receiving power. To determine if a fan is faulty, check its fan speed displayed in the prtdiag output. A fan speed of zero should be interpreted as a fan failure. Also, any fan failure will light the fan tray’s Fault LED and the System Fault and Thermal Fault LEDs on the server’s front panel.

Note Patch 110849-08 or later fixes this issue. See “Required And Recommended Software Patches” on page 3.

hsfs: hsnode table full (BugIDs 4082275, 4475306)

For a Sun Fire 880 system running the Solaris 8 7/01 operating environment, if you attempt to set up the system as a Solaris install server, the following error message may appear during installation of the install server packages or patches:

NOTICE: hsfs: hsnode table full

If this message appears, the software installation will terminate prior to completion, and the install server software will be only partially installed.

Workaround – To recover from this situation, add the following line to the /etc/system file and reboot the system:

set hsfs:nhsnode=1000

Once the system has booted, repeat the procedure for setting up the install server.

Intermittent picld errors during power supply hot-plug (BugID 4431165)

On Sun Fire 880 systems running the Solaris 8 7/01 or 8 10/01 operating environment, the following picld error messages may be temporarily generated after hot-swapping a redundant power supply:

ERROR running psvc_ps_device_fail_notifier_policy_0 No such device or address

ERROR running psvc_ps_overcurrent_check_policy_0 No such device or address

These warnings do not indicate a problem with the server or power supply. For a brief time during the hot-swap operation, the environmental monitoring software is unable to monitor the environmental conditions of the power supply, which results in the error messages. This state is temporary, however, as full monitoring capabilities are restored within 30 seconds.

Note Patch 110849-08 or later fixes this issue. See “Required And Recommended Software Patches” on page 3.

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.
