admin network configuration

SUSE OpenStack Cloud
1

Hi,

Can someone please clarify my doubts regarding creating network.json file. Thank you in advance.

  1. I will be adding my existing SLES severs to the cloud, this is the only way i will be provisioning servers, and i won’t be using PXE/DHCP method of provisioning. In that case, how the admin network should be defined in the network.json file?

  2. I do not understand the various IP range sections under admin network. The ranges like admin, dhcp, host, and switch, what are these exactly for?

“ranges”: {
“admin”: {
“end”: “192.168.124.11”,
“start”: “192.168.124.10”
},
“dhcp”: {
“end”: “192.168.124.80”,
“start”: “192.168.124.21”
},
“host”: {
“end”: “192.168.124.160”,
“start”: “192.168.124.81”
},
“switch”: {
“end”: “192.168.124.250”,
“start”: “192.168.124.241”
}
},

  1. If my admin, BMC, nova-external floating, and public network falls in the same network/VLAN (untagged), then do i still need to define the networks like “bmc”, “bmc_vlan”, “public” in the network.json ?

Thanks & Regards,

What do you mean by “existing SLES servers”? Are these currently
physical or virtual (not in OpenStack) servers running SUSE Linux
Enterprise Server (SLES) or do you mean you already have some existing
SUSE OpenStack Cloud nodes?

Yes you’ll still need them but you adjust values accordingly as per
https://www.suse.com/documentation/suse-openstack-cloud-7/book_cloud_deploy/data/sec_depl_inst_admserv_post_network.html

Hello Simon,

I would like to add SLES Physical Servers to the SUSE Cloud by running crowbar_register method. I will be using only this method of provisioning OpenStack nodes. In this case, i would like to understand how i need to define admin network in the json file. The admin IP ranges like host, dhcp, and switch won’t be use full at all to me, so i have a doubt whether i need to define them or not.

And, i won’t be using BMC network at all, in this case i would like to understand whether still i need to define bmc and bmc_vlan networks in json file.

Thanks & Regards,
Shashi Kanth.
