TABLE 6-10

In addition, the OpenBoot Diagnostics tests use a special variable called test-argsthat enables you to customize how the tests operate. By default, test-argsis set to contain an empty string. However, you can set test-argsto one or more of the reserved keywords, each of which has a different effect on OpenBoot Diagnostics tests. TABLE 6-3lists the available keywords.

TABLE 6-3Keywords for the test-argsOpenBoot Configuration Variable

Keyword

What It Does

 

 

bist

Invokes built-in self-test (BIST) on external and peripheral devices

debug

Displays all debug messages

iopath

Verifies bus/interconnect integrity

loopback

Exercises external loopback path for the device

media

Verifies external and peripheral device media accessibility

restore

Attempts to restore original state of the device if the previous

 

execution of the test failed

silent

Displays only errors rather than the status of each test

subtests

Displays main test and each subtest that is called

verbose

Displays detailed messages of status of all tests

callers=N

Displays backtrace of N callers when an error occurs

 

• callers=0—Displays backtrace of all callers before the error

errors=N

Continues executing the test until N errors are encountered

 

• errors=0—Displays all error reports without terminating testing

 

 

If you want to make multiple customizations to the OpenBoot Diagnostics testing, you can set test-argsto a comma-separated list of keywords, as in this example:

ok setenv test-args debug,loopback,media

From the OpenBoot Diagnostics Test Menu

It is easiest to run OpenBoot Diagnostics tests interactively from a menu. You access the menu by typing obdiag at the ok prompt. See “How to Isolate Faults Using Interactive OpenBoot Diagnostics Tests” on page 177 for full instructions.

The obdiag> prompt and the OpenBoot Diagnostics interactive menu (FIGURE 6-4)

appear. For a brief explanation of each OpenBoot Diagnostics test, see in “Reference for OpenBoot Diagnostics Test Descriptions” on page 109.

V490 specifications

Sun Microsystems V490 is a robust, high-performance server that was launched in the mid-2000s. It is part of Sun's Enterprise line of servers, specifically designed to meet the needs of businesses requiring reliability, scalability, and efficiency in their computing environments. The V490 is well-regarded for its versatility and ability to handle demanding applications.

At the heart of the V490 is its support for the UltraSPARC IV processor. The server can be configured to contain up to four processors, allowing it to deliver exceptional parallel processing capabilities. The UltraSPARC IV architecture enhances throughput and efficiency, making it suitable for enterprise applications and database management tasks.

One of the standout features of the V490 is its memory capacity. The server can support up to 64 GB of RAM, which allows for extensive caching and improved performance for memory-intensive applications. Coupled with a high bandwidth architecture, the V490 ensures that data can be processed quickly and effectively.

The V490 also emphasizes storage flexibility. It comes equipped with multiple disk drive bays, allowing for a combination of SATA and SAS drives. This flexibility enables businesses to tailor their storage solutions according to their specific performance and redundancy requirements. The V490 supports hot-swappable drives, making maintenance and upgrades considerably easier without taking the server offline.

In terms of connectivity, the Sun V490 features a variety of networking options. It includes multiple Gigabit Ethernet ports, ensuring high-speed data transfer and redundancy. Additionally, the server supports advanced input/output capabilities, making it compatible with various peripherals and external storage solutions.

Sun Microsystems V490 runs on the Solaris operating system, known for its stability and security. This OS enhances the server's performance while providing a reliable platform for mission-critical applications. The V490 also supports virtualization technologies, allowing organizations to run multiple operating systems and applications on a single hardware platform, thus optimizing resource utilization.

Another key characteristic of the V490 is its thermal efficiency. The server is designed with an advanced cooling system that minimizes energy consumption while maximizing performance. This focus on power efficiency aligns with modern data center requirements for sustainability and reduced operational costs.

In summary, the Sun Microsystems V490 is a powerful enterprise server that combines the latest processing technologies, substantial memory and storage capabilities, and robust networking options. Its scalability, along with advanced virtualization support and energy-efficient design, makes it a suitable choice for organizations looking to enhance their IT infrastructure. The V490 remains a testament to Sun Microsystems' commitment to delivering high-quality, reliable computing solutions.
