Fujitsu M10/SPARC M10 Systems Product Notes for XCP Version 2240 ･ March 2015

Description
If you power off the input power supply
while the status of the physical partition
(PPAR) is PowerOn (from the startup of
Oracle Solaris to the completion of
PowerOff), an SRAM serious error occurs
in any of the SPARC M10-4S units in the
PPAR when you next power on the input
power supply, preventing you from
powering on the input power supply.
The power may not be turned on/off
from the operation panel.
Executing the poweron -a command
leads to the failure of power-on if more
than one PPAR is powered on or more
than one PPAR has failed in the system
that has multiple physical partitions
(PPARs).
Workaround
When you power off the input power
supply, do so after disconnecting the
PPAR power supply in advance and
making sure that disconnection is
complete.
[How to restore]
If any problem occurs, restore the
configuration with the following
procedure:
1. Save settings with the dumpconfig(8)
command.
2. Initialize the system to the factory
default with the restoredefaults -c
factory command.
3. Confirm that the READY LED of XSCF
or XSCF unit is lighted up after
performing AC OFF/ON.
4. Replace the CPU memory unit lower
(CMUL) or the motherboard unit
(MBU).
5. Restore the configuration with the
restoreconfig(8) command.
If you power on from the XSCF shell,
execute the poweron(8) command. If you
power off from the XSCF shell, execute
the poweroff(8) command.
[How to restore]
If this event occurs, power off the
physical partition (PPAR) by using the
poweroff -f command.
Specify the -p option to execute the
poweron(8) command and turn on the
power of each PPAR.
[How to restore]
If this event occurs, execute the poweroff
-f command to forcefully power off the
PPAR whose power has stopped being
supplied during the middle of the power
supply process. Then execute the
poweron -p command to power on the
PPAR.
