Description
If the following applies, "I/O devices
error detected" is detected at the time of
PPAR power-on and control domain
reboot: In SPARC M10-4/M10- 4S, the
CPU memory unit upper (CMUU) is
added to a configuration that has been
operated with only the CPU memory
unit lower (CMUL) and false has been set
as the IOreconfigure setting of the
physical partition (PPAR).
If XSCF switching is performed using the
switchscf(8) command, in rare cases, the
standby XSCF may not start.
Before active replacement of the XSCF
unit of the crossbar box is completed, the
replacefru(8) command is completed
normally.
When you replace the XSCF unit of the
crossbar box by using the replacefru(8)
command, the command is completed
normally, but the following error log
may be registered. The suspected
location indicated by this error log is
incorrect.
SCF:Board control error (link failed)
In case of a system comprising of several
SPARC M10-4S, if input power is turned
off and on (AC OFF/ON) on a number of
SPARC M10-4S chassis, while some other
slave chassis are running, the physical
partitions may not start.
Workaround
There is no workaround for errors that
are detected at power-on after the
addition.
Making the following setting prevents
the error detection that occurs every time
the PPAR is powered on or the control
domain is rebooted.
1. After starting Oracle Solaris, execute
the ldm rm-io command to delete the
PCIe root complex of the added
CMUU from the configuration of the
control domain.
2. Execute the ldm add-spconfig
command to save the constructed
logical domain configuration to the
XSCF.
There is no effective workaround.
[How to restore]
Turn off and then turn on the input
power supply (AC OFF/ON) to every
SPARC M10-4S or execute the
replacefru(8) command to perform
pseudo replacement (replacement work
without replacing any parts) of the
SPARC M10-4S that does not start.
When you use the replacefru(8)
command to replace the XSCF unit, the
following message may appear after you
replace the XSCF unit. If it does, wait for
10 minutes, and then enter "f".
The replacement of XBBOX#xx/XSCFU
has completed normally.[f:finish] :
Replace the XSCF unit of the same
crossbar box by using the replacefru(8)
command again. If you have turned off
the input power (AC OFF) during the
replacement work, disconnect and then
connect all the XSCF BB control cables.
When performing AC OFF/ON, do so on
all the chassis comprising a system.
[How to Restore]
Turn off input power of all the chassis
comprising the system and then turn on
the input power.
