Features and Specifications

This section briefly describes the CBI-I0I0 V AXBI SCSI Host Adapter and details its specifications.

CBI-1010 Features

The CBI-I0I0 is an intelligent high performance VAXBI SCSI host adapter that is fully compatible with the DEC Mass Storage Control Protocol (MSCP) and Tape Mass Storage Control Protocol (TMSCP). Each CBI-I0I0 is fully licensed by Digital and is built around DEC's own BIIC interface chip.

The CBI-I0I0 can be used with the 5800, 6000, 8000, and 9000 series V AXBI systems. It supports VMS, UL TRIX, and selected UNIX operating systems which use DU!TU drivers.

The CBI-I0I0 supports either a single-ended or differential SCSI channel. A single-ended SCSI channel can be used for connecting up to 9.9 feet of cable (when the transfer rate is 10 MBytes/second) while a differential SCSI channel can be used to connect up to 80 feet of cable.

The CBI-I0I0 features Octaword DMA master transfers, virtual data buffer, command queuing, dynamic defect management, standard SCSI bus

arbitration, disconnect and reconnect capabilities, and multiple host

capability. Up to seven SCSI devices (either single-ended or differential) can be connected to the CBI-I0I0 SCSI port with SCSI bus data transfer rate up to 10-MB/sec in synchronous (sync) mode and 7-MB/sec in asynchronous (async) mode.

Multi-Hosting

CBI-IOIO gives you the ability to completely share an array of disks and tapes between multiple VAX systems running VAX cluster software. CMD's

multi-host solution can support disk, tape, and optical devices including juke- boxes. Multi-hosting instructions are given in Chapter 4, under

II Additional Utilities." Refer to Appendix A for supported disk and tape devices. Refer to Chapter 4 for configuration instructions.

Features and Specifications 2-3

CBI-1010

Tape Monitor Utility

The Tape Monitor UtilityTM (TMU) is an application software developed by CMD Teclmology and work exclusively with CMD SCSI host adapters as an optional feature for VAX/VMS systems.

This Tape Monitor UtilityTM runs under VMS and displays the tape drive ven- dor identification, drive firmware revision, the remaining tape capacity, per- centage of rewrites during writes or percentage of ECC retrys during reads, and current tape operations such as read, write, write file mark, space, re- wind, etc. You can install multiple CBI-IOIOs and tape drives in one site and observe all tape activity from any VAX terminal locally or across the network without any additional add-in hardware. You also can open a file to log all the information during unattended backup.

To install the Tape Monitor Utility, use On-Board Utility (Chapter 4,

subsection ^1/ Additional Utilities") to enable TMU since the factory setting for TMU OFF. Then follow the instructions given in the accompanying CMD Tape Monitor Utility User's Manual part number MAN-OOOTMU-OOl.

SynclAsync Mode

The CBI-IOIO comes standard in synchronous mode. Most SCSI devices support synchronous mode. However, you can change the CBI-IOIO to asynchronous mode using the On-Board Utility in Chapter 4.

In Sync mode, CBI-IOIO will automatically negotiate with each SCSI device connected to find out whether the Sync mode is supported by the device.

In Async mode, CBI-IOIO will communicate with the SCSI device

asynchronously even if the SCSI device supports Sync mode. Most of the Sync SCSI devices also support Async mode.

CBI-1010

Cabling

The CBI-1010 will operate in single-ended or differential mode; however, CMD Technology strongly recommends the use of differential mode when the data transfer rate exceeds five megabytes per second. If you have no choice but to use single-ended mode at a high transfer rate, the SCSI-3 proposal rec- ommends that the total internal and external cable length should be no longer than three (3) meters or 9.9 feet when the transfer rate is 10 MBytes/second.

Furthermore, the single-ended cable should meet or exceed the following specifications.

Table 2-5 Cable Specifications

Characteristic Impedance Signal Attenuation Pair-to-pair Propagation Delay Delta

DC Resistance Termination

No less than 90 ohms and no greater than 140 ohms

.095 dB maximum per meter at 5 MHz .15 nanoseconds maximum per meter

.23 ohms maximum per meter at 20 degrees C

The single-ended daughter card adapter for the CBI-1010 employs active ter- mination. Some SCSI devices still use passive termination, which is inade- quate at high transfer rates. If your system is running in single-ended mode at transfer rates in excess of five megabytes per second and the CBI-1010 is at one end of the SCSI bus, you must use active termination or some other type of high-performance termination at the other end of the bus.

