While attempting to use Host Profiles with IBM hardware, you may receive an error when trying to apply a host profile "An error has occurred".
This error is actually due to the IMM – “InBand” communications device presenting itself as an Ethernet over USB device to the operating system as a legit network card.
In VMware it presents as vusb0 as per the pic below:
In this particular case it created issues with the Host profiles (the VMware Host profiles would partially implement and then error out with totally meaningless errors which were quite hard to troubleshoot).
It also swaps the PCI addressing order around during / after the install phase, so when we selected the first PCI addressed NIC to be the Service Console Uplink during the intial install, after the reboot at end of ESX install the vusb swaps itself in as the primary SC NIC (based on PCI address). Though this doesnt always happen, it depends on the hardware model. An example is on HS22 blades the host profile issue occurs but the PCI swapping does not occur.
We resolved both issues by setting the following value in the IMM settings in the BIOS:
Commands on USB Interface = Disabled |

The different versions of vSphere are Standard, Advanced, Enterprise and Enterprise Plus. If you are an existing VI3 customer covered by SnS and licensed for VI3 Enterprise you will be transitioned to vSphere Enterprise Edition.
If you then want to take advantage of the distributed network switch, use a third party distributed switch or host profiles you will have to upgrade to Enterprise Plus.
The different versions have different featuresets and limits. The table below identifies which feature is included in what edition.

The VMware Certification website has released the information around certification and paths to VCP on vSphere. This was leaked from the beta program by some other bloggers on the vSphere launch date but is now confirmed and not NDA.
There are multiple options and paths depending on where you sit with your current education and certification path. You may be a VCP on 2.x or you may be a VCP on VI3 or you may have sat a course. Each of these requires a slightly different path so read carefully. The exam will be released in Beta 30 days after the GA date. So this means it should be available around the 21st of June 2009. The courses will be released shortly after.
Basically, the short of it is : - If you are already a VCP on VI3 (most of you) then you really only need to sit the VCP on vSphere 4 Exam and it must be done before the 31st of December 2009, after that date you will need to sit the "What's New" class in order to upgrade.
- If you are a VCP on ESX 2.x, then you can sit the VI3 exam. Pass that and then you can sit the VCP on vSphere 4 Exam, once again this option is only available until the 31st of December 2009. After that date you would need to sit the "What's New" class in order to upgrade
- If you are NOT VCP on anything, then you do need to sit the VMware vSphere "Install, Configure Manage Course" or the "VMware vSphere 4: Fast Track" class and then sit the VCP on vSphere 4 Exam. Both of these courses are not currently available and not expected until after late June 2009.
- If you are not a VCP but have attended one of the VI3 courses (Install & Configure; Deploy Secure and Analyze or fast track) then you can take the VI3 exam, and the the VCP on vSphere 4 exam OR sit the vSphere 4 "What's New" and take the VCP on vSphere 4 Exam.
The full details of the associated requirements and course materials can be found at the VMware Certification Website. |
