Re: [xcat-user] Node nic config error during install

[Russ Auld]

If you would like the Ethernet interface configured, add it to the nics table. The IP address shown by lsdef is probably coming from the hosts table.

The hosts table is useful if you want to build out /etc/hosts by running makehosts.

It?s also the right place to list interfaces that are not configured in-band, such as bmc?s. The nics table is where you want to list all in-band interfaces (to be configured by the os).

Russell,

Was not aware of confignics  going away.  Will look into replacing that piece correctly.

Nathan,

The nics table says this about the node:

"c001","bmc!172.16.4.26,ib0!172.16.8.26",,,"ib0!Infiniband,bmc!bmc",,"bmc!dracnet,ib0!ibnet","ib0!c001.ib.cluster,bmc!c001.drac.cluster","ib0!Type=InfiniBand CONNECTED_MODE=yes MTU=65520",,,,

Also, one of my team mates pointed out that the network-scripts RPM is not being installed by default.

Adding that RPM to the osimage template and adding

systemctl enable network-scripts

systemctl start network-scripts  

To the %post section of the template has corrected the issue.

It does seem a bit odd though that something like that wouldn't be included and enabled by default.

First, I think confignics has been superseded by confignetwork; Regardless of that, you should only call one of them.

Second, are you using the ?nics? table? If not, please look into it. If yes, please show the settings for the node.

Subject: [xcat-user] Node nic config error during install

 

xCAT 2.16.1

CentOS 8.3

 

When the node finishes installing, the network doesn't come up.

 

The postscript is set to do it.

postscripts=syslog,remoteshell,syncfiles,confignics --ibaports=1,confignetwork -s

However, it doesn't.

 

If I attempt to run it manually, I get this error:

[root@c001 xcatpost]# /xcatpost/confignetwork -s
[I]: NetworkManager is active
[E]:Error: Can not determine proper install nic.
[I]: There is no other nic device to configure.

 

There is an ifcfg-eno1 file present, which is wrong:

[root@c001 network-scripts]# cat ifcfg-eno1
# Generated by parse-kickstart
TYPE=Ethernet
DEVICE=eno1
UUID=3f02c4a7-daf5-4404-8fe7-43492454ef92
_ONBOOT_=yes
BOOTPROTO=dhcp
IPV6INIT=yes
PROXY_METHOD=none
BROWSER_ONLY=no
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME="System eno1"

 

There is also an ifcfg-xcat-eno1 file, which is what should be configured.

[root@c001 network-scripts]# cat ifcfg-xcat-eno1
DEVICE=eno1
IPADDR=172.16.0.26
NETMASK=255.255.252.0
BOOTPROTO=none
_ONBOOT_=yes
NAME=xcat-eno1
AUTOCONNECT_PRIORITY=9
MTU=1500

 

2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 18:03:73:1c:77:b8

 

lsdef for the node shows these:

ip=172.16.0.26
mac=18:03:73:1c:77:b8

 

Any idea why this is failing?

 

This is a first attempt to get this set up on 8.x