Switching Between CBI-1010/M and CBI-1010/MB

Both the CBI-lOlO/M and CBI-lOlO/MB support disk drives only, but the CBI- 1010/M offers KLESI emulation, while the CBI-lOlO /MB offers KDB50 emula- tion, which is necessary for bootability on VAX 6000 systems. Switching be- tween the CBI-lOlO/M and CBI-IOIO/MB models is a simple matter of chang- ing the PAL at location U9 and either removing or installing the jumper at WS. All CBI-IOIO/M adapters come with PAL PIK29 installed at U9 and PAL PIK58A as an accessory. Likewise, all CBI-IOIO/MB adapters come with PAL PIK58A installed at U9 and PAL PIK29 as an accessory.

Be sure to turn off power to the adapter before you switch the PAL at U9. Use a screwdriver to pry the PAL loose and then remove it with your fingers. In-

sert the alternative PAL and press down until it is fully seated. Make sure that the alignment of the notch at one end of the PAL is identical to the sur- rounding chips. This will assure a proper pin-one match. Before restoring power, change the jumper at W5 to the appropriate setting for the model you desire. Table 3-3 shows the EPROM and jumper settings for each model.

Care must be taken when installing a CBI-I0I0 to avoid having the operating system change the physical device names of the currently installed devices.

During auto configure, each device found is given a unique device name. The device names are expressed as:

ddcu where

dd

=

=

=

The device name is determined by the physical address of the controllers port registers OP /SA). Since these addresses are fixed within the CBI-I0I0, there are no concerns with configuring the device type. Refer to Chapter 4, Table 4-1 for unit numbers.

The controller designator is derived by the operating system as it scans I/O space. The first MSCP disk controller found is given the letter' A', the second MSCP disk controller 'B' and so on. This will generate devices DUAx/PUAx, DUBx/PUBx, incrementing the controller letter until all disk controllers are found. The same is true for each TMSCP tape controller, yielding devices MUAx/PTAx, MUBx/PTBx and so on.

The scan will start at node 0 and will work its way up to the last node ID within the system. On native BI systems (Le. 8200/8250/8350), the node ID of the BI is the system node ID. In these systems, the system ID's range from

o

CBI-1010

On systems where the BI is the system I/O bus (i.e. 58xx, 85xx, 8700, 8800 and aIl6000's), the system node ID does not match the BI node ID. For example, a VAX 6000 machine has 240 system node ID's. The XMI bus has 15 nodes each logically capable of containing a bus adapter with 16 node ID of its own.

Physically this arrangement is not permissible, however, this is how VMS looks at the system.

Table 3-4 shows a map of system node ID's for a VAX 6000 type machine.

It is desirable to install the CBI-I0I0 at a system node ID that will not change the physical device names of the currently installed devices. This is

accomplished by installing the CBI-l0l0 at a higher system node ID than any other currently installed device of the same type.

The CBI-I0I0/T is device type PT /MU and should be installed at a higher system node ID than other TMSCP tape controllers. The CBI-I010 /M and CBI- 1010/MB is a device type PU/DU and should be installed at a higher system node ID than other MSCP disk controllers. The CBI-I0I0/TM is a device type of PU /DU and PT /MU and should be installed at a higher system node ID than other MSCP disk and TMSCP tape controllers.

Installation 3-5

CBI-1010

If you do not adhere to these guidelines, currently installed devices that have a higher system node ID than the CBI-lOlO will have their controller designa- tor changed (incremented by the number of CBI-lOlO's installed).

As an example, if the current system has a KDB-50 disk controller installed at XMI node IS, BI node 4, (system node ID 228) and a CBI-lOlO/M,

CBI-lOlO/TM or CBI-lOlO/MB installed at XMI node 14, BI node 4, (system node ID 212), the controller designator for the KDB-50 will be incremented from' A'to 'B' and the CBI-lOlO will have the controller designator of 'A'.

Differential Mode

The CBI-lOlO supports either single-ended or differential SCSI modes. The CBI-lOlO SCSI port is factory configured to your specifications. If for any rea- son you need to convert the CBI-lOlO from single-ended SCSI mode to differ- ential, follow these instructions.

NOTE Use only the components supplied by CMD.

1 Remove the single-ended SCSI daughter card (CBI-lOll) from the lower left comer of the CBI-lOlO board.

2 Install the differential SCSI daughter card (CBI-1012) at the same loca- tion of the CBI-lOlO board. Make sure to align Jl of the daughter card with Jl of the CBI-lOlO board. See figure 3-3.

CBI-1010

Installing the CBI-IOIO involves installing the board, cables, terminating the SCSI bus, identifying and testing SCSI devices with the On-Board Utility. This section explains these topics prior to listing installation procedures; carefully read the explanations first.

