2.Allow the system to remain at the ok prompt for at least 10 minutes to ensure that the two backplanes are loaded with the same version of firmware.

The system automatically synchronizes the firmware versions between the two backplanes.

3.After the required waiting period, boot the system to single-user mode.

ok boot -s

4.To verify that the firmware synchronization process has successfully completed, type the following luxadm subcommand:

#luxadm display enclosure_name

Where enclosure_name is the enclosure name assigned to the Sun Fire 880 internal storage array—by default, FCloop. If you need to verify the enclosure name first, use the luxadm probe subcommand.

The output of the display subcommand shows the status of each SSC100 in the system. The following is an excerpt of sample output for a dual-backplane system.

SSC100’s - 0=Base Bkpln, 1=Base LoopB, 2=Exp Bkpln, 3=Exp LoopB

SSC100 #0: O.K.(9224/ 120A)

SSC100 #1: O.K.(9224/ 120A)

SSC100 #2: O.K.(9224/ 120A)

SSC100 #3: O.K.(9224/ 120A)

Verify that each SSC100 processor displays an “O.K.” status and that each displays the same firmware version in parentheses. If so, the firmware synchronization process has successfully completed. Otherwise, wait another two minutes or so and repeat this step.

Note For more information about the luxadm utility, see Platform Notes: Using luxadm Software, part of the Solaris on Sun Hardware AnswerBook2 Set on the Supplement CD.

5.Once the firmware synchronization process is complete, you can restore the system to multi-user mode.

For example, type:

#init 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.
