IVM的管理方式与HMC不同
1. 整机装VIO(IVM集成在VIO内), 此时所有的的硬件资源（CPU，内存，IO设备）都属于VIO
2. VIO安装完后，用浏览器访问IVM可以进一步划分出多个分区，但IO资源只能共享，不能独占

谢谢.谢谢.
我再试试. 明天带VIOS光盘过去折腾.
BTW
今天JS21安装5304 引导起来了.认到CPU这步了.不往下走.
JS21与AMM的FW都是最新的.
安装5307的没问题.在想是不是客户刻录的5304光盘有问题了.

Boot problem resolution


Depending on the boot device, a checkpoint may be displayed on the console for an extended period of time while the boot image is retrieved from the device.
This is particularly true for CD and network boot attempts. When booting from a CD, watch for a blinking activity LED on the CD or DVD drive.
A blinking activity LED indicates that the loading of either the boot image, or additional information required by the operating system being booted, is still in progress.
If the checkpoint is displayed for an extended period of time and the CD- or DVD-drive activity LED is not blinking, there might be a problem loading the boot image from the device.
Note: For network boot attempts, if the system is not connected to an active network, or if there is no server configured to respond to the system’s boot request, the system will still attempt to boot. Because time-out durations are necessarily long to accommodate retries, the system may appear to be hung.
If you suspect a problem loading the boot image, complete the following steps:

001 Make sure that your boot list is correct.
1. From the BladeCenter management-module Web interface, display the boot sequences for the blade servers in your BladeCenter unit: Blade Tasks → Configuration → Boot Sequence.
2. Find your blade server on the list that is displayed and make sure that the device from which you are attempting to boot is the first device in the boot sequence. If it is not, select your blade server from the list of servers and modify the boot sequence. Cycle power on your blade server to retry the boot. Note: If Network is selected, the blade server will try to boot from both Ethernet ports on the system board.
3. If this boot attempt fails, do the following:
a. If you are attempting to boot from the network, go to Step
002.
b. If you are attempting to boot from the CD or DVD drive, go to Step
003.
c. If you are attempting to boot from a hard disk drive, go to Step
004.
002
If you are attempting to boot from the network:
1. Make sure that the network cabling to the BladeCenter network switch is correct.
2. Check with the network administrator to make sure that the network is up.
3. Verify that the blade server for your system is running and configured to respond to your system.
4. Turn the blade server power off; then, turn it on and retry the boot operation.
5. If the boot still fails, replace the system-board and chassis assembly.

003 If you are attempting to boot from the CD or DVD drive:
1. From the BladeCenter management-module Web interface, make sure that the media tray is assigned to your blade server: Blade Tasks → Remote Control.
2. Turn the blade server power off; then, turn it on and retry the boot operation.

3. If the boot fails, try a known-good bootable CD.
4. If possible, try to boot another blade server in the BladeCenter unit to verify that the CD or DVD drive is functional. v If the CD boots on the second server, replace the system-board and chassis assembly in the JS21 blade server you were originally trying to boot. v If the CD fails on the second server, replace the CD or DVD drive in the media tray.
5. If replacing the CD or DVD drive does not resolve the problem, replace the media tray.
6. If booting on all servers fails using the new media tray, replace the following in the BladeCenter unit: v Management module v Midplane
004 If you are attempting to boot from a hard disk drive.

1. Verify that the hard disk drive is installed. If you are trying to boot from the second hard disk drive, verify that the second hard disk drive is installed.
2. Select the CD or DVD drive as the boot device.
3. Go to “Performing the checkout procedure” on page 89.
4. Reload the operating system onto the hard disk drive if boot attempts from that disk continue to fail.
5. Replace the suspect hard disk drive if you are not able to load the operating system.
6. Replace the system-board and chassis assembly; then, retry loading the operating system

We configured JS21 blades for one banking customer for their SAP development and quelity assurance enviroment using the APV and IVM features to create 3 partitions (one the VIOS and other two as VIO Clients). LPARs are abooting from SAN based disks virtualized throught the VIOS Server. We have even use the virtual ethernet adapters in order to create the NFS mount points to configure the transport system.

