Some Swarm configuration settings are site-specific and related to:
DNS settings - These are required for DHCP configuration.
Administrative username and password - Once the administrator username and password are set, SCS will not accept any unauthenticated commands.
Disk encryption settings - These settings are related to “Encryption at Rest” and should be ideally skipped unless specified by DataCore Support.
Info
Once the administrative username and password are set, this process will be interrupted to allow scsctl to be configured with the administrative username and password for the future interaction with SCS. To perform this configuration, run:
scsctl auth login --user [administrative user name]
This command will securely prompt the administrative password and authenticate to SCS. Once the CLI is logged in, re-run the configuration scan command to resume:
scsctl diagnostics config scan_missing
Finalize configuration settings
Note
When configuring Swarm settings, input characters are hidden such as ‘admin.userName’, ‘admin.password’, ‘encryptionKeys’, etc. It is advised to use inputs on a raw text editor and do copy & paste to prevent any typo mistakes.
Run
