contains up to eight linecards. The Memory Channel adapter in each system in the cluster is connected to the Memory Channel hub. One or two Memory Channel adapters can be used with T ruCluster Server .
The operating system disk (T ru64 UNIX disk) cannot be used as a clusterwide disk, a member boot disk, or as the quorum disk. Because the T ru64 UNIX operating system will be available on the first cl.
A member boot disk cannot contain one of the clusterwide root ( / ), /usr , and /var file systems. Also, a member boot disk cannot be used as the quorum disk. A member disk can contain more than the three required partitions. Y ou can move the swap partition off the member boot disk.

multiple BA356 storage units can be used on the same SCSI bus to allow more devices on the same bus. Figure 1 – 4 shows the configuration in Figure 1 – 3 with a second UltraSCSI BA356 storage unit that provides an additional seven disks for highly available applications.
1.6.3 T w o-Node Configurations with UltraSCSI BA356 Storage Units and Dual SCSI Buses By adding a second shared SCSI bus, you now have the capability to use the Logical Storage Manager (LSM) to mirror data disks, and the clusterwide /usr and /var file systems across SCSI buses.

6. Install signal converters in the StorageW orks enclosures, if applicable (see Chapter 3 and Chapter 9). 7. Connect storage to the shared SCSI buses. T erminate each bus. Use Y cables or trilink connectors where necessary (see Chapter 3 and Chapter 9).
2 Hard ware Requirements and Restrictions This chapter describes the hardware requirements and restrictions for a T ruCluster Server cluster . It includes lists of supported cables, trilink connectors, Y cables, and terminators. See the T ruCluster Server Software Product Description (SPD) for the latest information about supported hardware.
There are currently three versions of the Memory Channel product; Memory Channel 1, Memory Channel 1.5, and Memory Channel 2. The Memory Channel 1 and Memory Channel 1.5 products are very similar (the PCI adapter for both versions is the CCMAA module) and are generally referred to as MC1 throughout this manual.
• For AlphaServer 2000 systems, the B2111-AA module must be at Revision H or higher . For AlphaServer 2100 systems, the B2110-AA module must be at Revision L or higher .

termination and covers radial configurations with the DWZZH UltraSCSI hubs and non-UltraSCSI RAID array controllers. This chapter discusses the following topics: • Shared SCSI bus configuration requirements (Section 3.1) • SCSI bus performance (Section 3.
• All supported UltraSCSI host adapters support UltraSCSI disks at UltraSCSI speeds in UltraSCSI BA356 shelves, RA7000 or ESA10000 storage arrays (HSZ70 and HSZ80), or RA8000 or ESA12000 storage arrays (HSZ80 and HSG80).
3.2.1 SCSI Bus V er sus SCSI Bus Segments An UltraSCSI bus may be comprised of multiple UltraSCSI bus segments. Each UltraSCSI bus segment is comprised of electrical conductors that may be in a cable or a backplane, and cable or backplane connectors. Each UltraSCSI bus segment must have a terminator at each end of the bus segment.
connect devices that use different transmission methods, use a SCSI signal converter between the devices. The DS-BA35X-DA personality module is discussed in Section 9.1.2.2. See Section 9.1 for information about using the DWZZ* series of SCSI signal converters.
SCSI bus adapters have a default SCSI ID that you can change by using console commands or utilities. For example, a KZPSA adapter has an initial SCSI ID of 7. ______________________ Note _______________________ If you are using a DS-DWZZH-05 UltraSCSI hub with fair arbitration enabled, SCSI ID numbering will change (see Section 3.
T able 3 – 2: SCSI Bus Segment Length SCSI Bus Bus Speed Maxim um Cable Length Narrow , single-ended 5 MB/sec 6 meters Narrow , single-ended fast 10 MB/sec 3 meters Wide differential, fast 20 MB/sec.
Most devices have internal termination. For example, the UltraSCSI KZPBA-CB and the fast and wide KZPSA-BB host bus adapters have internal termination. When using a KZPBA-CB or KZPSA-BB with an UltraSCSI hub, ensure that the onboard termination resistor SIPs have not been removed.
3.6.1 Using a D WZZH UltraSCSI Hub in a Cluster Configuration The DS-DWZZH-03 and DS-DWZZH-05 UltraSCSI hubs are supported in a T ruCluster Server cluster .
• DS-DWZZH-03 and DS-DWZZH-05 UltraSCSI hubs may be housed in the same storage shelf with disk drives. T able 3 – 3 provides the supported configurations.
_____________________ Note _____________________ Dual power supplies are recommended for any BA356 shelf containing a DS-DWZZH-05 UltraSCSI hub in order to provide a higher level of availability between cluster member systems and storage. • The lower righthand device slot of the BA370 shelf within the RA7000 or ESA 10000 RAID array subsystems.

or SCSI bus failure, the host can redistribute the load to the surviving controller . In case of a controller failure, the surviving controller will handle all units. ______________________ Notes ______________________ Multiple-bus failover does not support device partitioning with the HSZ70 or HSZ80.
2. Attach the trilink with the terminator to the controller that you want to be on the end of the shared SCSI bus. Attach an H8861-AA VHDCI trilink connector to: • HSZ70 controller A and controller .

