Hi,
My network topology has 3 networks:
* Service network: Internal infra like DHCP, DNS, Provisioning, centralized
auth services for compute nodes etc. (eth0 for all servers)
* Data network: All internet facing services run here (eth1 for servers)
* Management network: All IPMI interfaces (Titled ipmi for all servers)
For all compute nodes, the node name is associated with the data network
interface(eth1). A node configuration is as below:
[root@xcatmn01 xcat_prep]# lsdef compute1
Object name: compute1
arch=x86_64
currchain=boot
currstate=install rhels6.6-x86_64-compute
groups=compute,ipmi,all
initrd=xcat/osimage/rhels6.6-x86_64-install-compute/initrd.img
installnic=eth0
ip=10.4.4.50
kcmdline=quiet repo=http://!myipfn!:80/install/rhels6.6/x86_64
ks=http://!myipfn!:80/install/autoinst/compute1 ksdevice=eth0
kernel=xcat/osimage/rhels6.6-x86_64-install-compute/vmlinuz
mac=00:25:90:14:FA:30!compute1-s|00:25:90:14:FA:31!compute1|00:25:90:14:f3:49!compute1-m
netboot=xnba
nichostnamesuffixes.ipmi=-m
nichostnamesuffixes.eth0=-s
nicips.eth1=10.4.4.50
nicips.ipmi=10.1.240.50
nicips.eth0=10.2.72.50
nictypes.ipmi=Ethernet
nictypes.eth1=Ethernet
nictypes.eth0=Ethernet
nodetype=osi
os=rhels6.6
postbootscripts=otherpkgs
postscripts=syslog,remoteshell,syncfiles,create_root_authorized_keys
primarynic=eth1
profile=compute
provmethod=rhels6.6-x86_64-install-compute
This node should have just 3 names:
* compute1-s
* compute1
* compute1-m
These 3 are created correctly. However, a fourth entry is automagically
created by xCAT "compute1-eth1":
[root@xcatmn01 xcat_prep]# cat /etc/hosts |grep compute
10.4.4.50 compute1 compute1.poc.lzd.co compute1-eth1
10.1.240.50 compute1-m compute1-m.poc.lzd.co
10.2.72.50 compute1-s compute1-s.poc.lzd.co
I don't want this entry created. Is there some way to enforce this?
