8-8 SPARC Enterprise Mx000 Servers XSCF User’s Guide • December 2010
TABLE 8-1 describes the firmware update types and update times.
Note – (1) Corresponds to a Motherboard unit in the M4000/M5000 servers. (The same is
true for the description below.) Also, turn off the input power before replacing the
Motherboard unit.
TABLE 8-1 Firmware Update Types and Timing
Type Description Conditions Update Time
Operator's update
(XCP update)
Imports XCP and updates the
XSCF firmware and
OpenBoot PROM firmware on
the XSBs belonging to all
domains (including pooled
domains).
This is also referred to as
"XCP update."
The system power is off (input
power is on and all domains
are stopped), or power to the
domains is on.
Note: The update is completed
at the time of a reboot for
application in all domains.
XCP update time
Automatic update
(Automatic matching of
versions)
Note: In the M3000
server, automatic update
is not available.
• When a CPU/Memory
Board unit (Note 1) is
added or replaced, or the
XSCF Unit is replaced, the
firmware version of each
replacement component is
automatically matched to
the version of the replaced
component.
(Note 2)
However, when a component
is replaced in the state of input
power off (The cold
replacement), the firmware is
not updated automatically.
• When the DR function is
used to add, move, or
replace a system board
(XSB), the firmware
version is automatically
matched to the firmware
version in the domain that
uses the system board.
The system power is off (input
power is on and all domains
are stopped), or power to the
domains is on.
• In the system with
redundant XSCF Units, If
you replace an XSCF Unit
by using the maintenance
guidance, the firmware
version of the replacement
XSCF Unit is matched to
the firmware version of the
replaced XSCF Unit.
• In CPU/Memory Board unit
addition or replacement, the
target domain need not be
rebooted for application of
the OpenBoot PROM
firmware. However, when
the domain is powered off,
the number of versions is
matched by the startup of
the domain.
•Time of CPU/Memory
Board unit addition or
replacement. Or time of
replacement of an XSCF
Unit that is configured
redundantly
• Time of addition, move, or
replacement of a system
board by the DR function
