Multi-Hosting

CMD's multi-host solution can support disk, tape, and optical devices including jukeboxes.

It· gives you the ability to completely share an array of disks and tapes between multiple VAX systems running VAX cluster software. Multi-hosting configuration instructions are given in Chapter 4.

Refer to Appendix A for supported disk and tape devices.

Partitioning

CQD-440 gives you the ability to partition devices. Partitioning makes one physical device appear as two or four equal sized logical devices. Partitioning is used for operating systems that do not support large devices such as RT-l1.

Partitioning configuration instructions are given in Chapter 4.

Tape Monitor Utility

The Tape Monitor UtilityTM (TMU) is an application software that works exclusively with CMD SCSI host adapters as an optional feature for

VAX/VMS systems.

This Tape Monitor UtilityTM displays the tape drive vendor identification, drive firmware revision, the remaining tape capacity, percentage/number of rewrites during writes or percentage/number of ECC retrys during reads (see manufacturer's documentation for returns whether percentages or numbers), and current tape operations such as read, write, write file mark, space, rewind,

etc. You can install multiple CQD-440's 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 can also open a file to log all the information during unattended backup.

2-4 Features and Specifications

COD-440

To install the Tape Monitor Utility, follow the instructions given in the accompanying CMD Tape Monitor Utility User's Manual part number

MAN-DOOTMU-OOO and install jumper shunt as given in Chapter 3, subsection

"Tape Monitor Utility and SCSIformat ON-LINE."

SCSlformat ON-LINE

The SCSIformat ON-LINE (FMT) is an application software that works exclusively with CMD SCSI host adapters as an optional feature for

VAX/VMS systems. This SCSIformat ON-LINE allows you to format the disk drives without interfering with the other devices on the SCSI bus. To install

SCSIformat ON-LINE follow the instructions given in the accompanying

SCSIformat ON-LINE User's Manual and install jumper shunt as given in

Chapter 3, subsection "Tape Monitor Utility and SCSIformat ON-LINE."

Hardware Shadowing

The Super Shadow CQD-440/TMS is a hardware variation of the

CQD-440 /TM. Installation and setup of CMD shadowing host adapters are simplified with the CMD On-Board Utilities. This easy to use menu-driven utility allows you to quickly configure virtually any combination of disk shadow sets. See Chapter 4 for Hardware Shadowing Configuration.

The hardware disk shadowing on DEC computers enables simultaneous writing of data to two shadow set members. This provides an exact real-time duplicate data set that can be later retrieved by the user if data on primary disk becomes unaccessible.

The access performance benefits are derived from the ability to read data from a particular disk in the shadow set that responds faster. By adapting specific host adapter resident firmware algorithms, CQD-440/TMS provides incredible performance benefits with disk access time reduced 100% or more during reads.

The hardware-based shadowing technique also results in far less VMS overhead and much higher data availability than software solutions.

You can now configure complete SCSI drive failure tolerant subsystems built around Super Shadow host adapters. When used in conjunction with other

CMD exclusive features like Multi-Host capability, subsystem data availability can be increased substantially.

Installation

This chapter instructs you on configuring the CQD-440 and installing it into the system. Follow the instructions in this chapter in the order presented.

Determining CSR Address

Before you install the CQD-440 SCSI host adapter under the VMS operating system you must determine the Control and Status Register (CSR) address for the CQD-440.

For the CQD-440/TM, two CSR addresses are required. The following proced ure shows one method of determining the new CSR address for the

CQD-440.

WARNING Do not install the new CQD-440 in the system at this time.

ODT instead of the normal 773000G.

18- or 22-Bit Address Selection

The CQD-440 is factory configured to 22-bit addressing which is used in systems with the MicroVAX, LSI-11/23/53/73/83/93 and Mentec MBO, M90,

M100 processors. 22-bit addressing can cause problems if used with an 18-bit processor such as the LSI-11/2. In this case, configure the board to 18-bit by cutting the etch between W32 1-2 (see Figure 3-2 for jumper block locations).

