1.1 9032-5 Functions and Features (1)

This part of the presentation discusses the advanced functions and features ofthe 9032-5.

The 9032-5 provides double the ESCON port capacity of its predecessor, the9032-3.

The 9032-5 offers any to any connectivity for its full range of 248 ESCON ports.All ESCON ports support attachment of channels, control units, serial CTCs,converters (for attachment to convertors two 9032-5 ESCON ports are defined ashaving a dedicated connection) and other ESCON Directors.The 9032-5 ESCON will also support up to 16 FICON Bridge cards. Each FICONBridge card can support 1 FICON port. The internal matrix connections from theFICON Bridge card can be to any ESCON port that logically connects to aESCON interface control unit or an ESCON serial CTC channels. The externalconnection to the FICON Bridge card can only be to a S/390 FICON channel inFCV mode. FCV mode is FICON ConVersion mode.

The 9032-5 supports both LED and XDF ESCON ports.

The minimum number of ESCON ports on a 9032-5 is 24 (this is 3 ESCON portcards) and the maximum is 248 ESCON ports (this is 31 port cards). Theminimum number of FICON Bridge ports on a 9032-5 is zero and the maximum is16 (this is 16 FICON Bridge cards). Together the number of ESCON port cardsand FICON Bridge cards in a 9032-5 cannot exceed 31.

Up to 248 ESCON Ports with any to any connectivity, with upto 124 active simultaneous ESCON connections

There are 8 ESCON ports per ESCON port cardUp to 16 FICON Bridge Ports with any FICON to ESCONconnection, with up to 120 simultaneous communicationpaths

This table compares the features available on the 9032-3, 9033-4 and 9032-5.Some highlights of the comparison are:

The 9032-5 provides double the port capacity of the 9032-3. The 9032-5 offers greater flexibility in port configuration.

The 9032-5 supports a higher maximum number of ports than the 9032-3 inall categories.

The 9032-5 supports a lower minimum number of ports than the 9032-3 inall categories.

Logical partitioning. The redundant power supply feature that was an option on the 9032-3 is

standard on the 9032-5. The 9032-5 also offers two new features, logical partitioning which is standard

and a spare ports card which is optional. Both of these features will bediscussed in detail.

Features. These are shown in order of preference. The reliability of all of these

components is very high, so other factors should be taken into consideration inthe selection of appropriate features for each environment.

The CTP Enhanced Availability Feature provides redundancy for the CTP cardfunction, allows concurrent replacement of a CTP card and allows concurrentLIC changes. LIC updates are disruptive if the CTP Enhanced AvailabilityFeature is not installed.

The MXC/MXS Enhanced Availability Feature provides redundancy for theMXC/MXS card function and allows for concurrent replacement of MXC andMXS cards.

The TKRG (Token Ring) Enhanced Availability Feature provides redundancyfor the TKRG card function. The TKRG card can be replaced non-disruptivelyeven when the TKRG Enhanced Availability Feature is not installed.

In an environment where high availability is required all Enhanced AvailabilityFeatures should be installed.

The spare ports card features are discussed with the next diagram.

Feature codes 5700, 5701, 5702 and 5703 (required when FC 5500 is installed)optional) or 6700, 6701, 6702 and 5703 (required when FC 5500 is installed) arerequired to be installed on the 9032-5 for the 9032-5 to support FICON. Thesefeature codes provide a new MXC card, new 3.3 volt power supplies, the consoleapplication code to support FICON, and a new redundant MXC card. The 570xgroup of feature codes will be provided as a result of ordering a FICON Bridgeport card (FC 5260) for an already installed 9032-5 that is not FICON enabled.The 670x group of feature codes will be provided as a result of ordering a new9032-5 (post June 1999).Feature code 5902 should be ordered if the 9032-5 is going to replace a 9032-2and 5903 should be ordered if the 9032-5 is going to replace a 9032-3, and thecustomer wants the same port address scheme. The migration from a 9032-2 or9032-3 to a 9032-5 is simplified if the port addresses on the old ESCON Directorare provided for on the new ESCON Director because the required I/O pathrouting definition changes (destination port addresses) will be minimized.The port addressing scheme for the 9032-5 is different from that of the 9032-2 or9032-3. If the full complement of port cards is not ordered, the default addressrange may not overlap with the existing address range on the ESCON Directorthat is to be replaced. Feature codes 5902 and 5903 will ship a 9032-5 with portcards positioned to correspond with the address ranges of the 9032-2 or 9032-3respectively.

