E.2.2.1 Selecting a New System Master
If the system master is replaced in the field by a new system board, the
OpenBoot PROM on the replacement board will not have the specific system
information that is necessary for an OBP master.
System Boards with PROM Revision 2.11 (or Lower)
PROM revision 2.11 (or lower) uses master-nvram scheme to select the system
master board. In multiple-board configurations, when the system is powered
on for the first time, OBP may prompt you to select a system board to become
the new master. This prompt will appear only if:
•
The system does not recognize any board as the system master.
•
More than one board is recognized as being qualified to function as the
system master.
Caution – The system master board must be connected to a terminal or you
!
will not see the OBP message prompt. If the terminal is connected to the wrong
board, the message will not appear. The system may seem to be locked up, but
OBP is only pausing, waiting for you to respond to the prompt.
The following example for a three board system shows the prompt and the
recommended responses (0 and y).
