In most cases the reason for the installation of this module is to convert a VAX 7000 system into a DEC 7000 system. To support the DSSI subsys­ tem already installed, you will need to take out the KFMSA adapter (and associated hardware) and install the KFMSB adapter (and associated hardware) in its place. If this is a new installation of a DSSI bus in a DEC system, review the background information in this chapter and see the manuals referenced for more information. Sections in this chapter include: · System Configuration · KFMSB Adapter · Contents of KFMSB Kits · DSSI Terminology and Configurations · DSSI Installation Overview · Cabling and Setting Node IDs 1­2 Preparation 1.1 System Configuration To upgrade a VAX 7000 system with DSSI buses to a DEC 7000 sys­ tem that also uses the DSSI buses requires the removal of the KFMSA adapter from the XMI card cage and the installation of the KFMSB adapter. Figure 1­1 DEC 7000 Architecture Preparation 1­3 If you already have a DSSI subsystem installed, you only need to do the following: 1. Remove the KFMSA adapter and the cabling from the XMI backplane to the bulkhead and remove the bulkhead panel. 2. Install the KFMSB adapter and the cabling from the XMI backplane to the bulkhead and install the bulkhead panel. 3. Run LFU to ensure that you have the latest firmware on the modules. If you do not already have a DSSI subsystem installed, you will need to in­ stall a BA654 DSSI disk PIU for in­cabinet disks. SF or SW cabinets can be used for external disks. For more information, see the books listed in Table 1­6. 1­4 Preparation 1.2 KFMSB Adapter DEC 7000 systems support DSSI using the KFMSB adapter in­ stalled in the XMI card cage. Each KFMSB supports two DSSI buses. The KFMSB has a diagnostic LED and reports status to the system self­test display. Figure 1­2 KFMSB LED Preparation 1­5 Each KFMSB module has two ports, and each port supports a DSSI bus. Each DSSI bus can have up to eight nodes, with node numbers from 0 to 7. The DSSI node IDs for both ports are factory set to node 7. Of the eight nodes configured between any two terminators on a DSSI bus, one to four nodes can be DSSI host adapters. The remaining nodes can be RF disk or TF tape integrated storage elements (ISEs) or HSDxx DSSI­to­SCSI stor­ age adapters. The buses are configured physically by the cable. The cable from XMI backplane section D (upper section) is designated as bus 1, and the cable from section E is bus 0. These cables connect to the XMI bulkhead. The KFMSB runs a self­test during power­up and the console displays re­ sults on the system self­test display (see Section 3.1). The yellow LED on the KFMSB lights to indicate that self­test passed. 1­6 Preparation 1.3 Contents of KFMSB Kits Each kit contains an XMI module. The upgrade kit also includes the CK­KFMSB­LB cabinet kit. Table 1­1 KFMSB Kit Contents Table 1­2 KFMSB Cabinet Kit Contents Option Number Description KFMSB­AA Includes the KFMSB XMI module that supports DSSI systems in DEC 7000 and DEC 10000 (AXP) systems; also includes this installation guide (EK­KFMSB­IN). KFMSB­UA The upgrade kit includes the KFMSB XMI module, the installation guide, and the KFMSB cabinet kit. Option Number Part Number Description CK­KFMSB­LB 17­03451­01 XMI backplane to bulkhead cable; includes the I/O panel connector. 12­31281­01 Four bus terminators. Preparation 1­7 There are two kits: KFMSB­AA, which is the kit to use if you are install­ ing a new system or adding a KFMSB to an existing system, and KFMSB­ UA, which is an upgrade kit. The upgrade kit includes the cabinet kit; the other kit does not. You must order the KFMSB cabinet kit (CK­KFMSB­ LB) for use with the KFMSB­AA option. If an upgrade kit is being in­ stalled, you must return the KFMSA module removed from the VAX sys­ tem. See Section 2.4. Cables external to the XMI PIU must be ordered separately.

