In the Modify Group screen you can change the node type assigned to a group of nodes and, in some cases, the system they belong to. PUT enforces certain restrictions to prevent incorrect group changes. You can only modify nodes from one group at a time, however, not all nodes have to be selected for modification. A node can always be moved back into its original system and group.
-
To change a node to a new type, select one or more nodes in the same group from the list on the right side of the screen and click Modify Group.
The Modify Group screen displays only applicable choices.
-
Select the appropriate options as described in the following graphic and table:
Option Choices Description System Node groups are associated with a system based on BYNET connectivity. All nodes interconnected via the BLLI interface are placed into the same system based on what the Find All Systems step discovers. A multi-node system can have multiple node groups. Non-BYNET connected nodes are typically represented as a single-node system unless the node type is UNKNOWN. On the Modification screen, a New System can be defined only when node groups containing UNKNOWN types are selected. When multiple UNKNOWN nodes are selected they can be moved to an existing system or new system. New systems are always assigned the next available system number. This is used more for staging new systems and is not often used in the field.
Group Each node is initially placed in a group based on installed software. When changing a group’s node type, you must define a New Group unless a valid existing group with the same type and identical software is available. Node Type When changing a node type, a new group must be created if there is no existing group that matches the desired node type. PUT displays a warning if an invalid selection is made. Node types are:- ADB - Aster (generic) nodes cannot be changed to another type, however, this choice is available when an UNKNOWN node is selected.
