It’s more fundamental than xCAT. The _ (underscore) is not allowed in DNS at

Subject: [xcat-user] xCAT node name invalid characters or hard codelimitations ?
Hi ,Dear
I setup the xCAT and see below failed info when try to makedns –n ,can
anybody help to take a look ,thanks
Ignoring line 172.32.44.178 cfdv3_192g_012-bmc cfdv3_192g_012-bmc.cluster in
/etc/hosts, names cfdv3_192g_012-bmc cfdv3_192g_012-bmc.cluster contain
invalid characters (valid characters include a through z, numbers and the '-',
but not '_'
makedns -n ,
[root@mgt ~]# makedns -n
Ignoring line 172.29.101.6 n05_xcc n05_xcc.cluster in /etc/hosts, names
n05_xcc n05_xcc.cluster contain invalid characters (valid characters include a
throug h z, numbers and the '-', but not '_'
Handling n01-xcc in /etc/hosts.
So question is
1 : is the ‘_’ not allow to use in the compute name ?
2: is there any way to make it possible to use the ‘_’ in compute name in xCAT ?
