where port is the port instance number and xxx is the failover
group instance number. The message indicates the reason the port
is not connected with the others.
For cost-based failover groups, enter the following command:
# nwmgr -s -A links=port -A port_pri=value -A
port_cost=value -c lanxxx
The message indicates the reason the port is not connected with
the others.
3. Save the current configuration with the following command:
# nwmgr -s -A all --fr cu --sa -S apa
If a remote host's network is not reachable, the following message is
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 -i command.
2. Verify that the routing tables on the local host are correct, using
the netstat -r command.
If a host is not known, the following message is displayed:
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
is specified as a service for the hosts database entry. If it is not,
add it. Also, verify if the NIS service has information about the
remote host.
5. If your /etc/nsswitch.conf file lists files as the only
name-to-address translation mechanism, the /etc/hosts file
does not have information on the remote host. See nsswitch.conf(4)
for more information.
If a remote host is not reachable, the following message is displayed:
host is unreachable
Complete the following steps:
1. Inspect the cabling between the local host and the link partner.
