For some reason I am not getting any e-mail from my own posting.
I get all other Linux-390 postings.
I had to go to the Linux-390 index to read them.
In response to Ursula Braun,
lscss did not show F100-F101.
Modules cu3088 and lcs loaded since I already have F200 LCS Ethernet working.
Here is what I did to fix the issue.
I finally got F100 to work by defining an OAT and then configing off CHP(F1)
and then back online.
It added it as eth0 and dropped the existing F200 connection (ifconfig showed
it online).
I just did an "ifdown eth1" and "ifup eth1"
I was using LCS because?...
Well..... LCS was familiar to me and I did not know that QDIO could be shared
until last 2 weeks.
I am in the process of converting the LCS to QDIO. That is why I wanted to add
the F100 so I could be logged on to z/Linux and delete F200 and then load the
new IODF and then add F200 back as QDIO.

Subject: Help needed adding LCS Ethernet on a z9 for z/Linux LPAR (NO VM)
I am reposting to make sure this went out.
Any help would be greatly appreciated.

Hi,
We are trying to add another OSA LCS Ethernet on our z/9 z/Linux LPAR (SLES 10
sp1)
CHP F1 is defined in IODF as OSE
Looking at some PDFs I see that it say that we only have to do the following:
echo 0.0.f100,0.0.f101 > /sys/bus/ccwgroup/drivers/lcs/group
1. Without an "echo -n" we get an echo invalid argument
2. With "echo -n " we get no message and nothing build in the appropriate
/sys/bus/ccwgroup areas.
Next we tried YAST, we rebooted and it F100 times out.
F200 is already an LCS, but we want to convert it to QETH as soon I we can get
this second LCS Ethernet working.
There is NO OAT for F100 , but F200 (which works, installed via installation
process) has an OAT.
CHP(F1) is offline to all but this LPAR.
I have done an "zipl -c /etc/zipl.conf"
Here is my /etc/zipl.conf
[defaultboot]
defaultmenu = menu
[SLES_10_SP1]
image = /boot/image-2.6.16.54-0.2.3-default
target = /boot/zipl
ramdisk = /boot/initrd-2.6.16.54-0.2.3-default,0x1000000
# parameters = "root=/dev/disk/by-id/ccw-IBM.75000000029646.3800.2f-part2

parameters = "dasd=382f,392f
root=/dev/disk/by-id/ccw-IBM.75000000029646.3800.2f-part2 TERM=dumb"
:menu
