XD - Diagnostics or Reset of MP. Use this command to perform some simple checks to confirm the health and connectivity status of the MP. The following tests are available: • MP Parameter Checksum • Verify I2C connection (get BMC Device ID) • LAN connectivity test using ping • Modem self-tests Also, you can reset the MP safely using this command, without affecting the operation of the server. Special Administration Console Special Administration Console (SAC) is the primary Emergency Management Services command-line environment hosted by Windows Server 2003. It is separate from the command-line environment and provides different functionality. SAC runs on top of the EMS. The SAC prompt provides a basic set of commands to manage the setup, installation, and repair of the OS. Use these commands to examine logs, shut down or reboot, kill processes, or change process priority, and set network parameters. Access the SAC prompt through the Integrity iLo console menu. The connection for the SAC is directly into the kernel and is not dependent on the health of any user code or of any device driver. This means that you have more tools available to repair an unhealthy system that might be unresponsive from the GUI. This direct-to-kernel path is similar to the kernel debugger and is always available. From the SAC prompt, you can create and use a standard Windows command line. During setup, the SAC also automatically starts three setup channels so you can monitor installation progress. A subset of commands is available for use when the system is in distress. This is known as the !SAC prompt. This change from SAC to !SAC mode is automatic. The SAC and !SAC prompts are primarily used for setup or to bring a distressed system back to health so that you can use in-band tools such as Remote Desktop. Because SAC is available early in the boot process, you can use it to manage the server during normal system operation and initiation. You can also use it when the system is in safe mode and during GUI-mode setup. When Emergency Management Services is enabled, SAC remains active as long as the kernel is running. Access SAC through the MP. When a server is running normally, you can connect to it over the network and administer it using such tools as Windows Management Instrumentation (WMI), Terminal Services Remote Desktop for Administration, Microsoft Management Console (MMC), Telnet, Microsoft Script Host, and other third-party tools: • WMI: A management infrastructure in Windows that supports monitoring and controlling system resources through a common set of interfaces. WMI provides a logically organized, consistent model of Windows operation, configuration, and status. • Terminal Services: The underlying technology that enables Remote Desktop, Remote Assistance, and Terminal Server. • MMC: A framework for hosting administrative tools called snap-ins. A console can contain tools, folders or other containers, World Wide Web pages, and other administrative items. • Telnet: A protocol that enables Internet users to log in to and enter commands on a headless computer linked to the Internet, as if you were using a text-based terminal directly attached to that computer. Telnet is part of the TCP/IP suite of protocols. The term telnet also refers to the software (client or server component) that implements this protocol. When a server is not functioning normally, you need to access the server without relying on the network. You must establish a secure connection through a phone line or serial port, or through an additional network connection (possibly on a secondary network). For servers equipped with the proper firmware, Emergency Management Services provides functionality that you can use to administer a server using a headless console. Except for hardware maintenance and replacement, all administrative functions that you can accomplish using the 94 Management processor and Special Administration Console

Special Administration Console
Special Administration Console (SAC) is the primary Emergency Management Services
command-line environment hosted by Windows Server 2003. It is separate from the command-line
environment and provides different functionality.
SAC runs on top of the EMS. The SAC prompt provides a basic set of commands to manage the
setup, installation, and repair of the OS. Use these commands to examine logs, shut down or
reboot, kill processes, or change process priority, and set network parameters. Access the SAC
prompt through the Integrity iLo console menu.
The connection for the SAC is directly into the kernel and is not dependent on the health of any
user code or of any device driver. This means that you have more tools available to repair an
unhealthy system that might be unresponsive from the GUI. This direct-to-kernel path is similar
to the kernel debugger and is always available.
From the SAC prompt, you can create and use a standard Windows command line. During setup,
the SAC also automatically starts three setup channels so you can monitor installation progress.
A subset of commands is available for use when the system is in distress. This is known as the
!SAC prompt. This change from SAC to !SAC mode is automatic.
The SAC and !SAC prompts are primarily used for setup or to bring a distressed system back to
health so that you can use in-band tools such as Remote Desktop.
Because SAC is available early in the boot process, you can use it to manage the server during
normal system operation and initiation. You can also use it when the system is in safe mode and
during GUI-mode setup. When Emergency Management Services is enabled, SAC remains active
as long as the kernel is running. Access SAC through the MP.
When a server is running normally, you can connect to it over the network and administer it
using such tools as Windows Management Instrumentation (WMI), Terminal Services Remote
Desktop for Administration, Microsoft Management Console (MMC), Telnet, Microsoft Script
Host, and other third-party tools:
•

system resources through a common set of interfaces. WMI provides a logically organized,
consistent model of Windows operation, configuration, and status.