If neither of the feature codes is ordered, the port cards can be repositioned bythe service representative at installation time to satisfy customers port addressrequirements. This applies to both the ESCON and FICON-bridge port cards. Seealso 1.10, FICON Bridge Card Layout on page 13 for recommendations onwhere to install the FICON Bridge cards.

Another option may be to use the ESCD Console to assign port addresses otherthan the defaults to the installed ports, but this is not recommended.

For information on migration to the 9032-5 (with less than 248 ESCON ports)from a previous ESCON Director Model (which may have a different port number6 IBM ESCON Director 9032-5 Presentation

scheme) refer to Chapter 8, Migration to the 9032-5 on page 103. Also theexisting configuration on a previous ESCON Director model may not be suitablefor the 9032-5 in trying to meet a systems current availability requirement due tothe change in the quantity of ports per ESCON port card. The 9032-2 and the9032-3 both had 4 ports per ESCON port card, whereas the 9032-5 has 8 portsper ESCON port card.

1.5 Spare Ports Card

The logical port swap facility that was available on the 9032-3 is also available onthe 9032-5. This facility allows any failed ESCON port to be swapped with anyother ESCON port so that operation of the attached component can continue.This process relies on a unused (free) port of the correct ESCON port type (LEDor XDF) being available or being able to be made available.The 9032-5 ESCON spare ports feature is an enhancement to the basic portswap facility.

If the spare ports feature is installed, four additional ESCON ports will beavailable for port swapping in the event of port failures or for problemdetermination. This eliminates potential difficulty in trying to obtain an unusedESCON port if problems arise. The spare ports are not available to provideadditional connectivity. They can only be used as substitutes for existing ESCONport addresses.

The spare ESCON ports card feature provides anadditional 4 ports that can be used in the event ofESCON port failuresThis is in addition to the standard any to any port swapcapabilityThe ESCON ports on the spare ports card cannot beused as normal additional portsThe spare ESCON ports card may be either:

4 LED ESCON ports - FC5240OR

2 LED and 2 XDF ESCON ports - FC5250Can provide higher availability during maintenance andrepair activityProvides a useful problem determination tool

1.7 Hardware Components (1)

This diagram describes the function of some of the hardware components of the9032-5.

Operator Panel

The operator panel includes the Initial Machine Load (IML) button, System ErrorLED indicator and Power-on LED indicator. The IML button is protected by thefront cover when the door is closed. IML reloads the Licensed Internal Code (LIC)and resets all the hardware, except the MXC/MXS and DVP cards, withoutswitching off power.

The operator panel also includes a Liquid Crystal Display (LCD) that can displaystatus and event messages using two 16-character lines. Four buttons are usedto control information displayed on the LCD.

Control Processor (CTP) CardThe CTP card contains the microprocessor and associated logic that providesoverall coordination for the director. The CTP card initializes hardwarecomponents of the system after power-on or reset. While in operation the CTPcard supports the director Control Unit Port (CUP), maintenance port, operatorpanel, ESCON port exception handling and error recovery.

Device Port (DVP) CardsThe ESCON DVP card provides the hardware interface to the ESCON fiber optic

interfaces for ESCON fiber optic media. Fiber cables access to the ESCON LEDports is by using IBM duplex connectors and ESCON XDF ports using FCSconnectors. XDF cables with IBM duplex connectors cannot be connected to theESCON XDF ports without the use of an adapter.

FICON Bridge Card

The FICON Bridge card is the hardware interface to the FICON FCS fiber opticmedia, which requires that 9 micron single mode fiber cabling be used.

It is possible to re-use multi-mode fiber. If this is required, then a ModeConditioner Patch (MCP) cable must be installed at each end of the FICON (FCVmode) link. See 6.13, FICON (FCV) MCP Cables on page 82 and 6.14, ModeConditioner Patch (MCP) Cables on page 83 for more details.

1.8 Hardware Components (2)

This diagram describes the function of the remainder of the critical hardwarecomponents.

Spare Ports Card

The spare ESCON ports can only be used when a standard ESCON port isswapped for the spare port. It does not increase the total number of activeconnections available in the director. The fiber cable receptacles in the spare

MXC/MXS Cards

The three-card Matrix Controller and Matrix Switch set makes decisions ondynamic connection requests. It also provides for connection paths between portsspecified by port attributes defined in the active matrix configuration.

TKRG Controller Adapter Card

This card provides a port to connect the Director to a 4/16 Mbps Token-RingLocal Area Network (LAN) for access by a console on the LAN. The card alsocontains an RS-232-D asynchronous serial port for connecting a maintenanceterminal. The maintenance terminal port is intended for use by servicerepresentatives and allows access to 9032-5 maintenance utilities and functions.

