Virtual I/O Server – What?
•
What is VIOS?
– Appliance - runs in a partition on a POWER6/7 server or blade
– Provides virtual resources to AIX, Linux, and IBM i (i7.1/i6.1) client partitions
– Facilitates sharing of physical I/O resources between partitions
– Core function is virtual I/O: disks, tape, optical, Ethernet
– VIOS packaged in PowerVM
– Advanced functions (Suspend/Resume, LPM, AMS, NPIV, etc)
– Two Virtual I/O Server partitions recommended to provide redundancy
– Partitions can have a mix of physical and virtual resources
• Except blades/PureFlex, and certain functions e.g. LPM
Virtual I/O Server – Why?
• Why use VIOS?
– Benefits of virtualisation
Increased utilisation
+
Improved service
+
Improved flexibility
=
Reduced costs (hardware, floor space, energy, licensing)
– Faster response to changing business need – flexible
infrastructure

To VIOS or not to VIOS…
•
It depends!
•
VIOS not usually the best match with IBM i when
– Using only internal disks
– Only running a single partition
•
VIOS is often a good match with IBM i when
– There are many partitions
– Multiple operating system environments e.g. IBM i and AIX / Linux
– Creating/deleting partitions often e.g. for testing
– Requirement to attach to certain external storage (wider range supported via VIOS
than direct attach)
•
If all partitions to run IBM i only
– Consider strategy, advanced functionality requirements, etc
– Is VIOS still best option?
– Is IBM i hosting IBM i sufficient?
•
There are always exceptions to above
External Storage
• Wider range of external storage supported
with VIOS than with native IBM i attach
• What is supported?

Installing VIOS
• Current install method
– A bit alien if you don’t have AIX experience ...
Install via SMS
• Create a partition for VIOS
• Activate the partition
9 © 2013 IBM Corporation
And then…
• Press 0 to select console
Next…

And so on…
And so on…..
Easier Install via HMC GUI
• HMC enhancement
– V7R7.7.0 SP1
• Readme -
http://www-933.ibm.com/support/fixcentral/firmware/readme?fixid=MH01343#e
nhance
• “Add a GUI enhancement for the installation of VIOS, allowing the
user to install the Virtual I/O Server and managing Virtual I/O Server
images using a GUI interface.”
– SP2 recommended

Let’s begin with HMC

Activate the VIOS partition

Notice that the ‘Open a terminal window’
checkbox is greyed out

Installing from Local Repository
NIM Server IP
Address is the ip
address of the
HMC.
Here the image
VIOS_V2.2.2 has
been previously
imported
Assumes you will boot over the network as the
install image is on HMC – need to ensure that
networking is setup correctly
Import install image from HMC’s DVD or
remote NFS or SFTP server
If you click on Import, you have following options :
HMC’s DVD drive
Remote NFS server
19 © 2013 IBM Corporation
Or via HMC Management task…

If you desire to change adapter setting,
click Advanced first (when you get back to
this screen, the values seems to be
blanked out again, and you have to re-fill!)

VIOS ip settings
Enter the ip information for the
VIOS server – this will be used
to configure networking on the
VIOS server as part of the
install… and click OK
23 © 2013 IBM Corporation
And progresses…
The screen auto-refreshes!
Hint:
For better scrollable
view - click on the
‘bookmark’ star – this
bookmarks the page.
Open browser and go
to that recently
bookmarked page
OR
ssh into the HMC and
check
25 © 2013 IBM Corporation
Easy to scroll and manually refresh
Usually…
• Auto-selects disk to install VIOS to
– hdisk0 usually
– proceeds without user interaction
• In my test a problem with hdisk0
– So then you need to open a terminal window
and follow the prompts to select a disk
27 © 2013 IBM Corporation
As hdisk0 was not available…
Select the disk to install to…
29 © 2013 IBM Corporation
And completes
Login prompt
Installing from DVD
Can also install from
the HMC’s DVD drive
