Fujitsu M10/SPARC M10 Systems Product Notes for XCP Version 2240 ･ March 2015
172
Description
If a memory error occurs and all the
memories assigned to the guest domain
are degraded, ldmd(1M) causes a core
dump to abnormally terminate and the
ldm(1M) command ends with an error.
When you start the SunVTS 7.0 ps14 and
ps15 tests in a SPARC M10 system, they
may terminate with an error.
If a system board is added to the PPAR
by dynamic reconfiguration of physical
partitions after booting the Oracle Solaris
in the control domain with the
factory-default configuration, or if CPUs
on the system board are added to a
domain by the ldm add-vcpu command
after the system board is added by
dynamic reconfiguration of physical
partitions, the system will panic with the
following message:
panic[cpuX]/thread=XXXXXXXXXXX:
mpo_cpu_add: Cannot read MD
Workaround
This has been modified with SRU11.1.10.
5.0. On Oracle Solaris 10, it has been
modified with Oracle VM Server for
SPARC 3.1.
If this defect occurs because SRU is not
applied, replace the memory having an
error.
If you want to start Oracle Solaris while
the memory having an error remains to
be mounted, start it using the following
procedure from XSCF.
1. Execute the poweroff(8) command to
turn off the power of the physical
partitions (PPARs).
2. Execute the setdomainconfig(8)
command to restore PPARs to their
factory-default state.
XSCF> setdomainconfig -p ppar_id -c
default
3. Execute the poweron(8) command to
start the PPARs.
Oracle Solaris is started in the factory-
default configuration which consists of
only control domains.
This has been modified with Oracle
Solaris 11.1 SRU4.6, and the patch
149395-02 for Oracle Solaris 10.
There is no workaround other than
applying the modification.
This has been modified with SRU11.1.7.5
and Oracle Solaris 10 patch 150400-12.
Meanwhile, when this fix has been
applied to the system, if a system board
is added to the system by means of the
dynamic reconfiguration of physical
partitions, the following message may be
output but as it has no effect on the
system, ignore it.
WARNING: mpo_cpu_add: defaulting to
lgroup x for CPU x
For the control domain or the domain
whose CPU is added by the ldm
add-vcpu command, add the following
line to the domain's /etc/system file and
reboot the Oracle Solaris.
