Troubleshooting LAN/9000

Diagnostic Flowcharts

Flowchart 3 Procedures

A. ifconﬁg not found. The command has been relocated on

the system, deleted, or /usr/sbin is not in your PATH.

B. Restore /etc/ifconﬁg from media. You can restore

ifconfig from the last good backup tape or your

install/update tape. Go to Flowchart 2.

C. Bad system call. Networking is not conﬁgured into the

HP-UX kernel.

D. Reconﬁgure HP-UX kernel to include LAN/9000

software. Edit the /stand/system ﬁle to include

LAN/9000 software. Refer to chapter 3 for a list of LAN

drivers.

E. No such interface name. The interface name passed to

ifconfig does not exist on the system. Check spelling

and names of interfaces on the system using lanscan.

If you have more than one LAN card, make sure the

number of LAN cards has been conﬁgured into the

kernel and that an ifconfig command has been

executed for each.

F. Execute lanscan. Execute lanscan to display

information about the LAN cards in your system.

G. Find correct interface name. Using the correct interface

name, start again with Flowchart 1.

H. Is Hardware State UP? Verify the state of the hardware

with the output from the lanscan command. If the

Hardware State is up go to I, otherwise go to H.

I. Execute lanadmin. Use the lanadmin command to reset

the LAN card. Go to Flowchart 2.

J. Check for the plumbing error: Bad ﬁle number. If you

see this error, the TCP/IP stack has not yet been

initialized.

K. Initialize the TCP/IP stack. Execute the command

/sbin/init.d/net.init start.

L. Check the status of the network. Use the command

netstat -in. Make sure that the loopback interface

lo0 appears in the display.
