Changing LAN PPA no

[Bipin Baghele]

Hi,
I have 4 nic ports (2 dual lan cards) on RX6600 server with HP Ux 11.23 MCOE for clustering in 2 node cluster.
The lanscan output on 1 machine is like this.
-------------------------
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/4/2/0 0x0017A451B924 2 UP lan2 snap2 1 ETHER Yes 119
0/4/2/1 0x0017A451B925 3 UP lan3 snap3 2 ETHER Yes 119
0/6/1/0 0x0017A451A0DC 6 UP lan6 snap6 3 ETHER Yes 119
0/6/1/1 0x0017A451A0DD 7 UP lan7 snap7 4 ETHER Yes 119
--------
I would like to change the lan2/lan3/lan6/lan7 to lan0/lan1/lan2/lan3 (their respective PPA no) so it matches with another node. Basically this node had 8 lan ports with 4 dual port cards and we moved 4 ports (2 dual NIC cards to another server) after OS install was done.
Is this possible or not. If yes, how?. I can reboot the server or change files needed, since this server I just build up.

It's really not essential that they be the same but ...

1. cd /
ioscan -f | grep -e "DEVICE" -e "INTERFACE" | grep -v "target" | awk '{printf("%-20.20s %-12.12s %3d\n",$3,$1,($2 + 0))}' > devlist # all of this is one line

This creates a file listing HW Path, Class, and Instance Numbers for the devices. It's the Instance Numbers that you want to change BUT make certain that there are no duplicates of the same class. It's fine to have a LAN 1 and a disk controller 1 but there can be at most 1 LAN card with instance 1.

2. Vi devlist and assign instance numbers 0, 1, 2 to lan0, lan1, and lan2 respectively. Leave the disk assignments as they are. Save the file.

3. Now blow away the ioconfig file and reboot:
cd /stand
mv ioconfig ioconfig.old
cd /etc
mv ioconfig ioconfig.old
shutdown -r 0

4) The system bootup will stop at ioinitrc message:
/sbin/ioinit -c # this will recreate the missing ioconfig files
/sbin/ioinit -f /devlist -r # this will read in your edited file and reboot. You may see error messages like "Input is identical". Pay no attention.

After the box has rebooted, do a lanscan and make sure your assignments are as you expected.

As suggested completed the steps but server did not reboot. See the output, while it does read the devlist file and instance no were 0, 1,2,3. I changed only lan entries, only 4 lan entries were their in devlist file.

Yes, it worked but did not reboot on its own after running the command
# sbin/ioinit -f /devlist -r

So, I did ctrl-d at that prompt and it wnet ahead with instance no changes as wanted.

Thanks for your help.
