Omcong Chassis Leds Or Omcong Mainsystem Leds
Use the omcong chassis leds or omcong mainsystem leds command to specify when to ash a chassis fault LED or chassis
identication LED. This command also allows you to clear the LED of the system hard drive. The following table displays the valid
parameters for the command.
Table 50. Valid Parameters Of Omcong Chassis Leds Or Omcong Mainsystem Leds
name=value pair 1 name=value pair 2 Description
index=<n> NA Number of the chassis where the LED
resides (defaults to chassis 0, main system
chassis).
led=fault severity=warning | critical Select to ash the LED either when a
warning event occurs or when a critical
event occurs.
led=hdfault action=clear Sets the number of faults for the hard
drive back to zero (0).
led=identify ash=o | on time-out=<n> Sets the chassis identication LED to o
or on. Set the time-out value for the LED
to ash to a number of seconds.
Omcong Chassis Memorymode Or Omcong Mainsystem Memorymode
Use the omcong chassis memorymode or omcong mainsystem memorymode command to specify the redundancy mode to use
for the system memory in case of memory errors.
Redundant memory enables a system to switch to other available memory modules if unacceptable errors are detected in the
modules that the system is currently using. The omcong chassis memorymode or omcong mainsystem memorymode command
allows you to disable redundancy; when you disable redundancy, you instruct the system not to switch to other available memory
modules when the memory module the system is using begins to encounter errors. To enable redundancy, choose among spare,
mirror, raid, and DDDC.
Spare mode disables a bank of system memory in which a correctable memory event is detected, enables the spare bank, and copies
all the data from the original bank to the spare bank. Spare bank requires at least three banks of identical memory; the operating
system does not recognize the spare bank.
Mirror 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.
RAID mode provides an extra level of memory checking and error recovery at the expense of some memory capacity.
The DDDC mode enables double device data correction. This ensures data availability after hard failure of x4 DRAM.
NOTE: This command is applicable only on systems prior to PowerEdge 12G systems. On PowerEdge 12G systems,
memorymode is grouped under Memory Settings of the BIOS setup group. For more information, see BIOS Setup Groups
on PowerEdge 12G Systems.
To congure the attribute on systems prior to PowerEdge 12G, see the following table. The table displays the valid parameters for
the command.
Table 51. Valid Parameters Of
Omcong Chassis Memorymode Or Omcong 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 | dddc
spare: Disables the memory module that has a correctable
memory event and copies the failing module’s data to a spare
bank.
