Setting Up a SPARCstation

A gentle introduction to Sun Workstations and installing Red Hat Linux SPARC 4.0.

The SPARC-Linux installation requires that you create a “whole disk” partition (file system type “5”), spanning from cylinder 0 to the last available cylinder. Root, swap and /usr partitions are created in the normal way and overlap this “whole disk” partition.

As you can see, SPARC-Linux also numbers cylinders from 0, rather than the i386 Linux default of 1.

4.0 Specifics

If your initial install is from a 4.0 CD-ROM, there are a few things which you need to know (see Red Hat's errata list for up to date information). You really should update your kernel as soon as possible to circumvent a particularly nasty networking bug which plagued the 2.0.18 kernel shipped with this release. The problem causes random hangs and crashes, especially when the machine is attached to a network where IPX packets are also present. When updating the kernel on your system, be sure to update the kernel loadable modules, too. New kernel and module packages are available in Red Hat's RPM package format on their FTP server, or alternatively, you can get a binary “snapshot” of the latest kernel from vger.rutgers.edu (see Table 2).

Another problem which can be perplexing if you don't know about it beforehand is the dump program. This slipped into the distribution without having been checked for “endian-ness” and consequently behaves very strangely indeed, complaining about seeks to negatively numbered sectors and blocks. Again, an updated dump package is available from the Red Hat site. Version 0.3-5 or greater should work.

Wrap-up

As I write this, a group of folks are putting together the first Debian release of SPARC Linux. However, Red Hat is the only complete packaged release available on CD-ROM. While Red Hat's initial, 4.0 release suffered from a few teething problems, it has brought SPARC Linux into the mainstream Linux arena, rather than being confined to a backwater as something of an oddity. The worst of the problems have been fixed in 4.1, and this newer release also comes at a much more attractive price. The availability of both versions via FTP and on other vendors' compilation CD-ROMs is adding to the popularity of this architecture, and the installed base is spreading rapidly as evidenced by the increased traffic on the SPARC Linux mailing list. While I.T. professionals may still be reluctant to migrate the whole of their user base to SPARC Linux, there certainly seem to be a growing number of organizations out there who have one or two systems at least under evaluation. Many more old SPARC workhorses are getting a new lease on life with Linux and popping up on the Internet as FTP and Web servers.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
