Re: [xcat-user] xCAT node name invalid characters or hard code limitations ?

[Yuan Y Bai]

Hi Peter,

 

1 : is the ‘_’ not allow to use in the compute name ?

'_' is not allowed to use in the compute name.

2: is there any way to make it possible to use the ‘_’ in compute name in xCAT ?

I suggest you not use '_' in compute name, '_' is invalid, if you change makedns code to let `makedns -n` works, I am not sure if other functions work well too. If you want to change code, you can enhance this line 440: "unless ($names =~ /^[a-z0-9\. \t\n-]+$/i) {"  in /opt/xcat/lib/perl/xCAT_plugin/ddns.pm

 

Best Regards

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 ?
