We are not able to add AWS nodes in existing production cluster (primary site- OVA appliances). In the cluster configuration after selecting "Subscribe to active cluster" we are getting below error:
PAM-CMN-1582: The hardware platform of the cluster (onpremises), does not match the hardware platform of this node (aws).
Starting in CA PAM 3.3.x and higher we do allow inserting new nodes into a running cluster and additionally adding a new secondary site but you cannot read the configuration from a node that does does share the same hardware configuration.
Release : 3.3 and higher
Component : PRIVILEGED ACCESS MANAGEMENT
You need to read the configuration from a member of a site with the same hardware configuration as the node you are adding.. If you do not already have a site with the same hardware configuration you need to follow the steps to "add" a new site to the existing cluster which can be done from the primary site cluster configuration (see "Add a Cluster Site" in the current online documentation).
