Hi, we have a strange problem with adding an extra network adapater in a SLES11
SP1
Starting with one works fine.
Adding one more always ends up with the first ip-address not posible to login
via ssh
but the added nr 2 ip-address works, so we can login ( thank's for that )
We have the following def in z/VM ( 5.4 )
NICDEF 0700 TYPE QDIO DEV 3 LAN SYSTEM VSW1
NICDEF 0710 TYPE QDIO DEV 3 LAN SYSTEM VSW1
below is from boot.msg, there is a strange rename, why ??
even more strange, after that rename in boot.msg, further down in same boot.msg
it displays eth0 as ip ending with 122 and eth1 as ip ending with 115 which is
the order we have configured them into, so what rename ???

We have looked into /etc/udev/rules.d/ for there 700 and 710 devices, only
thing differed
was portname that was ZLINUX in 700 and 0 in 710
So we changed it to ZLINUX1 in 710 (we have a SLES10 using 3 devices with that
naming)
same shit ;)
Then we also paid attention to portno atribut, which was 0 for both 700 and
710, so
we changed that to 1 for 710. reboot: same result
And by reboot I mean z/VM logoff logon.
The udev 51 files looks like this now:
cat /etc/udev/rules.d/51-qeth-0.0.0700.rules

There are also diffs in the files :
:/etc/sysconfig/network # cat ifcfg-eth0
BOOTPROTO='static'
IPADDR='10.248.33.122/25'
BROADCAST='131.97.122.127'
STARTMODE='onboot'
NAME='OSA Express Network card (0.0.0700)'
:/etc/sysconfig/network # cat ifcfg-eth1
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
INTERFACETYPE='qeth'
IPADDR='10.248.33.115/25'
MTU=''
NAME='OSA Express Network card (0.0.0710)'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'
don't know if these matters here.
If we remove ( or delete in Yast 710 'not configured' )
the first 700 with ip ending with 122 starts working again.
We really would appreciate some hints here !