Power Supplies

The power supplies provide DC power to the ESCON Director. The operating loadis shared by both power supplies until one fails. The operating power supply thenhandles the full power load.

This differs from the operation of the Enhanced Availability Features, where thesecondary component is a backup component and is unused until a failure isdetected in the primary component.

Cooling Fan Assemblies

Four fans provide cooling for the Director's internal components. The four fans arehoused in two assemblies, each containing two fans. The ESCON Director canoperate with any two of the four fans being operational. If three fans becomeinoperative the ESCON Director will power off after 10-20 minutes.Chapter 1. 9032-5 ESCON Director Introduction 11

1.9 Port Card Layout

The ESCON port cards in the 9032-5 are installed in four quadrants. QuadrantsA, B and C support up to eight ESCON port cards. Each ESCON port cardcontains 8 ESCON ports for a maximum of 64 ports per quadrant for quadrants A,B and C. Quadrant D supports only 7 port cards plus the spare ports card, so itsupports a maximum of 56 standard ESCON ports plus 4 spare ESCON ports.

Up to 16 FICON Bridge port cards can be installed in the 9032-5. They can beinstalled in any port card location in any of the quadrants. However they arerecommended to be installed in the locations shown in 1.10, FICON Bridge CardLayout on page 13.

The above table shows the port addresses assigned to each quadrant. In a9032-5 without the full complement of ESCON port cards, quadrant A will be filledfirst, followed by quadrant B, then C, and finally, D. This means that the defaultESCON port addresses will be contiguous even when the 9032-5 is not fullypopulated with port cards.

The spare ESCON ports card will always be installed in the last position inquadrant D regardless of the total number of ESCON port cards installed.

There are no FICON Bridge spare ports available as a 9032-5 feature code. If aspare FICON Bridge port is required, it should be ordered and installed as anormal FICON Bridge card (up to a maximum of 16).Each quadrant is a potential failure boundary and this should be taken intoconsideration when designing the ESCON Director configuration. For maximum

This diagram shows both the recommended port slot locations for the installationof the FICON Bridge port cards and the sequence of installation. The portaddresses shown are for a 9032-5 ESCON Director using the standard defaultport address assignment.

As the FICON Bridge port card only has one port, only the first port addressassigned to the port slot is used. The other 7 port addresses assigned to the portslot are unused.

1.11 Logical Partitioning

This diagram summarizes the logical partitioning capability of the 9032-5.

Logical partitioning allows an administrator to create port level access control thatis unique to each defined operator. This capability allows operators to access onlythe ports that they are authorized to use and restricts unauthorized operatorsfrom changing the port connectivity of any single device or set of devices undercontrol of the ESCON Director. This feature offers increased security andmaximizes the flexibility of the system configuration. Port authorization isactivated as soon as a user ID with limited port access is defined.

There are no restrictions on the allocation of ports to a Logical Partition. Thelogical partition setup can be changed at any time by a user with administratorauthority.

Some examples of situations where logical partitioning could be used are: A Service Bureau manages a mainframe site that processes data for several

businesses. Each business provides its own operations staff. The businessesneed to be able to make alterations to the ESCON Director configuration butthe Service Bureau needs to ensure that these changes cannot impact otherclients. Logical partitioning allows the Service Bureau to restrict the authorityof each of the operators at port level. This removes the possibility of anoperator inadvertently altering the connectivity attributes of a port outside theauthorized logical partition.

A test group and a production group share the use of a mainframe andESCON Directors but do not share other control units. The production control

IBM 9032 Model 5 ESCON DirectorLogical Partitioning

Logical partitioning allows the 9032-5 to be operatedsecurely as several separate ESCON DirectorsA logical partition can be:

As small as 1 port to as large as 248 contiguous ornon-contiguous ports in any increment or physical locationA different size from any other logical partitionMade up of dedicated or shared portsEasily implemented and modified

Some suitable environments for this feature may be:A service bureau managing systems for several clients butrequiring operational isolationA test system sharing ESCON directors with a productionenvironment


units can be protected from impact by the actions of the test group if theproduction control unit ports and unshared channel ports are excluded fromthe test group's partition. The production group can maintain control of theentire switch by allowing all ports to be part of the production logical partition.

1.12 Logical Partitioning Examples

This diagram shows an example of the ESCON Director matrix with logicalpartitioning active.

In this case the user is a printer operator who needs to reconfigure the printersbetween 2 different systems. Logical partitioning has been set up to allow theoperator to alter only the ports associated with the printers. The ports that theprinter operator is able to alter are in the unshaded areas and are indicated byarrows in the left margin. When port authorization is active the Operator ID of thecurrent user is displayed in the status window at the bottom of the matrix window.

