Setting up Boot Disks

You must encapsulate the boot disk for Sun StorEdge Volume Manager to be able to mirror it. You are strongly recommended to do the following to ensure that the boot disk is configured for the Netra ft 1800:

Assuming that A-DSK0is the Solaris install disk, you should have entered the command shown below at the end of the Solaris installation. See eeprom (1) for details on using eeprom command to change the boot device.

#eeprom boot-device=a-dsk0 diag-device=a-dsk0

Encapsulate the boot disk when the vxinstall process asks whether you want to do so.

To mirror this root disk, add another disk, for example, b-dsk0, as a new disk.

See the Sun StorEdge Volume Manager Installation Guide for details of how to do this during the vxinstall process.

The vxinstall process proposes the rootdg disk group by default. Accept this to add the boot disk and disks intended to mirror the boot disk to this group.

When the vxinstall process is complete, use the vxdiskadm utility to make the new disk a mirror of the boot disk, for example, make b-dsk0a mirror of a-dsk0.

To start vxdiskadm:

#vxdiskadm

Select option 6, Mirror volumes on a disk.

See the Sun StorEdge Volume Manager System Administrator’s Guide for full details of using vxdiskadm.

Note To assist recovery of data in the event of disk failure, use the boot disk only for data required to boot the system. Do not add user-data disks to the rootdg group.

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.
