Description
Error Message
Veritas Cluster Configuration Wizard, the NIC selection phase gives an error "Unable to detect public network card with static IP address"
Cause
The above error can occur due to the following reasons
ISSUE 1. The Public NIC and HeartBeat NIC have DHCP enabled on them.
ISSUE 2. The Public/Heartbeat NIC are teamed, resulting in a logical interface for the NIC that has the same MAC as on of the teamed NIC. During the NIC discovery phase, the wizard detects the logical interface (teamed NIC) and owing to identical MAC Addresses fails to discovers the NIC.
Resolution
ISSUE 1: To identify if DHCP is enabled for NIC, run "ipconfig /all" and check for the attribute: DHCP Enabled for all the NIC.
You can choose to disable DHCP by manually assigning Private IP to the NIC participating in VCS LLT Setup or you can disable DHCP from registry by browsing to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces and navigate to the expected interface and set the "EnableDHCP" value to 0.
Take a reboot if needed and run ipconfig /all to confirm that DHCP is now disabled.
ISSUE 2: When using NIC teaming, LLT need to be configured manually using How to configure LLT over Ethernet with tagged VLAN interfaces or NIC Teaming that have the same MAC Addresses in a Microsoft Windows environment as the wizard would continue to detect the logical teamed interface.