4 T ruCluster Server System Configuration Using UltraSCSI Hard ware This chapter describes how to prepare systems for a T ruCluster Server cluster , using UltraSCSI hardware and the preferred method of radial configuration, including how to connect devices to a shared SCSI bus for the T ruCluster Server product.
This is especially critical if you will install tape devices on the shared SCSI bus. W ith the exception of the TZ885, TZ887, TL890, TL891, and TL892, tape devices can only be installed at the end of a shared SCSI bus. These tape devices are the only supported tape devices that can be terminated externally .
• Number of shared SCSI buses and the storage on each shared bus Using shared SCSI buses increases storage availability . Y ou can connect 32 shared SCSI buses to a cluster member . Y ou can use any combination of KZPSA-BB, KZPBA-CB, or KGPSA-BC/CA host bus adapters.
T able 4 – 1: Planning Y our Configuration (cont.) T o increase: Y ou can: Disk availability Mirror disks across shared buses. Use a RAID array controller . Shared storage capacity Increase the number of shared buses. Use a RAID array controller . Increase disk size.
6. Copy the appropriate release notes to your system disk. In this example, obtain the firmware release notes for the AlphaServer DS20 from the V ersion 5.6 Alpha Firmware Update CD-ROM: # cp /mnt/doc/ds20_v56_fw_relnote.txt ds20-rel-notes 7. Unmount the CD-ROM drive: # umount /mnt 8.
______________________ Note _______________________ The KZPSA-BB can be used in any configuration in place of the KZPBA-CB. The use of the KZPSA-BB is not mentioned in this chapter because it is not UltraSCSI hardware, and it cannot operate at UltraSCSI speeds.

The DWZZH contains a differential to single-ended signal converter for each hub port (sometimes referred to as a DWZZA on a chip, or DOC chip). The single-ended sides are connected together to form an internal single-ended SCSI bus segment.
Y our storage shelves or RAID array subsystems should be set up before completing this portion of an installation. Use the steps in T able 4 – 3 to set up a KZPBA-CB for a T ruCluster Server cluster that uses radial connection to a DWZZH UltraSCSI hub.
T able 4 – 3: Installing the KZPBA-CB f or Radial Connection to a D WZZH UltraSCSI Hub (cont.) Step Action Refer to: _____________________ Notes _____________________ Ensure that the SCSI ID that you use is distinct from all other SCSI IDs on the same shared SCSI bus.

4.3.3.1 Displaying KZPBA-CB pk* or isp* Console En vironment V ariables T o determine the console environment variables to use, execute the show pk* and show isp* console commands. Example 4 – 5 shows the pk console environment variables for an AlphaServer DS20.
• on — T urns on both low 8 bits and high 8 bits • diff — Places the bus in differential mode The KZPBA-CB is a Qlogic ISP1040 module, and its termination is determined by the presence or absence of internal termination resistor SIPs RM1-RM8. Therefore, the pk*0_soft_term environment variable has no meaning and it may be ignored.
4.3.3.2 Setting the KZPBA-CB SCSI ID After you determine the console environment variables for the KZPBA-CBs on the shared SCSI bus, use the set console command to set the SCSI ID. For a T ruCluster Server cluster , you will most likely have to set the SCSI ID for all KZPBA-CB UltraSCSI adapters except one.

5 Setting Up the Memor y Channel Cluster Interconnect This chapter describes Memory Channel configuration restrictions, and describes how to set up the Memory Channel cluster interconnect, including setting up a Memory Channel hub, Memory Channel optical converter (MC2 only), and connecting link cables.
____________________ Note _____________________ If you are installing SCSI or network adapters, you may wish to complete all hardware installation before powering up the systems to run Memory Channel diagnostics.
If you are upgrading from virtual hub mode to standard hub mode (or from standard hub mode to virtual hub mode), be sure to change the jumpers on all Memory Channel adapters on the rail.
T able 5 – 2: MC2 Jumper Configuration (cont.) Jumper: Description: Example: VH0: Pins 2 to 3 12 3 VH1: None needed; store the jumper on pin 1 or pin 3 12 3 J3: W indow Size 512 MB: Pins 2 to 3 12 3.
T able 5 – 2: MC2 Jumper Configuration (cont.) Jumper: Description: Example: J10 and J11: Fiber Optics Mode Enable Fiber Off: Pins 1 to 2 3 2 1 Fiber On: Pins 2 to 3 pins 3 2 1 a Increases the maximum sustainable bandwidth for 8x00 systems. If the jumpers are in this position for other systems, the bandwidth is decreased.
If you are setting up a redundant Memory Channel configuration, install the second Memory Channel adapter right after installing the first Memory Channel adapter . Ensure that the jumpers are correct and are the same on both modules. After you install the Memory Channel adapter(s), replace the system panels unless you have more hardware to install.
For use with the MC2 CCMAB adapter , the hub must be placed within 4 or 10 meters (the length of the BN39B link cables) of each system. If fiber optics is used in conjunction with the MC2 adapter , the hub may be placed up to 31 meters from the systems.
5.5.1.1 Connecting MC1 or MC1.5 Link Cables in Vir tual Hub Mode For an MC1 virtual hub configuration (two nodes in the cluster), connect the BC12N-10 link cables between the Memory Channel adapters installed in each of the systems. _____________________ Caution _____________________ Be very careful when installing the link cables.
Figure 5 – 1: Connecting Memory Channel Adapters to Hubs Memory Channel hub 1 Memory Channel hub 2 System A Memory Channel adapters Linecards ZK-1197U-AI 5.
Gently push the cable ’ s connector into the receptacle, and then use the screws to pull the connector in tight. The connector must be tight to ensure a good ground contact. If you are setting up redundant interconnects, all Memory Channel adapters in a system must have the same jumper setting, either VH0 or VH1.
Now you need to: • Set the CCMLB linecard jumpers to support fiber optics • Connect the fiber optics cable to a CCMFB fiber optics converter module • Install the CCMFB fiber optics converter mod.
There are two console level Memory Channel diagnostics, mc_diag and mc_cable : • The mc_diag diagnostic: – T ests the Memory Channel adapter(s) on the system running the diagnostic. – Runs as part of the initialization sequence when the system is powered up.
Example 5 – 1: Running the mc_cable T est >>> mc_cable 1 To exit MC_CABLE, type <Ctrl/C> mca0 node id 1 is online 2 No response from node 0 on mca0 2 mcb0 node id 1 is online 3 No res.

