Sun Microsystems 1800 manual Initializing the Volume Manager

Page 83

These commands create a startup script that enables the Volume Manager to exit back to the OBP upon encountering a stale boot plex, allowing the Volume Manager to try alternative boot disks.

Enabling Recovery Behavior and Boot Disk Detection

To enable correct recovery behavior and boot disk detection, make the following changes to the startup file /etc/rc2.d/S95vxvm-recover:

#vxrelocd root & commenting out this line enables correct recovery behavior

#start the boot disk utility the following line enables boot disk detection

/usr/platform/SUNW,Ultra-4FT/SUNWcms/lib/vxbootcheck &

Make the edits exactly as shown, commenting out the vxrelocd line and with the complete path to vxbootcheck. Be sure to append an ampersand to the vxbootcheck line.

The default behavior of Sun StorEdge Volume Manager when a physical disk fails is not compatible with the hot-plug of HDD modules on the Netra ft 1800. By default, when the Volume Manager detects I/O failure on mirrored volumes, it restores redundancy by relocating the objects to spare disks. This is called hot relocation. You need to disable this default behavior. By commenting out the vxrelocd line, as shown above, you prevent hot relocation.

You must repeat all these modifications after system upgrades.

Initializing the Volume Manager

When you have loaded the Sun StorEdge Volume Manager, run vxinstall as described in the Sun StorEdge Volume Manager Installation Guide. This section describes the special actions you must take to initialize the Volume Manager for the Netra ft 1800.

Note –Volume Manager mirroring provides the fault tolerance for disk storage on the Netra ft 1800. This is provided by default when you add a disk to the Volume Manager provided you have added the required line to /etc/default/vxassist as described in “Setting Default Volume Creation” on page 68.

1800 specifications

Sun Microsystems, founded in 1982, unveiled an array of innovative products over the years, among which the Sun-1 workstation and later the Sun-1800 series were significant contributions to the technology landscape. Designed specifically for engineering, graphics, and computing tasks, the Sun-1800 series emerged during a period when workstations were essential for high-performance computing applications.

The Sun-1800 series was powered by the SPARC architecture, which became a hallmark of Sun Microsystems' technological advancement. SPARC, an acronym for Scalable Processor Architecture, allowed the system to achieve high levels of performance and efficiency, positioning it well against competitors in the workstation market. The SPARC processors used in the Sun-1800 series enabled faster computation and multitasking, making it well-suited for scientific applications, computer-aided design (CAD), and complex data analyses.

One of the standout features of the Sun-1800 series was its expansive memory capabilities. Supporting configurations that could house up to 128 megabytes of RAM, the workstations were excellent for handling large datasets that were prevalent in research and corporate environments. This high memory capacity, combined with the efficient use of the SPARC architecture, granted users access to significant computational power, which was crucial for multitasking in complex job environments.

The Sun-1800 series also emphasized networking capabilities, with integrated Ethernet support. This allowed users to seamlessly connect their workstations into local area networks, facilitating collaborative projects and data sharing among teams. The use of the Solaris operating system, which was based on UNIX, also provided a robust and stable environment for enterprise applications, making the Sun-1800 ideal for business-critical applications.

Moreover, the system was designed to support various programming languages and development tools, attracting engineers, scientists, and software developers alike. Sun Microsystems also focused on providing high-quality graphics support, with advanced graphical capabilities that enabled users to engage in advanced visualization tasks, such as 3D modeling.

In summary, the Sun Microsystems 1800 series stands out for its powerful SPARC architecture, impressive memory capacity, integrated networking, and robust graphic capabilities. These characteristics, combined with the reliability of the Solaris operating system, positioned the Sun-1800 as a favored choice among professionals in engineering and scientific fields, shaping the future of workstation computing.
