The configuration itself is correct? range.conf and dhcpd-static-hosts.conf is
the same on both hosts.
Primary:
option domain-name-servers 8.8.8.8
option time-servers 10.91.120.1
option option-222 code 222 = ip-address;
option option-222 10.91.120.48;
ddns-update-style none;
default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;
failover peer "dhcp-failover" {
