96 omconfig: Managing Components Using the Instrumentation Service
Mirroring mode switches to a redundant copy of memory when an uncorrectable memory event is
detected. After switching to the mirrored memory, the system does not switch back to the original system
memory until the next reboot. The operating system does not recognize half of the installed system
memory in this mode.
Table 6-10 shows the valid parameters for the command.
omconfig chassis temps
Use the omconfig chassis temps command to set warning thresholds for temperature probes. As with
other components, you can view both warning and failure threshold values, but you cannot set failure
thresholds. Your system's manufacturer sets the minimum and maximum failure thresholds.
NOTE: Settable thresholds vary from one system configuration to another.
Valid Parameters for Temperature Warning Thresholds
Table 6-11 shows the valid parameters for setting temperature warning thresholds:
Table 6-10. omconfig chassis 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 |
mirrored | 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.
Mirrored switches the systems to a mirrored copy of the memory if the
failing module has an uncorrectable memory event. In mirrored mode,
the operating system does not switch back to the original module until
the system reboots.
RAID5 is a method of system memory configuration. This is logically
similar to the RAID5 mode used in hard drive storage systems. This
memory mode gives you 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.
Table 6-11. omconfig chassis temps
name=value pair Description
index=<n> Number of the probe or probe index (must be specified).
warnthresh=default Sets minimum and maximum warning thresholds to default.
minwarnthresh=<n> Minimum warning threshold (1 decimal place).
maxwarnthresh=<n> Maximum warning threshold (1 decimal place).
