Enhanced Support Facility 2.6 User's Guide

1.1.2 Software

SCF driver controls the hardware SCF, and provides the following RAS (Reliability, Availability, and Serviceability) features vital for server system operation:

• Automatically shuts down the system to prevent damage when fan failures, abnormal temperatures, or other potentially destructive malfunctions occur.
• When redundant power supplies and fan units are possible for system, the failure of the power supply and the fan is notified to the operator, and maintains system operation.
  But the system will shut down to protect itself if all of the redundant components fail.
• When the degeneracy due to a partial system failure is done by the initial diagnosis of hardware at the system startup, the breakdown parts can be displayed by the command.
• Displays system configuration information on command.
• Controls system shutdown and power cutoff via the POWER switch.
• Allows installation of redundant power supplies and fans, and on hot-swappable systems, makes it possible to replace either of those devices while the system is operating.
• Allows the hot-swapping of internal disks during system operation.
• When an external power supply device is connected, allows the control of the operator call signal on user terminal board interfaces.
• For the Dynamic Reconfiguration Features (abbreviated here after as DR) of GP7000F model 1000/2000 and PRIMEPOWER 800/900/1000/1500/2000/2500, SCF driver offers DR Connection Script.
