I have already checked the following:

✅ DHCP is disabled for all storage adapters

✅ VLAN is set to 0

✅ Management IP is manually assigned

But the errors persist.

Questions:

1. Why does the system detect DHCP/manual IP addresses on storage adapters when DHCP is already disabled?
2. Is manual IP assignment acceptable for Storage Network, or does it require DHCP?
3. What are the exact subnet alignment requirements for Management IP and Infrastructure IP Pool?

Any help would be greatly appreciated! Thanks.
