The OpenShift documentation states that IPAM is a networking requirement for installing on Nutanix:
https://docs.openshift.com/container-platform/4.13/installing/installing_nutanix/preparing-to-install-on-nutanix.html#installation-nutanix-installer-infra-requirements-networking_preparing-to-install-on-nutanix
"You must use AHV IP Address Management (IPAM) for the network and ensure that it is configured to provide persistent IP addresses to the cluster machines" 

A mutual customer found out from Nutanix support that IPAM is no longer required starting with OCP 4.13.2. We were able to find out that there was a security advisory included with 4.13.2: https://access.redhat.com/errata/RHSA-2023:3367 which includes this bugfix: https://issues.redhat.com/browse/OCPBUGS-10493 
The bugfix above appears to eliminate the IPAM networking requirement (assuming DHCP is enabled). Please confirm if this understanding is correct and if so it would be appropriate to update the documentation to reflect this change.

 

4.13.2+

1. Review https://docs.openshift.com/container-platform/4.13/installing/installing_nutanix/preparing-to-install-on-nutanix.html#installation-nutanix-installer-infra-requirements-networking_preparing-to-install-on-nutanix 

Current documentation states: "You must use AHV IP Address Management (IPAM) for the network and ensure that it is configured to provide persistent IP addresses to the cluster machines"

Updated documentation should reflect that starting with 4.13.2 either IPAM or DHCP are required to be enabled.
