3ware Serial ATA RAID Controller CLI Guide
Using a single command with output
You can use 3ware CLI with line arguments, processing a single command at
a time. To do so, simply enter the command and the arguments.
Single commands can be useful when you want to perform a task such as
redirecting the output of the command to a file. It also allows you to use the
command line history to eliminate some typing.
Syntax
tw_cli
<command_line_arguments>
Example
tw_cli /c0 show diag > /tmp/3w_diag.out
Using an input file to execute a script
You can operate 3ware CLI scripts by executing a file. The file is a text file
containing a list of CLI commands which you have entered in advance. Each
command must be on a separate line.
Syntax
tw_cli -f <filename>
Where
<filename>
is the name of the text file you want to execute.
Example
tw_cli -f clicommand.txt
This example executes the file
clicommand.txt
, and runs the CLI commands
included in that file.
Scripting examples
Following is a scripting example for a 4-port controller using a text file called
config_unit.txt, containing three commands. This example sets up a 4-port
controller with two units, each with 2 drives mirrored. It then prints the
configurations for verification. The commands included in the script file are:
/c0 add type=raid1 disk=0-1
/c0 add type=raid1 disk=2-3
/c0 show
Following is a scripting example for a 12-port controller using a text file
called config_unit.txt, containing three commands. This example sets up a 12-
port controller with two units: one with the first 2 drives mirrored, and another
