Use this topic to find information about the Virtual I/O Server command-line interface.
The Virtual I/O Server is configured and managed through a command-line interface. In environments where no HMC is present, some Virtual I/O Server tasks can also be performed using the Integrated Virtualization Manager. All aspects of Virtual I/O Server administration can be accomplished through the command-line interface, including the following:
In addition, in Integrated Virtualization Manager manager environments, the Virtual I/O Server command-line interface is used for partition management.
The first time you log in to the Virtual I/O Server, use the padmin user ID, which is the prime administrator user ID. You will be prompted for a new password.
Upon logging in, you will be placed into a restricted Korn shell. The restricted Korn shell works in the same way as a standard Korn shell, except that you cannot do the following:
As a result of these restrictions, you will not be able to execute commands that are not accessible to your PATH variables. In addition, these restrictions prevent you from sending command output directly to a file. Instead, command output can be piped to the tee command.
After you log in, you can type help to get information about the supported commands. For example, to get help on the errlog command, type help errlog.
The Virtual I/O Server command-line interface functions similarly to a standard command-line interface. Commands are issued with appropriate accompanying flags and parameters. For example, to list all adapters, type the following:
lsdev -type adapter
In addition, scripts can be run within the Virtual I/O Server command-line interface environment.
| Command | Function |
|---|---|
| awk | Matches patterns and performs actions on them. |
| cat | Concatenates or displays files. |
| chmod | Changes file modes. |
| cp | Copies files. |
| date | Displays the date and time. |
| grep | Searches a file for a pattern. |
| ls | Displays the contents of a directory |
| mkdir | Makes a directory. |
| man | Displays manual entries for the Virtual I/O Server commands. |
| more | Displays the contents of files one screen at a time. |
| rm | Removes files. |
| sed | Provides a stream editor. |
| stty | Sets, resets, and reports workstation operating parameters. |
| tee | Displays the output of a program and copies it to a file. |
| vi | Edits files with full screen display. |
| wc | Counts the number of lines, words, and bytes or characters in a file |
| who | Identifies the users currently logged in. |
As each command is executed, the user log and the global command log are updated.
The user log will contain a list of each Virtual I/O Server command, including arguments, that a user has executed. One user log for each user in the system is created. This log is located in the user's home directory and can be viewed by using either the cat or the vi commands.
