11.00.01 Operating and Maintenance Procedures 2. Operating and Maintenance Procedures This chapter explains the basic operating procedures used for PA-8500 Continuum 400 Series system operation and maintenance under the HP-UX 11.00.01 operating system.
11.00.01 Operating and Maintenance Procedures not required. The primary bootloader reads the CONF file on the flash card for instructions on system configuration during the bootstrap process before issuing the lynx$ prompt, but specific commands entered at the primary bootloader lynx$ prompt take precedence over the instructions in the CONF file. When the boot command is executed, the lynx primary bootloader loads and transfers control to isl (the secondary bootloader).
11.00.01 Operating and Maintenance Procedures boot 2 NOTE: To boot from the flash card in card cage 3, enter boot 3 instead. Once the system finds the boot device, it displays the boot hardware path, transfers control to the primary bootloader, and displays the bootloader prompt lynx$. NOTE: To get a complete list of the bootloader commands, enter help at the lynx$ prompt.
11.00.01 Operating and Maintenance Procedures remote system. You will be logged out and control will be returned to the system console. 3. Before changing to single-user state, you will be asked if you want to send a message to inform users how much time they have to end their activities and when to log off. If you want to send a message, enter y. 4. Type the message (on one or more separate lines) announcing the shutdown.
11.00.01 Operating and Maintenance Procedures reboot Otherwise, enter the following: shutdown -r 2.4 Console Command Menu The Console Controller supports a command menu that can be used to issue key machine management commands to the system from the system console. It can reboot or execute other commands on a nonfunctioning system. To access the console command menu from a V105 console using an ANSI keyboard, press the F5 key.
11.00.01 Operating and Maintenance Procedures nothing is entered for 20 seconds, the system automatically exits the console command menu.) . - Displays the current firmware version number. 2.5 Configuring the Console Terminal Perform the following procedure to configure the console terminal. 1. Consult the terminal manual for specific configuration information or instructions. 2. Execute the following commands at the console or put them into the root /.profile file.
11.00.01 Operating and Maintenance Procedures Examples: CPU-Memory Board or Console Controller Bus Hardware Path of Component Component System (0) CPU-Memory board CPU (processor) 0/0/0 System (0) CPU-Memory board CPU (processor) 0/1/0 System (0) CPU-Memory board Memory Module 0/0/1 System (0) CPU-Memory board Memory Module 0/1/1 RECC (1) Console Controller Console Controller 1/0 RECC (1) Console Controller Console Controller 1/1 2.6.1.
11.00.01 Operating and Maintenance Procedures fifth-level addresses, one for each port. Example: LAN Cardcage Adapter Slot # 2 3 LAN Adapter Hardware Paths 0/2/3/0/4, 0/2/3/0/5, 0/2/3/0/6, 0/2/3/0/7 2.6.2 Logical Hardware Configuration There are four major logical components on the system bus: ● Logical cabinet ● Logical LAN manager ● Logical SCSI manager (LSM) ● Logical CPU-Memory board. 2.6.2.
11.00.01 Operating and Maintenance Procedures mapped independently from the actual hardware addresses. A physical SCSI bus can have one or two initiators located anywhere in the system, but the logical SCSI manager allows you to target each SCSI bus by its logical SCSI address without regard to its physical location. By using a logical SCSI manager, you can configure (and reconfigure) dual-initiated SCSI buses across any SCSI controllers in the system.
11.00.01 Operating and Maintenance Procedures The logical CPU-Memory board addressing convention is as follows: ● First-level address identifies the logical CPU-Memory board number (always 15). ● Second-level address identifies the resource type (0 for CPUs, 1 for memory, and 2 for the Console Controller).

Theory of Operation 5. Theory of Operation This section contains an overview of the theory of operation for the PA-8500 Continuum 400 Series systems. It provides information on how the system operates and includes a description of each of the following major assemblies/subsystems. ● Suitcase ● PCI Subsystem ● Disk Subsystem ● Power and Control Subsystem ● Cooling Subsystem A high-level architectural view of the PA-8500 Continuum 400 Series system is shown in Figure 5-1. Figure 5-1.
