Hi Maryn, I logged into your LPAR br14p07 and took a quick look, and I saw the
updated 75-persistent-net-generator.rules file, and it does contain Brian's
patch. And sure enough when I issued the command "udevadm trigger
--subsystem-match=net --action=add", it added a record for eth0 that did not
exist before:
root@br14p07:~# cat /etc/udev/rules.d/70-persistent-net.rules
...
# LPAR virtual device at 30000003 (ibmveth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="16:59:ce:bf:9b:03", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth0"
I then rebooted the system but could not get back in since I did not
have the PW for this node. However I could see that it was pingable
after the reboot so I'm pretty sure the eth0 interface came back
normally after the reboot. You can check that for me please.
So it looks like Brian's patch fixes it, at least as far a the udev rule
in concerned. Now we need to know if you are still experiencing the
problem you reported.
The above "udevadm trigger" simulates what happens when new interfaces
are added or when the system first boots. For any interface we want to
be persistent we should have a rule written to /etc/udev/rules.d/70
-persistent-net.rules, and that should be working now for the partition
LAN interfaces. Once the rule is there, the interface (eth0 in this
case) should not move when other interfaces are added or removed, or the
system is rebooted.
You can test various scenarios by deleting the /etc/udev/rules.d/70
-persistent-net.rules file and allowing it to be recreated. So to test
the scenario you reported here, I would delete the file and reboot the
system, and ensure you have an entry for eth0 (like the one above)
written to the 70-persistent-net.rules file after the reboot. Then, you
should be able to hotplug the additional interfaces, and reboot, and
eth0 should not move. If this does not happen let us know. Thx.
