[DRAFT] Configure DHCP

Using the pattern determined in network planning for the site, this scsctl initialization step will build a custom configuration file for DHCP and restart the service. 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.

To configure DHCP, refer to the following steps:

1. Set DHCP reserve lower range.

   scsctl init dhcp --dhcp-reserve-lower=30 
   DHCP config updated

2. Set the minimum size of the disk supported by the Swarm cluster. For example, the Swarm cluster supports a minimum of 16 GB disk size.

   scsctl storage config set -d ​​"disk.minGB=16" 

3. Enable the nodeExporter for Prometheus.

   scsctl storage config set -d "metrics.enableNodeExporter=true" 
   scsctl storage config set -d "metrics.nodeExporterFrequency=120"
