Some Swarm configuration settings are site-specific and related to:
DNS Settings - These are required for DHCP configuration.
Disk Encryption Settings - These settings are related to “Encryption at Rest” and should be skipped unless specified by DataCore Support.
Finalize Configuration Settings
Note
Input characters such as encryptionKeys are hidden when configuring Swarm settings. The best practice is to copy and paste inputs from a raw text editor to prevent any transcription or transposition errors.
Run
scsctl diagnostics config scan_missing

Notes on Administrative User Name
If SCS is being installed with an existing Swarm storage cluster, then care must be taken to ensure that the SCS administrative user name matches the administrative user name within the storage cluster. This must occur before booting any nodes with SCS. To update the administrative user name at this point:
scsctl platform config set -d "admin.userName={existing cluster administrative user name}" --allow-notification-failures
Info
Any time the administrative credentials are updated, you will need to run the following to re-authenticate scsctl with the API server.
scsctl auth login --user [administrative user name]
This command securely prompts the administrative password and authenticates to SCS.
Next, configure DHCP.
