CLI Guide

For some chassis, you can assign a different name. You cannot rename the main system chassis. In the following example, the command
renames chassis 2 from storscsi1 to storscsia:
omconfig chassis info index=2 name=storscsia
or
omconfig mainsystem info index=2 name=storscsia
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 Or Omconfig Mainsystem Leds
Use the omconfig chassis leds or omconfig mainsystem leds command to specify when to flash a chassis fault LED or
chassis identification 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 51. Valid Parameters Of Omconfig Chassis Leds Or Omconfig 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 flash 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 flash=off | on time-out=<n> 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 Or Omconfig Mainsystem
Memorymode
Use the omconfig chassis memorymode or omconfig 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 omconfig chassis memorymode or omconfig 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.
