Install/Upgrade



Booting SCO_OSR5- Filesystems Just about anything you are going to do with a computer involves files. Unix in general treats just about everything as a file: devices, directories, named pipes- they are all just files. Other OS's don't necessarily do that; for example there's no visible /dev directory on a Windows system-though if you are programming in "C", for example, you can open "/dev/lp" and print to it just as you would in Unix! Besides that, though Windows doesn't usually let you have direct access to its devices: a tape backup program, for example, knows how to write to your tape drive, but you'd have no way to directly access it yourself as you do in Unix. The concept of "everything is a file" is one of the distinguishing characteristics of Unix systems. Files are created on filesystems, filesystems are created on divisions (SCO's terminology) and divisions are created within partitions.

SCO/Linux Transition Guide   2000 09 
- This is not a porting guide; this is a transition guide: a guide to the major differences between SCO and Linux that anyone familiar with one may find confusing about the other. As both OS'es are themselves always in transition, some of this material will change quickly. I'll keep it up to date as best I can, of course. Mostly this article concerns SCO OSR5 and not Unixware; in some places I've noted differences but not always. -
Linux|Unix Logical Volume Manager (LVM) on Software RAID   2002 11  2011/01/07 TonyLawrence
- Logical Volume Manager is now included with most Linux distributions. The RedHat 8.0 installer even allows you to create LVM volumes during initial install. LVM offers capabilities previously only found in expensive products like Veritas. If you plan on using LVM, I really recommend doing so on a RAID system, either hardware or software -
Numeric Unix Error Messages   2001 12  2010/04/06 TonyLawrence
- It's an unfortunate fact that many programmers are lazy about error messages. Very often, all you get is a cryptic "Error 5", and you may be lucky to get that. -

Software Mirroring on RedHat 8.0   2002 11 
- I installed RedHat 8.0 on a spare machine here to see how the software raid works. I have always used hardware raid in the past, but various internet articles and posts convinced me that Linux software raid wasn't a Bad Thing. I do think I still prefer hardware raid, though. BTW, always remember that raid is no substitute for regular and reliable backup! -

Redhat Linux 6.1   1999 10 
- Red Hat 6.1 is now available. I was out buying a book or something the other day and saw it on the shelf, so I picked it up and finally got to it this weekend. As I already had a 6.0 installation in place, I decided to try the "upgrade" option. I really have no need to do this; the Red Hat machine is just a "test and play" box, so I could have just wiped it out and started fresh, but I wanted to see how well the upgrade would work. Unfortunately, at first it didn't work well at all. -

Performing OS Upgrades   1998 08 
- I think most of us tend to delay upgrades. There is the natural fear of untested software, the expense and the time and trouble required. -
Booting SCO_OSR5   1999 12 
- PC Bootstrap: I'm ignoring the POST (Power On Self Test) routines and anything else (security checks, etc) that might be built into your machine. Obviously all of that happens prior to boot, but isn't important for this article. -
Understanding RAID   1999 03 
- Today anyone with high disk performance needs or concerns about data reliability should consider some sort of RAID configuration. -

Transferring Data from an Old Hard Drive   2001 03 
- The machine I had installed in 1993 had developed a problem with the hard disk controller. I checked with the manufacturer and they had never even heard of EISA SCSI controllers. -
Installing an Equinox SST-64 under Linux   2001 03 
- A couple weeks ago after 15-20+ hours work I got my Equinox sst-64 pci card working so I could log in thru terminals. I'm sending info on what I did [most from notes, some from fading memory] in case it is useful to others. -
Installing SCO OSR5.0.6   2001 02 
- Installing and configuring SCO 3.2v5.0.6: First order of business was to install the 29160 controller. Ooops, no 64 bit PCI slots in this machine. Hmm, what was I thinking? Oh, yeah, I was planning to use another, newer machine that does have those slots. But since then, that machine has become the machine my wife uses. See what happens when you delay these things? -
Hard Disks   2001 02 
- The most common hard drives today are IDE or SCSI. IDE drives are generally less expensive (though not by much) and generally not as fast (again, not by much). IDE systems are limited to two drives per controller, which means that you probably cannot have more than 4 IDE drives in one system. With SCSI, you can have 15 (or 7 with older controllers). -

Unixware 7 Non Stop Clusters   2000 02

Booting SCO_OSR5- CPU   1999 12 
- I think it's unfortunate that most programmers and administrators don't have much knowledge of hardware or indeed much interest in it. -
Booting SCO_OSR5- Swap and Dump   1999 09 
- Normally, the swap and dump device are identical. You could change that by editing the file /etc/conf/cf.d/sassign and relinking a new kernel. -
Getting Linux Up and Running in my Office   1999 05 
- There's plenty of controversy in the SCO community concerning Linux. Some see it as the death knell for SCO, others as a positive force, others as something in between. No matter what you think, you probably agree that learning something about it is important. -

ipu vs. fresh install   1997-2004 
- I would like IPU's a lot better if they would produce a full directory hierarchy diff of the upgraded system vs. the pre-upgrade system (or against what a fresh install would have produced), and a diff of all files preserved or merged against the fresh versions that otherwise would have been installed. -
oss653a cn.primary   1997-2004 
- Your problem with the oss653a BTLD is this: you're trying to boot-time link it into your fully linked kernel. The boot-time linker has limited memory (it's a 'compact' model 8086 Xenix binary). It can't handle the symbol table of a fully linked kernel. To use a BTLD _as_ a boot-time linked driver, you must use it with the install kernel from an OSR5 install floppy or CD. -
unusable space in fdisk   1997-2004 
- You have only 4 primary partitions available and you have used all of them. Thus although there is space available, there is no partition toput it in! It's unusable. -
