The I/O scheduler used for the OS disks might need to be different if using VMDKS. Instead of using CFQ, use deadline or noop elevators. Performance varies and must be tested.

Re: Need a CMDB recommendation
Discovery and Dependency Mapping solutions can aid organizations in maintaining an accurate and up-to-date view of the dependencies, so as to understand service relationships. The alternative manual approach can be highly labor intensive with time delays for updates and, again, run the risk of drift between the perceived state of the infrastructure in the CMDB and the actual state of the infrastructure in the production environment.

If your standard image installation is making ESXi up, you can try adaptec vibs installing additionally post ESXi installation and see the behavior.

Re: VM get stuck at 95% of the Power On virtual machine stage
This may be a symptom of another problem.
If the host has a hardware RAID controller, see if the batteries are still good. Otherwise, a power failure often corrupts it and has to rebuild.

Re: Questions about VCP6-DCV
Hi, I have been using VMware Workstation for sometime and vSphere 6.7 for around 2 months.
I am certainly not new to Virtualisation as I am a MS Certified Hyper V admin.
But I an fairly new to the world of vSphere.
I don't want to be wasting my money on courses that don't prove anything apart from the fact that I have attended a course that I could have done myself and save myself from someone else reading out the book to me. Especially if the exams expire every 2 years and they cost on average a months salary!! That is ridiculous and will make me think twice about becoming certified.
I cant find any exam for vSphere 6.7. The only one that I can locate is this on VMware Certified Professional 6.5 - Data Center Virtualization (VCP6.5-DCV)
It says the path is :
1. Gain experience with vSphere 6.5
2. Attend one of the required training courses
3. Pass One of the Foundation exams
4. Pass the VMware Certified Professional 6.5 – Data Center Virtualization exam
Thanks

Re: Questions about VCP6-DCV
Hi,
Exams expire every 2 years yes but it doesn't cost a month's salary... I don't anyone who works for 300$ per month.
If you want, you can try gaining experience by using the HOLs:VMware Learning Platform
And if you want to gain the certification it's mandatory to take the course, there is no other way.
So, it's up to you if you want to take it or not.

Re: ESXi 6.5 stuck on Starting service vmtoolsd
This problem could be potentially caused by VT-d enabled in the bios with Adaptec controllers. Try disabling this first (though, I believe this issue was fixed in newer driver versions, it wouldn't hurt to rule this out if you don't require hardware pass-though).
If you are still getting the same issue with only the driver installed (not vmware-esx-provider-arcconf.vib or vmware-esx-provider-arc-cim-provider.vib as they are not required for accessing the data, only management of the controller / array), then you could potentially be having a more serious problem with the array.
Controller hangs / continuously scrolling "Host adapter abort requests" can also occur if the array contains a "badly behaving drive" when ESXi attempts to load the data store. By "badly behaving drive", I mean specifically the drive is not responding to commands from the controller and the controller is (for whatever reason) unable to drop the drive from the array.
If you are using a 5-series or 6-series controller without a SAS expander, you can enable hard drive activity lights from within the controller's bios settings during boot up of the server (CTRL-A). It might be possible to identify the "badly behaving drive" by observing the hard drive activity lights (I believe they are green LEDs on the controller). The bad drive will sometimes illuminate the activity light continuously while others with flash as the drives are accessed.
If you have a 7-series or newer controller, I believe Adaptec had removed the activity LEDs from these controllers, so you would not be able to identify a drive in this fashion. You would need some sort of HDD backplane which would illuminate a drive activity LED when the drive is being accessed by the controller.
If this is the case *AND* if you have some remaining redundancy within your array (eg a RAID-6 array with one failed disk and *ALL* remaining disks are working flawlessly with no undiscovered bad blocks), you could try disconnecting the "badly behaving" drive. *** USE CAUTION *** as if this does not solve the problem, you cannot simply re-add the disk to restore the previously level of redundancy without performing a rebuild. If you have multiple failed/failing disks, you could experience a total loss of your array data by doing this. Proceed at your own risk.
If the above is not the case, you could try booting the server using an Adaptec supported Linux distro or Windows and see if the OS reports similar abort commands. Linux might provide more detailed information as to what is going on with the controller/array. If you are successful in booting Linux or Windows without having the system lock up, you could attempt to download the controller's firmware logs by creating a "support archive" and reviewing those logs. The "support archive" logs often have more detail as to what his happening within the controller/array. ***USE CAUTION*** to NOT write any data to the array while in Windows or Linux as it could permanently damage the VMFS filesystem. Proceed at your own risk.
*** Additional Caution ***
If you have a 5-series or 6-series controller in RAID-6 with >2TB disks, DO NOT attempt to rebuild the array. There is an undocumented firmware bug in these controllers that *WILL* corrupt your data if you attempt a RAID-6 rebuild with >2TB disks while there is background write activity happening on the array (such as VMs running). The issue may also apply to RAID-5 arrays, but has not been confirmed as far as I'm aware. The same applies to older firmware versions of 7-series and 8-series controllers, though newer firmware resolved this issue for these controllers.
*** Additional Caution #2 ***
Don't change the firmware of the controller while the array is in a degraded state. It is recommended to first get the array up to "Optimal" state before changing firmware levels on the controller.

