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

Description
failures may not be detected, and the
physical partition (PPAR) may hang up.
For a DDC failure, confirm whether any
of the following error logs is registered.
Msg: Critical low voltage error
Or
Msg: Critical high voltage error
Or
Msg: Power subsystem failure
For a SPARC M10-4S chassis with the
XSCF stopped, or with the input power
off (AC OFF), even if you execute the
initbb -f command to forcibly disconnect
the chassis from the system, the chassis
remains assigned to the physical
partition (PPAR).
To check this phenomenon, execute the
showboards(8) command to confirm
whether Assignment of the target SPARC
M10-4S chassis (PSB) remains "Assigned".

If the poweroff(8) command is executed
and the master chassis XSCF is reset
during the time that it takes for a prompt
to be returned, the following power
on/power off operation cannot be
executed.
An error may be detected in the Realtime
Clock (RTC) built into the SPARC M10
system and XSCF may not start.
If you disconnect and then connect the
USB memory while the executed
snapshot(8) command is collecting
information into the memory, the
hardware error below may be detected.
Workaround
There is no effective workaround.
[How to restore]
Perform the following on the disconnected
SPARC M10-4S chassis.
1. Execute the replacefru(8) command to
replace the chassis.
2. Power on (AC ON) the replacement
chassis.
- If the READY LED of the XSCF or
XSCF unit is lit
a. Complete replacefru(8) command
execution by following the
maintenance menu.
b. Execute the initbb(8) command to
disconnect the chassis from the
system.
y y - If the READY LED of the XSCF or
XSCF unit is not lit
n n Remove the chassis and replace the
XSCF unit or CPU memory unit
lower (CMUL) where a failure is
suspected.
There is no effective workaround.
If this phenomenon occurs, turn off the
input power to all chassis and then turn
it on again.
There is no effective workaround.
[How to restore]
Turn off the input power to the system
and then turn it on again (AC OFF/ON).
Do not connect and then disconnect the
USB memory while information is being
collected into the memory by the
snapshot(8) command.