This operator is not able to change attributes for any of the ports in the shadedpart of the matrix. The information in these areas is still visible and available forreference but it is not alterable.

1.13 Concurrent Maintenance Capability

This table shows the non-disruptive maintenance and upgrade capability of the9032-5.

All 9032-5 upgrade activity can be performed without disruption to the operationof the Director. Many of the major hardware components can also be replacedwhile the director continues to operate, particularly with the Enhanced AvailabilityFeatures installed.

Even with all of the Enhanced Availability Features installed, some 9032-5 partscannot be replaced while the Director is operational. We recommend that a highavailability I/O configuration should include at least two ESCON Directors toeliminate these single points of failure at the Director level.

Chapter 2. Installation Planning

This chapter describes the preparation required for the installation of a 9032-5ESCON Director.

There are many factors to be considered, including: Physical placement and environment requirements Console support requirements Fiber cabling infrastructure and strategy Software support requirements ESCON Director definition Configuration planning and definition

Each of these requirements is discussed in this chapter.


Installation Planning


2.1 Environmental Specifications

This diagram shows some of the basic environmental specifications for the9032-5 ESCON Director.

The 9032-5 has the same footprint as the 9032-3 but is significantly taller. Likethe 9032-3, service clearance is required at the front and back only, so Directorscan be installed in a row. Although there is no service clearance required at thetop of the 9032-5, the area must be kept clear to permit airflow.

The 9032-5 has dual power supplies as a standard feature. In order to takemaximum advantage of this availability feature the two power inputs should besourced from dedicated circuits on separate distribution boards and wherepossible, separate UPS components.

This is not a comprehensive list of environmental specifications. For moredetailed information refer to IBM System/360, System/370, 4300, 9370Processors Input/Output Equipment Installation Manual - Physical Planning -GC22-7064.

HMC. Via an orderable feature code to install the ESCD application on a customer

provided PC.

For full details of the console configuration and connectivity requirements seeChapter 3, 9032-5 Console on page 37.

IP Addresses

Depending on the chosen console configuration there may be a requirement toassign some TCP/IP addresses for the Director and the console. If the Directorand console are to be attached to a dedicated LAN, then the default IP addressesmay be acceptable for the installation. The default addresses are 1.1.1.x for theESCON Director and 1.1.1.1 for the IBM-supplied ESCON Director console. Ifthese addresses are not acceptable, the network administrator will need to assignnew IP addresses.

The number of addresses required depends on whether a secondary console isto be used and whether that console is to be used as a backup or a replacement

console. If the second console is a replacement console an additional IP addresswill not be required because the second console will use the same IP address asthe primary. If the second console is a backup console (with LAN attachment) itwill require its own IP address.

LAN Cabling

Prior to installation, consideration should be given to the LAN cablingrequirements.

If the ESCON Director and console are to be attached to an existing LAN thenMAU ports must be available. If addition MAU ports are required, a MAU can beordered with the ESCON Director by specifying Feature Code 5400.

If the MAU ports are not in close proximity to the Director and console, additionalLAN cables will also be required. The LAN cables supplied with the ESCONDirector have D shell connectors at the Director end of the cable and an IBMType-1 LAN connector at the other end. This type of connector may not becompatible with existing LAN infrastructure so adapters may be required.

Remote Access

DCAF remote access may be provided either via the LAN or via a telephoneconnection and modem.

If DCAF access is to be provided via a modem, it will be necessary to ensure thatan appropriate modem is available and that telephone access is available in closeproximity to the console.20 IBM ESCON Director 9032-5 Presentation

2.3 Fiber Cabling Considerations

This diagram shows some of the fiber cabling considerations when installing a9032-5.

The amount of cable required for routing inside the director for a 9032-5 issignificantly more than that required for the previous models. This may lead tosome difficulties if the 9032-5 is to replace an earlier model. The existing cablesmay not be long enough to reach many of the ports in the new ESCON Director.This should also be taken into consideration when jumper cables are installed inpreparation for the 9032-5 install.

A fully populated 9032-5 may have up to 248 ESCON jumper cables connected toits ports. This volume of cables can be cumbersome and can even be damaged ifappropriate cable routing and strain relief is not used.

Because of the volume of jumper cables required in a fully populated switch, the9032-5 is a good candidate for the use of trunk cables.

The 9032-5 has the added advantage of supporting the IBM Fiber Optic TransportServices (FTS) Direct Attach Feature. The FTS is discussed in more detail in thefollowing sections.

