This scsctl initialization step builds a custom configuration file for DHCP and restarts the service using the pattern determined in network planning for the site. Changes in the configuration file specify pools and ranges which DHCP is to manage, as well as other DHCP response data to be used with PXE booting storage nodes.
The Swarm network requires an upper or lower (or both) reserved range defined to configure DHCP. At least one of these parameters must be provided.
| The number of IP addresses to reserve in the lower subnet range (default is 0). |
| The number of IP addresses to reserve in the upper subnet range (default is 0). |
For example, set the DHCP reserve lower range.
scsctl init dhcp --dhcp-reserve-lower 30
The configuration values used for DHCP reserve lower or upper range always come from the network planning.
See additional Swarm configuration for setting up more configuration for DHCP.
If needing to configure the MTU value that DHCP serves to storage nodes, please see SCS Administration - Swarm (Internal) Network MTU.
Next, install Swarm license.