SCSI Cabling

The V AXBI systems provide two 30-pin connectors in the backplane for every one of the VAXBI Zero Insertion Force (ZIF) connectors JC, JD, and JE. The 30-pin connector on the component side of the CBI-IOIO is defined as

connector CONI. The 30-pin connector on the solder side of the CBI-IOIO is defined as connector CON2 (see Figure 3-4 for details). Table 3-5 lists the connectors and cables for the CBI-IOIO.

Table 3-5 Connectors and Cables Connector

JE

Connector - CONl Single-Ended/Differential signals

Connector - CON2

On-Board RS-232 Utility & Single- Ended/Differential signals

The CBI-IOIO comes with one three-foot SCSI I/O cable (including RS-232 utility interface) and system back panel adapter kit. The I/O cable is a 60-con- ductor cable. One end has two 30-pin connectors and the other end has 50-pin SCSI connector and a IO-pin connector.

Installation 3-9

CBI-1010

NOTE CMD strongly recommends the use of differential mode in systems employing transfer rates in excess of five megabytes per second. If you have no alternative but to use single-ended mode, the SCSI -3 proposal recom- mends that the total length of the SCSI cable be no longer than three meters (about 9.9 feet) at 10 megabytes per second. See page 2-6 for more details.

SCSI Terminator Power

Typically the initiator (SCSI host adapter) supplies terminator power, +5-volts, to the SCSI bus. Because the CBI-lOlO is considered an initiator to the SCSI devices, the terminator power option of the CBI-lOlO needs to be enabled.

The CBI-lOlO supplies terminator power to the TERMPWR pins of single- ended/ differential SCSI connector (JE) through a polyswitch and jumper block, WB. (Check Tables 5-5 and 5-6 for pin assignments.)

SCSI 10 for Host Adapter (Initiator)

Each device on the SCSI bus requires a unique SCSI Identification address (0 to 7). SCSI ID 7 has the highest priority on the bus and SCSI ID

a

The CBI-lOlO plays the role of initiator and is factory configured to SCSI ID 7.

To alter the Host Adapter SCSI ID, change NOVRAM settings through the On-Board RS-232 Utility given in Chapter 4.

CBI-1 010 Installation Procedures

1 Make sure the system is powered OFF. Make sure the CBI-IOIO is configured as given in the section, "Hardware Configuration."

WARNING Make sure you are wearing anti-static wrist straps.

2 Choose a correct slot for installing the CBI-lOlO by reading the section

"System Node ID."

3 Install the CBI-lOlO in the correct slot with the ZIF connectors set into the system's backplane; push the ZIF handle down to clamp the CBI-IOlO into place.

Installing SCSI Devices

This section details installing devices from the connectors of the back panel adapter kit to the SCSI devices~ Read carefully the subsections, "Cable

Specifications" and "SCSI ID for Target Devices" before installing the devices.

Cable Specifications

Single-ended and differential cable specifications vary; see the appropriate paragraph below for cable specifications before attempting to install devices.

See page 2-6 for a discussion of cabling issues in systems running at high transfer rates.

Single-ended:

• When the CBI-IOIO and the SCSI devices are installed in the same cabinet that meets EMI/RFI shielding requirements, a 25-conductor twisted pair ca- ble must be used for connecting the CBI-IOIO (JE) and the SCSI devices.

• When the CBI-IOIO and the SCSI devices are installed in separate cabinets, a shielded twisted pair cable must be used to meet FCC requirements.

• A minimum conductor size of 2S-AWG must be used to minimize noise effects and ensure proper distribution of optional terminator power.

• The maximum cable length is 3.0 meters or 9.9 feet in single-ended mode at 10 megabytes per second.

Differential:

• When the CBI-IOIO and the SCSI devices are installed in the same cabinet that meets EMI/RFI shielding requirements, a 25-conductor twisted pair ca- ble must be used for connecting the CBI-IOIO (JE) and the SCSI devices.

• When the CBI-IOIO and the SCSI devices are installed in separated cabi- nets, a shielded twisted pair cable must be used to connect the SCSI de- vices from the back panel adapter kit meeting FCC requirements. Other- wise, crosstalk between adjacent signals causing spurious pulses on differ- ential signals will occurs even at slow data transfer rates and short cable distances. Each pair should be connected to the same signal, one wire to the positive signal, and the other wire to the negative.

• Cables should consist of conductors of 26-AWG or 2S-AWG.

• The maximum cable length is 25 meters or SO feet in differential mode.

SCSI 10 for Target Devices

Each SCSI device (initiator or target) on the SCSI bus requires a unique SCSI ID number. Since the CBI-IOIO has been set to SCSI ID 7 (initiator), target

3-14 Installation

CBI-1010

devices must be set from SCSI ID 0 to 6. Normally, the assignment of SCSI Target ID starts with SCSI ID 0 on single function boards.

