Page 13: Introduction
Chapter 1 Introduction The Compaq AlphaServer GS160/320 and GS80 systems are high-performance server platforms designed for enterprise-level applications. They offer a high degree of scalability and expandability. The GS160/320 system uses up to four Alpha microprocessors in each quad building block (QBB). Two QBBs are paired back-to-back and rotated 180 degrees with reference to each other and then enclosed in a system box.
Page 14: Alphaserver Gs160/320 And Gs80 Systems
AlphaServer GS160/320 and GS80 Systems The AlphaServer GS160/320 system and GS80 rack system are separate, but related, in that they use the same switch technology. The CPU modules, memory modules, and power modules are also the same. In the GS160/320 system, the modules are in a system box in a cabinet. In the GS80 rack system, the modules are in a drawer.
Page 15 An expander cabinet can be used to house additional I/O and storage. System Management Console The console device, called the system management console (SMC), is a Compaq Deskpro PC, a DECserver 90M terminal server, and associated hardware and software. For installation instructions and user information, see the AlphaServer GS80/160/320 System Management Console Installation and User’s Guide.

Page 94: Setting Boot Options
Setting Boot Options You can set a default boot device, boot flags, and network boot protocols for Tru64 UNIX or OpenVMS using the SRM set command with environment variables. Once these environment variables are set, the boot command defaults to the stored values. You can override the stored values for the current boot session by entering parameters on the boot command line.
Page 95 The syntax is: set bootdef_dev boot_device boot_device The name of the device on which the system software has been loaded. To specify more than one device, separate the names with commas. Example In this example, two boot devices are specified. The system will try booting from dkb0 and, if unsuccessful, will boot from dka0.
Page 96 6.2.3 Boot_osflags The boot_osflags environment variable sets the default boot flags and, for OpenVMS, a root number. Boot flags contain information used by the operating system to determine some aspects of a system bootstrap. Under normal circumstances, you can use the default boot flag settings.
Page 97: Openvms Boot Flag Settings
OpenVMS Systems OpenVMS systems require an ordered pair as the flags_value argument: root_number and boot_flags. root_number Directory number of the system disk on which OpenVMS files are located. For example: root_number Root Directory 0 (default) [SYS0.SYSEXE] [SYS1.SYSEXE] [SYS2.SYSEXE] [SYS3.SYSEXE] boot_flags The hexadecimal value of the bit number or numbers set.
Page 98 Example In the following Tru64 UNIX example, the boot flags are set to autoboot the system to multiuser mode when you enter the boot command. P00>>> set boot_osflags a In the following OpenVMS example, root_number is set to 2 and boot_flags is set to 1.
Page 99 6.2.5 ei*0_protocols or ew*0_protocols The ei*0_protocols or ew*0_protocols environment variable sets network protocols for booting and other functions. To list the network devices on your system, enter the show device command. The Ethernet controllers start with the letters “ei” or “ew,” for example, eia0. The third letter is the adapter ID for the specific Ethernet controller.

7.4.1 Setting Tru64 UNIX or OpenVMS Systems to Auto Start The SRM auto_action environment variable determines the default action the system takes when the system is power cycled, reset, or experiences a failure. On systems that are factory configured for Tru64 UNIX or OpenVMS, the factory setting for auto_action is halt.
Page 134: Soft Partitioning
Soft Partitioning Soft partitioning allows you to run multiple instances of an OpenVMS operating system on one hardware system. Soft partitions are created by setting environment variables that define the number of partitions, as well as the CPU modules, I/O risers, memory size, and size of shared memory.
Page 135: Srm Environment Variables For Soft Partitions
Table 7–5 SRM Environment Variables for Soft Partitions Environment Variable Definition lp_count n The number of soft partitions to create. Possible values are: Default. All IOPs, CPUs, and memory are assigned to one soft partition. No shared memory is defined. One soft partition is created (partition 0).
Page 136 At the SRM console prompt, you set values for one environment variable to define the number of soft partitions in the system, one to set the memory mode, and two for each partition that define the CPU and I/O modules in each partition.
Page 137 The number of soft partitions is set to 3. The set lp_io_mask0 1 command defines QBB0 (and its I/O risers) as residing in partition 0. Set lp_cpu_mask0 f assigns CPUs 0–3 to partition 0. The set lp_mem_size0 6GB command assigns 6 GB of memory to partition 0. Set lp_ io_mask1 6 defines QBB1 and QBB2 (and its I/O risers) as residing in partition 1.
Page 138: Hard Partitioning
Hard Partitioning Hard partitioning allows you to run multiple operating systems on one hardware system. Table 7–6 lists the SCM environment variables used to create hard partitions. After entering the SCM commands, set the control panel switch to Off and then to On to create the hard partitions.
Page 139 Partitioning a system is done at the QBB level: You can have a maximum of eight partitions. In hard partitioning mode: • System partitions are independent. • Each partition requires its own configuration tree. • Hardware isolation is required. • Address spaces are disjointed.

