For Windows

Under Windows, you set the environment variable through My Computer >

Properties

1 Click the

Start button, right-click My Computer, and choose Properties.

2In the

Properties dialog box, click the Advanced tab.

3On the Advanced tab, click the Environment Variables button.

You can add a new variable by clicking

New, or edit an existing variable

by selecting TW_CLI_LOG in the list and clicking

Edit.

4 If this is the first time you are creating the environment variable, and you

want to disable command logging, add the variable TW_CLI_LOG and

specify the value as OFF. (Command logging is on by default.)

5 If the environment variable already exists, you can enable or disable it by

editing the value and changing it to ON or OFF, as desired.

6 Restart your system for the new environment variable setting to take

effect.

Return Code

While informative messages are written to standard output, error messages are

written to standard error. On success, 0 is returned. On failure, 1 is returned.

To view the return code for Linux, at the shell command prompt, type:

echo $?

The screen reports either a 0 or a 1, depending on whether the command is

successful.

For example, if you have a 3ware controller with an ID of 0, you can type the

following command:

tw_cli /c0 show

(c0 information shown here)

echo $?

Note: Setting the environment variable according to the preceding description is

not persistent across reboot, because the the shell terminates when you power

down the system, and defaults are reset on powerup. To set an environment

variable that persists, set a global variable in a login config file (such as .rc or

.cshrc) that sets the variable to the desired state when the system powers up. For

details, see the manpage for the shell you are using.
