alarm command

This command acknowledges or unacknowledges alarms, clears alarms, or creates custom alarms for the specified command target.

Note:
  • The alarm command applies only to CMMs installed in a Lenovo Flex System Carrier-Grade chassis.
  • All alarm commands are processed at the chassis (system target) level. Specifying a command target (-T target_name) is optional: alarm commands issued to any command target will be accepted and processed.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or alarm command errors for a list of error messages that are specific to the alarm command.

Create alarm Creates an alarm request for the specified target, including an alarm severity level and description. alarm -create -s level -p " desc"

where

  • level is the severity level:
    • CRT (critical)
    • MJR (major)
    • MNR (minor)
  • desc is a quote-delimited description of the alarm up to 63 characters in length.
This command can only be run by users who have one or more of the following command authorities:
  • Supervisor
  • Chassis configuration (for CMM, power supply, or fan module)

Example: To acknowledge a power alarm with an ID of 00000450 for the power supply in bay 2, while the Lenovo Flex System Enterprise Chassis is set as the persistent command environment, at the system> prompt, type 
alarm -ack -i 00000450

The following example shows the information that is returned from this command.

system> alarm -ack -i 00000450
OK
