PPA of a LAN card

[ISS Unix Admin]

I have a D280 with a 100BT LAN card (J3516A)- dual port.

Originally - under HPUX10.20, the on board LAN card had a PPA of 2 (i.e. INTERFACE_NAME[0]=lan2).

Having cold installed HPUX 11.00, the PPA has now changed to 3 (lan3).

Questions:-
1) How and when is the PPA determined/calculated?
2) Is it possible to force the PPA to another value e.g.back to what is was (2).

Thanks

You can force the instance number of lan cards (and other IO interfaces) by using the ioinit command.

ioinit -f infile -r

Where infile has the format:
h/w_path class_name instance_#

Note: ioinit will not "overwrite" an already claimed instance number. It may be necessary to run the process twice, once to "fre up" the instance numbers you want to claim and again to claim them.

Note2: the -r flag will reboot your system once the reassignment is accomplished (assuming the ioinit returns without errors). If you do not use the -r, the change will not take effect until after reboot, and the use of rmsf or insf in the interim might destroy the assignments you have specified.
