82 • Troubleshooting UPSMON User Manual
Problem: A false alarm by the Upsagent happens in constant intervals.
Answer: Is the port ”free” meaning that no ”getty” processes are active? No ”Login” must run on this port. In the file inittab
”respawn” has to be overwritten with ”off”.
Problem: When I start the ups_shut.scr script I get a syntax error.
Answer: Change default shell to sh.
Problem: The configuration menu can not be read at the terminal type 978x of a Siemens-computer.
Answer: For a correct screen display the baudrate has to be set to 9600/19200.
Problem: The message ”Write error on /dev/..” or TCSAGET error on...” appears.
Answer: Especially with IBM AIX a ”clocal” has to be entered in the SMIT (configuration menu) in the boot-default settings
of the interface that should be used by the UPS. (The interface should be without modem control signals and no
hardware handshake).
Problem: After changes are made in the Upsetup menu the Upsagent starts unchanged.
Answer: Changes have been made in the ups_conf menu but a running Upsagent has not taken over the changes. Stop the
daemon and restart.
Problem: Some files on the CD-ROM are not displayed in the correct way or the install script ends abnormally.
Answer: Mount the CD-ROM as "case sensitive". Check the correct mount commands for your system. E.g. HP UNIX may
use: "mount -o cdcase <device> <mountpoint>" or DEC ALPHA OSF1 V 3.2 "mount -t cdfs -o noversion /dev/rz6c
/cdrom2" (rz=Disktyp, 6= SCSI address, c=partition, c for total). SINIX: "mount -F hs /dev/ios0/sdisk005s0 /cdrom".
LINUX: "mount -t iso9660 /dev/scd0 /cdrom". See your specific UNIX mount options.
Problem: Error message during start of Upsagent: ”Communication lost".
Answer: a. Is the UPS-cable plugged in the correct way (Plug-side of the SUB D9 to the UPS)? Do you use any
adapters? If so, check the contact of the cable, the pin layout and their correct correspondence to your UPS
user manual interface description.
b. Has the port of the Unix-system been indicated correctly? The correct ”Name” of the serial port has to be
indicated in the menu Upsetup or with the editor in the configuration file.
Example: The entry in the configuration menu could be: ”Ups Connection: /dev/tty01". If the DEVICE
exists it can be entered. Even if you can enter a DEVICE it does not necessarily mean that this is the one
where the UPS-cable is plugged in.
c. Is the port directly located at the computer or at a multiplexer or Terminal-server? Some Terminal-server do
not give certain interface settings, but change the port address after every boot. On such a distributor a
connection is not possible. With Multiplexer 1 only contact information is transmitted.
d. Have you been logged in as ”root” or ”superuser”? Login as ”root” and restart.
e. Using Siemens RM-models this message appears if the port is unknown or has not been configured at the
system-installation. If RM-models have not configured a port you can do this with the termadd command.
termadd -T serial -n UPS -b motherboard 0,2 -d -l generic
Where ”UPS” is the name of the interface for the UPS service (/dev/UPS) and ”motherboard” names the
location of the interface. For ”motherboard” a different device can be used, such as the ITP-interface
distributor or CHASE I/OLAN on large RM models. The UPS service can also be used on all interface
distributors, if a clear port is dedicated. At the command entry ”motherboard 0,1” 0 stands for the board and
1 for the port address. A newly created device should be moved from the directory /dev/term to /dev.
