Correction to Displaying POST Results

The command for displaying POST results in the Sun Fire 880 Server Service Manual is incorrect. To display the results of POST testing, type show-post-resultsat the ok prompt. The following is an abbreviated eaxmple of the command and output.

ok show-post-results

CPU0/Memory: OK

CPU1/Memory: OK

Correction to the diag-triggerSetting for Enabling ASR

The diag-triggerinformation in “How to Enable ASR” in the Sun Fire 880 Server Owner’s Guide is misleading. Step 2 recommends setting the diag-triggervariable to power-reset, error-reset, or soft-reset. However, setting the variable to power-resetrequires the user to power cycle the system in order for the system to deconfigure the failed hardware component.

Since the purpose of ASR is to provide for an automatic system recovery from certain types of hardware failures, setting diag-triggervariable to power-resetdoes not allow for an automatic recovery from a hardware failure. To enable ASR for an automatic recovery from a hardware failure, set the diag-triggervariable to error-resetor soft-resetas shown in the following example.

#ok setenv diag-trigger soft-reset

Note The ASR feature is not activated until you enable it at the system ok prompt. For more information about ASR, see the Sun Fire 880 Server Owner’s Guide.

Correct Usage of the ifconfig Command for PCI Hot-Plug

The procedure for hot-plugging a PCI card on a Sun Fire 880 Server running the Solaris 8 07/01 or 10/01 operating environment in the Sun Fire 880 Dynamic Reconfiguration User’s Guide does not fully explain the syntax for the ifconfig command. To prepare a PCI card for removal using the ifconfig command, you must first use the down option and then the unplumb option. To prepare a PCI card for installation using the ifconfig command, you must first use the plumb option and then the up option. The ifconfig syntax for removing a PCI card is as follows.

#ifconfig hme2:1 down

#ifconfig hme2:1 unplumb

The ifconfig syntax for installing a PCI card is as follows.

880 specifications

The Sun Microsystems 880 is a prominent series of workstations and servers that played a significant role in the computing landscape during the late 1980s and early 1990s. It was known for its innovative technologies and robust performance, making it a favored choice for both developers and enterprises. The 880 series was powered by the SPARC (Scalable Processor ARChitecture) architecture developed by Sun, which provided enhanced speed and efficiency.

One of the standout features of the Sun 880 was its multiprocessing capability, allowing multiple processors to work simultaneously. This capability ensured high performance for demanding tasks, making it ideal for applications in scientific research, graphics, and large databases. The architecture supported a wide range of operating systems, with SunOS being the most notable, providing a stable and powerful environment for users.

The Sun 880 also incorporated advanced memory management features, including support for virtual memory, which allowed for more effective use of system resources. Users could run multiple applications simultaneously without compromising system performance. The system architecture was designed to handle large amounts of RAM, which was essential for memory-intensive applications, further enhancing its suitability for professional use.

Another characteristic of the Sun 880 series was its modular design, which allowed for easy upgrades and maintenance. This modular approach meant that users could customize their systems according to their specific needs, whether that involved adding more memory, upgrading processors, or incorporating additional storage solutions. The high flexibility made it appealing to businesses that required tailored solutions.

In terms of connectivity, the Sun 880 featured a variety of ports and interfaces, enabling integration with various peripheral devices. This made it possible to connect printers, scanners, and other essential tools, facilitating seamless operation in office environments.

The Sun 880's impressive combination of processing power, expandability, and superior memory management made it a cornerstone in the evolution of workstations and servers during its time. As technology progressed, the Sun 880 helped pave the way for subsequent generations of computing systems, leaving a lasting legacy in the realm of high-performance computing. The architecture and design principles laid down by the Sun 880 continue to influence modern computing technologies today.
