This task verifies the state of the servers to ensure that the system is ready for the configuration of features.
As part of the pre-check activity, a health check is performed to validate the state of the system and to avoid a stale state. Not validating the system state can lead to irrecoverable failures in the system. This makes the health check very important.
The health check performs the following actions:
Verifies that the services important for the installation, such as Kerberos, Samba, and NMB services, are running on the remote server.
Verifies that the DNS service is active on the server configured as the DNS server.
Verifies that all the servers that are part of the replica ring are active and that time is synchronized among the servers.
Verifies that the version of eDirectory on the server where installation is done is 8.8 SP2 or later.
In a name-mapped installation scenario, it checks to see if the server contains any existing DSfW-specific objects.
Triggers a purge on the remote server to clear deleted objects.
