Hi,
Sorry for commenting so late, but regarding #1, make sure that you remove all
IP device restrictions. This is found in /etc/zipl.conf... the statements start
with "rd.znet":
i.e. -
rd.znet=qeth,0.0.0600,0.0.0601,0.0.0602,layer2=0,portno=0,portname=foo"
I hope this helps.

Hi,
I am not a Redhat expert so can't comment on #1. But for #2, no, you do not
want to delete those tempfs file systems. This is how the kernel keeps track
of things. These are in memory temporary file systems that are created at boot
and disappear at shutdown. Leave these alone.

Hi,
I would appreciate if you can help me with the following:
1. Changing the Interface name (I followed the instructions on the link :
https://access.redhat.com/solutions/2592561 and it didn't work.)
# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enccw0.0.0100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP mode DEFAULT qlen 1000 link/ether 02:00:03:00:00:8c brd
ff:ff:ff:ff:ff:ff
I need to change enccw0.0.0100 to eth0 because we have so many scripts which
uses eth0.
# nmcli connection modify enccw0.0.0100 connection.interface-name eth0 # nmcli
connection up eth0
Error: unknown connection 'eth0'.
# udevadm info /sys/class/net/enccw0.0.0100
P: /devices/qeth/0.0.0100/net/enccw0.0.0100
E: DEVPATH=/devices/qeth/0.0.0100/net/enccw0.0.0100
E: ID_NET_DRIVER=qeth_l2
E: ID_NET_NAME_MAC=enx02000300008c
E: ID_NET_NAME_PATH=enccw0.0.0100
E: ID_PATH=ccwgroup-0.0.0100
E: ID_PATH_TAG=ccwgroup-0_0_0100

E: SUBSYSTEM=net
E: SYSTEMD_ALIAS=/sys/subsystem/net/devices/enccw0.0.0100
E: TAGS=:systemd:
E: USEC_INITIALIZED=85059
2. File system - When I installed, I created single partition "/" for the
entire disk. But, after the install completed, I see the following. Should I
go ahead and delete all "tmpfs"?
df -T
Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/dasda1 ext4 21160896 4004264 16058644 20% /
devtmpfs devtmpfs 8141464 0 8141464 0% /dev
tmpfs tmpfs 8155160 0 8155160 0% /dev/shm
tmpfs tmpfs 8155160 8468 8146692 1% /run
tmpfs tmpfs 8155160 0 8155160 0% /sys/fs/cgroup
tmpfs tmpfs 1631032 0 1631032 0% /run/user/0
By default we partition the whole disk as on ECKD and use SAN for all other
purposes.
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/dasda1 19G 16G 2.1G 89% /
tmpfs 499M 0 499M 0% /dev/shm
Appreciate your help.
Regards,
Tom
