Checking that the DTC management daemons are running
Download problems
The
rbootd
daemon is a process which runs on the HP 9000 host and is responsible
for downloading DTCs. The
rbootd
process can be started automatically when the
HP 9000 is booted. If
rbootd
is not running, the HP 9000 host cannot respond to a
DTC download request. Proceed as follows:
1 Follow the procedures in chapter 3 to verify that the daemons are running.
2 If the display code still does not indicate a successful download, follow the
troubleshooting procedure outlined in the hardware installation manual to try to
solve the problem.
3 Contact your Hewlett-Packard representative if you cannot solve the problem.
Solving dtcconfig, dtcping and dtcdiag problems
If you see error messages about dtcnmd and LAN device file names when you try to
run dtcconfig, dtcdiag or dtcping, follow the steps described for “Download
problems” above.
Checking that the Internet Services software is operational
The DTC uses the Telnet and TCP/IP protocols to establish terminal and device
connections from the DTC to the HP 9000 destination host. Therefore, Internet
services must be correctly installed and operating on the HP 9000 host.
Details of Internet Services operation and troubleshooting are beyond the scope of
this manual. However, correct operation of Internet Services on the HP 9000 can be
verified as follows.
1 Use the ps -ef command to make sure the
inetd
daemon is running. The
inetd
daemon spawns the
telnetd
daemon.
2 From the host, attempt to establish a Telnet connection to your own node by
typing the Telnet command at the shell prompt:
telnet myhostname
where
myhostname
is the node name or IP address of your own node.
3 If you suspect problems with the Internet Services on your node, consult the
Installing and Administering Internet Services manual.