Interrupt Level Selection

Interrupt Level Selection allows you to select the priority of interrupting the

CPU for MSCP devices. The CQD-440 is shipped with interrupt level 4 selected; this is standard interrupt priority for MSCP devices. Interrupt at levelS can be achieved by cutting the etch between W31 1-2.

3-6 Installation

CQD-440

Block Mode DMA

Block Mode DMA allows the CQD-440 to transfer data in blocks rather than single word per memory address assertion. In a Block Mode Direct Memory

Access (DMA) transfer, the starting memory address is asserted, followed by data for that address, and data for consecutive addresses. Because the assertion of the address for other data words are eliminated, higher data throughput can be achieved. The CQD-440 is shipped with Block Mode DMA enabled as shown in Table 3-4.

Adaptive DMA

Adaptive DMA allows the CQD-440 to release the Q-bus after a block (eight words) transfer if other DMA devices assert DMA request. Otherwise, the

CQD-440 will continue the DMA transfer for an additional block then release the Q-bus. Adaptive DMA is implemented to utilize the Q-bus bandwidth.

DMA Dwell Time

DMA Dwell Time is the relaxation period between DMA requests. Normally, if multiple DMA data transfers are performed, consideration must be given to the Q-bus for other system functions, such as communication multiplexer, network, etc. During the DMA dwell time, the CQD-440 will not arbitrate for the use of the Q-bus. You can select the period of the DMA Dwell Time by changing the jumper shunts listed in Table 3-6.

Tape Fast Search Option

When set to the Tape Fast Search mode, the CQD-440 will enable high speed forward and reverse filemark search. VMS may use this mode if you do not attempt a standalone boot or run other programs that require the controller to keep track of the number of data records between filemarks. In VMS standalone boot application, this option needs to be disabled. For the

ISM-II operating system, this jumper shunt has to be installed. CMD recommends you use this option for ULTRIX and UNIX systems. Table 3-8 lists the jumper settings.

Sync/ Async Mode Selection

The CQD-440 comes standard in synchronous (sync) mode. Most SCSI devices support to sync mode. In sync mode, CQD-440 will automatically communicate with each SCSI device connected to find out whether the sync mode is supported by the device.

In async mode, CQD-440 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.

You can change the CQD-440 to async mode using the jumpers listed in Table

3-9; these jumpers control the overall sync/ async mode selection and will override the On-Board Utility sync mode set-up.

Installation

This section gives you instructions for installing the CQD-440 into a system.

Remember to turn off the power of the system and SCSI devices while installing the SCSI cable and terminator.

SCSI Host Adapter 10 Selection

Each device on the SCSI bus requires a unique SCSI identification address

(0-7). SCSI ID 7 has the highest priority on the bus and SCSI ID 0 has the lowest priority. The CQD-440 SCSI Host Adapter is factory configured to SCSI

ID 7. Do not change this setting unless you are setting a multi-hosting configuration (see Multi-hosting in Chapter 4).

SCSI 10

for Target Devices

Each SCSI device (initiator or target) on the SCSI bus requires a unique SCSI

ID number. Since the CQD-440 has been set to SCSI ID 7 (initiator), target devices must be configured from SCSI ID 0 to 6. Factory configuration is four disk drives at SCSI ID

=

0 to 3 and three tape drives disks, 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; otherwise,

do not

change the configuration.

CQO-440

CQD-440 Mounting Slot Selection

The CQD-440 can be installed in any slot of the standard Micro V AX or LSI-II

Q-Bus backplane as long as the Q-Bus interrupt acknowledge/DMA grant daisy chain is not broken.

SCSI Bus Cabling

Single-ended-The CQD-440 provides a 50-pin connector 02) to interface with external single-enged SCSI devices.

• When the CQD-440 and the SCSI devices are installed in the same cabinet which meets EMI/RFI shielding requirements, a 25-signal

twisted-pair cable

must be used for connecting the CQD-440 (2) and the SCSI devices.

