Resolving network errors

Use the following information and examples to resolve network errors that are
identified by the health system.
If a network is not attached to an interface, the health center monitors all ports and
logs and displays any port failures.
To stop monitoring an unused port, use the attachnw command to attach the
interface that corresponds to that port. After this command is issued, you must
manually mark the displayed error events for the unused port as resolved. You can
use the GUI system details panel to manually mark the events.
Whether a port is monitored depends on the attached network configuration and
the interface that is used for the management network. If an interface is not in use
by an attached network, the interface is monitored if it is used by the management
network.
See the following examples.
Scenario 1
lsnwgroup returns:
[root@kd66t4v.mgmt001st001 ~]# lsnwgroup

EFSSG1000I The command completed successfully.
and lsnwmgt returns:
[root@kd52v6k.mgmt001st001 ~]# lsnwmgt
Interface Service IP Node1 Service IP Node2 Management IP Network Gateway VLAN ID
ethX0
EFSSG1000I The command completed successfully.
None of the interfaces is attached and the management network uses interface
ethX0. If any ethX1 port cable is unplugged, the health center displays a failure
because no network is attached to an interface, which causes the system to monitor
all ports.
Scenario 2
lsnwgroup returns:
[root@kd52v6k.mgmt001st001 ~]# lsnwgroup
Network Group Nodes
DEFAULT
EFSSG1000I The command completed successfully.
and lsnwmgt returns:
