Windows Special Administration Console (SAC)

After an nPartition has successfully loaded Microsoft® Windows® Server 2003, you can access a text-based Windows administration interface at the nPartition console.

The Special Administration Console (SAC) interface lets you interact with the Windows operating system running on an nPartition by using the SAC> command prompt that is provided at the nPartition console interface. The SAC commands listed in Table 4-1 are provided for managing Windows.

The SAC interface enables you to have administrative access to Windows on an nPartition even if Windows networking is not functional.

Tips for using the SAC interface and a table of SAC commands follow.

SAC Interface: Tips for Interacting with Windows Special Administration Console. When using the Windows SAC interface through an nPartition console, you can use the commands in Table 4-1. You also can use the following tips to help complete tasks with the SAC.

To list all commands available from the SAC, issue the ? or help command at the SAC> prompt.
To list basic identification and boot information about the instance of Windows running on the nPartition whose console you are using, issue the id command.

To switch among the "channels" provided by the SAC interface, use the channel management command.

SAC Channel Management Commands.

Esc Tab — Change channels: if multiple channels exist, typing Esc Tab switches to the next channel and typing Space selects a channel.

ch — List all channels.

ch -? — Display the channel-management command help.

ch -si # — Switch to a channel by its number.

ch -sn name — Switch to a channel by its name.

ch -ci # — Close a channel by its number.

To create a new Windows command prompt that you can interact with through the nPartition console, issue the cmd command.
The cmd SAC command creates a new channel for the command prompt, which you can then switch to (using Esc Tab, or other commands) in order to login to Windows running on the nPartition.
When you need to type function keys and are using the SAC, type the following key sequence: Esc #
For example, for the F3 key type Esc then 3 in quick sequence.

Table 4-1 lists the commands you can issue at the Windows SAC> prompt, which is provided through an nPartition console after Windows has booted.
