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

Description
If you turn on the input power supply to
a SPARC M10-4S chassis while a physical
partition (PPAR) is being powered on in
a system that has multiple PPARs, the
SPARC M10-4S chassis for which the
input power supply is turned on may not
be recognized by the master XSCF.
If you collect a snapshot by specifying
the -a option, "XSCF Kernel Panic" may
occur due to the increased load on the
master XSCF.
If XSCF panic occurs in a SPARC M10-4S
while processing the diagnose by the
POST after a physical partition (PPAR) is
powered on in the system that has more
than one SPARC M10-4S chassis, then the
power may be disconnected without
continuing the process of powering on
the PPAR.
If each physical partition (PPAR) is
configured with one system board (PSB)
in the system that has more than one
SPARC M10-4S chassis and crossbar box,
the power of the crossbar unit of a
crossbar box is not stopped and the
crossbar box is also powered on.
Hypervisor Abort or OS PANIC may
occur if all the PPARs are powered on
using the poweron -a command in a
system that has four or more SPARC
M10-4S chassis units with multiple
physical partitions (PPARs).
Immediately after starting the XSCF, the
system board (PSB) may be recognized as
"Unmount" and the addboard(8)
command or the poweron(8) command
may fail.
Workaround
Power on the input power supply to all
the crossbar boxes and SPARC M10-4S
chassis that compose the system before
powering on a PPAR.
If you collect a snapshot of the entire
system, collect snapshots one by one by
specifying a BB-ID of SPARC M10-4S
using -b option and not -a option.
Perform this operation on all SPARC
M10-4S.
There is no effective workaround.
Make sure that the XSCF of each SPARC
M10-4S is restarted. Power on the PPAR
again if they are restarted.
There is no effective workaround.
Do not power on all the PPARs at the
same time using the poweron -a
command. Power on each PPAR using
the -p option.
Wait for about 30 seconds after starting
up the XSCF and check that the target
PSB is mounted using the showboards(8)
command. Then execute the addboard(8)
or poweron(8) command.
