Re: VIOS from scratch -- MIDRANGE-L

Well,
So far i've done the following:
Installed the VIOS (for the 4th time), during the first step i noticed that
you can change the Edition it installs (which is weird, since it should
check with the FSP to see whether Express,Standard or Enterprise is enabled)
extended rootvg to the second disk (got 4x 73Gb xseries disks on the CEC)
enabled mirroring
made sure both disks were added to the bootlist
logged as padmin and accepted the license terms

Now, i went to the HMC, created a virtual Eth device and assigned the first
logical port of the LHEA to the VIOS partition.
I tried to make a SEA (Shared Ethernet Adapter), as per unixguru's video
(good resource, has lots of basic VIOS/HMC tasks):
http://www.dailymotion.com/video/x6t5ve_virtual-ethernet-setup_tech
And this is why i originally created this thread, i couldn't get it to work
(mkvdev command returned a invalid response)
I found this redbook on IVE (Integrated Virtual Ethernet):
http://www.redbooks.ibm.com/redpapers/pdfs/redp4340.pdf
And found the problem:
"If you assign a logical port to a Virtual I/O Server through a physical
port without the
promiscuous mode enabled, the Virtual I/O Server is not able to use the
mkvdev command to
define the SEA. SEA requires HEA as a dedicated adapter, capable of viewing
all network
packets in order to deliver them to all LPARs or to drop them when they do
not belong to the
defined network."
So i went to the HMC and made sure the logical port was set to promiscuous
and assigned to the VIOS partition.
This time, the mkvdev command worked and the SEA got created.
Assigned TCPIP settings per unixguru's video and did a happy dance.

Now i found myself with the task of creating the SCSI adapters and disk
devices.
And again i hit a wall:
All the tutorials and developerworks threads i'm finding talk about AIX.
Do the disks for AIX work for IBM i? i mean, they used to have a 512 to 522
bytes per sector difference that made them incompatible so i suppose i have
to create disks for IBM i with a specific parameter, or does it work with
normal disk devices?

Best Regards!

Pete,

IVM is present whenever you DONT use an HMC, i have a power4 blade (JS21)
gathering dust and i've been meaning to test it with VIOS; but i thought it
better to start with the HMC and the big POWER6 machine...
If i'm not mistaken, you cant access the IVM part of VIOS when the system
is HMC managed, since the HMC takes over those functions.

Best Regards,

My experience has all been on a JS12 Blade but I would think there are
many similarities between VIOS on a Power 6 blade and any other Power 6
hardware. I used the "IBM i on a Power Blade Read-me First.pdf" from
Vess Natchev (IBM) and though much of it applied to getting the blade
configured with the BCS chassis, the section on using the console with
VIOS and the initial configuration steps are very readable (starting
around section 5.2.2)

I pretty much use the IVM for everything and rarely need to go to the
command line in AIX. Is the IVM, a component of PowerVM, not included
on other hardware? The GUI is pretty simple to use and outside of
getting an IP address configured, I don't recall much else in command
line configuring.

Most of these i already had (not the one for expanding the vg and

enabling

mirroring), but it's good to get them all in the same place and with
explanations no less!

I'll explain my problem then, maybe an idea will pop:
This POWER6 has no 5701/5706, it only has the internal 4 port IVE 1Gb

card.

I had found a video tutorial for setting up TCPIP on VIOS but it assumed
you had a real card. the only entX devices i have are from the LHEA

card. i

assigned a logical port from the HMC and created a virtual eth adapter

but

when attempting the mkvdev between them i get "unrecognized error" the
syntaxis is the same as when making a bridge between virtual eth and
5701/5706 cards...
I remember getting TCPIP working (as in, HMC sees VIOS via TCPIP) but

using

a dedicated port on the LHEA card, and i want to make it use the bridge
device...

I'm going to a client tonight so i'll have to leave for next week.

Thanks all, i'll update with info as i get it.

Best Regards,

VIO Server is a learning curve without a doubt, a steep one. A strong

Unix background is really helpful. (all of my partitions are

virtualized

with VIOS so I deal with it quite often)

The best place to look for help is in DeveloperWorks, and don't forget

the AIX forums.

Start a cheat sheet with all the commands you use. Larry suggested,

and I followed the suggestion to use Notepad for all the commands you

use,

setting up the virtual SCSI and other devices. That way you can

copy/paste

from note pad into PuttY.

One word of warning. The shell is just plain awful. Be sure to set

your Putty configuration correctly. Problem is, I have not found

anyone

(or a website) that can really tell me what those settings should be

so I

tinker with them until they work.

midrange-l-bounces@xxxxxxxxxxxx I've been mucking around with a nice
POWER6 that we got cheap from IBM-Remarketing a few weeks ago.
Installed VIOS 2.x and got a feel around. I've found some videos
explaining initial configuration, but the config was not exactly the
same (it assumed i had a non-IVE network card and set up the VIOS-HMC
link and general bridge thru that). Is there a good VIOS from scratch
tutorial anywhere? Also, the HMC reports that this machine has no

5250

capabilities, but it DOES have IBM i capabilities. Would that be like
saying "You have a 1000cpw batch and 0 interactive machine"? I've

read

a lot of manuals and think i have most of the theory behind VIOS

(some

concepts are harder, like the whole IVE-LHEA but not impossible).
Infocenter has not been kind to me since it seems only CE work at

this

level (weird since i remember a big client that had its people

trained

to reinstall VIOS in case of disaster). That's about it, if anyone

has

experience with this, feel free to share. I can be more specific

about

the problems i'm having but i would rather read the book than nag
someone. Best Regards,
