Some Swarm configuration settings are site-specific and related to: 

  • DNS settings - These are required for DHCP configuration.

  • Administrative username and password - SCS does not accept any unauthenticated commands once the administrator username and password are set. 

  • Disk encryption settings - These settings are related to “Encryption at Rest” and should be skipped unless specified by DataCore Support. 

Info

This process is interrupted to allow scsctl to be configured with the administrative username and password for future interactions with SCS once the administrative username and password are set. To perform this configuration run: 

scsctl auth login --user [administrative user name] 

This command securely prompts the administrative password and authenticates to SCS. Re-run the configuration scan command to resume once the CLI is logged in:

scsctl diagnostics config scan_missing

Finalize configuration settings

Note

Input characters such as ‘admin.userName’, ‘admin.password’, ‘encryptionKeys’ are hidden when configuring Swarm settings. Best practice is to copy and paste inputs from a raw text editor to prevent any transcription or transposition errors. 

  1. Run scsctl diagnostics config scan_missing

Instances cannot currently inherit these from the group (since they have not been defined at the group level), so these settings must instead be defined for each instance! 

If any new instances are added, please define these settings, or define them at the group level to apply to all instances. Best practice is to define them at the group level if possible. 

  2. Press ‘Enter’ to apply settings when prompted for the DNS servers.