• When the CQD-440 and the SCSI devices are installed in separated cabinets, the shielded SCSI cable should be used to meet FCC requirements.

• A minimum conductor size of 28-AWG must be used to minimize noise effects and ensure proper distribution of optional terminator power.

• The maximum cable length is 6.0-meters or 20-feet in single-ended channel.

Differential-The CQD-440 also provides a 50-pin connector (1) to interface with external differential SCSI devices.

• When the CQD-440 and the external SCSI devices are installed in the same cabinet which meets EMI/RFI shielding requirements, a

25-signal

twisted-pair cable

must be used for connecting the CQD-440

(1) and the external SCSI devices.

• When the CQD-440 and the external SCSI devices are installed in separated cabinets, the shielded SCSI cable should be used to meet

FCC requirements. A 25-signal

twisted-pair cable

must be used to eliminate the crosstalk between adjacent signals causing spurious pulses on differential signals which will occur even at slow data transfer rates and short cable distances. Each pair should be connected to the same signal, one wire to the positive and the other wire to the negative signal.

• Cables should consist of conductors of 26-AWG or 28-AWG.

• The maximum cable length is 25-meters or 80-feet in differential channel.

Installation 3-15

CQD-440

SCSI Bus Termination

The CQD440 can be installed in any position of the SCSI cable. If the

CQD-440 is installed in either end of SCSI cable, on-board terminators should remain on board. If the CQD-440 is in the middle of the SCSI bus, on-board terminators should be removed.

Single-ended Active-The

CQD-440 uses active removable terminators for single-ended SCSI. Active termination provides greater noise immunity and more closely matches the cable impedance. The part number for the sips are xxxIII (9 by 110-ohms). They are located in the RP1, RP2, and RP3. See

Figure 3-5 for details.

Single-ended Passive-If

passive termination is desired, the SCSI bus signals should be terminated with 220-ohms to +5-volts and 330-ohms to ground at each end of the cable. The CQD-440 provides on-board removable terminators, for locations RP1, RP2, and RP3. The sips extension numbers must end in 221331. See "Single-ended Active/Passive Termination."

Differential-Every

differential signal pair should be terminated with

330-ohms resistor between the negative signal and +5-volts, 330-ohms between the positive signal and ground, and 150-ohms between the positive and the negative signal at each end of the SCSI cable. The

~QD-440 provides on-board removable terminators (U1 and U2) which are next to the connector J1. RPl, RP2, and RP3 single-ended (active or passive) terminators must be installed at all times when using differenital channel.

SCSI Bus Terminator Power

Any SCSI terminator (on-drive or external) needs to be powered by at least one SCSI device, otherwise the SCSI signals will be pulled down. Typically an initiator (SCSI host adapter) provides the power to the on-board terminator, external SCSI terminator and on-drive terminator when the drive is powered off. Anytime an external SCSI terminator (instead of the on-drive SCSI terminator) is used, the SCSI terminator power option of the CQD-440 has to be enabled, i.e. install jumper shunt at WI or W 6.

A minimum conductor size of 28-AWG shall be employed to minimize noise effects and ensure proper distribution of optional terminator power. The

CQD-440 supplies terminator power to the TERMPWR pin

02, pin 26; J1, pin

25 and 26) and the CDQ-443

02,

pin 38; J1, pin 13 and 38), through a fuse, a diode and jumper block WI for differential and W6 for single-ended (see

Setup

This chapter will assist you in setting up the CQD-440 and your system for use.

On-Board Utility

The CQD-440 SCSI host adapter comes with a general purpose On-Board

Utility for all systems. The On-Board Utility can test the system slot, SCSI cable, and SCSI devices connected to the CQD-440. Accessing the Utility can be done through LSI or VAX system or the RS-232 Port. Be sure to complete utility functions, explained at the end of this chapter.

Accessing the Utility Through the LSI or VAX System

The On-Board Utility Program can be accessed by means

ot

an ODT command for LSI and V AX systems. One example is shown with the SCSI host adapter set to the first disk CSR address. Because the formats and features of the On-Board Utilities for LSI-II systems and MicroV AX systems are similar (except different start up procedures), the MicroV AX utility will be described.

Instructions for using the Disk Utility with LSI-11 Systems are listed below:

1 Halt the processor.

2 Hit the Boot Switch.

3 Enter the CSR address plus 2 (in Octal), a slash, and 123456. For example, for CSR address 17772150 enter:

17772152/005400123456.

CSR addresses can be found in Chapter 3 or Appendix C.

NOTE

The following sections will illustrate the On-Board Utility from the RS-232 Port. There may be some variation in the Main Menu and the SCSI Host Adapter Utility

Menu.

If you are accessing from the Main Menu, simply chose the correct number for each option.

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 LUN offset can be O.

If there exists another MSCP controller with four drives (0 to 3) in a VAX cluster configuration, then the LUN offset should be four or above. In the case that LUN offset is equal to 10, SCSI ID

°

will be DUBIO and SCSI ID I will be

DUBIL The drives will show up as such DUAO, DUAl, DUA2, DUA3,

DUBIO, DUBll (see section, "SCSI 10 for Target Drives" in Chapter 3 for explanation).

4-6 Setup

Formatting the Drive

This section details formatting a drive. The CQD-440 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:

An example below is given for each type of controller to show how the unit numbers can be determined. Refer to Figure 4-7 if necessary.

CQD-4401TM-Default is four disk drives and three tape as shown in Table

4-3. If you have more than four disk drives or three tape drives, follow these guidelines-disk drives must start at SCSI ID 0 and tape drives must start after the last disk drive's SCSI ID number and reconfigure the CQD-44 0 /TM

(see subsection, "Displaying SCSI Devices and Setting Up Configuration").

Note the example .below:

SCSI ID 0 disk

SCSI ID 1 disk

SCSI ID 2 disk

SCSI ID 3 disk

SCSI ID 4 disk

SCSI ID 5 tape

SCSI ID 6 tape

SCSI ID 7 is initiator (CQD-440/TM)

The MU and DU numbers are the unit numbers mapped back to the operating system. If the CQD-440 /TM is configured following these guidelines, you can apply this formula to determine the unit number mapped back to the operating system:

+

=

SCSI ID of the disk drive the LUN offset for disk uni t number for disk

SCSI ID of tape drive number of disk drives

+

LUN offset for tapes

Multi-Hosting Configuration

The following is a list of software requirements for multi-hosting; refer to

Appendix A for supported multi-hosting devices:

• VMS version 5.3 or above

• VAX cluster software must be running on both systems with at least one of the DEC's interconnects operational

• Tape dri~es can only be mounted to one system at a time

• Allocation classes must be the same for all systems when installing disk drives (value must not equal 0).

Using VMS and the CQD-440/TM, you can multi-host by following the instructions below:

1 Configure the CQD-440 to SCSI ID 7 for the first computer; configure the

CQD-440 to SCSI ID 6 for the second computer. If you need to alter the

Host Adapter SCSI ID change the jumper settings as shown in Table 4-4.

If you ever reconfigure the board, you must reset the configuration to default using selection Z. e Select R to toggle SCSI reset. Then set the SCSI reset to

OFF.

Do this f for all SCSI host adapters to be multi-hosted.

Answer Y to reconfigure the adapter.

9 Select C to reconfigure the device. Then configure the CQD-440 for exact number of disks and tapes. This will inhibit scanning of other h host adapters (see Figure 4-9).

If other MSCP disks are in the cluster, follow the rules in the subsection "Changing LUN Offset" in liOn-Board Utility" so that each device has a unique unit number.

Exit out of the On-Board Utility.

NOTE

NOTE

In a multi-hosting system the

physical

disk device name must be identical on both systems.

