Hi Kevin,
Thanks for sharing your node config. So, I was able to build the node
finally, I had to do 'nodediscoverdef -u
4C4C4544-0039-3110-804A-B6C04F544B31 -n n02' . When you say, 'assign an IP
address..." did you mean assigning a BMC IP? Also, I don't fully
understand the chain concept yet, as I have not read much about it. I will
start reading about. But you know, my builds are stateful as this time, so
I am not sure if chain will help me with anything.
I do have another issue that I just noticed with the imaged node. the node
that I built, I set up a static IP for it in the /etc/hosts file.
here is my /etc/hosts file:
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
localhost6.localdomain6
10.1.1.20 xcatmaster xcatmaster.localdomain
#
10.1.1.81 n01 n01.localdomain
*10.1.1.82 n02 n02.localdomain*
10.1.1.83 n03 n03.localdomain
so, on n02, when it was built, /etc/sysconfig/network-scripts/ifcfg-eth0
file has the following:
DEVICE="eth0"
*BOOTPROTO="dhcp"*
HWADDR="00:24:E8:36:AD:95"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="3e48a0e7-0691-4fb8-b921-727ebe37f257"
Note, BOOTPROTO is set to 'DHCP', I thought xcat will add 10.1.1.82 as a
static IP(?). I am sure that I am missing something, just don't know yet
what I am doing wrong here.