IBM 9032 Model 5 ESCON DirectorFiber Cabling Considerations

Plan for 2.8 meters of fiber cable inside the Director toprovide for cable routing

This is more than was required for previous 9032 modelsWhen the 9032-5 is a straight replacement for a previous 9032model, many existing fiber cables may be too short

This requirement was the same for previous 9032 modelsFollow a logical plan for routing cables

Spread across 3 access/cable restraint areasUse the strain relief provided to avoid cable and port card damage

Consider direct attach trunking options9032-5 supports FTS Direct Attach


2.4 Fiber Optic Transport Services (FTS) Direct Attach

FTS is a well-established fiber trunking system, and consists of a FTS trunkingsystem, FTS zone cabinets, FTS central cabinets and standard IBM ESCONjumper cables.It utilizes the zone and central cabinet concept. Components are directly attachedto zone cabinets by jumper cables. These connections are propagated to acentral cabinet via a trunk.

The advantage of the Direct Attach feature is that it allows the ESCON Directorports to be trunked to a central cabinet without the need for an intervening zonecabinet. The Direct Attach feature is also supported on most of IBM's processorsso it is now possible to trunk directly from a processor to an ESCON Directorwithout the need for zone or central cabinets.

The diagrams which follow illustrate this feature in more detail.

IBM 9032 Model 5 ESCON DirectorFTS Direct AttachIBM Fiber Transport Services (FTS) Direct Attach

FTS-III Direct Attach fiber optic trunk cables contain groups of 12fibers that support 6 ESCON channels (62.5 micron fibers)The trunk cables connect to harnesses which convert the trunkconnectors into groups of 6 IBM duplex connectorsThe trunk cables are run inside the 9032-5 and plug to harnesses atthe rear of the machineThe harnesses plug into the individual ESCON fiber optic ports(ESCD ESCON ports or S/390 processor ESCON channel ports)

Eliminates the need for zone distribution cabinets at theESCON Directors (and S/390 Processors)

ESCON Director ports can be trunked directly to a central cabinetReduces the requirement for central distribution cabinets

ESCON Director ports can be trunked directly to the Direct Attachfeature on S/390 processors


2.5 Trunking Options

These diagrams show examples of commonly used fiber cabling methods.

Throughout this series of diagrams, the aim is to connect six ESCON channelsfrom the processor on the right hand side, through the switch and to the controlunits on the left hand side.

The first example is a simple configuration using no trunk cables. Six jumpercables connect the processor to the ESCON Director and another six jumpercables connect the ESCON Director to the control units.

This is a suitable configuration where short distances are involved and where theconfiguration is stable. If the configuration changes frequently the workload dueto the cabling change could become a concern.

The second example shows a fully trunked configuration. Processors, ESCONDirectors and control units are all attached to zone cabinets. The Zone cabinetsare attached via trunks to central cabinets. The connections betweencomponents are made using jumper cables at the central cabinets.This is a suitable environment where extended distances are involved or wherefrequent reconfigurations, involving physical recabling, is required.

2.6 FTS Direct Attach Trunking Options (1)

This diagram shows some examples of the use of FTS Direct Attach. Theillustrated configurations achieve exactly the same connectivity as the previousexamples.

The first example shows the use of FTS Direct Attach at the ESCON Director.This removes the requirement for the ESCON Director ports to be cabled to azone cabinet. They are trunked directly to a central cabinet.

This is a suitable environment where extended distances are involved or wherefrequent reconfiguration, involving physical recabling, is required. Thisconfiguration offers exactly the same flexibility for reconfiguration as the fullytrunked example on the previous diagram but with reduced connections andcomplexity.

The second example shows the use of the FTS Direct Attach feature incombination with the same feature on a processor. This allows the processor tobe trunked directly to the ESCON director rather than via zone and centralcabinets. Full flexibility for the reconfiguration of control unit ports is maintained.

In some environments a combination of direct processor trunking and trunking viaa cabinet would be used. This allows more flexibility for reconfiguration,particularly if direct connections between processors and control units arerequired.

In most environments, however, the majority of CHPIDs will be attached toESCON Directors so the Direct Attach feature is of significant value.

There are many different central cabinet configurations possible. This diagramshows the use of two different sets of central cabinets.

In most cases the paths from the S/390 processor to the ESCON-attached controlunits should be routed through at least 2 ESCON Directors.

2.9 Supported Software Levels

This table shows the minimum level and release requirements for support of the9032-5.

All of the major IBM operating systems are supported.Also included in this table are the optional OS/390 products for support of theESCON Director environment. These are ESCON Manager and SystemAutomation for OS/390.

ESCON Manager

The IBM Enterprise Systems Connection Manager (ESCON Manager) is alicensed program (Program Number 5688-008) that provides host control to helpmanage connectivity within a computer facility.

