Chapter 2: SHA Troubleshooting 2.2.43 Warning: Incorrect network configurations [Details: The network settings-including DHCP, Gateway, and DNS Server-of the following interfaces on the active and passive servers are not identical: LAN X.] Warning Incorrect network configurations. Details: The network settings-including DHCP, Gateway, and DNS Server-of the following interfaces on My_Active_Hostname (active server) and My_Passive_Hostname (passive server) are not identical: LAN X. Suggestion: Go to Network to modify network settings. Description The network settings (DHCP, gateway, and DNS server) of the cluster interface LAN X on the active and the passive servers are inconsistent. Once the service is switched over, services using LAN X may be affected. Cause The active and passive servers are each connected to different DHCP servers, resulting in different network settings (gateway address or DNS server address) on each server. Resolution • If LAN X is using DHCP IP, edit the network settings on the DHCP server so that the gateway addresses or DNS server addresses that the active and passive servers obtain from the DHCP server are the same. • If LAN X is using a static IP, go to Network > Manage Network Interface > Configure Server Network, and select Use manual configuration. Then, modify the network settings so that the gateway addresses and DNS server addresses are the same for both the active and passive servers. 2.2.44 Warning: Incorrect network configurations [Details: The primary cluster interface LAN X on the active server and the passive server must be assigned a static IP address.] Warning Incorrect network configurations. Details: The primary cluster interface LAN X on My_Active_Hostname (active server) and My_ Passive_Hostname (passive server) must be assigned a static IP address. Suggestion: Go to Network and assign static IP address for primary cluster interface LAN X on My_Active_Hostname (active server) and My_Passive_Hostname (passive server). Description The IP addresses set on primary cluster interface LAN X for the active and passive servers are not static IP addresses. Therefore, the two servers will not be able to communicate via the primary cluster interface. Cause This error usually occurs after the two servers' hard disks have been migrated. When this is done, LAN 1 will be automatically set to DHCP, where LAN 1 is the primary cluster interface. Resolution Go to Network > Manage Network Interface > Configure Server Network, select Use manual configuration and modify the network settings to assign a static IP address for the primary cluster interface on each server. 39
