Ready ports match connected ports?

YES

Network reachable?

YES

Host known?

YES

For cost-based failover groups, edit the configuration files and verify the port cost for both ports.

If the active port priority is greater than the intended port priority, modify the priority value for the intended port (making it greater than the current active port).

If the active port cost is less than the intended port cost, modify the cost value for the intended port (making it less than the current active port).

For more information, see “Editing Configuration Files for Failover Groups” (page 107).

Verify that the ready ports are identical to the connected ports by using NO the following command:

# lanadmin -x -i linkAggPPA

where linkAggPPA is the failover group instance number.

If the ready ports are different from the connected ports, some ports are disconnected from the current active port. If the current active port is not the intended active port, do the following:

1.Edit the configuration file and remove the port.

2.Issue the following commands:

#lanqueryconf -s

#lanapplyconf

For more information, see “Editing Configuration Files for Failover Groups” (page 107).

If a remote host's network is not reachable, the following message is NO displayed in response to the ping command:

network is unreachable

Complete the following steps:

1.Ensure that the network devices are configured properly on the local host, using the netstat -icommand.

2.Verify that the routing tables on the local host are correct, using the netstat -rcommand.

If a host is not known, the following message is displayed:

NO unknown host

Complete the following steps:

1.Verify that the user is trying to reach the remote host using a valid host name.

2.Verify that the remote host is in another name domain and that the user specified the full domain name.

3.If your site uses the Domain Name System (DNS) for name-to-address translation, look in the /etc/nsswitch.conf file to see if nis is specified as a service for the hosts database entry. If it is not, add it. Also, verify that the DNS service has information about the remote host.

4.If your site uses the NIS name service for name-to-address translation, look in the /etc/nsswitch.conf file to see if nis
