1.2.4 Replacing 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 re-
installed 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.
1.3 Security
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.
1.4 Overview 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.
