110 omconfig: Managing Components
Table 4-8 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 4-8. 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.
raid5: 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 provide optimized 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.
