We'd like to use short hostnames as all of our keys in the xCAT tables, to save
typing, and have the FQDN assigned as the hostname after an install.
We could fix the hostname with a postscript, or perhaps a Kickstart statement,
however we'd prefer to have it done more transparently.
It would be great if we could use something like a regex in
"network.nodehostname="/\z/.nyc.desres.deshaw.com/" to do this automatically:
[root@drdkvm0003 dump1]# lsdef -t network 149_77_52_0-255_255_254_0
Object name: 149_77_52_0-255_255_254_0
ddnsdomain=nyc.desres.deshaw.com
domain=nyc.desres.deshaw.com
dynamicrange=149.77.53.132-149.77.53.191
gateway=149.77.52.10
mask=255.255.254.0
mgtifname=!remote!
nameservers=149.77.52.53,149.77.52.35,10.232.15.130
net=149.77.52.0
nodehostname=/\z/.nyc.desres.deshaw.com/
ntpservers=149.77.52.24,149.77.52.41,149.77.52.138,149.77.52.129
tftpserver=149.77.53.252
But this doesn't seem to have any effect on the DHCP host-name entry generated
in the leases file, or on the "HOSTNAME=develkv8" entry put in
/etc/sysconfig/network after the install.
BTW. We do have the FQDN listed first in /etc/hosts and DNS:
[root@develkv8 ~]# hostname
develkv8
[root@develkv8 ~]# host 149.77.53.121
121.53.77.149.in-addr.arpa domain name pointer develkv8.nyc.desres.deshaw.com.
[root@develkv8 ~]# grep develkv8 /etc/hosts
>>> 149.77.53.121 develkv8.nyc.desres.deshaw.com develkv8 #
>>> row 0 rack 0 rank 0
Is there a transparent way to do this?
Thanks.
