Serial over LAN

Introduction

 

 

1.2.2Serial over LAN

Serial over LAN (SOL) is an IPMI v.2.0 defined capability that allows to establish a virtual serial console connection with the payload over LAN. The serial data of the payload is transferred to the IPMC. The IPMC generates RMCP+ packets, which are routed to the ethernet controller of the base interfaces. Be aware that SOL/LAN configuration is only possible if the Ethernet controller and its payload is fully powered, otherwise the completion code 0xD5 is returned. For more information on how to use and configure SOL see Chapter 4, SOL Module Configuration, on page 53.

1.2.3Sensors

Apart from several voltage and temperature specific sensors (for details refer to Sensor Data Records on page 29), the IPMC provides the following additional sensors:

Firmware Progress, and Boot

The IPMC firmware provides Firmware Progress (Table 3-24 on page

Error Sensor

43), and Boot Error (Table 3-16 on page 37) sensors to enable

 

payload firmware and payload OS to report boot progress and OS

 

Boot via IPMI event messages.

 

 

1.2.4MAC Address Record

The ATCA-7350 implements an MAC address FRU OEM record. You can retrieve all MAC addresses of the blade from the FRU information. For more details refer to MAC Address Record on page 27.

1.2.5Asynchronous Event Notification

To enable payload applications to be informed about graceful shutdown/reboot requests, the FRU Activate (Deactivate) and FRU Control (Graceful Reboot) command message is routed as a LUN2 message to the payload interface.

If the payload application has registered to these commands via the OpenIPMI library, it gets informed and can take all necessary actions before the payload is gracefully rebooted or shut- down.

1.2.6Graceful Shutdown Timeout

The IPMI command Set System Boot Options together with the parameter #98 can be used to persistently specify the timeout for Graceful Shutdown. For more information refer to Chassis Device Commands on page 18.