6 Using Fibre Channel Storage This chapter provides an overview of Fibre Channel, Fibre Channel configuration examples, and information on Fibre Channel hardware installation and configuration in a T ru64 UNIX or T ruCluster Server V ersion 5.0A configuration.
• A discussion on how you can use the emx manager ( emxmgr ) to display the presence of Fibre Channel adapters, target ID mappings for a Fibre Channel adapter , and the current Fibre Channel topology (Section 6.12). 6.1 Procedure for Installation Using Fibre Channel Disks Use the following procedure to install T ru64 UNIX V ersion 5.
10. Use the disklabel utility to label the disks used to create the cluster (Section 6.10). 11. Refer to the T ruCluster Server Software Installation manual and install the T ruCluster Server software subsets and run the clu_create command to create the first cluster member .

is manufactured. An N_Port is connected directly to another N_Port in a point-to-point topology . An N_Port is connected to an F_Port in a fabric topology . NL_Port In an arbitrated loop topology , information is routed around a loop. The information is repeated by each intermediate port until it reaches its destination.
• Arbitrated loop (Section 6.2.2.3) ______________________ Note _______________________ Although it is possible to interconnect an arbitrated loop with fabric, hybrid configurations are not supported at the present time, and therefore not discussed in this manual.
connected by the fabric switching function, which routes the frame from one F_Port to another F_Port within the switch. Communication between two switches is routed between two expansion ports (E_Ports).

• The units are divided between an HSG80 port 1 and port 2. • If there are dual-redundant HSG80 controllers, controller A port 1 and controller B port 2 are normally active; controller A port 1 and controller B port 1 are normally passive. • If one controller fails, the other controller takes control and both its ports are active.
Y ou can, however , add the hardware for a second bus (another KGPSA, switch, and RA8000/ESA12000 with associated cabling) and use LSM to mirror across the buses.
If you consider the loss of a host bus adapter or switch, the configurations in Figure 6 – 6 and Figure 6 – 7 will provide better throughput than Figure 6 – 5 because you still have access to both controllers. W ith Figure 6 – 5, if you lose a host bus adapter or switch, you lose the use of a controller .

7 Preparing A TM Adapters The Compaq T ru64 UNIX operating system supports Asynchronous T ransfer Mode (A TM). T ruCluster Server supports the use of LAN emulation over A TM for client access.
Most data traffic in existing customer networks is sent over Local Area Networks (LANs) such as Ethernet or T oken Ring networks. The services provided by the LANs differ from those of A TM, for examp.
– Broadcast and Unknown Server (BUS): A BUS handles broadcast data sent by a LAN emulation client, all multicast data, and data sent by a LAN emulation client before the A TM address has been resolved. Figure 7 – 1 shows an A TM network with two emulated LANs.

10 Configuring Systems for External T ermination or Radial Connections to Non-UltraSCSI Devices This chapter describes how to prepare the systems for a T ruCluster Server cluster when there is a need for external termination or radial connection to non-UltraSCSI RAID array controllers (HSZ40 and HSZ50).
Follow the steps in T able 10 – 1 to start the T ruCluster Server hardware installation procedure. Y ou can save time by installing the Memory Channel adapters, redundant network adapters (if applicable), and KZPSA-BB or KZPBA-CB SCSI adapters all at the same time.
The DWZZH-series UltraSCSI hubs are designed to allow more separation between member systems and shared storage. Using the UltraSCSI hub also improves the reliability of the detection of cable faults. A side benefit is the ability to connect the member systems ’ SCSI adapter directly to a hub port without external termination.
