To set Symmetrix arrays to a default of Round Robin, for example, you would now use “esxcli storage nmp satp set –default-psp VMW_PSP_RR –satp VMW_SATP_SYMM”

This means that Microsoft Clustering Service or Veritas Cluster Services are not supported for vCenter 4.x.

Please take this into account when designing mission-critical vCenter deployments.  These customers should be looking at VMware vCenter Server Heartbeat with VMware HA instead of third-party clustering products.

VMware vCenter Server Heartbeat

Basically, use the watch command on the *.vmdk files in the VM datastore.  You can use -n to set a refresh interval and -d to show the change in size between refreshes.  However, the most important information is what base .vmdk file is being written to and when.  This touch timestamp will give you more information on which disk is in progress, which has not yet started, and what is already done.

First, I have recently transitioned over to VMware!  I am now a Senior Consultant in their Federal Professional Services Organization.  Still located here in Minneapolis, and I am currently a resident on-site with a large Federal customer.

Second, I have completed my training class and looking to sit very shortly for the VCP 410 exam.  I have never had an employer previously want to do it since I already knew the material they just figured they didn’t have to pay for the class and test…very excited about this change.

Third, I have now taken over the planning and implementation plans for our vSphere upgrade at my residence.  It was previously assigned to another company and consultant who have sat on it with no progress for months and months.  I am a very busy bee picking this up and mostly starting from scratch but we are moving forward quickly.

I hope to share many findings and challenges I am presented during this upgrade/migration to vSphere and funnel much of it to this site.

I will be in San Francisco May 1st-4th for the VMware TechSummit 2010 and I am really excited to be able to meet some of the talented VMware employees I have worked with and been able to bounce ideas off for so long!  Wish I could attend EMC World and VMworld but those are probably no longer in the cards for me but TechSummit appears to have an unbelievable number of sessions and great technical minds in one place.

Geoff White has created a badly needed tool here, Perfmon worked but was very time consuming.  Especially with those days or weeks of ESXTOP statistic files.

Extract and use the README.  For Windows, extract all files, navigate to the esxplot.exe in the Bin directory and you are off and running!

Geoff White now has a full project site with all information and releases.  Click here

Labs.vmware.com has now gone live and hosting ESXPlot as well.  Click here

VIOPS has a good document on how to cluster the vCenter services on MSCS.  Things have changed slightly from 2.5 and though most of the steps will be old news for some, there are a couple changes so be sure to review before proceeding with your Install/Upgrade projects.  It does have a nice section on upgrading existing clusters as well.

Get the document here.

One special note I would point out is running the “jointool.bat” for replicating roles at the end of your cluster config.

Please see the KB here.

I know there are plenty that will disagree and have found ways of doing it, but within our environments for our MSCS clusters using Physical mode, we disable DRS and only Cold vMotion once the resources of the cluster have been moved off the Node and the VM is Powered Off.

*Update*  An official Hardening Guide for vSphere 4 has been released http://communities.vmware.com/docs/DOC-12306

This allows you to check the disk status for options such as Fault Tolerance or Microsoft Cluster Services.  The disks must be in an Eagerzerothick format for these options to work.
