Re: [xcat-user] How to create and deploy an xCAT Service Node

Hi Wang Xiaopeng (I apologize if I got your name wrong before), You said: SN cannot work without MN since there's only one database which is running on MN. If MN is down you cannot run lots of commands on SN. In fact xCAT does NOT recommend to run any command on SN. Will DNS and DHCP still work

[xcat-user] networks.dhcpserver

Hi all, What is the purpose of the networks.dhcpserver entry in relation to service nodes? What configuration files will contain this entry when it is set? Thanks! -- CenturyLink Cloud: The Leader in Enterprise Cloud

Re: [xcat-user] How to create and deploy an xCAT Service Node

DNS and DHCP will still work from the Service Node, if setup correctly. In other words, you have configured the service node as the DNS server and/or DHCP server for the nodes and there is no requirement on the Management Node for dns or dhcp. You will not be able to run any xcat

Re: [xcat-user] networks.dhcpserver

Thanks Lisa, Yeah I get that, I am just wondering *why* it is needed - service node pools by their very definition can share DHCP requests and all answer a DHCP request for any node. Why does networks.dhcpserver need to be set to a single IP in that

[xcat-user] Policy table question

Hi all, What are the default policy attributes service nodes should have in the policy table for xCAT 2.8+? Unless I specifically add, for example, rpower to the below list, I get a permission denied when a compute node is configured to a service node. If the compute node is not configured

[xcat-user] Node discovery for VMs in VMWare

Hello all, I would like to provision some new nodes in my xCAT cluster inside VMWare but I just realized that the way xCAT has identified and discovered my nodes in the past has been by dedicated physical port numbers on the switches as defined in the xCAT switch database table. That is not a