Release 3 of ESCON Manager is designed to run on MVS/ESA 5.1 andsubsequent releases of that host operating system. With the application of theresolution to Authorized Problem Analysis Report (APAR) PN51474, however,Release 3 can run on MVS 4.2 and 4.3.Therefore, Release 3 can provide aunified system image that includes hosts on any of these MVS/ESA levels.

2.11 ESCON Manager - System Automation for OS/390

In any large, multisystem computing facility, understanding and controllingconnectivity is a complex task. For even a minor system change, you may needmore than definition files to understand whether two objects have the correctchain of connections through channels, switches, control units, and devices.Assistance by operations personnel may be needed to complete the propersequence of actions, especially if the task at hand involves problem determinationprocedures or "disaster" recovery actions.

ESCON Manager is a systems management product that provides a broad set ofconfiguration information and control functions to help make these tasks relativelysimple. It also ensures system integrity by taking into account the perspectives ofmultiple systems. One ESCON Manager communicates with other ESCONManagers and with other computer facilities to coordinate and manageconnectivity changes.

This foil describes some of the advantages of ESCON Manager. ESCONManager can:

Provide a unified system image Provide a single point of control Simplify or eliminate some planner and operator tasks Provide a means to automate connectivity changes to a dynamic switch, such

as an ESCON Director Reduce system problems caused by human error

2.12 9032-5 Port Definition - HCD Support

The installed 9032-5 port addresses should be defined as being installed usingHCD when being supported by OS/390.

For ESCON installed ports, define them in a contiguous group of 8 ports.

For a FICON Bridge port, only one port is defined in a group of 8 port addressesthat are assigned to the port slot that the FICON Bridge card is installed in. Theport address for the FICON Bridge port will be modulo 8 minus 4. The other 7 portaddresses assigned to the port slot should be defined as not installed.

The example in this diagram shows both ESCON installed ports (1C to 23) and aFICON Bridge installed port (24).

2.13 9032-5 I/O Definition

The ESCON Director, like any other device in the I/O configuration, should bedefined in the IODF. This allows the ESCON Director to present errors against itsdevice number, to attached operating systems. It also provides a means forESCON Manager to communicate with the Director.

It is possible for the ESCON Director to be used to provide connectivity without itsCUP (Control Unit Port) device being defined to the operating system, but this isnot recommended.

There should be at least two paths defined to access the ESCON Director (CUP).These paths should be attached to different quadrants or different port cards toeliminate the quadrant and the port card as single points of failure forcommunication with the Director CUP by the operating system.

Channel activity for communication with the ESCON Director is usually extremelylow. If ESCON Manager is not used there is virtually no channel activity, just thevery occasional error report. This means that the ESCON Director can sharepaths with other I/O devices connected though the Director without adverselyimpacting their performance. When the ESCON Director control unit is defined,the destination link address for all paths must be FE. This is the port addressassigned to the Control Unit Port (CUP). The CUP is a logical port used forcommunication with the Director.

Like many other ESCON devices, the unit address for the ESCON Director mustbe set to 00. If this parameter is not specified the unit address will default to thelast 2 digits of the device number. The unit address is specified in both the control

2.16 ESCON Configuration Guidelines

So far, the discussion has centered around the ESCON Director and itsdefinitions and requirements. The ESCON Director is likely to be a criticalcomponent in any system and it is important to ensure that it is used as effectivelyas possible.

This diagram shows some guidelines that should be followed when deciding on asuitable ESCON Director configuration. The aim of these guidelines is to reducethe impact to operating systems if a failure occurs in a Director or any componentof a Director.

The ESCON Director port cards are divided into quadrants. Each quadrantrepresents a potential failure boundary. Spreading connections from the samesystem or from the same control unit across multiple quadrants reduces theimpact of a failure affecting a quadrant.

Note that the number of ports on a ESCON port card in the 9032-5 is eight, andfor a FICON Bridge card one port address is used. Eight ports are assigned to theport card location that the FICON Bridge card is installed in, but only one portaddress is used. The other seven port addresses are not useable.There are fourESCON ports on a ESCON port card in the previous 9032 and 9033 models. TheESCON port assignment methods used when designing a 9032-3 configurationmay not be suitable when designing a 9032-5 configuration. For example, in a9032-3 environment the ESCON ports assigned to a DASD subsystem may be 84and 88. This is not a suitable assignment of ports in a 9032-5 because theseESCON ports are on the same ESCON port card.

