94 omconfig: Managing Components Using the Instrumentation Service
Table 4-9 shows the valid parameters for the command.
omconfig chassis pwrmanagement/omconfig mainsystem
pwrmanagement
Use the omconfig chassis pwrmanagement or omconfig mainsystem
pwrmanagement command to configure power cap and manage profiles that
control power utilization.
Table 4-9. omconfig chassis memorymode/omconfig mainsystem memorymode
name=value pair 1 Description
index=<n> Number of the chassis where the memory module resides (the default is
chassis 0, the main system chassis).
redundancy=spare |
mirror | disabled |
raid5
Spare disables the memory module that has a correctable memory event
and copies the failing module’s data to a spare bank.
Disabled indicates that the system is not to use other available memory
modules if uncorrectable memory events are detected.
Mirror switches the systems to a mirrored copy of the memory if the
failing module has an uncorrectable memory event. In the mirror mode,
the operating system does not switch back to the original module until
the system reboots.
RAID-5 is a method of system memory configuration. This is logically
similar to the RAID-5 mode used in hard drive storage systems. This
memory mode provides an extra level of memory checking and error
recovery at the expense of some memory capacity. The RAID mode
supported is RAID level 5 striping with rotational parity.
opmode=mirror |
optimizer | advecc
Mirror switches the systems to a mirrored copy of the memory if the
failing module has an uncorrectable memory event. In the mirror mode,
the operating system does not switch back to the original module until
the system reboots.
Optimizer enables the DRAM controllers to operate independently in
64-bit mode and optimizes memory performance.
Advanced ECC (advecc) enables the two DRAM controllers to combine
in 128-bit mode and provide optimized reliability. Memory that cannot
be teamed by the controllers is not reported to the operating system.

config=budget cap=<value> Sets the threshold value for power budget.
setting=enable | disable enable: Enables powercap settings.
disable: Disables powercap settings.
