If Oracle Solaris is activated during memory degradation, a
panic may occur (CR:15851441)
[Workaround]
If a panic occurs due to a memory failure, replace the failed memory.
If a panic occurs due to the memory mirror mode setting, start the system from the
XSCF by using the following procedure.
Also, if a panic occurs due to a memory failure, starting the system from the XSCF by
using the procedure shown below may prevent the problem, but this method is not
always reliable. If a panic recurs even after the system is started by using the
following procedure, replace the failed memory.
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 is started in the factory-default configuration which consists of only
control domains.
If you set the mirror mode for the memory, configure a logical domain after setting
the mirror mode in the factory-default condition. Then, save the settings with ldm
add-spconfig.
In addition, you must not specify with ldm set-config or the setdomainconfig(8)
command of XSCF the settings that were saved with no mirror mode set, to the
environment where the mirror mode is used.
