See the links above for more info...
So the only change has been going from Server 2003 SP2 32 bit OS that Virtual Center 2.5 was running on (in a virtual machine) to Server 2008 SP1 64 bit Enterprise and vCenter 4 update 1 (in a virtual machine). Of course it does a database upgrade during the install so maybe it is talking to the database in a more optimized way. But you sure are not left waiting for results anymore.
The other important user friendly part is the search feature, so now you can find anything without drilling down into places.
Great Job VMware!
VMware Thin Provisioning Performance White Paper
Tuesday, December 29, 2009
Our virtual center and SQL 2005 servers are both virtual, and our goal was to follow the strong suggestion from VMware: Future releases of VMware vCenter Server might not support installation on 32-bit Windows operating systems. We also wanted it to be the license server for the ESX 3.5 servers as well until we get migrated.
The vSphere Upgrade Guide for Update 1 had some instructions for doing this but I'll walk you through the steps I took below which might help. I had already prepared items in a folder I would need during the rebuild of the new 64bit vCenter.
You will need:
SSL files from old virtual center:
C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\SSL
SSL files go here on new 64bit server:
C:\Users\All Users\VMware\VMware VirtualCenter\SSL
Sysprep files Old:
C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\sysprep
Sysprep files new:
C:\Users\All Users\VMware\VMware VirtualCenter\sysprep
\Program Files\VMware\VMware License Server\Licenses
35 license server files new:
\Program Files (x86)\VMware\VMware License Server\Licenses
- rename current virtual center 2.5
- deployed new Server 2008 64 Enterprise SP1 vm
- removed my DRS rule to keep the SQL and old virtual center together
- made a note of the ESX server new vcenter vm is on
- shutdown old vcenter, remove from AD
- configure new vCenter 64 bit OS, Join domain
- copy SSL files (make the directory that doesn't exist yet--see above)
- install sql native client (64 bit version)
- setup ODBC (remember to use 32 DSN by running c:\Windows\SysWOW64\odbcad32.exe and select SQL Native driver)
- Perform the vcenter install
- copy sysprep files, check everything out (agent updates take place on the servers)
- Install the virtual center 2.5 update 5 license server only and point to your license files
- set vCenter to be the license server for ESX 3.5 servers (under vCenter Server Settings)
- and that was about it...still need to update the other components (update manager, etc)

NTPRO.NIL is reporting that VMware has extended the deadline to Jan 31, 2010 for current VCP 3 holders to pass the VCP 4 certification without taking the What's New Class. This apparently is due to a rush of people not being able to book the exams.
See the link for more details.

I hope you will enjoy some quality time with Family and friends during this holiday season. I encourage you to remember the true meaning and purpose of this holiday, honoring the birth of Jesus Christ, our Savior, our Lord. I hope you have a relationship with GOD and will spend time in prayer and church celebrating the salvation and thanks we owe Jesus for dying for our sins so that we may have everlasting life and forgiveness of our sins.
Merry Christmas to you all!
Fortunately we don't all have to be programmers and tools have come along (PowerGui) and (EcoShell) which help us learn and do some amazing powershell stuff. First, head over to The Virtualization EcoShell Initiative to download and get this tool. Videos are available at the bottom of the screen showing you the power of the product. An advanced training video I learned about from ntpro.nil is located on Vizioncore's site.
You will love the vDiagram (generate Visio reports of your environment) and vReporting (Generate html reports) features I am sure!

Please see this original post for information on a vSphere 4 storage bug that appears to be getting several people.
It deals with removing a LUN from the server…and the order you perform the process. The proper sequence is:
- In the vSphere client, vacate the VMs from the datastore being removed (migrate or Storage vMotion)
- In the vSphere client, remove the Datastore
- In the vSphere client, remove the storage device
- Only then, in your array management tool remove the LUN from the host.
- In the vSphere client, rescan the bus.

1-day Manage Scalability: covers the specific features of vSphere related to scalability, such as Host Profiles, Distributed Power Management, and vCenter Linked Mode

I donated $25 I thought it was so good. Very customizable by by easy commenting or uncommenting sections in the code.
I scheduled it in task scheduler with these commands:
in the arguments section: -PSConsoleFile "C:\Program Files\VMware\Infrastructure\VIToolkitForWindows\vim.psc1" & C:\Scripts\dailyreport.ps1 vcenter
vcenter would be the name of our virtual center server.
I came across this little tip from this link:
Apparently vSphere 4 will show you stats of your Vmotion performance.
Just do: tail –f /var/log/vmkernel
Article also explores does having a lot of bandwidth really help! Good read!
We had a problem with a template..not being able to turn it on...we would get a file locked error.
Not sure how someone accomplished this but they had used the template VMDK file in a deployed virtual machine. How did I find this out? Using the command shown below, which looks through all the virtual machine config files to find if any other machines were using the file. xpsp2basethin.vmdk was the file in use.
[root@esx3srv0301ph xpsp2base]# egrep -i xpsp2basethin.vmdk /vmfs/volumes/*/*/*.vmx
/vmfs/volumes/499f22e3-2239bc87-25f0-001a6459e0f8/vpcuniversity2/vpcuniversity2.vmx:scsi0:0.fileName = "/vmfs/volumes/499f2335-cd135fea-a4dd-001a6459e0f8/xpsp2base/xpsp2basethin.vmdk"
/vmfs/volumes/499f2335-cd135fea-a4dd-001a6459e0f8/xpsp2base/xpsp2base.vmx:scsi0:0.fileName = "xpsp2basethin.vmdk"
/vmfs/volumes/hdsvpc3a/vpcuniversity2/vpcuniversity2.vmx:scsi0:0.fileName = "/vmfs/volumes/499f2335-cd135fea-a4dd-001a6459e0f8/xpsp2base/xpsp2basethin.vmdk"
/vmfs/volumes/hdsvpc6a/xpsp2base/xpsp2base.vmx:scsi0:0.fileName = "xpsp2basethin.vmdk"

I really enjoy sharing the information I learn with all of you. And I really appreciate all the other bloggers out there passing on their knowledge and experience. It's all about giving back to the community and helping others find how important the virtualization technology is to their careers and companies.
Unfortunately, I have been extremely busy at work and studying for the VPC 4 exam. Nothing like an economic crisis to get virtual as the first choice for new servers! My work also put in new security software that blocks many blog sites while others it allows..which has really been a pain. Then I remembered I could post via email..so I am back online again.
Thanks for visiting my blog. Stay tuned..we have a lot of catching up to do!!
