The lsnode command returns a concise list or a detailed view of nodes visible to the cluster.
The list report style can be used to obtain two styles of
report:
- A list containing concise information about all the nodes on a cluster. (Each entry in the list corresponds to a single node.)
- The detailed information about a single node.
Syntax
>>- svcinfo -- -- lsnode -- ------------------------------------> >--+--------------------------------+-- --+----------+-- -------> '- -filtervalue -- attrib=value -' '- -nohdr -' >--+-----------------------+-- -- --+-----------------+---------> '- -delim -- delimiter -' '- -filtervalue? -' >--+---------------+------------------------------------------->< +- object_id ---+ '- object_name -'
Parameters
- -filtervalue attrib=value
- (Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are returned. If a capacity is specified, the units must also be included.
- Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcards with the SAN Volume Controller CLI:
- The wildcard character is an asterisk (*).
- The command can contain a maximum of one wildcard.
- When using a wildcard, you must enclose the filter entry within
double quotation marks (""), as follows:
svcinfo lsnode -filtervalue "name=md*"
- -filtervalue?
- Displays a list of valid filter attributes for the -filtervalue attribute=value parameter.
The valid filters for the svcinfo lsnode command are:
- node_name
- id
- status
- IO_group_name
- IO_group_id
- name
- hardware
- -nohdr
- (Optional) By default, headings are displayed for each column
of data in a concise style view, and for each item of data in a detailed
style view. The -nohdr parameter suppresses
the display of these headings.Note: If there is no data to be displayed, headings are not displayed.
- -delim delimiter
- (Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
- object_id | object_name
- (Optional) Specifies the name or ID of an object. When you use this parameter, the detailed view of the specific object is returned and any value that is specified by the -filtervalue parameter is ignored. If you do not specify the object_id | object_name parameter, the concise view of all objects matching the filtering requirements that is specified by the -filtervalue parameter are displayed.
Description
This
command returns a concise list or a detailed view of nodes visible
to the cluster. Table 1 provides
the possible values that are applicable to the attributes that are
displayed as data in the output views.
To determine a node's WWPNs, enter the following
command:
svcinfo lsnode
Note: Record
the node name or ID because you use this value in the next step.
For
the node or nodes in question, issue the following command: svcinfo lsnode node_name | node_id
where node_name | node_id is the node name or ID.Note: Record the four port IDs
(WWPNs).
Attention: If the node is in the adding
state, the WWPN is displayed as 0000000000000000. Once the node has
successfully become a member of the cluster, the state changes to
online and the WWPN is displayed correctly.
