Use the Viewing Node Ethernet Port Details panel in the SAN Volume Controller Console to
display detailed information about node Ethernet ports. A node Ethernet
port represents an iSCSI port on an SAN Volume Controller node.
Attributes
The
following attributes are displayed:
- Node ID
- Displays the system-assigned identifier for the node.
- Node Name
- Displays the name of the node.
- Port
- Displays the name of the Ethernet port for
the node. Select the port name to display detailed information about
the node Ethernet port.
- State
- Displays the current state of the node Ethernet port. The following
values are possible:
- Online
- Indicates that the node Ethernet port is operational, the node
is online, and the port is connected and operational on the TCP/IP
network.
- Offline
- Indicates that the node Ethernet port is not operational because
either the node is offline or there is connection problem to the TCP/IP
network.
- Not Configured
- Indicates that the node Ethernet port is currently not configured
with an IP address.
- Failover Active
- Indicates whether node port IP address failover is active for
the node Ethernet port. Node port IP failover maintains consistent
connection between the cluster and the iSCSI-attached host if the
node which the host is attached to fails. The iSCSI hosts connect
to SAN Volume Controller through
the node port address for that node. If that node fails, the address
becomes unavailable, and the host loses communication with SAN Volume Controller and
access to data. To allow hosts to maintain access to data, the node
port IP address for the failed node is transferred to the partner
node. The partner node handles requests to both its own node port
IP addresses and node port IP address for the failed node. This
process is known as node port IP failover. In addition to the node
port IP address, the iSCSI name for the node is also transferred to
the partner node. When the node recovers, the node port IP address
and the iSCSI name return back to the original node.
Node port IP
failover only occurs if a node goes offline or is deleted from the
cluster and does not occur if the Ethernet connection is lost to the
port. Since an I/O group contains the maximum of two nodes in the
I/O group, each node acts as the partner node to the other node in
the same I/O group. Failover configuration is activated on the local
node until the partner node comes back online and activates the settings.
- The following values are possible:
- Yes
- Indicates that node port IP failover is active.
- No
- Indicates that node port IP failover is not active.
- MAC
- Displays the Media Access Control (MAC) address for the Ethernet
port.
- Speed
- Indicates the speed of the node Ethernet port. The following values
are possible:
Note: The speed value is only available if a cable is connected
to the switch. If the cable is not connected to the switch, the speed
value displays "-".