Contains two cables (BC21Q­09 and BC21R­5L). One kit is required for each DSSI bus used (maxi­ mum of two kits per KFMSB). 1­8 Preparation 1.4 DSSI Terminology and Configurations Figure 1­3 shows a single­host configuration consisting of a DEC 7000 system connected to ISEs on a DSSI bus. The ISEs can be in the system cabinet or in expander cabinets. Multi­host systems can also be configured. Figure 1­3 Single­Host System DSSI can be implemented in single­ or multi­host mode. In single­host, one system has access to integrated storage elements (ISEs) across the DSSI storage bus. In multi­host configurations, the systems remain func­ tionally independent while their common DSSI storage bus, together with VMScluster software, makes ISEs available to each system, providing mul­ tiple data paths for access to ISEs. The system cabinet can have up to two DSSI PIUs, and an expander cabi­ net can have up to six PIUs. SF and SW cabinets can also be used for disks. Preparation 1­9 Table 1­5 DSSI Terminology Term Definition Control panel An enclosure interface that allows remote control of DSSI node ID selection and ISE operating status. DSSI Digital Storage System Interconnect. A DSA­ based storage interconnect used by the KFMSB adapter and the RF and TF series integrated storage elements to transfer data and to commu­ nicate with each other. Single­host Storage configuration where ISEs are connected to only one host system. Multi­host Storage configuration where ISEs are shared be­ tween two, three, or four DSSI adapters on a DSSI subsystem with multiple host systems. ISE Integrated storage element. On the DSSI storage bus, all RF and TF storage devices are ISEs. MSCP Mass storage control protocol. An application layer protocol used by the host to perform disk I/O operations and I/O control functions. Node name A 6­character (maximum) value assigned to each ISE. The node name of each ISE must be unique across the system topology. Split­bus A mode of operation where the bus servicing the ISEs in the system cabinet is different from the bus servicing the ISEs in the expander cabinets. Through­bus A mode of operation where all ISEs are on the same DSSI bus. 1­10 Preparation 1.5 DSSI Installation Overview Table 1­6 lists books that provide detailed installation instructions for DSSI systems. Table 1­7 provides an overview of installation. Steps include cabling, terminating the DSSI bus, and setting node IDs for the bus.

Preparation 1­11 Table 1­7 DSSI Installation Location Single­Host Configuration Multi­Host Configuration Bus Termination System and expander cabinet Install termination on each unused connector as necessary. Node ID Settings KFMSB No change. Leave at factory setting of node ID 7. Set second host node ID to 6, a third host to 5, and a fourth host to 4. ISEs No change. Should be set correctly at factory. Tapes are set to node ID 0; disks are normally set starting at node ID 1 to 6. Adding Hosts to Existing DSSI Subsystems New and original hosts Reconfigure DSSI storage bus, setting node IDs, termination, and possibly changing split­bus in SF cabinets. 1­12 Preparation 1.6 Cabling and Setting Node IDs A DSSI bus has up to eight nodes, each with a unique node num­ ber. Each KFMSB module has two separate DSSI buses, called bus 0 and bus 1, cabled from the XMI backplane to the bulkhead. The external DSSI cables connect the bulkhead to the DSSI PIU. Each KFMSB module has two separate DSSI buses cabled from XMI back­ plane sections D and E. The cable from section D is designated as bus 1, and the cable from section E is bus 0. The overall physical bus length is limited to 27 m (89 ft). One external DSSI cable is required for each bus connection between systems; two ca­ bles are required to connect two systems and an expander cabinet. Each bus must be terminated at both ends. See the DSSI VMScluster Installa­ tion and Troubleshooting Guide for instructions on where and how to in­ stall the terminators. The node IDs for KFMSB modules are factory set with both ports having the node ID of 7. KFMSB node IDs for single­host systems do not have to be changed. For a dual­host system, the second host system's KFMSB node ID must be set to 6. On a tri­host system, the third host system's KFMSB node ID must be set to 5. On a quad­host system, the fourth host system's KFMSB node ID must be set to 4. (Appendix A gives instructions for changing adapter node IDs.) You can set the DSSI node IDs for the ISEs using the switches on the disk PIU or with the cdp console command. Each bus presents a discrete set of registers to the host. For communication to occur, the host software must identify which DSSI bus is attached to which ISE. NOTE: The new ISE node IDs are not in effect until each device is turned off, then on (power­cycled). After power­cycling, the node IDs have been changed at the ISE level. When attaching the cables to a disk PIU: 1. For each populated bus, install one external cable to one of the KFMSB disk controller ports. Tighten the two screws that secure each cable to the XMI I/O bulkhead. 2. If the system has more than one KFMSB adapter, install additional DSSI cables, as above. 3. Install terminators where needed. Each bus must be terminated at both ends. Installing the Adapter 2­1 Chapter 2 Installing the Adapter This chapter tells how to install the KFMSB adapter into an XMI plug­in unit (PIU) in DEC 7000 systems. The following sections are in this chapter: · Installing the Adapter in the XMI Card Cage · Installing the Internal Cable · External Cabling and Termination · Module Return 2­2 Installing the Adapter 2.1 Installing the Adapter in the XMI Card Cage Choose the slot for the KFMSB adapter and install the adapter in the XMI card cage. Figure 2­1 Installing the KFMSB Adapter Installing the Adapter 2­3 To install the KFMSB adapter in the XMI card cage: 1. Perform an orderly shutdown of the operating system. 2. Turn the control panel keyswitch to Disable. 3. Open the front and rear cabinet doors. 4. Ground yourself to the cabinet with the antistatic wrist strap from the Electrical Safety Kit. 5. Remove the panel on the front of the XMI PIU by releasing the cap­ tive screws at the top of the panel. Check that no LEDs are lit on the XMI modules and that the XMI is not receiving power. 6. Determine the slot where you want the KFMSB to go. Raise the lever and hold it up until you remove or install the module in that slot. If you are replacing the KFMSA adapter (DSSI adapter on a VAX sys­ tem), remove that module and put it aside. Install the KFMSB module. 7. Replace the front panel of the XMI card cage. 2­4 Installing the Adapter 2.2 Installing the Internal Cable Install the cable that connects the XMI backplane to the bulkhead. The cable includes the bulkhead connector. Plug the connector cables into the appropriate segments of the XMI backplane. In­ stall terminators. Figure 2­2 Cabling the XMI Backplane Installing the Adapter 2­5 Installing the KFMSB adapter requires installing the CK­KFMSB­LB cabinet kit. The kit consists of a Y cable (17­03451­01) and an attached bulkhead connector panel. To install the cable assembly to the XMI bulkhead door: 1. Remove the cable door (a panel at the bottom of the cabinet) by releas­ ing the two captive screws at the top of the panel and lifting it off. 2. Lift the two spring­loaded pins on the bulkhead door and swing it open on its hinges. 3. Remove the flat plate over one of the openings in the I/O bulkhead. 4. If you are replacing the KFMSA module, you must remove its internal XMI cabling and the bulkhead panel. 5. Install the cable assembly using a Phillips screwdriver to fasten the four small screws that hold the plate to the bulkhead door. To install the connector cables in the XMI backplane: 1. Plug one end into segment D2 on the XMI backplane and the other into segment E2. Segment D is for channel 1 and segment E is for channel 0. The raised "notch" on one side of the cable connector goes to the right. 2. Route the cables through the cable hold­downs at the bottom of the PIU. 3. Refasten the I/O panel door at the bottom of the cabinet. NOTE: For multihost configurations, it is a good idea to keep the same scheme for the cable connections on the I/O panel: for example, left for channel 0, and right for channel 1. 2­6 Installing the Adapter 2.3 External Cabling and Termination You now reconnect the external DSSI cables from the XMI bulk­ head to the DSSI PIU. If this is a new DSSI installation, refer to the manuals listed in Table 1­6. Figure 2­3 Cabling to the DSSI PIU Installing the Adapter 2­7 If the DSSI subsystem is already installed, you can now reconnect the DSSI cable from the PIU. · Install the external DSSI cabling and terminate each bus at each end. Four terminators (12­31281­01) are included in the cable kit. · Close the cabinet doors. · Power up the system by turning the control panel keyswitch to Enable. 2­8 Installing the Adapter 2.4 Module Return Any KFMSA modules taken from an upgraded machine should be returned to the Returns Sort Center. These instructions for the return of modules apply to the U.S area only. Those installing upgrades in other areas should follow procedures for those countries. 1. Package the module removed from the system in the same container in which the new module was shipped. Be sure to remove the return address label from inside the box prior to packing. 2. Seal the container securely with packing tape. 3. Attach the return address label. Be sure to cover all previous shipping information with the label and/or packing tape. 4. Contact your district Customer Administration Services (CAS) repre­ sentative for a Return Authorization Number (RA number). CAS will need the Digital order number and customer name. CAS will arrange for pickup of this material. (If you do not know the district CAS rep­ resentative, contact the district sales office for instructions.) 5. Write the RA number on the return address label. Be sure this is leg­ ible. 6. Customers should be advised that they will be billed for modules not returned to Digital. 7. Send the package to the customer shipping area for pickup. 8. Digital customer service must fill out the LARS form as follows: (Fill in "X" with information from shipping paperwork and give the RA number.)

