Create Nutanix Phoenix ISO for foundation (AHV)/ expand existing cluster with new nodes

Nutanix has provided multiple way to do the foundation for the nodes which comes without software . these blogs Is best suitable if you already have the nutanix cluster and wanted to expand with the new nodes.

Phoenix .ISO can be created from the existing cluster , phoenix .ISO will have hypervisor information + CVM which means one setup for both the installation.

First you do SSH to one of the CVM of existing cluster the find the AOS files

nutanix@NTNX-19SM3E030323-A-CVM:$ ls


Run the following command to create tar file , as AOS files would be in extracted format

nutanix@NTNX-19SM3E030323-A-CVM:$ tar -cvzf /home/nutanix/foundation/nos/$(< /etc/nutanix/release_version).tar.gz -C ~/data/installer/ $(< /etc/nutanix/release_version) –transform=”s:^$(< /etc/nutanix/release_version)/:install/:” –show-transformed-namesel7.3-release-euphrates-

Now once you have the tar file , run the following command to create the phoenix iso files

nutanix@NTNX-19SM3E030323-A-CVM: ~/foundation/bin$ ./generate_iso phoenix –aos-package=/home/nutanix/foundation/nos/el7.3-release-euphrates- –kvm-from-aos –temp-dir=/home/nutanix/foundation/tmp

Now the download the files from the location

nutanix@NTNX-19SM3E030323-A-CVM:$ ls -ltrh

total 6.1G

nutanix@NTNX-19SM3E030323-A-CVM:$ l

Configure the IPMI ipaddress for the new nodes and boot the nodes with the Phoenix ISO

Once the foundation is done for the all the nodes , you can discover the nodes from prism to expand the cluster
