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

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:
| Code Block | ||
|---|---|---|
| ||
scsctl platform config set -d "admin.userName={existing cluster administrative user name}" --allow-notification-failures |
| Info |
|---|
InfoAny time the administrative credentials are updated, you will need to run the following to re-authenticate
This command securely prompts the administrative password and authenticates to SCS. |
| Tip |
|---|
Next, Configure DHCP. |
