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.
