The Viewing Nodes panel in the SAN Volume Controller Console displays
details about all the nodes in a cluster. From this panel, you can
work with configured nodes or view detailed configuration information
for them.
Attributes
The
following attributes are displayed in the table:
- Select
- Allows you to select the node to use to perform an action from
the task list.
Note: Only one row can be selected at a time.
- ID
- Displays the system-assigned ID of the node.
- Name
- Displays the name that is assigned to this node. If you have not
yet assigned a name, a default name is assigned. The default name
is the string node, which is followed by the system-assigned
ID. You can click the link in this column to display detailed information
about the node.
- State
- Displays the current state of the node. The following values are
possible:
- Adding
- Indicates that the node has been added to the cluster but is not
synchronized with the state of the cluster.
- Deleting
- Indicates that the cluster is in the process of deleting the node.
Any VDisk-to-host mappings and copy services interactions are being
deleted.
- Flushing
- Indicates that the node is clearing its cache.
- Online
- Indicates that the node is operational, assigned to a cluster,
and has access to the fibre-channel storage area network (SAN) fabric.
- Offline
- Indicates that the node is not operational. The node has been
assigned to a cluster but is not available on the fibre-channel SAN
fabric. Run the directed maintenance procedures to determine the problem.
- WWNN
- Displays the worldwide node name.
- I/O Group
- Displays the name of the I/O group that this node belongs to.
The default name is the string io_grp, which is followed
by the system-assigned ID.
- Config Node
- Indicates if this node is the configuration node for the cluster.
The following values are possible:
- iSCSI Name
- Displays the iSCSI qualified name (IQN) for the node. For SAN Volume Controller nodes
this is always iqn.1986-03.com.ibm:2145.<cluster
name>.<node name>, where <cluster
name> and <node name> depend on
the values configured for the cluster.
- iSCSI Alias
- Displays the alias name for the node which identifies it to the
iSCSI-attached host. The alias name can consist of any printable ASCII
character, but cannot begin or end with a space. An alias name cannot
exceed 79 characters.
- Hardware Model
- Displays the current model type of the hardware. The following
values are possible:
- CF8
- 8A4
- 8G4
- 8F4