IBM 9032 Model 5 ESCON DirectorESCON Configuration Guidelines

Provide redundancy at the ESCON Director level:Spread connections from the same system and from the samecontrol unit across multiple ESCON Directors

Provide redundancy at the ESCON Director quadrant level:Spread connections from the same system and from the samecontrol unit across multiple quadrants in the ESCON Director

Provide redundancy at the ESCON Director port card level:Spread connections from the same system or from the same controlunit across as many port cards as possible

To reduce the impact of an ESCON port card failure:Try and attach channels to the a port on the same port card as theirdestination ports

Prohibit connections that are not requiredReduces overhead in recoverySimplifies problem determination


The final recommendation takes into consideration the planned connectivitybetween channel and control unit ports. Where possible, channel and control unitports that communicate with each other should be supported by the same portcard. This will not always be possible because each port is likely to communicatewith several other ports. If this recommendation is followed the number ofconnections affected by a port card failure can be significantly reduced.

ESCON ports that are not intended to communicate with each other should be setto a Prohibit connection. This reduces overhead in recovery processing and insome circumstances, simplifies problem determination.

2.17 ESCON and FICON I/O Definition Guidelines

This diagram lists some general guidelines for I/O definition in an ESCONEnvironment.

HCD does validity checking based on the information provided by the user.

When defining CHPIDs in HCD it is necessary to enter a dynamic switch ID butthe switch entry port is not a required parameter for ESCON channels. If thisinformation is entered the value of HCD's validity checking is maximized. HCD isable to verify that you do not intend to use the same port address on the sameswitch twice. This also serves as a simple way to manage switch port allocation.

HCM users don't have to worry about managing Director port allocation - HCM'sgraphic interface does it all without the need to input additional information.

Chapter 3. 9032-5 Console

This chapter describes the requirements for setting up the ESCON DirectorConsole. Hardware and software requirements and configuration options arediscussed in detail. Remote console access to the 9032-5 is also included in thischapter.


Consoles


3.1 Console Introduction

Console Introduction

The 9032-5 is supported by the ESCON Director Console Application which runson a PC attached to a Token-Ring LAN.

The console can be used to monitor and control up to 16 ESCON Directors.Supported Directors are the 9032-3, 9033-4 and 9032-5.

The list shown in the diagram shows some of the functions for which the consoleis required.

The ESCON Director console is not required for continuous operation of theDirectors, nor is it required to recover after a Director is powered off/on. Onematrix configuration file, the IPL file, is stored in the CTP card. If defaults areaccepted (Active = Saved option selected), this file will be the most recentlyactivated matrix configuration. After power off/on, the Director operation will berestored and the matrix configuration stored in the CTP card will be active.

IBM recommends that the Director Console should always be attached to theDirector:

To maintain copies of matrix configuration files To provide error reporting and log functions To provide current status of the entire Director network

IBM 9032 Model 5 ESCON DirectorConsole IntroductionThe 9032-5 is supported by a WIN-OS/2-based ESCDConsole Application running on a Token-Ring attached PCThe console can monitor and control up to 16 ESCDsThe ESCON Director Console is required to:

Install the ESCON DirectorAccess LogsPerform service actionsPerform upgrades and LIC changesSave configuration matrix files independent of hostsManage ESCDs configurations (if ESCM is not installed)

Console is required for changes to be saved to disk even when changesare made using ESCM

The 9032-5 may have a session with only one consoleA backup console may be available but if connectivity to the 9032 isavailable from the prime Console, the Console Application must firstbe shut down on the prime console


Copies of all required matrix configurations should be stored on the ESCDconsole disk. This facilitates recovery in the event of a failure in the CTP card.

The console is not required for activating matrix configuration changes from thehost using System Automation for OS/390 (SA/MVS) or ESCON Manager. Theuse of ESCON Manager reduces the requirement for physical access to theESCON Director console, but it does not reduce the requirement for the consoleto be available. The console is required if these matrix configuration changes areto be saved to the HDD in the console PC.

For maximum availability, a backup console should be maintained if the Directorsprovide access to critical system or application data. There are two options forconfiguring the backup console:1. Maintain a PC with all current configuration files but without attachment to the

LAN. This PC may have the same IP address as the primary Director Console.In the event of a failure of the primary console, its LAN connection can betransferred to the secondary console. This is referred to as a replacementconsole.

2. Maintain a PC with all current configuration files and LAN attachment. Anadditional unique IP address will be required for this PC. The ESCON DirectorConsole Application on the backup PC must not be active. In the event of afailure of the primary console, the ESCON Director Console Application canbe started on the secondary console. This is referred to as a backup console.

This diagram lists the minimum hardware and software requirements for aconsole supporting the ESCD Console Application for a 9032-5.

These requirements are not the same as the requirements for 9032-3 and9033-4. In most cases a console currently used for support of 9032-3 and/or9033-4 will not be suitable for use with the 9032-5.

