Enhanced Support Facility 2.6 User's Guide

7.1.2 Software

The serial port driver in the FJSVse (for PRIMEPOWER 800/1000/2000 and GP7000F Models 1000/2000 with Solaris 7 OS or later), FJSVsef (for PRIMEPOWER 800/1000/2000 and GP7000F Models 1000/2000 with Solaris 2.6 OS), and FJSVsec (for PRIMEPOWER 900/1500/2500/HPC2500 with Solaris 8 OS or later) packages, included with Enhanced Support Facility (ESF), controls the onboard serial ports mounted on the system boards.

In addition to the functions of the se driver, included in Solaris OS, this serial port driver provides the following RAS (Reliability, Availability, and Serviceability) features:

• If a primary (main) serial port is broken while the system is booting, system uses a secondary (standby) serial port and disables the broken serial port.
• Furthermore, when OS is Solaris 8 OS or later, the function which dualities the communication path from an onboard serial port to a system console (console path) is supported. The contents of a function of the redundant console path are as follows.
• IOMP (I/O Multi Pathing) function is supported. It changes to a standby side automatically at the time of hardware failure detection of the serial port for consoles under OS operation, and operation of OS console is continued.
• DR (Dynamic Reconfiguration) function is supported. The system board with the broken serial port can be replaced while the system is running.
• By using with the system console software, the function to monitor the communicating state of the connected equipment from a RS-232C cable to the System Management Console, and to switch a console path automatically when unusual is supported.

The kind of monitoring function of the duplicated console path supported by the combination of ESF and SCS is as follows.
