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

Description
Even when rotation abnormality is found
on both fans at the same time in the same
fan unit, error log for only one fan is
registered and thus the system is not
shutdown. As a result, temperature of
components like CPU may rise.
In a system with three or more BBs or
with cross boxes, if the master/standby
switchover if executed for more than 256
times, the "SCF process down detected"
error is detected on the slave XSCF and
XSCF "coremgrd" may cause process
down.
If cold replacement of CPU memory unit
lower (CMUL) or a motherboard unit
(MBU) is done in the following
procedure, the physical partitions
(PPAR) may not start.
1. Execute the "restoredefaults -c factory"
command.
2. After XSCF has stopped, turn off the
input power of the system (AC OFF).
3. Replace the CMUL or MBU without
replacing the microSD card.
4. Turn on the input power of the system.
Workaround
After the collection is complete, turn
off/on the input power (AC OFF/ON) of
all the chassis and then contact the
maintenance staff.
There is no effective workaround.
[How to Restore]
If the system is not shut down when fan
rotation abnormality is detected, if any of
the following symptom is confirmed in
the two fans which comprises the faulty
fan unit, change the following fan unit as
soon as possible:
- The "showenvironment fan" command
shows that the number of rotation has
been decreased.
- Visual judgment reveals that the
number of rotation has been stopped.
Do not perform consecutive XSCF
master/standby switchover.
[How to Restore]
Reset the XSCF.
The system will become usable.
Replace CMUL or MBU in the following
procedure.
1. Execute the "restoredefaults -c factory"
command.
2. To stop XSCF as in procedure 1, turn
off/on the input power of the system
(AC OFF/ON) and then confirm that
XSCF has started.
3. Replace the targeted CMUL or MBU.
[How to Restore]
Restore with the following procedure:
1. Turn off the input power of the system
(AC OFF).
2. Temporarily mount the microSD card
that was mounted on the CMUL or
MBU, when the "restoredefaults -c
factory" command was executed, to the
new unit.
3. Confirm that XSCF has started after
turning on the input power (AC ON).
4. Turn off the input power of the system
(AC OFF).
5. Extract the microSD card that was
temporarily mounted and mount the