3.3 Console Platforms

This diagram shows the platforms available for supporting the 9032-5 ESCONDirector Console Application. These are shown in order of preference. Aspreviously discussed, the ESCON Director Console Application should beavailable at all times. Although the HMC supports the ESCD Console Application,it is not a recommended platform for the following reasons:

The HMC is used as an alerting tool. This function is effectively disabled whilean operator is using the ESCD application.

HMC operator functions are unavailable while an operator is using the ESCDApplication.

The ESCD Console Application must not be included in the HMCSTARTUP.CMD file. If the HMC is re-booted for any reason, the ESCDConsole Application will not be restarted without operator intervention.

The IBM-supplied PC is preferable to the customer-supplied PC because it ispre-configured with all required hardware and software. If a customer-supplied

IBM strongly recommends using the IBM-supplied PCDedicated PC is more suitable because of the critical nature ofthe applicationIBM supplied PC is pre-configured with all required hardware andsoftware


PC is used, it should be dedicated as the ESCD console, with no additionalapplications installed.

3.4 Console Configurations

The LAN to which the ESCON Director is connected may be dedicated, private orpublic.

A dedicated LAN supports only the ESCON Directors and their consoles. It doesnot have connectivity to any other network components or hardware. Because noother connectivity is provided the IP addresses of the console and the ESCONDirectors need only be unique with respect to each other.

Private LAN refers to a LAN with tightly controlled access such as the typicalmachine room LAN supporting S/390 Servers, HMCs and other criticalequipment.

Public LAN refers to the typical local LAN used to support all users in an area.The security on a public LAN is generally less restrictive and the traffic is lesspredictable.

It is possible for the ESCON Director and its console to be attached to differentLANs but still communicate through a bridge. The bridge must be configured toallow TCP/IP protocol to flow. The 9032-5 does not support IP routing so theconnection between an ESCON Director on one LAN and the console on anothercannot involve routing.

IBM 9032 Model 5 ESCON DirectorConsole ConfigurationsThe ESCON Director Console can be located anywhereup to the limit of the installed token ringThe console and 9032-5 may be attached to a dedicated,private or a public LANIP routing is not supported by the 9032-5If the console and the 9032-5 are attached to differentLANs, direct communication can be established througha bridge

The bridge must be configured to allow TCP/IP protocol to passthrough

Remote access to the ESCON Director ConsoleApplication may be provided through DCAF via a LANor modem connection

Copyright IBM Corporation, 1999Chapter 3. 9032-5 Console 41

By using Distributed Console Access Facility (DCAF) Controller software, it ispossible to initiate a remote session with the ESCD console via a LAN connectionor a modem. The remote session has all the command privileges of the targetconsole. DCAF network protocol may be TCP/IP (with routing) or SNA.Before a remote DCAF session can be established, the ESCON Director ConsoleApplication must be set up to run in a WIN-OS/2 window rather than in WIN-OS/2full-screen mode. WIN-OS/2 full-screen mode is not supported by DCAF.

3.5 Some Supported Console Configurations

This diagram shows some of the supported 9032-5 console configurations. Itdoes not cover all of the possible combinations and variations. In all cases remotesupport is available, either via the corporate LAN or via a modem.

The diagram on the left-hand side shows the Director and the console attached toa dedicated LAN. No other network equipment has access to this LAN. In thisexample, remote access is provided via a modem.

This is the simplest console configuration. It is secure and easy to set up becauseIP addresses can remain at their default values.

The configuration in the center of the page shows a private machine room LANwith the ESCON Director Console Application residing on an HMC. In this case,the HMC can be remotely accessed by DCAF via the corporate LAN. Other users

of the machine room LAN may include S/390 Servers, HMCs, Sysplex Timers andSysplex Timer consoles.

This configuration is also secure and provides for remote access, but the use ofthe HMC to support the ESCD Console Application is a disadvantage, aspreviously discussed.

The configuration on the right-hand side is a slight variation on the previousconfiguration. Again, the machine room LAN is used but in this case, the ESCDConsole application is supported by a dedicated PC rather than the HMC. In thiscase the Machine Room LAN cannot be accessed from the Corporate LAN, soDCAF access is provided via a modem connection.

The use of a dedicated console is preferable to the use of the HMC.

3.6 More Supported Console Configurations

The console configuration on the left-hand side shows bridged LANs. TheESCON Director and its console are attached to different LANs and the LANs areconnected through a bridge.

Using a bridge in this way is not recommended. Problem determination is moredifficult because failures in one LAN segment can impact the other.

The configuration on the right hand side shows the ESCON D
