Well first I am very very very sorry, because I have many questions,
but the link is not very clear to me, sorry again for my stupid questions.
I am trying to compose the file, but I have some questions not clear to me:
1- I understood that the new installation requires 3 controller node, what I see in
the link you sent me earlier, is states that the undercloud node is different node from
the controller nodes? Does it mean that I need 3 controller nodes + the undercloud node,
or I need 2 controller node + the undercloud node?
Undercloud node is different from the overcloud controller nodes. You
require 3 overcloud controllers when you deploy a HA control plane. In
that case yes, you need the undercloud + 3 controller nodes deployed
by the undercloud.
2- I have a node which I will use as a storage HW, but this node
can be connected to the PXE/Boot VLAN over a trunk interface, that mean it cannot be PXE
booted (I cannot PXE boot over a trunk interface as far as I know), it means I need to
install it separately configure the VLANs on this interface, and then let it join the
controller, is that possible?
PXE boot can work on a trunk interface as long as it's running over
the native vlan.
3- Finally for the Jason file itself here is a sample section:
{
"pm_type":"pxe_ipmitool",
"mac":[
"00:17:a4:77:78:30"
],
"cpu":"2",
"memory":"49152",
"disk":"300",
"arch":"x86_64",
"pm_user":"admin",
"pm_password":"password",
"pm_addr":"10.0.0.8"
},
a- I understand that the MAC address for the PXE boot interface for the
different nodes in the overcloud is that correct?
Yes, that's correct.
b- In the link it says that pm_addr is " node BMC IP
address ", but that is not clear to me, does it mean it is the IP of the
"local_ip" in the undercloud.conf, which is always the IP of the eth1 of the
undercloud node in the link you sent me earlier, or it is not the case?
This is the IPMI address of the server used for power operations.
c- In the link it say that pm_user, and pm_password are
"node BMC credentials" , are these the credentials I need to configure manually
per node, do they need to be the same for all nodes? Or they are already defined in the
stackrc file?
Again, these are the IPMI credentials used for logging into pm_addr .
They need to be configured on the servers to be able to manage them.
Thanks,
Ashraf
