2 Troubleshooting This chapter describes how to use the pmux_diag diagnostic utility. It also describes how to troubleshoot the terminal, printers, and modem installation problems after the ports are configured and enabled.
Troubleshooting “The pmux_diag Utility Conventions” on page 23 “Driver Status Menu Selections” on page 24 “Diagnostics Menu Selections” on page 26 “Quit” on page 27 “Excessive Frequent getty Spawning” on page 28 “Terminal Login Problems” on page 29 “Printer Problems” on page 30 “Connecting a Modem” on page 32 “System Crashes or Panics” on page 34 22 Chapter 2
Troubleshooting The pmux_diag Utility The pmux_diag Utility The pmux_diag utility is a stand-alone program that supports diagnostic operations. Starting pmux_diag Utility To start the pmux_diag utility, complete the following steps: Step 1. Log in to the system as super user. Step 2. Run the following command at the command prompt: $ /usr/bin/pmux_diag Step 3. Press Enter.
Troubleshooting Driver Status Menu Selections Driver Status Menu Selections The Driver Status drop down menu displays the following selections: • Driver Status • Board Status • Counters • Topology Figure 2-1 shows the Driver Status selection. Figure 2-1 NOTE pmux_diag utility Driver Status main menu The pmux_diag utility version number is of the form B.x.xxxx Where: x - represents the release number, for example, 11.11 or 11.23.
Troubleshooting Driver Status Menu Selections Figure 2-2 Driver status display Board Status The Board (card) Status sub-menu enables you to view card specific information such as the card type, buffer block starting location, buffer size, and bus slot location. To view the card specific information, select Board Status sub-menu and press Enter. Information about additional boards, if any, is also displayed. Figure 2-3 shows the Board Status Display.
Troubleshooting Diagnostics Menu Selections Diagnostics Menu Selections The Diagnostics menu seletion enables the user to perform the following tests: • Loopback • Send Loopback The loopback test is designed to test the primary components of the adapter cards and their functionality. At any given time only one port can be tested. This simulates a loopback cable. Data is looped both towards the computer and towards the terminal.
Troubleshooting Quit Quit The last menu selection on the main menu is Quit. To quit the pmux_diag utility, select Quit and press Enter.
Troubleshooting Excessive Frequent getty Spawning Excessive Frequent getty Spawning You may encounter the following problem: Table 2-2 Excessive Frequent getty Spawning Problem The following message appears on the console: ‘tty1a1’ getty keeps dying. There may be a problem 28 Cause This message usually indicates that the incoming CD signal connected to a modem control port with CLOCAL set keeps toggling. The result is that the getty process dies because the loss of carrier spawns a new getty.
Troubleshooting Terminal Login Problems Terminal Login Problems Table 2-3 lists the problems you may encounter while logging in to a system: Table 2-3 Terminal Login Problems Problems Causes • No login prompt These problems can occur because of any of the following reasons: • Garbled message • Port is not enabled • • Problems logging in Port is set for wrong speed, parity, character size and so on.
Troubleshooting Printer Problems Printer Problems Table 2-4 lists the problems you may encounter while using a printer: Table 2-4 Printer Problems Problems • No output • Printer overflows after printing correctly • Printing is garbled Causes These problems can occur because of any of the following reasons: • General port problem • The printer connection is not wired correctly. • The port and printer settings are mismatched on baud rate, character size, or parity.
Troubleshooting Printer Problems Table 2-4 Problems Printer Problems (Continued) Causes Actions If you still have an overflow problem, lower the baud rate to 300 baud. If the overflow does not happen at 300 baud, it is a handshaking problem. Check your printer setup or switches, and ensure that XON/XOFF handshaking is setup. Also see the printer setup section in your HP-UX system administration manuals.
Troubleshooting Connecting a Modem Connecting a Modem To connect a modem to your system, complete the following steps: 1. Edit the /usr/lib/uucp/Devices file. For example, for a Hayes compatible 2400 baud modem (where 1a16 is the port where the modem is located), add the following entry in the /usr/lib/uucp/Devices file: ACU cul1a16 2400 hayes 2. Verify whether the serial port is working properly by testing it with a terminal. 3.
Troubleshooting Connecting a Modem 6. To view the major and minor number assigned for a device file, run the following command at the HP-UX prompt: $ ll /dev/tty4a8 The following output is displayed: crw--w--w- 1 bin bin 104 0x040700 Apr 5 03:22 /dev/tty4a8 Troubleshooting Modem Table 2-5 lists the common modem error messages, their causes, and describes how to troubleshoot modem connections.
Troubleshooting System Crashes or Panics System Crashes or Panics The system may crash after installing the MUX cards. Table 2-6 describes the cause of this problem, and also describes how to troubleshoot this problem. Table 2-6 System Crashes or Panics Problem Cause Your system crashes or panics when MUX cards are installed. The number of ports and the processes increase after installing the MUX cards. Because of the increase in work load, system crashes or panics.

Technical Specifications Cable Requirements and Specifications Cable Requirements and Specifications This section specifies cable characteristics and requirements. Physical Characteristics RS-232 serial interface cables must have the following characteristics: • Must be shielded • Must have low capacitance • Designed specifically for serial data transmission Grounding Requirements RS-232 interface cables must have shield grounded at both ends of the cable.
Technical Specifications Cable Requirements and Specifications The maximum length is the length of the cable from the adapter that is connected to a HP supplied interconnect device, such as a fan-out cable. The maximum length is based on a cable rated at: • 12.3 pF/foot, conductor to conductor • 22.4 pF/foot, conductor to shield If low-capacitance cable is unavailable or very long cable runs are required, short-haul modems can be used to increase the effective range of the RS-232 interface.
