Perhaps, but you've also got this wrong: dasdfmt -v -b 4096 -l TEMP -f /dev/dasde1 You want to specify -f /dev/dasde instead. You're formatting the device, not a partition. Making file systems is when you specify a partition number.

Re: Linux Restart
If the Marist dist directs local7 to /var/log/boot.log you can look there for possible clues as well. Also, /var/log/messages might be worth a look see for any events that might be blowing your configuration away. Now that you have it running, and can correct it in the event that it fails, you can try running the command: /etc/init.d/network restart from a root prompt to see if you can catch a message.

DASDFMT Fails (invalid argument)
I am running RedHat 3.1 on VM 4.4. in and LPAR (of course) on an IFL. I want to add a disk. A minidisk addr 204 of 5008 cylinders was added.

Re: Linux Benchmark
You're making the same mistake everyone does -- comparing apples to wildebeests. Mips are not mips. We go through this every few months, so here it is again: S390 machines are VERY good at handling I/O but are relatively slow in compute power. Intel machines are fast at raw compute power but are very slow in I/O handling. Intel has to do ALL the computing and I/O with its central processor, and probably spends 90% of its time handling I/O. You're comparing the total processing power of an intel box against the central processor only of a mainframe. a 350 mips z800 (we have one) is just the central processor. By the time you add in the processing capability of the channel processors and the processors inside the control units, you might raise that 350 mips to around 30,000 mips -- but only for I/O intensive jobs! If your application is compute intensive (beowulf clusters,engineering calculations, lots of Java), use Intel or HP. If it's I/O intensive (databases, network infrastructure, web processing) the s390 will beat it hands down from Sunday. You also need to consider the cost-per-computing power ratio. My personal pet peeve in our company is when someone sets up a database on a "fast" distributed machine running Unix or Windows, then finds out the "fast" machine can't handle the load, so they bring in another processor to "mirror" the data to allow more people to access it simultaneously. Any time you have 20 copies of the same data being updated, AT LEAST 19 of them will be wrong! Why not put it on a machine that can handle the load in the first place?

Well, since the "M" stands for "meaningless" I would say it's not terribly relevant. Still, using Barton's famous "number" of 4, I think 17.5 MIP translates to about a 72MHz Intel system.

Re: Linux Benchmark
What do you suppose 100% of all the 'mips' of your intel box is, vs 5% of one 350 mip engine? You are getting a MAX of 17.5 mips based on the 5% equation. 17.5 million instructions per second SOUNDS like a lot, but when you compare it to having 100% of your intel box it's peanuts. But, you have lotz-o-mips for I/O on a z/box or a s/390 machine, and that is where it excels Ranga Nathan <[EMAIL PROTECTED] l.com> To Sent by: Linux on [EMAIL PROTECTED] 390 Port cc <[EMAIL PROTECTED] IST.EDU> Subject Re: Linux Benchmark 05/21/2004 01:54 PM Please respond to Linux on 390 Port <[EMAIL PROTECTED] IST.EDU> I find my Linux LPAR very very slow, even though it has 5% of a 350mips z/800.

This, while a little misleading, is not incorrect. The portname, while
optional,
MUST be the last parameter if it is specified. Not specifying the
portname should
not cause any problems, and is probably the better way to go. That way if
someone
changes it on some other system using the device, it won't break the
VSWITCH's
ability to use the OSA.

The SYSTEM CONFIG file is the better place to grant access.

Since this TAO system will be used as a sandbox system (or possibly a rescue system), I will probably experiment with the other connection types.

Re: FW: VM TCPIP (A Little Off Topic)
Steve, I discussed this in the VSWITCH and VLAN Redpaper which you can find
at:
http://www.redbooks.ibm.com/abstracts/redp3719.html
I'd be keen to hear what you think of it, so please let me know or use the
feedback e-mail address on the Redbooks site.
Cheers,
Vic Cross
An interesting finding and a question; you use the term "must" with respect
to configuring the PORTNAME option of DEFINE VSWITCH when it appears to be
optional parameter. I might be taking this out of context as the statements
made only refer to the placement of the PORTNAME parameter ("PORTNAME must
be the last parameter") but it reads like this parameter is not optional. I
find that it really isn't necessary to address the port name when defining a
functional switch but it might be prudent to do so. Is there any situation
that you can think of where not addressing the OSA port name in the switch
definition might trip someone up?
Also, when configuring the TCPIP service machines to autolog, I find it
helpful to put the MODIFY VSWITCH GRANT statements in SYSTEM CONFIG instead
of using CP SET VSWITCH GRANT from the profile of AUTOLOG1. This saved me a
lot of typing yesterday when AUTOLOG1 didn't start forcing me to manually
start the Controller service machines (still researching why AUTOLOG1 didn't
start). You do make mention of configuring access to the switch through CP
SET VSWITCH but not through MODIFY. Do you see a disadvantage to making use
of MODIFY from SYSTEM CONFIG in this manner?
The paper is well organized, well written and proved to be very helpful to
my configuration efforts. I found the general discussion on VLANs and how CP
implements them informative and complete. This is very good work.
Thanks Vic

Linux Reference Architecture document
Hello all, I am finally getting to the point around here where I can actually mention Linux, especially on S/390, without getting major resistance to the idea. And there may be a major business case waiting in the wings. But I digress Does anyone have a good Reference Architecture or Best Practices document for all (or one) platform(s) that I could modify to suit my own purposes? I am already late to the party and am looking for ways to pick up speed and to set the proper strategic direction. Granted, there are a lot of variables (and opinions) in documents of this sort, but I do not even know where to start in the development of my own. Hence my request.
