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

Description
While a physical partition (PPAR) is
operating or when a PPAR is turned off,
master/standby XSCF switching may
occur.
If master/standby switching occurs, the
following message is displayed on the
console of the master XSCF.
Kernel panic - not syncing: MBC Dual
ifcut interrupt.
If data is transmitted via SSH by the
snapshot(8) -t command, this transmission
may be delayed by about 10 to 30
minutes in comparison with transfer
using USB devices and XSCF Web.
Suppose that multiple physical partitions
(PPARs) are simultaneously started by
the poweron -a command. The error
message "Error storing configuration
variable. LDC is not up Configuration
variable setting will not persist after a
reset or power cycle" may be output to
the OS console after the message "Unable
to connect to Domain Service providers."
Oracle Solaris may be started without
applying the OpenBoot PROM
environment variable specified with the
setpparparam(8) command.
Update of the PCI expansion unit
firmware may fail. If it fails, "LINKCARD
update is failed" appears in the event log.
[Example]
SCF:LINKCARD update is failed
(LINKCARD=1, bank=0, PCIBOX
version=1130: last version=1120)
In a configuration with 3 or more BBs, or
with crossbar boxes, when the XSCF
master/standby switchover is executed
due to some abnormality on the master
XSCF, the master XSCF may fail to switch
over to the standby XSCF and start up as
another master XSCF. Due to this, the
system seems to contain two master
XSCFs. Normal behavior of a system is
not guaranteed when there are two
master XSCFs in the system.
This state can be confirmed by a lighted
MASTER LED at the rear panel of two
chassis.
Workaround
There is no effective workaround.
As a result of this defect, master/standby
switching occurs, but this does not affect
the system, and the system can be
operated continuously.
There is no effective workaround.
Even if transfer is delayed, there is no
problem with the collected data.
There is no effective workaround.
Restart the control domain for the
physical partition (PPAR) for which the
error message was output.
There is no effective workaround.
Execute the ioxadm -c update command
to update the PCI expansion unit
firmware again.
There is no effective workaround.
[How to restore]
The system can be operated normally
when the number of master XSCFs
automatically returns to one after a few
minutes.
If the number of master XSCFs does not
return to one even after 15 minutes, press
the RESET switch at the rear panel of all
existing SPARC M10 systems and
crossbar boxes. The system can be
operated normally after that.
