Practical Examples of DR |
This chapter provides examples of DR operations, such as the addition, deletion, move, and replacement of system boards.
Each example shows an operation procedure using the command line interface of the XSCF shell. Similar procedures can also be applied to DR operations using the browser-based interface of the XSCF Web.
Note that the sections below explain only procedures such as those for checking the status of parts and devices for DR operations and not hardware operations (e.g., installing, removing, and replacing system boards). See the Service Manual for your server, as needed.
| Note - If your server is configured with SPARC64 VII processors, some restrictions regarding DR might apply. Please see SPARC64 VII+, SPARC64 VII, and SPARC64 VI Processors and CPU Operational Modes. |

FIGURE 4-5 Example: Adding a System Board
2. Check the status of the domain.
Execute the showdcl(8) command to display domain information, and then check the operation status of the domain. Based on the operation status of the domain, determine whether to perform the DR operation or change the domain configuration.
3. Check the status of the system board to be added.
Execute the showboards(8) command to display system board information, and then check the status of the system board to be added and confirm its registration in the DCL.
If you need to change the PSB configuration, use the setupfru(8) command. If the system board to be added is not registered in the DCL, register the system board in the DCL of the target domain by using the setdcl(8) command.
Execute the addboard(8) command to add the system board to the move-destination domain.
5. Check the status of the domain and added system board.
When the addboard(8) command ends normally, execute the showdcl(8) command to check the operation status of the domain, and then execute the showboards(8) command to check the status of the added system board.
If the addboard(8) command completes abnormally or leaves the board in an unwanted status, refer output messages to identify the problem, then correct it.
This section provides an example of operation to delete a system board from a domain. In the example, a procedure conforming to Flow: Deleting a System Board, is used, and the system board shown in the figure is deleted using the XSCF shell.
FIGURE 4-6 Example: Deleting a System Board