Up to date, everything is running at very good performance.

Documenting the AIX VIO Server VSCSI Allocations using a Database

Introduction
In the Red Paper - IBM System p Advanced POWER Virtualization Best Practices, the current best practice is to record them in a spreadsheet, I could agree with that if the process to update the spreadsheet would be an automatic one with little or no supervision.

I have written a perl script to help me manage the actualization process, it dumps the information to a MySQL database and currently supports only VIOS 1.5.1 but it is easily modifiable to support previous versions.

[Edit section] Language and Platform
The script runs fine on perl v5.8.5, requires the DBD::MySQL and a MySQL database

[Edit section] Pre-requisites
The script requires passwordless public/private ssh login authentication to the HMCs and VIO servers.
The LPAR names need to match the hostname and be resolvable and accessible from the box documenting the VIO Maps.
A symbolic link from /usr/bin/ioscli needs to be created to point to /usr/ios/cli/ioscli.
I have an Expect based version for those who still need telnet access to the VIO server.
I can work on one to access the VIO Server using the Vitrual TTY.
[Edit section] Version
1.0

换一个BLADECENTER的箱子就可以安装AIX5304.
可能是BLADECENTER H的光驱兼容性问题.

Hello,
I am completely new to virtualization and any help would be greatly appreciated . I have a JS21 (type 8844); the blade was shipped without VIOS installation media, and I don't quite understand if this means the following:
the APV feature was not activated;
I cannot exploit the virtualization features of the JS21 blade.
If that is the case, how can I get the VIOS media and activate the APV?

Thank you in advance for your help.

migration lpar to vio -  permalink
October 17th, 2007

--------------------------------------------------------------------------------


Hi guys
i must migrate 3 test was lpar under vio , and virtualize both lan and san . with the minimum downtime possible .
no questions about the lan , the san and the external vg are
my first preoccupation , rootvg will be re-created from a mksyb or cloning and moving disk by alt_disk_install .
extra vio i've sdd installed on ds8000 , and ill'go to sddpcm ( on both vio ) with mpio .
for you i can simply varyoffvg , umount all external fs shutdown lpar , power on the vio client_lpar , restore the mksysb , and after storage people mask the lun to vio , mapping this device to client_lpar and import the vg from disks ??!

Backup VIO environment - September 12th, 2007

--------------------------------------------------------------------------------


Normaly do this
============
Backup each system using mksysb once a week (to nim server ,tape or DVD )
backup all other filesystem on the systems using backup tools or scripts
backup vios to ( nim or dvd ) backupios in script
backup all system information on VIO in a script colecting the following stuff
netstat -state
netstat -routinfo
lspv
lsvg
lsvg -lv rootvg
lsdev -type adapter
lsmap -all
lsmap -all -net
this all go's in to a file on my nim server
HMC backups

I also have automaated documentation that runs on each system every day to collect system information and changes to the system in to HTML formated docs.
This is good for security and looking back when problems come up

Abstract
This IBM Redpaper provides best practices for planning, installing, maintaining, and operating the functions available using the Advanced POWER Virtualization feature on IBM System p5 servers.

The Advanced POWER Virtualization feature is a combination of hardware and software that supports and manages the virtual I/O environment on IBM POWER5 and POWER5+ processor-based systems. The main technologies are:




Virtual Ethernet

Shared Ethernet Adapter

Virtual SCSI server

Micro-Partitioning



This Redpaper can be read from start to finish, but it is meant to be read as a notebook where you access the topics that pertain best to you. This paper begins where Advanced POWER Virtualization on IBM System p5, SG24-7940, ends by adding additional samples and scenarios harvested by a select team that works at client and outsourcing sites, running both small and large installations. The experiences contained within are select best practices from real-life experience.

A working understanding of the Advanced POWER Virtualization feature and logical partitioning and IBM AIX 5L is required, as well as a basic understanding of network and VLAN tagging.

Note: Advanced POWER Virtualization is now a set of editions available under the PowerVM brand. This paper applies applies to the basic tecnologies that are common with the new and old naming.
