/dev/lan0 mounting
# insf -e
# insf -C lan
# insf -C lan -I 0
(The above command is not creating the device, something wrong in the argument?)
In HPUX11.11 I could find /dev/lan0 by default. But in HPUX11.31 there is no /dev/lan0 by default. I want to create this mount point by myself. Please let me know the steps to create.
For some more info on the Hardware.

Re: /dev/lan0 mounting
/dev/lan -> /dev/dlpi
All your networking interfaces must be showing as /dev/dlpi* .
Without /dev/lan do you have any issues ? How about nwmgr output shows ?

Re: /dev/lan0 mounting
if the dev files are not there you would create them with the mknod command
#man mknod
but as said, /dev/lan and /dev/snap should be linked to /dev/dlpi for 11.31.
what does
#ls -l /dev/lan
show
see this guide for more info on configuring lan devices in 11.31
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c02037128/c02037128.pdf
but what does lanscan show? or nwmgr --get commands
#lanscan
#nwmgr --get
the ioscan output looks fine

Re: /dev/lan0 mounting
Apparently in HP-UX 11.11, there was backward compatibility for the old LLA interface, but in 11.31, the old interface is completely gone and cannot be used anymore: the /dev/lan* devices don't exist and cannot be created. The newer DLPI must be used instead.
Unfortunately, DLPI is not fully compatible with LLA: to make a program use DLPI instead of LLA, the program must be modified.
You should look at the LLA to DLPI migration guide (it seems to still be available in old docs.hp.com!):

Re: /dev/lan0 mounting
Anything written since, oh, about 1995 or 1996 should have used DLPI. I believe that DLPI was present by default in 10.20. I just cannot recall if 10.20 shipped in '95 or '96.
