If your Configuration Storage server or any of your array members will not be in a single domain or in a domain with trust relationships, you will need to:
- Create and export a server authentication certificate for the
Configuration Storage server, and ensure that the certificate
export file is accessible to the computer that will be the
Configuration Storage server during the installation process.
- Install the root certificate for the certification authority
(CA) that issued the server certificate for the Configuration
Storage server on your array member servers.
