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. 

  1. Run

    scsctl diagnostics config scan_missing

     

    ======================================================================================================  Component: network_boot  ----------------------------------------------  Name: network.dnsServers  Type: array[str]  Description: Required. DNS servers to be used.  ----------------------------------------------  Component Group: network_boot/192.168.9.0x24.network_boot.scs-lab1.datacore.internal [DEFAULT GROUP]  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. Click ‘Enter‘ to apply the settings when prompted for the DNS servers.

    ----------------------------------------------  Name: network.dnsServers  Type: array[str]  Description: Required. DNS servers to be used.  ----------------------------------------------  Missing setting: network_boot/network.dnsServers  Where would you like to update this setting? > As a default at group level    For each instance in the group    Skip this setting for now 

  3. Provide the DNS servers.

  4. Click ‘Enter‘ to apply at the group level when prompted for the DNS domain.

  5. Set the DNS domain.

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:

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.
