I have a mixed ESX cluster at home. One box is running ESX 3.5 the other box is running ESX 4.0. When I tried to enable HA on this cluster I got the following error:
The ESX 3.5 host has a second Service Console port on the Storage (iSCSI) lan. The ESX 4.0 host doesn’t need this so this is why the ESX 4.0 host got this error.
To solve this issue I created a second Service Console Port on my ESX4.0 server.
Now I was able to enable HA on Cluster.
If you add an ESX 3.5 host to your vSphere Cluster,there is a change you’ll get this warning:
The solution is simple, you need the “old” license server running in your network. So download the “old” license server from http://vmware.com/download/vi/drivers_tools.html
Install the License Server for ESX 3.5 on different server than your vCenter box. I tried installing it on the same box, but it ended with a failed startup of the License server services. The installation is straight forward (read next, next, add license file, next and finish).
After the installation open the vCenter Service Settings option.
And enter the address of your license server and press ok.
Now it’s possible to add the ESX 3.5 host to your cluster.
The Enhanced vmxnet adapter was already available in ESX 3.5 (see KB1001805). The support for this adapter is a lot better since Update 4 is released. Now you can also add the Enhanced vmxnet adapter to a Windows Server 2003 VM, without the workaround mentioned in KB1007195.
Some info about the Enhanced vmxnet from KB1001805:
Enhanced vmxnet — The enhanced vmxnet adapter is based on the vmxnet adapter but provides some high-performance features commonly used on modern networks, such as jumbo frames. This virtual network adapter is the current state-of-the-art device in virtual network adapter performance, but it is available only for some guest operating systems on ESX Server 3.5. This network adapter will become available for additional guest operating systems in the future.
Enhanced VMXNET is supported only for a limited set of guest operating systems:
- 32/64-bit versions of Microsoft Windows 2003 (Enterprise and Datacenter Editions). You can use enhanced vmxnet adapters with other versions of the Microsoft Windows 2003 operating system, but a workaround is required to enable the option in the VI Client. See http://kb.vmware.com/kb/1007195. Since Update 4, you can add the Enhanced vmxnet via the VIC.
- 32/64-bit versions Red Hat Enterprise Linux 5.0
- 32/64-bit versions SUSE Linux Enterprise Server 10
- 64-bit versions Red Hat Enterprise Linux 4.0
And a warning:
Migrating virtual machines that use enhanced vmxnet. Enhanced vmxnet is new with ESX Server 3.5. Virtual machines configured to have enhanced vmxnet adapters cannot migrate to older ESX Server hosts, even though virtual machines can usually migrate freely between ESX Server 3.0 and ESX Server 3.0.1.
If you must migrate a virtual machine between newer and older hosts,don’t choose enhanced vmxnet but instead one of the older adapter types. Flexible or e1000 are offered whenever enhanced vmxnet is offered.
Bouke released a new version of his RemoveHBA.sh script. The new version is also compatible with ESX 3.5 update 4:
This new removehba script removes the HBA drivers from the ESX 3.x ISO. Added support for 3.5 U1, U2, U3 & U4. VMware changed some files where the drivers were in and the script is taking care of that now also.
Download the script here: http://www.jume.nl
VMware ESX 3.5 Update 4 has been released. You can find the download and release notes here:
Not all combinations of VirtualCenter and ESX Server versions are supported and not all of these highlighted features are available unless you are using VirtualCenter 2.5 Update 4 with ESX Server 3.5 Update 4. See the ESX Server, VirtualCenter, and VMware Infrastructure Client Compatibility Matrixes for more information on compatibility.

Paul Shannon heeft weer een super document gemaakt over het maken van een Unattended Installatie CD voor VMWare ESX. In de tijd van ESX 2.5.x heb ik ook eens zo’n CD gemaakt door de volgende guide te gebruiken: http://www.vmprofessional.com/index.php?content=kickstart_2. Helaas werkte deze guide niet meer met ESX 3.5. Ik ben dus erg blij met het document van Paul. Thanks Paul!
Paul schrijft het volgende op zijn blog:
I had a customer that had a requirement to backup the ESX Service Console settings and wanted to know the best files to backup. I suggested that it may be more prudent to create unattended installation media to make restores more seamless. This took a turn and I was asked to make a single CD that was capable of restoring any one of the 11 ESX hosts in the clusters. With a lot of reading and a lot of testing this was achieved and this document explains how I did it.

Hugo Peeters heeft zijn Powershell scripts voor het vullen van Custom Fields in vCenter gepost:
I already showed you how to do this, but I have now added an IF-statement so that only changes are updated (equal values are not overwritten). And I have added Julian Wood’s correction. Add-VMSnapshotCount.ps1
Total Snapshot Size
The number of snapshots is quite inetresting, but even more interesting, is the total size of the delta files all snapshots are occupying. They might be eating up all your precious SAN space. Plus, reverting to or committing a large snapshot is tricky. Add-VMSnapshotSize.ps1
Host Hardware Model
Want to see what models of hardware you are using in your datacenter? You could look at the summary tab of each host. Or run this script to add the info to the every Hosts tab in the VI Client. Select your Datacenter, select the Hosts tab and enjoy! Add-VMHostModel.ps1
Host ESX Version
Did you update all your ESX Servers to the latest version? Check it quickly using this script. Add-VMHostVersion.ps1
Host LUN Count
Last but certainly not least: are you sure every datastore you are using is available to all your ESX Servers? It is visible at a glance when you add the LUN Count to your VI Client! Add-VMHostLUNCount.ps1
