Before you start configuring the Cloud Integrated Storage (CIS) or infrastructure services, ensure that the following prerequisites are met:
Ensure that a minimum of 16 GB of RAM is configured for CIS or infrastructure services to function normally.
The eDirectory schema for CIS must be extended so that the CIS server is successfully configured. If eDirectory schema is not extended for CIS, execute the cis.sch file on the OES server to enable the schema. For more information about how to run the script, see CIS Configuration Fails With an Error. If OES Storage Service (NSS) pattern is selected during installation, the eDirectory schema is automatically updated.
Ensure that /etc/resolv.conf is configured with the appropriate DNS entry so that the OES server, CIS, and its infrastructure services (Elasticsearch, ZooKeeper, and Kafka) are mutually resolvable.
The OES server certificate must include DNS name in the Subject Alternative Name (SAN).
Ensure that the database is installed and configured. For information on how to install and configure MariaDB, see Section B.0, Installing and Configuring MariaDB. If you want to use already configured database (MariaDB or MS SQL) with CIS, ensure that the database is up and running.
While upgrading from OES 2018 to OES 2018 SP3, ensure that the CIS pattern is not installed.
