Notes: 

Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will 

experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. 

Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. 

IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply. 

All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual 

environmental costs and performance characteristics will vary depending on individual customer configurations and conditions.

AIX VUG 2010 

Enhancements to Live Partition Mobility (v2.1.2) 

� Preservation of Virtual Target Device names 

– If the VTD had a user defined name on the source VIOS that name will now be 

recreated on the destination VIOS. 

� Ability to change virtual target device names during a migration 

operation 

$ lsdev -dev vtscsi0 -attr 

attribute value description user_settable 

LogicalUnitAddr 0x8100000000000000 Logical Unit Address False 

aix_tdev hdisk7 Target Device Name False 

client_reserve no Client Reserve True 

mig_name N/A True 

$ chdev -dev vtscsi0 -attr mig_name=test 

vtscsi0 changed 

$ lsdev -dev vtscsi0 -attr 

attribute value description user_settable 

LogicalUnitAddr 0x8100000000000000 Logical Unit Address False 

aix_tdev hdisk7 Target Device Name False 

client_reserve no Client Reserve True 

mig_name test N/A True 


8 

AIX VUG 2010 


� Ability to encrypt traffic between the source and destination 

Mover Service Partition (MSP) 

– A command line interface (CLI) has been added to the VIOS 

to allow the creation of an IPSEC tunneled connection 

between the mover service partitions (MSPs) that are 

responsible for moving a client’s data during a live partition 

mobility event. 

– To enable encryption on the VIOS, the clic.rte package must 

be installed. 


9 

AIX VUG 2010 


� Ability to select network interface to be used for MSP to 

MSP communications 

– If multiple network interfaces are available between a pair of 

Mover Service Partitions, it is now possible through the HMC 

command line to select which IP address the mover will use 

to transport client partition data during a live partition mobility 

event. 

� See HMC man pages for migrlpar for more details 

hscroot@sahmc:~> migrlpar -o m -m p6_570 -t p7_770 --id 5 

--ip 10.56.145.201 -u hscroot –i 

"source_msp_ipaddr=10.0.0.1,dest_msp_ipaddr=10.0.0.4" 


AIX VUG 2010 


� The ability to create non-symmetric VIO server configurations 

$ migrlpar with –mpio flag 

10 

When validating or migrating a partition, use this 

option to specify whether the HMC is required to 

maintain an equivalent multipath I/O (MPIO) 

configuration of the partition's virtual SCSI and 

virtual fibre channel adapters on the destination 

managed system. Valid values are 1 if the HMC is 

required to maintain an equivalent MPIO 

configuration, or 2 if the HMC is not required to 

maintain an equivalent MPIO configuration, but should 

do so if possible. If this option is not specified, 

then this option defaults to the value 1. 


AIX VUG 2010

multiple client partitions simultaneously 

� You could easily boot from and install partitions remotely without having the need 

to swap out physical CD/DVDs or setup Network Installation Manager (NIM) 

server 

� Easier to boot a partition into maintenance mode to repair problems 

� Easier to maintain a complete library of all the software needed for the managed 

system. Various software packages as well as all the necessary software levels 

to support each partition 

� Client partitions could use blank file-backed virtual optical media for backup 

purposes (read/write devices) 

� These file-backed optical devices could then be backed up from on the VIO 

server to other types of media (tape, physical CD/DVD, TSM server, etc.)

$ chrep Change characteristics of a Virtual Media Repository 

$ rmrep Remove a Virtual Media Repository 

Managing Virtual Optical Media 

VIO Command Description 

$ mkvopt Creates a new virtual optical disk in the Virtual Media Repository 

$ lsvopt Displays information about file backed virtual optical devices 

$ chvopt Change the characteristics of a virtual optical media disk within the 

Virtual Media Repository 

$ loadopt Load a virtual optical media disk from the Virtual Media Repository into a 

virtual optical device 

$ unloadopt Remove a virtual optical media disk from a virtual optical device

Create an ISO file from CDROM 

AIX VUG 2010 

Virtual Optical Media 

$ mkvopt -name dvd.AIX_6.1.iso -dev cd0 -ro 

– You choose the name for this file, so make it meaningful 

– Creates an ISO image from the media in /dev/cd0 

After the .iso file is in your /var/vio/VMLibrary directory, run: 

$ mkvdev -fbo -vadapter vhost4 

vtopt0 Available 

– Replace vhost4 with your Virtual SCSI server adapter name. 

– This mkvdev command creates your virtual optical target device. 

$ loadopt -vtd vtopt0 –disk dvd.AIX_6.1.iso 

– The loadopt command loads vtopt0 with your ISO image 

– Replace “dvd.AIX_6.1.iso” with your meaningful filename