Theory of Operation 5.1 Suitcase One of the major assemblies in the PA-8500 Continuum 400 Series system is the suitcase. There are two identical suitcases. The operating status and fault conditions of the suitcase are displayed on LEDs located on the front bezel of each suitcase. The suitcase houses the following components/subassemblies: ❍ CPU-Memory board ❍ Cooling fans ❍ Power supply 5.1.
Theory of Operation The two PA-8500 processors on either side communicate with each other and the Mustang ASIC (interfaces the processors with I/O and memory) over a 120-Mhz bus (Runway bus). There are two Runway busses (C-side and D-side). Because of timing and pin constraints these busses are not crosschecked, but any subsequent transactions to the memory, I/O, or Console Controller are checked.
Theory of Operation and eight of those bits are multiplexed with the data read from the PROM. An 18504 latch part is used to hold the address at the inputs to the PROM to allow the pins to be multiplexed. The backplane (X-Bus) interface on the CPU-Memory board is provided by a pair of Lens ASICs that interface the CPU subsystem with the I/O subsystem . The Lens ASIC connects the X-Bus with the CPU-Memory board's internal I-Bus.
Theory of Operation module on the CPU-Memory board. Each Console Controller module operates independently of the rest of the CPU-Memory board on which it is located. It functions as a centralized controller for the entire system performing the following critical functions: ● Serves as a central collection point for Maintenance and Diagnostics (M&D) services. ● Controls and monitors the main power supply for the system. ● Provides a console command (front panel) interface.
Theory of Operation velocity profile. Air then passes through the exhaust fans and is discharged out the top of the enclosure. Heat dissipation for the suitcase is 800 Watts. System flow rate is 150-250 CFM, resulting in an overall bulk temperature rise across the suitcase of approximately 9 ° C (worst case). Temperature information is acquired by thermal sensors in the suitcase and is used to drive the fan speed.
Theory of Operation PCI adapter cards. The PCIBs act as the interface between the system bus (XBus) and the PCI buses. They isolate the PCI cards from the suitcase, so that a suitcase failure does not adversely affect PCI card availability. 5.2.1 PCI Bus The PCI bus is an industry standard bus developed by Intel. It is a fully synchronous 32-bit bus running at 24 MHz. It uses a multiplexed address/data bus to transmit information. The bus is a high bandwidth, low latency local bus that only supports 5.
Theory of Operation bus (XBus) provides the interconnection between the CPU-Memory boards and the PCIB. The PCIBs contain two ASICs that each talk to a PCI bus and a FLASH PROM for OS boot. A 20-MB removable PCMCIA flash card resides on each PCIB card. The PCIB boards do not run in lockstep mode and cannot be duplexed. Their normal operational state is online simplex.
Theory of Operation File Name Description CONF The bootloader configuration file. This file is equivalent to the /stand/conf file on the root disk. BOOT The secondary bootloader image, which is used to boot the kernel. At system startup, the operating system boots from the flash card and assumes that it contains the correct version of the bootloader configuration file in CONF. If there is no CONF file, the system cannot boot.
Theory of Operation 960. The 4-Port AIB has one 100-pin D-shell connector that connects to a fan-out cable that separates into multiple ports. Ordering a U403-01 provides an ARTIC 960, a 4-port AIB, and an AIB cable that fans out into four DB37M connectors adhering to V.36, that is, ISO 4902. The U403-02 provides an ARTIC 960, a 4-port AIB and an AIB cable that fans out into four DB25M connectors adhering to EIA530, that is, RS-422.
Theory of Operation ISO 4902 (V.36) 2.048 Mbps ISO 4903 (X.21) 2.048 Mbps V.35 2.048 Mbps The actual speeds supported by Continuum 400 systems are software dependent. Refer to the OS literature for more detailed specifics within each operating environment and protocol. 5.2.3.3 U420/420E T1/E1 ISDN Adapter The U420/U420E is manufactured by ITK Telekommunications AG and is known commercially as the ITK ix1-primary. The U420 is used to provide both T1 (1.544 Mbps) and ISDN PRI interfaces.
Theory of Operation ● Standard RS-232 cable 5.2.3.5 U501 Single-ended SCSI Adapter (DPT PM3224W) The U501 single-ended SCSI adapter is a fast wide 16-bit SCSI host adapter and RAID (Redundant Array of Inexpensive Drives) controller. It contains three physical SCSI ports, two with internal connectors, and one external. The internal connectors are used for driving the integrated disk drives. The external connector is for connecting an optional tape drive.