Place the Alpha AXP Systems Firmware Update CD­ROM in an InfoServer and do the following: 1 Type sho dev kzmsa at the console terminal to find the load device, the RRD42, on the system. 2 In Example A­1 the unit number for the RRD42 is shown as dkb400.4.1.3.0. 3 Using the unit number, boot the system load device. 4 For a DEC 7000 system, type the bootfile name as shown. The nn is the version number of the Alpha AXP firmware CD­ROM. 1 Type sho net at the console terminal to see if there is more than one DEMNA. 2 Boot from the first DEMNA (exa0), using the ­file option with the file name AXP7000_Vnn, supplying the correct version number. A­4 Using LFU A.2 Use Display Command to Check Configuration The LFU display command shows the system configuration, pro­ viding the device mnemonic you use to modify the KFMSB node number. Example A­3 LFU Display Command Function? display Name Type Rev Mnemonic FW Rev HW Rev LSB 0+ KN7AA (8001) 0000 kn7aa0 1.0 E04 5+ MS7AA (4000) 0000 ms7aa0 N/A A01 7+ MS7AA (4000) 0000 ms7aa1 N/A A01 8+ IOP (2000) 0002 iop0 N/A A C0 XMI xmi0 8+ DWLMA (102A) A5A6 dwlma0 N/A A B+ KZMSA (0C36) 5143 kzmsa0 4.3 F01 C+ KFMSB (0C31) 5143 kfmsb0 4.3 F01 E+ DEMNA (0C03) 060B demna0 6.8 Using LFU A­5 Use the LFU display command to find the device mnemonic for the KFMSB adapter that you want to modify. The display command is shown in Example A­3. A­6 Using LFU A.3 Use Modify to Change the DSSI Node Number The LFU modify command allows you to change the DSSI node number of a KFMSB adapter. Example A­4 LFU Modify Command Function? modify kfmsb0 1 kfmsb0 Channel 0 DSSI node ID: 07 Channel 1 DSSI node ID: 07 Do you wish to modify any of these parameters? [y/(n)] y 2 Channel 0 DSSI node ID: 07 Change? [y/(n)] y 3 Valid ID is a value from 0 to 7. Enter new DSSI node ID: 3 Channel 1 DSSI node ID: 07 Change? [y/(n)] y Valid ID is a value from 0 to 7. Enter new DSSI node ID: 6 Channel 0 DSSI node ID: 03 4 Channel 1 DSSI node ID: 06 Modify kfmsb0 with these parameter values? [y/(n)] y Function? exit 5 Using LFU A­7 To modify the DSSI node number for a KFMSB module: 1 Enter the modify command. The modify command displays the current settings for the parameters. 2 LFU asks if you wish to modify any parameters. Type y. 3 LFU displays each parameter and asks if you want to modify it. Press RETURN to accept the current setting; type y and RETURN to change the current setting. 4 LFU displays the new settings and asks if you want to modify the KFMSB with the settings you just provided. Type y and RETURN to modify the EEPROM in the KFMSB with the new values. (Note: Installing firmware updates with LFU does not affect the pa­ rameters you change here; they stay changed through the update.) 5 Exit LFU when you are done.
