Description of problem:
all Linuxguest on our zVM has 2 QDIO (virtuell) interfaces one to over
an vswitch to the real LAN and on to a VM internal "guestlan".
So at the install both are present and anaconda does them show in
Network config dialog. After the reboot the secound interface with his
entry at /etc/chandev was lost so the guestlan wasn't abel to connect.
After apply the entry and calling
echo "reset_conf\;read_conf" > /proc/chandev the device seems to be
initialized. but without reloading the qeth kernel module it doesn't
be able to aktivate.
service network restart shows:
"qeth device eth1 does not seem to be present, delaying initialization."
After stoping eth0 from a x3270 and unloading qeth.o the "service
network start" does bring up the interface.
I doesn't know if it is an ifconfig or a kernel(module) failure,
because the driver should aktivate after reread chandev.conf.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot after new install
3.echo "reset_conf\;read_conf" > /proc/chandev
4. service network restart
Actual Results: ifup: qeth device eth1 does not seem to be present,
network: Bringing up interface eth1: failed
Expected Results: kernel: qeth: Trying to use card with devnos
kernel: qeth: Device 0xA500/0xA501/0xA502 is an OSD Express card
kernel: with link type Gigabit Eth (no portname needed by interface)
kernel: ip_tables: (C) 2000-2002 Netfilter core team
ifup: Cannot get driver information: Operation not supported
network: Bringing up interface eth1: succeeded
It appears in both Arch's S390 and S390x.