Theory of Operation With Category 3 wire, the U513 operates at 10 MB/sec.; with Category 5 wire, it can operate at either 10 MB/sec or 100 MB/sec. The U513 supports half duplex 10BaseT and 100BaseTx operation. The card automatically senses the speed of the ethernet, and configures itself properly. 5.2.3.9 U520 Token Ring Adapter The Continuum Series 400 employs the U520 PCI adapters to provide Token Ring LAN interfaces.
Theory of Operation unit are designed to support single-ended (SE) SCSI operation. Optional I/O modules are available to allow extended length SE operation. All connections to the enclosure (SCSI, I/O & power) are located on the rear of the enclosure. Other features of the disk subsystem are: ● Disk drive spin-up under host control (no delay). ● Operates at 20 MB/sec (Fast/Wide) SCSI. ● Automatic assignment of SCSI IDs. ● Dual 48 VDC power supplies with isolated inputs.
Theory of Operation 5.3.2 Disk Enclosure Components The disk shelf backplane is the heart of the enclosure. It distributes the SCSI bus and power to all of the drives and provides the interconnection between all other modules that are plugged into it. The disk slots bring the SCSI bus and power connections to each disk drive. Each slot has two LED’s associated with it. The first is a green LED that is driven by the LED_OUT signal directly from the drive, and the second is a red LED driven by the SES unit.
Theory of Operation configuration information for the enclosure and to set and sense standard bits for each type of element that may be installed in the enclosure. Since the SES unit communicates over the SCSI Bus, it consumes a SCSI ID. In the event of an SES failure, no data is lost and no disks become unavailabe . What is lost is the information pertaining to the status of power supplies, fans, and temperature within the enclosure.
Theory of Operation Drive # PS 1 PS 0 6 5 4 3 2 1 0 N/A SCSI ID n/a n/a 14 5 4 3 2 1 0 15 NOTE: HBA 0 and HBA 1 (U501s) are always set to SCSI ID 6 and 7, respectively. SCSI IDs 8-13 are reserved for expansion. The PA-8500 system does not daisy-chain disk shelves. Each shelf is a fully independent storage node; fault-tolerance is achieved by duplication of hardware, independent power and data paths, and mirroring data across the shelves. 5.3.
Theory of Operation Cabinet power cable AW-001038 Disk power "Y" cable AW-001036 5.4 Power and Control Subsystem The power subsystem consists of an AC front end unit (Tray 1) and a power shelf (Tray 2). Both are located in the upper section of the cabinet. 5.4.1 Power Tray 1 Tray 1 converts AC power into 48-volt power and supplies 2000 watts of redundant power . It supplies the suitcases, disks, and Tray 2 with 48 VDC power.
Theory of Operation fault indicators located on the top and rear of the cabinet.. Tray 2 also supplies the power for the alarm control units (ACU). It contains the following components: ● 2 PCI power supplies with internal fans (forced convection) ● 2 Alarm control units - natural convection cooled ● Power backplane ● 2 Circuit breakers ● LED status indication Each PCI power supply accepts a single 48 VDC source.
Theory of Operation 5.4.3 Power Specifications The power requirements for PA-8500 Continuum 400 Series systems are shown in the following tables. AC operating parameter Minimum Maximum AC input voltage 180 VAC 264 VAC AC input frequency 47 Hz 63 HZ AC current available per line cord 20 Amps Source power factor @ Po>25%, Vin=nominal 0.80 Tray 1 power factor @ full load 0.90 1.0 file:///H|/CSDoc/leotsg/section5.

Theory of Operation The cooling system cools internal cabinet components by drawing air in through the front of the cabinet and exhausting it out the rear and top as follows: ● Two fans at the top of each suitcase draw air through the bottom of the cabinet to cool the boards within the suitcase. ● The air exhausted through the top of the suitcases is drawn upward to cool the PCI cards and is exhausted through vents in the rear of the card cage.
Theory of Operation Each disk power supply contains a fan. If one of these fails, the fan in the other power supply shifts to high speed to compensate for the loss. It returns to normal operation when the failed disk power supply is replaced. Each PCI power supply has one, fixed-speed fan, so there is no shift to high-speed operation when one PCI power supply fails. Each suitcase has two fans.
