Lenovo Flex SystemChassis Management Module 2 command-line interface: env command

This command sets the persistent environment for commands that are entered during the remainder of the current session.

The persistent command environment is indicated by the command prompt. When you start the command-line interface, the persistent command environment is the Lenovo Flex System chassis, denoted as system by the command prompt. You can target a single command to an environment other than the one that is set as the default by adding a -T option to the command that includes a valid target destination (see Command targets for information). Target environments can be specified using the full path name, or using a partial path name based on the persistent command environment. Full path names always begin with system. The levels in a path name are divided by using a colon ( : ).

See Command targets for a list of Lenovo Flex System components, command targets, command target paths, and the command targeting hierarchy that is supported by the env command. Target names have been selected to maintain scripting compatibility with other Lenovo systems.

Note: To see installed targets for your Lenovo Flex System chassis, use the list command.

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 env command errors for a list of error messages that are specific to the env command.

Example: To set the persistent target of commands to the system-management processor on the compute node in node bay 5, while the Lenovo Flex System chassis is set as the default command target, at the system> prompt, type

env -T system:blade[5]:sp

The following example shows the information that is returned:

system> env -T system:blade[5]:sp
OK
system:blade[5]:sp>

To set the persistent target of commands to the system-management processor on the compute node in node bay 5, while the Lenovo Flex System chassis is set as the default command target, at the system> prompt, you can also type

env -T blade[5]:sp

The following example shows the information that is returned:

system> env -T blade[5]:sp
OK
system:blade[5]:sp>

To issue the reset command on the compute node in node bay 5, while the CMM is set as the default command target, at the system:mm[x]> prompt, type

reset -T system:blade[5]
