Megarac provides a simple CLI to manage BMC operations. You can specify BMC details directly or use a profile configured with the required details.
megarac [global options] command [command options] [arguments...]
--help, -h: Show help.
Configure the profile with the BMC authentication details.
Profiles are stored in the user's home directory in the .megarac/profiles directory.
Add/update profile:
megarac configure add --name [profile_name] --host [hostname] --user [username] --password [password] [--insecure] [--use-ssl false]
List profiles:
megarac configure list
Remove profile:
megarac configure remove --name [profile_name]
Control the power state of the server.
Power on:
megarac power on [--profile profile_name] or megarac power on --host [hostname] --user [username] --password [password] [--insecure] [--use-ssl false]
Power off:
megarac power off [--profile profile_name] or megarac power off --host [hostname] --user [username] --password [password] [--insecure] [--use-ssl false]
Power status:
megarac power status [--profile profile_name] or megarac power status --host [hostname] --user [username] --password [password] [--insecure] [--use-ssl false]
Example:
> go run . power --profile endor status
Power status for endor-bmc.lan: on
Get sensor readings from the BMC.
List sensors:
megarac sensors list [--profile profile_name] [-all] [--find name] or megarac sensors list --host [hostname] --user [username] --password [password] [--insecure] [--use-ssl false] [-all] [--find name]
Example:
> go run . sensors --profile endor list --all
