Working with node groups

You can use a command line interface, SMIT panels, and the SP Hardware Perspective for working with node groups. Refer to PSSP: Command and Technical Reference for a complete description of commands. For information on using the SP Hardware Perspective to create and manage node groups, refer to the online help.

You can use the following commands to create, modify, and delete node groups:

ngcreate

Creates and optionally populates a named node group.

ngnew

Creates new node groups in persistent storage.

ngaddto

Adds specified nodes and node groups to named node group.

ngdelfrom

Removes specified nodes and node groups from named node group.

ngdelete

Removes node groups from persistent storage.

ngclean

Removes nodes and node groups that do not currently exist from specified node groups or every node group in the current system partition.

You can use the following commands to display node group information to standard output:

ngresolve

Displays a list of nodes in the node group.

nglist

Writes a list of all persistent node groups.

ngfind

Writes a list of all node groups containing the supplied node or node group.

TYPE

smit nodegroups

• The Node Group Information menu appears.

SELECT

Partition Node Groups OR System Node Groups

• The Partition Node Groups or System Node Groups panel appears.

To access SMIT panels (using the fastpath invocation) for examining existing node groups:

TYPE

smit list_nodegroup

• The List Node Group Database Information menu appears.

SELECT

Examine Partition Node Groups OR Examine System Node Groups

• The Examine Partition Node Groups or Examine System Node Groups panel appears.

To access SMIT panels (using the fastpath invocation) for deleting node groups:

TYPE

smit delete_nodegroup
