Devices at the ENDS of the bus have TERMINATION

ENABLED (or installed)

2. Devi ces not at the END of the bus have TERM INATION

DISABLED (or removed)

Note: Mo st diff ic ultie s with the SCSI bu s can be traced to impro per

termination and cabling.

Note: Your Compaq VAX™-SCSI card always provides High Voltage

Differential Termination (HVD). You must provide HVD termination af ter the las t dev ic e on the end of the external cable.

SCSI IDs

Each devi ce an d hos t ada pter on the SCSI bu s m ust have a u nique SCS I ID. The host adapter must be left at its default ID of 7.

On a 16 bit (WIDE) VAX™-SCSI bus, each device must have a unique SCSI ID from 0 - 7. The Compaq VAX™-SCSI adapt er de faults to ID 7. All othe r devices on t he bus sh ould be given IDs from 0 – 6. Refer to th e documenta t ion for each of your devi ces for t he method of set t ing the S C SI ID for that device.

NOTE: VAX™-OpenVMS™ does not currently support SCSI IDs above 7.

Refer to your specific operating system for details.

Cabling SCSI Devices

Compaq’s VAX™-SCSI adapters support up to 7 devices per SCSI channel. All device s must be Differenti al SCSI (HVD), an d can in clude Disks, Tapes and RAID devices. Compaq’s SCSI adapters have been qualified with Compaq’s StorageWorks family of storage devices. Devices must be configured external to the system enclosure. Compaq’s VAX™-SCSI adapter is designed to allow SCSI bus lengths up to 25 Meters.

It is highly recommended that a high quality SCSI cable be selected for all device connections, due to the importance of optimal signal integrity, and to ensure compliance with regulatory agency approval for system emissions. Most pr oble ms e n coun tered during the initial instal lation of a SCSI syste m can be traced to improper or low quality cabling and termination. Compaq carries a complete line of high quality SCSI cables which are compatible with Compaq’s VAX™-SCSI adapters, which can be ordered to meet the requirements of your configuration.

Connecting External SCSI Devices

Opt ional cables are available from C om paq for all ext ernal de vices. See t he cable selection table in t his guid e to determine th e correct cable f or your application.

Apply these rules for IDs and termination:

•

Onl y t he end de vice on the bus (last device on the cable) should

have termination enabled

The VAX™-SCSI adapter ALWAYS provides termination

•

Each d evice must have a unique SCSI ID

The VAX™-SCSI adapter is ALWAYS at SCSI ID 7

Device Drivers for OpenVMS™

IntraServer’s OpenVMS™ driver enables the use of Ultra SCSI Differential disks, tapes and RAID enclosures, such as Compaq’s StorageWorks line of disk enclosures, to maximize the VAX™ system’s I/O throughput and storage capacity. IntraServer’s OpenVMS™ drivers are 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, IntraServer’s OpenVMS™ driver will only interrupt the host once for each I/O, compared with several interrupts per I/O for other SCSI adapters. IntraServer’s Ultra SCSI OpenVMS™ drivers also feature:

IntraServer’s Digital OpenVMS™-VAX™ driver fe at ur es:

•

Supports Ultra SCSI at speeds up to 40MBytes/Sec per channel (Ultra-

SCSI peak synchronous rate. Your system will be limited to the

system’s bus bandwidth, which can be below this peak rate)

•

Supports over 5000 single block I/Os per second per channel

•

Supports sy nchronous negotiation (inc lud ing Fast/Ultra SCSI)

•

This installati on pro ce dure will in stall sup port for Intra Ser v er ’s Fast Ethernet and UltraSCSI devices on this machine.

This procedure will start the selected drivers automatically at the end of this installation.

If you do not want to start the drivers automatically at this

time, answer NO to the following question:

* Do you want this procedure to automatically start the drivers? [YES]?

In order to start the IntraServer SCSI support on this system SYS$SY STEM:CON F I G _ PCI must be run ea ch ti m e th e sy st e m bo ots.

IntraServer recommends that CONFIG_PCI is run from the SYS$MANGER:SYCONFIG.COM procedure so that your SCSI devices

are

made available during the normal boot process.

* Do you want thi s pro cedure to mo dify SYCONFIG. C O M automaticall y? [YES]?

Your IntraServer UltraSCSI adapter is capable of SCSI support, if ordered with the SCSI option.

This procedure can install the SCSI D rivers at this time.

* Do you want t o add SCSI suppor t at this time ? [YES ]?

IntraServer support for SCSI Logica l Units (DKW101, DKW102...) is Optiona l, because some older SCSI de vices do not suppo rt LUNs.

* Do you wa nt to support SCSI Logical U ni t s? [NO ] ? y

IntraServer VAX SCSI adapters default to a port letter of "W" and therefore dev ices will be named as fo llows:

Device Name | SCSI ID | LUN

--------------+-----------+----- DKW100 | 1 | 0 DKW101 | 1 | 1 DKW102 | 1 | 2 DKWnnn | | . | | . | | DKW200 | 2 | 0 DKW300 | 3 | 0 DKWnnn | | . | | . | |

if this naming convention conflicts with other devices on your system, you may change the port letter to "X", "Y" or "Z", changing your device names to DKXnnn, DKYnnn or DKZnnn respectively.

* Change port letter from W [N]? y

Enter port letter (W,X,Y or Z) [W] : y

Your I nt raSer v er UltraS CSI ada pter is capabl e of Fast E thern et support, if ordered with the Fast Ethernet option.

This procedure can install the Fast Eth ernet at this tim e.

* Do you want to add Fast Ethernet support at this time? [YES]?

The IntraServer Ethernet port on this machine supports Fast (100Mb/sec ) or Standard (10M b/sec) operation.

Answering YES (def ault) to the question be lo w wil l select 100Mb/sec operation.

Answering NO to the question below will select 10Mb/sec operation.

* Do you wan t t o run FAST (100Mb/sec) eth e rnet? [YES] ?

The IntraServer Ethernet port on this machine supports Cluster traffic over the Fast Ethernet port.

Answering YES (def ault) to the question be lo w wil l allo w cl uster tra ffic to us e t h e fast ethern et port.

Answering NO to the question below will not allow cluster traffic to use the fast ethernet port.

* Do you wan t t o run CLUSTERI N G on the FAST (100Mb/sec) ethernet port ?[NO]? y

Testing Your Installation

Once you have completed the hardware and software installation, your SCSI

disks will be available for use under VMS™. The command:

$show device dk Will display all dk (SCSI ) type devices on your system. Note that your SYS$MANAGER:SYCONF IG.COM fil e has bee n modifi ed,

by including the command $mc config_pci, which will scan the PCI devices on your system, and make them available for use.

If SYS$MANAGER:SYCONFIG.COM is changed by any other application, you will need to re-install this kit.

Once insta l led, your new drives w i ll be fu nctionally eq uival ent to ot her SCSI disks in your system.
