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 – Foundation for future 4

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? – IBM i POWER External Storage Support Matrix Summary •

Installing VIOS • Current install method – A bit alien if you don’t have AIX experience ...
7
© 2013 IBM Corporation
Install via SMS • Create a partition for VIOS • Activate the partition • Select SMS for Boot mode
8

4
And then… • Press 0 to select console

Easier Install via HMC GUI • HMC enhancement – V7R7.7.0 SP1 • Readme - http://www933.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 • See AIXpert blog entry: • https://www.ibm.com/developerworks/community/blogs/aixpert/entry /upgrading_to_hmc_v7r770_upgrade_to_service_pack_2_immediat ely?lang=en

Let’s begin with HMC
13

Create partition profile

Activate the VIOS partition

Installing from Local Repository Assumes you will boot over the network as the install image is on HMC – need to ensure that networking is setup correctly
NIM Server IP Address is the ip address of the HMC. Here the image VIOS_V2.2.2 has been previously imported 17

Import install image from HMC’s DVD or remote NFS or SFTP server If you click on Import, you have following options :
Remote SFTP server
HMC’s DVD drive
Remote NFS server
18

Or via HMC Management task…

Local Repository example
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!)

10
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

Install process begins…

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 /var/log/nimol.log

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
26

13
As hdisk0 was not available… Select the disk to install to…
