The HCP installation is performed from the node with the highest last octet in its back-end IP address.
For example, if the four back-end IP addresses for a system are 172.21.150.150, 172.21.150.151, 172.21.150.152, and 172.21.150.153, perform the HCP software installation on node 172.21.150.153.
Note: Although you can install the HCP system, you cannot enable data-at-rest encryption (DARE). DARE encrypts data on primary storage and data tiered to external storage pools. If you plan to use DARE features, contact your authorized HCP service provider before performing the software installation.