The factory setting of the CBI-I0I0/TM is four disk devices (SCSI ID=O to 3) and three tape devices (SCSI ID=4 to 6). If you have more than four disks drives or three tapes drives you must use the On-Board Utility to change the configuration; if you do not, you do not need to change the configuration.

SCSI Device Installation Procedures

To install SCSI devices follow the procedures below:

1 Connect SCSI cables as listed below for the specified mode:

For single-ended mode: Connect a SCSI cable from the back panel at the la- bel "Single-Ended" to the SCSI devices (see "Cable Specifications"). The total of the internal and external cable lengths must not exceed 9.9 feet at 10 MBytes/ second. See Figure 3-10.

For differential mode: Connect a SCSI cable from the back panel at the la- bel "Singled-Ended" to the SCSI devices (see "Cable Specifications").

The total of the internal·and external cable lengths must not exceed 80 feet. See Figure 3-10.

Setup

This chapter will assist you in setting up the CBI-IOIO and your system for use.

On-Board Utility

The CBI-IOIO SCSI host adapter comes with the general purpose RS-232 util- ity for all DEC VAXBI systems. The On-Board utility can test the VAXBI slot, SCSI cable, and SCSI devices connected to the CBI-IOIO. Be sure to complete utility functions, explained at the end of this chapter.

Accessing the Utility

To access the RS-232 utility, follow the instructions below.

1 Connect a terminal to the CBI-1010's RS-232 port (DB-25 connector or DEC compatible RJ-11/Modified Module 423 Jack connector of the back panel adapter kit).

2 Set the terminal baud rate to 9600 (8-bit data, I-stop bit, no parity).

4 Refer the the next subsections for configurations. When completed, unplug the terminal, reset the system, and boot. DO NOT use the On- Board Utility while the system is running.

Changing LUN Offset

When a system has a HSC or in a VAX cluster it will be necessary to

change the LUN (Logical Unit Number) offset. Each MSCP drive requires a different Unit Number so that the unit numbers are not duplicated. If there are no other MSCP controllers in the system, the L UN offset can be

o.

If there exists another MSCP controller with four drives (0 to 3), then the LUN offset should be four or above. In the case that LUN offset is equal to 10, SCSI ID 0 will be DUBIO and SCSI ID 1 will be DUB1l. The drives will show up as such DUAO, DUAl, DUA2, DUA3, DUBIO, DUB11 (see section, "SCSI ID for Target Drives" in Chapter 3 for explanation).

1 Select option 1 from the main menu for disk drives; 6 for tape drives.

3 At the statement: SAVE NEW CONFIGURATION (Y or N)? enter Y.

4 The monitor will display COMPLETE when finished executing.

Formatting the Drive

This section details formatting a drive. The CBI-IOIO issues Format Unit Command to the selected SCSI disk drive and requests it to map out the defects on the Manufacture Defect List (MDL). Remember formatting a drive will rewrite all the sectors of that drive.

CMD recommends that you format all new drives. To format a drive, follow the steps below:

1 Select option 2 from the main menu.

2 Enter the device number from 0 to 6 in the statement: ENTER DEVICE NUMBER 0 TO 6 :

3 At the statement: *** WILL DESTROY DATA ON DEVICE X, ARE YOU SURE? en- ter Y if you want to continue.

4 The monitor displays WAIT while the drive is executing the format process.

5 The monitor will display COMPLETE when finished executing.

Qualifying the Drive

After formatting the device, CMD recommends you qualify devices by running this procedure at lease once without errors detected. The qualify program writes different patterns to the drive and then verifies the data. If there are any bad sectors, the sectors will automatically be replaced and the statement XX XXXXXXXX BAD BLOCK REPLACED will appear. Follow the

instructions below for qualifying a drive.

1 Select option 3 from the main menu.

2 Enter the device number at the statement: QUALIFY DEVICE NUMBER

<0 TO 6>:

3 At the statement: *** WILL DESTROY DATA ON THIS DEVICE, ARE YOU SURE?

enter Y if you want to continue.

5 The monitor will display TESTING LOOP COUNT AND BLOCK NUMBER:

6 Press [BREAK] to exit back to the main menu after you are satisfied with the qualifying process.

Manually Replacing Bad Sectors

This option allows you to replace bad sectors manually. The controller

supports dynamic defect management which replaces defective sectors on-line so there is no need to manually replace bad sectors. However, if you wish to replace bad sectors manually follow these instructions; remember that any data in the sector will be lost:

1 Select option 4 from the main menu.

2 Enter the device number at the statement: DEVICE NUMBER? DEV <0 TO 6>:

3 Enter the logical block number in HEX at the statement: ENTER THE BAD BLOCK NUMBER <HEX>:
