a.If no failures occur, the command exits with no output.

b.If failures occur, you might see one of the following messages:

CODE EXAMPLE 9-5Sun StorEdge T3+ Array Failure Codes

#/opt/SUWNsecfg/bin/failbackt3path -n t3b0

MultiPath failback command failed. Returned Result = 513

#/opt/SUWNsecfg/bin/failbackt3path -n t3b0

MultiPath failback command failed. Returned Result = 586

The message return code 513 indicates that the Sun StorEdge T3+ array did not require a failback. The message return code 586 indicates that the Sun StorEdge T3+ array failback could not be completed because the primary path could not be reached.

3.If you encounter the return code 586, check the switches sw2a and sw2b and make sure the ports associated with the Sun StorEdge T3+ array and virtualization engines are online.

In this example:

a.t3b0 should be plugged in to port 2 (on a 1 Gbit switch) of both sw2a and sw2b (port 1 on a 2 Gbit switch)

b.The virtualization engine should be plugged in to port 1 (on a 1 Gbit switch) of the same two switches (port 0 on a 2 Gbit switch).

Refer to the Sun StorEdge 3900 and 6900 Series 2.0 Reference and Service Guide to determine which switch ports are used for each component.

4.Run the showswitch(1M) command for sw2a and sw2b.

5.Look at the output sections "Port Status" and "Name Server" to see if the ports are online. The output will look like that in CODE EXAMPLE 9-6if there are no problems.

6900, 3900 specifications

Sun Microsystems was a pioneering force in the computer industry, especially known for its innovative workstations and servers during the late 20th century. Among its notable product lines were the Sun 6900 and 3900 series, which played a critical role in enterprise computing, offering substantial advancements in performance and reliability.

The Sun 6900, also known as the Starfire, was an advanced multiprocessor server introduced in the mid-1990s. One of its standout features was its ability to support up to 64 processors, making it one of the most powerful systems of its time. This scalability was made possible by Sun’s innovative design, which utilized a high-bandwidth crossbar switch architecture that facilitated fast communication between processors, ensuring minimal latency and optimal performance for demanding applications.

The 6900 was built on the UltraSPARC architecture, which provided support for 64-bit processing. This was a significant advancement over 32-bit systems, allowing for improved memory addressing and overall application performance. The server supported large amounts of RAM, up to 512 GB, which was critical for memory-intensive tasks such as database management and scientific computation.

On the other hand, the Sun 3900 series catered to a different segment of the market, targeting businesses requiring robust, yet cost-effective server solutions. The 3900 was designed primarily as a mid-range server and offered impressive reliability features such as hot-swappable components and redundant power supplies. It came equipped with the SPARC architecture, ensuring compatibility with a wide array of software applications.

Both the 6900 and 3900 series made extensive use of Sun’s Solaris operating system, which was known for its stability and security. This operating system allowed for seamless multitasking and efficient resource management, a necessity for enterprise environments where uptime was critical.

In terms of connectivity, both systems supported advanced networking capabilities, including Fast Ethernet and Gigabit Ethernet options, facilitating improved data throughput. Their modular designs allowed for easy upgrades, ensuring that organizations could adapt to changing technological demands without major overhauls.

Overall, the Sun 6900 and 3900 series represented a significant leap forward in server technology, combining powerful processing capabilities, advanced scalability, and reliable performance. These systems played a crucial role in establishing Sun Microsystems as a leader in the enterprise computing arena during their era.