3 Terminate both

physical

ends of the SCSI bus.

Single-ended-If

the CQD-440 is at either end of the SCSI bus, remove on-board terminators, RPI, RP2, RP3, and use a pass-through terminator as close to the board as possible. If the CQD-440 is in the middle of the SCSI bus, RPI, RP2, and RP3 terminators

must

be removed,

do not

use pass through terminators.

Differential-If

the CQD-440 is at either end of the SCSI bus, remove on-board terminators, UI, U2 and use a pass-through terminator as dose to the board as possible. If the CQD-440 is in the middle of the SCSI bus,

UI and U2 terminators

must

be removed,

do not

use pass through terminators.

In the event that one system becomes inoperable with only two nodes in the

VAX cluster, a quorum disk must be used to count as a vote; this keeps the other system running. Refer to VMS V AXcluster manual order number

AA-LA27A-TE to set up a quorum disk and a VAX cluster.

When running

SCSI Basics

This chapter consists of a SCSI glossary, SCSI commands used by the

CQD-440 for MSCP and TMSCP emulation, SCSI status codes, SCSI messages,

SCSI single-ended and differential signals.

SCSI Glossary

The following is a glossary of frequently used SCSI terms.

Connect-The function that occurs when an initiator selects a target to start an operation.

Disconnect-The function that occurs when a target release control of the

SCSI bus, allowing it to go to the BUS FREE phase.

Initiator-A SCSI device (usually a host system) that requests an operation to be performed by another SCSI device.

LUN-Logic Unit Number.

Peripheral device-A peripheral that can be attached to a SCSI device (e.g., magnetic disk, magnetic tape, or optical disk).

Reconnect -The function that occurs when a target selects an initiator to continue an operation after a disconnect.

SCSI address-The octal representation of the unique address (0-7) assigned to an SCSI device. This address would normally be assigned and set in the

SCSI device during system installation.

SCSI Basics

5-1

COD-440

SCSI ID-The bit-significant representation of the

SCSI address referring to one of the signal lines DB (7-0).

SCSI device-A host computer adapter or a peripheral controller or an intelligent peripheral that can be attached to the

SCSI bus.

Target-A

SCSI device that performs an operation requested by an initiator.

VMS Analyze/Error Utility

The CQD-440 logs controller dependent information in

ERRLOG.SYS

file.

User can use the VMS' ANALYZE/ERROR Utility to open the file

ERRLOG.SYS

and display the error messages for troubleshooting. By including option switches such as

/SINCE=DATE

and

/lNCLUDE=MUBO,

you may define the time reference and device. To enter the ANALYZE/ERROR

Utility, log onto the system and enter the following command:

analerrlsince=ltimellinclude=ldevicel

Some examples are shown by the following:

To view all errors that VMS has logged, enter:

analerr

To view the errors only on tape devices, enter:

anal errl inc=tapes

To view the errors that have occured only on one tape unit (MUBO), enter;

analerrlinc=mubo analerrlinc=(ptb,mubo>

To view the MUBO errors that occured on April 20, 1990 since 14:22 (02:22

gggg-the SYSIDHIGH

number which is 8000 plus the

NEXUS

number.

hhhhhhhh-the

SYSIDLOW

number which can be obtained after the controller is connected by using the

SYSGEN

utility

SHOW/UNIBUS.

The newly attached controller will be seen at the CSR address previously specified followed by the

SYSIDLOW

number seen in (hhhhhhhh).

[EXAMPLE] you may wish to connect a tape drive to a MicroVAX 3300.

This tape drive is the third MU: device to be added to the Q-bus. The

AUTOCONNECT

recommended CSR for this device will not be used but the CSR of 760444 will be used instead with a VECTOR of 340 on UBO.

3 View the configuration files by entering the following line at the system prompt:

MCSYSGEN

SHOWICONFIG

The screen displays the configuration as shown in Figure D-1:
