Changing lan name - eg: lan6 to lan0
Recently i have changed one network adapter from one slot to another in rx6600 server.
OS HP Unix 11.31.
After changing the slots the lan number got changed for some network interface as given below.
Before Changing Card slot
0/7/1/0/4/0 lan0
0/7/1/0/4/1 lan1
0/7/1/0/6/0 lan2
0/7/1/0/6/1 lan3
0/4/2/0 lan4
0/4/2/1 lan5
After changing card slot
0/4/2/0 lan4
0/4/2/1 lan5
0/7/1/0/4/0 lan6
0/7/1/0/4/1 lan7
0/7/1/0/6/0 lan8
0/7/1/0/6/1 lan9
How can i go back to the previous stage without changing the slot.
can somebody help?

Re: Changing lan name - eg: lan6 to lan0
You don't.
lan numbers are assigned by the system and we adjust our systems to this fact, we don't adjust the system to pick the lan number we want.
You can take out the /etc/ioconfig file and at boot it will reconfigure.
The results are random and the possible loss of system is high.

Or you could use ioconfig to rename the device. Either way you would probably have to reboot the server. You can do a search inthe forums for ioconfig to get a better idea of how to use it. I have to find my notes.

However, it does mean that if you move a card from one slot to another (thus changing the HW path) new names are assigned.
The only way to change them is the aforementioned ioconfig path, which should be undertaken with care.

Do you really need to change the lan name, its better if you just assign the IPs again, I suppose that simple.

Re: Changing lan name - eg: lan6 to lan0
The Server is configured in HP Serviceguard Cluster with Oracle RAC.
So just changing IP will not work for me.
With ioconfig how can i achieve this. We don't want to do any modification in Sg and RAC level.

Re: Changing lan name - eg: lan6 to lan0
Starting from square one, devices will be named in discovery order - that is to say, they will be named based on the order in which HP-UX walks the I/O bus/busses.
However, once named, a devices name is "permanent." So, if you *add* another set of devices they will be named starting from where the names left-off, in bus walk order.
So, at this point, the names of the devices may not be "purely" in bus walk order - it depends on when/where devices were added.
If you now remove the ioconfig file, you have blown away all knowledge of device names. Devices will now be named in bus walk order.
This may not match what you built-up before.

Rick I remember we used to change device names with dsfmgr online with Tru64, I suppose it was becuase they had a hardware DB.Do we have anything like that in HPUX well I have not come across any.