The SCM also provides remote server management functions. This chapter explains the operation and use of the SCM. Sections are: •...
Page 142: Console Serial Bus Subsystem
Console Serial Bus Subsystem The console serial bus (CSB) links microprocessors throughout the system, forming a monitoring and control subsystem managed by the system control manager (SCM). The SCM microprocessor is located on the standard I/O module in the master PCI box. Figure 8–1 shows a block diagram of the CSB, the microprocessors (or “managers”), and the SCM.
Page 143 The SCM communicates with the PCI backplane managers (PBMs), the hierarchical switch power manager (HPM), and the QBB power system managers (PSMs) distributed throughout the CSB subsystem. The subsystem has a power source separate from the rest of the system called auxiliary voltage (Vaux).
Page 144: System Control Manager Overview

Page 145 SCM Firmware SCM firmware resides on the standard I/O module in flash memory. If the SCM firmware should ever become corrupted or obsolete, you can update it manually using the Loadable Firmware Update Utility. The microprocessor can also communicate with the system power control logic to turn on or turn off power to the rest of the system.
Page 146: Scm Com1 Operating Modes
SCM COM1 Operating Modes The SCM can be configured to manage different data flow paths defined by the com1_mode environment variable. In through mode (the default), all data and control signals flow from the system COM1 port through the SCM to the active external port. You can also set bypass modes so that the signals partially or completely bypass the SCM.
Page 147 Through Mode Through mode is the default operating mode. The SCM routes every character of data between the internal system COM1 port and the active external port, either the local port or the modem port. If a modem is connected, the data goes to the modem.
Page 148: Bypass Modes
8.3.1 Bypass Modes For modem connection, you can set the operating mode so that data and control signals partially or completely bypass the SCM. bypass modes are snoop, soft bypass, and firm bypass. Figure 8–3 Data Flow in Bypass Mode QBBs (PSMs) PCI Boxes (PBMs) H-Switch (HPM)
Page 149 Figure 8–3 shows the data flow in bypass mode. Note that the internal system COM1 port is connected directly to the modem port. NOTE: You can connect a console device to the modem port in any of the bypass modes. The local console device is still connected to the SCM and can still enter the SCM to switch the COM1 mode if necessary.
Page 150 After downloading binary files, you can set the com1_mode environment variable from the SRM console to switch back to snoop mode or other modes for accessing the SCM, or you can hang up the current modem session and reconnect it. Firm Bypass Mode Firm bypass mode effectively disables the SCM.
Page 151: Console Device Setup
Console Device Setup You can use the SCM from a console device connected to the system or a modem hookup. As shown in Figure 8–4, local connection is made from the local port . You connect remotely from a modem connected to the modem port Figure 8–4 Setups for SCM (PCI Box) PK-0650-99...
Page 152: Entering The Scm
Entering the SCM Type an escape sequence to invoke the SCM from the SRM console. You can enter SCM from a modem, or from a local console device. From a VGA monitor, you can enter SCM commands from the SRM console.
