Fujitsu M10/SPARC M10 Systems Product Notes for XCP Version 2240 ･ March 2015
162
Description
On a system to which Oracle VM Server
for SPARC 3.1.0.1 or later is applied, the
following event may occur: If all CPUs or
memory in an I/O domain are degraded
due to a CPU or memory failure, the
ldmd service abnormally terminates and,
as a result, the ldm(1M) command
terminates with an error.
If the domain configuration is restored in
the degraded configuration, both of the
following settings are reset to their
default values: the setting specifying
whether to enable/disable hypervisor
dump collection and the setting
specifying whether to enable/disable
automatic reboot during hypervisor
dump collection.
[Default values]
Hypervisor dump collection: Enabled
Automatic reboot during hypervisor
dump collection: Disabled
The ldmd(1M) daemon may repeat core
dump if a suspend process of the
appropriate domain fails during live
migration.
Workaround
This has been modified with SRU11.2.8
and Oracle VM Server for SPARC 3.2 for
Oracle Solaris 10.
[How to restore]
Replace the faulty CPU or memory.
If you want to boot Oracle Solaris while
leaving the faulty CPU or memory
installed, perform the following
procedure on the XSCF:
1. Execute the poweroff(8) command to
power off the physical partition (PPAR).
2. Execute the setdomainconfig(8)
command to place the PPAR in the
factory-default state.
XSCF> setdomainconfig -p ppar_id -c
default
3. Execute the poweron(8) command to
activate the PPAR.
Oracle Solaris reboots in a configuration
that includes only the control domain
(factorydefault).
This has been modified with SRU11.2.8
and Oracle VM Server for SPARC 3.2 for
Oracle Solaris 10.
[How to restore]
After executing the ldm(1M) command to
change the hypervisor dump setting,
save the domain configuration
information.
# ldm set-hvdump hvdump=XXXX
hvdump-reboot=YYYY
# ldm add-spconfig ZZZZ
After replacing the faulty component,
execute the setdomainconfig(8)
command to initiate a reboot with the
original domain configuration.
This has been modified with SRU11.2.8
and Oracle VM Server for SPARC 3.2 for
Oracle Solaris 10.
[How to restore]
Restart the physical partition according
to the following steps.
1. Execute the poweroff(8) command to
power off the physical partition (PPAR).
2. Execute the poweron(8) command to
restart PPAR.
