Dell Command Line Interface manual Omconfig chassis leds, Omconfig chassis memorymode

As with other commands, the CLI issues an error message if you do not have a chassis 2 (the main chassis=0). The CLI allows you to issue commands only for the system configuration you have.

omconfig chassis leds

Use the omconfig chassis leds command to specify when to flash a chassis fault LED or chassis identification LED and allow you to clear the LED for the system's hard drive. Table 4-10 shows the valid parameters for the command.

Table 4-10. omconfig chassis 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 flash the LED either when a warning event occurs or
		when a critical event occurs.

led=hdfault	action=clear
led=identify	flash=off on
	time-out=<n>

Sets the number of faults for the hard drive back to zero (0).

Sets the chassis identification LED to off or on. Set the time-out value for the LED to flash to a number of seconds.

omconfig chassis memorymode

Use the omconfig chassis memorymode command to specify the redundancy mode you want to use for your system’s 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 it is currently using. The omconfig chassis 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 module the system is using begins to encounter errors. If you want to enable redundancy, you must choose among spare, mirror, and RAID.

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.

Table 4-11 shows the valid parameters for the command.
