7 Scenario A (one VIO server)

8 Scenario B (two VIO servers)1 IBM Virtual I/O Server

The Virtual I/O Server is part of the IBM eServer p5 Advanced Power Virtualization hardware feature. VirtualI/O Server allows sharing of physical resources between LPARs including virtual SCSI and virtual networking.

This allows more efficient utilization of physical resources through sharing between LPARs and facilitates

server consolidation.

2 InstallationYou have two options to install the AIX-based VIO Server:

1. Install from CD

2. Install from network via an AIX NIM-Server

Installation method #1 is probably the more frequently used method in a pure Linux environment as installationmethod #2 requires the presence of an AIX NIM (Network Installation Management) server. Both methods

differ only in the initial boot step and are then the same. They both lead to the following installation screen:

3 Initial setup

After the reboot you are presented with the VIO-Server login prompt. You can't login as userroot as you have

to use the special user id padmin. No initial default password is set. Immediately after login you are forced toset a new password.

[compat]: 3004-610 You are required to change your password.Please choose a new one.

padmin's New password:Enter the new password again:

The following file has been updated: .profileChanges will take affect at next login.

Before you can do anything you have to accept the I/O Server license. This is done with the license command.

$ lsmapThe I/O Server license must be accepted before running this command.Only the chlang command may be run before accepting the license.To view the license, run the license command with the -view option.If the -lang flag is not specified the license will by displayed inthe current locale (set by the chlang command). If the license is notavailable in the language selected, English will be the default.To accept the license, run the license command with the -accept option.

Locale currently set to: "en_US".

Usage: license [-view] [-accept] [-lang Name]license [-ls]

View and accept the I/O Server license agreement.

-accept Accept the license agreement.-lang Specifies the language-territory (locale name) the license

is displayed in.-ls Lists available locales.-view Displays the license agreement.

Please enter:

license -accept

Before you start to define and assign resources please make sure you have the latest version and updates

installed before you proceed. Updates and support for the AIX-based Virtual I/O Server can be obtained at:

IBM VIO Server Page 10 of 123.1.1.1 Virtual I/O Server commands

Once you are logged in as user padmin you find yourself in a restricted Korn shell with only a limited set of

commands. You can see all available commands with the command help. All these commands are shell aliases

to a single SUID-binary called ioscli which is located in the directory /usr/ios/cli/bin. If you are familiar withAIX you will recognize most commands but most command line parameters differ from the AIX versions.

As there are no man pages available you can see all options for each command separately by issueing the

command help . Here is an example for the command lsmap:

$ help lsmapUsage: lsmap {-vadapter ServerVirtualAdapter | -plc PhysicalLocationCode |

-all}[-net] [-fmt delimiter]

Displays the mapping between physical and virtual devices.

-all Displays mapping for all the server virtual adapterdevices.

-vadapter Specifies the server virtual adapter deviceby device name.

-plc Specifies the server virtual adapter deviceby physical location code.

-net Specifies supplied device is a virtual serverEthernet adapter.

-fmt Divides output by a user-specified delimiter.

A very important command is oem_setup_env which gives you access to the regular AIX command line

interface. This is provided solely for the installation of OEM device drivers.

Only the commands necessary for the setup of our defined scenarios (see chapter XXX) will be described next.

4 Virtual SCSI setup

To map a LV

mkvg: creates the volume group, where a new LV will be created using the mklv command lsdev: shows the virtual SCSI server adapters that could be used for mapping with the LV

mkvdev: maps the virtual SCSI server adapter to the LV

lsmap -all: shows the mapping information

To map a physical disk

lsdev: shows the virtual SCSI server adapters that could be used for mapping with a physical disk

mkvdev: maps the virtual SCSI server adapter to a physical disk

lsmap -all: shows the mapping information

5 Virtual Ethernet setup

To list all virtual and physical adapters use the lsdev -type adapter command.

$ lsdev -type adaptername status description

Choose the virtual Ethernet adapter we want to map to the physical Ethernet adapter.

$ lsdev -virtualname status description

ent2 Available Virtual I/O Ethernet Adapter (l-lan)vhost0 Available Virtual SCSI Server Adaptervhost1 Available Virtual SCSI Server Adaptervhost2 Available Virtual SCSI Server Adaptervhost3 Available Virtual SCSI Server Adaptervsa0 Available LPAR Virtual Serial Adapter

The command mkvdev maps a physical adapter to a virtual adapter, creates a layer 2 network bridge and

defines the default virtual adapter with its default VLAN ID. It creates a new Ethernet interface, e.g., ent3.


12/12

IBM VIO Server Page 12 of 12Make sure the physical and virtual interfaces are unconfigured (down or detached).

6 Scenario A (one VIO server)

Create a shared ethernet adapter ent3 with a physical one (ent0) and a virtual one (ent2) with PVID 1:

$ mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid 1ent3 Availableen3et3

This has created a new shared ethernet adapter ent3 (you can verify that with the lsdev command). Now

configure the TCP/IP settings for this new shared ethernet adapter (ent3). Please note that you have to specify

the interface (en3) and not the adapter (ent3).

$ mktcpip -hostname op710-1-vio -inetaddr 9.156.175.231 -interface en3 \-netmask 255.255.255.0 -gateway 9.156.175.1 -nsrvaddr 9.64.163.21 \-nsrvdomain munich.de.ibm.com

7 Scenario B (two VIO servers)

Create a shared ethernet adapter ent3 with a physical one (ent0) and a virtual one (ent2) with PVID 1:

mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid 1

Configure the TCP/IP settings for the new shared ethernet adapter (ent3):

mktcpip -hostname op710-1-vio -inetaddr 9.156.175.231 -interface en3 \

-netmask 255.255.255.0 -gateway 9.156.175.1 -nsrvaddr 9.64.163.21 \-nsrvdomain munich.de.ibm.com

Client partition commands

No new commands needed just the typical TCP/IP configuration is done on the virtual Ethernet interface

that it is defined in the client partition profile on the HMC
