1.2.4Replacing a System Board

You can use DR to remove a system board from a domain and either add it back later, or replace it with another system board, provided both boards satisfy DR requirements as described in this document. You can do so without stopping the Solaris OS running in either domain.

You can replace system board in the case of exchanging hardware resources such as CPUs, memory, I/O devices.

A system board is replaced successively in stages.

In the replace operation, the selected system board is deleted from the OS of the domain. Then, the system board is removed when it is ready to be released from its domain. After field parts replacement or other such task, the system board is reinstalled and added.

Note – You cannot use DR to replace a system board in a midrange server because doing so would replace an MBU. To replace a system board in a midrange server, you must turn off the power of all domains, then replace the board without using DR commands.

1.3Security

DR operations are executed based on privileges. For information about privileges and user accounts, see the SPARC Enterprise M4000/M5000/M8000/M9000 Servers Administration Guide.

1.4Overview of DR User Interfaces

DR operations are performed through the command line interface (CLI) within the XSCF shell or through the browser-based user interface (BUI) in the XSCF Web provided by the eXtended System Control Facility (XSCF). These operations are collectively managed by the XSCF. Furthermore, XSCF security management restricts DR operations to administrators who have the proper access privileges.
