In the example shown in FIGURE 1-3 , system board #2 is deleted from domain A and
added to domain B. In this way, the physical configuration of the hardware
(mounting locations) is not changed but the logical configuration is changed for
management of the system boards.
1.2.1 Adding a System Board
You can use DR to add a system board to a domain provided that board is installed
in the system and not assigned to another domain. You can do so without stopping
the Solaris OS running in the domain.
A system board is added in such stages as connect, and configure.
In the add operation, the selected system board is connected to the target domain.
Then, the system board is configured to the Solaris OS of the domain. At this point,
addition of the system board is completed.
1.2.2 Deleting a System Board
You can use DR to delete a system board from a domain without stopping the Solaris
OS running in that domain.
A system board is deleted in such stages as unconfigure and disconnect. If the board
must be assigned to another domain, the delete operation must also include an
unassign step.
In the delete operation, the selected system board is unconfigured from its domain
by the Solaris OS. Then, the board is disconnected from the domain. At this point,
deletion of the system board is completed.
1.2.3 Moving a System Board
You can use DR to reassign a system board from one domain to another without
stopping the Solaris OS running in either domain.
This move function can change the configurations of both domains without physical
removal and remounting of the system board.
The move operation for a system board is a serial combination of the “delete” and
“add” operations. In other words, the selected system board is deleted from its
domain and then added to the target domain.