Re: Horizon View Machine local network access
It is not supported to install the horizon agent on a domain controller. The agent has a pre-check to see if the server is a domain controller.
Horizon is a not a VPN therefore you're not going to be able to tunnel traffic between the client and agent. You need a VPN solution in your case. As for a vpn solution, I'm not going to give you the best answer. Only thing I can suggest is you may be able to accomplish a connection using Hamachi (vpn.net) if you cannot open up any more external connections.

Re: VMWare horizon ThinPrint, Local Driver
Here is the workflow for printing using thinprint. As you can see, the printer driver used is the one on the horizon client. If I understand you correct, what you need to do is install the printer on the horizon desktop using group policy, UEM, or another method with the drive you want. If your using a Windows print server, you load the client version of the print driver on the server.

so, i see your logic. The Cert should be fine.

Re: ESXi 6.5 stuck on Starting service vmtoolsd
Thank you everybody for the great support. I'm so impressed to get so much attention on a Saturday!!
So long story short: is fixed
All I had to do was to removed the faulty disk from the RAID5 and now it boots properly. Note this was part of a data array and not the boot one ESXi uses.
On one side I'm happy things eventually work because, I don't know you, but after hours trying to make things working I get bored and lose interest... so when it finally works and I can relax on the sofa it does come with a sense of achievement :-D
On the other side (the predominant right now) I just want to say "what the heck!" A RAID controller is made to provide resiliency not to introduce extra issues. I don't have major concerns if now and again one disk fails but why would the OS be affected by this only God and perhaps not even the Adaptec engineers know.
Final note: The last installation/upgrade I made was with the adaptec controllers drivers only (no CIM provider or ARCCONF) this is good enough for my needs as I just need to see the status of the array from Hardware/Storage, however after a quick verification under Manage/Packages if I filter by Adaptec and this is what I can see:

Re: vcenter vcpu calculator
Whether an infrastructure is correctly dimensioned and whether it needs to be expanded and if so, by how much physical capacity, depends on many individual details. In addition, the workload is very different in most infrastructures. Therefore, there is no blanket statement or a simple vCPU calculator. At the latest when CPU, memory or storage is used to 70% or more, you know for sure that you have to expand. But performance problems can occur much earlier.
If you look only from the perspective of CPU performance, you should pay attention to the physical core to vCPU ratio. As a best practice it has been proven that a pCore : vCPU ratio of 1:1 - 1:3 works well with most workloads and from 1:5 it becomes bad for some workloads. However, there are also infrastructures where 1:2 already leads to performance problems and infrastructures that hardly notice performance bottlenecks with 1:10.
So I would recommend you either do the math yourself and calculate the ratio and check the CPU Ready values of all hosts over a longer period of time or what might be easier for you: Use vRealize Operations Manager and show your boss the Capacity Dashboards.
