ESXi 6.5 U1 Host Client Login Issue

Today I did a fresh installation of ESXi 6.5 U1. During the installation, set up the root password.

After everything is working with IP address assigned, DNS and gateway, we started to try to access using the Host Client using IE 11.

Encounter this message "cannot complete login due to an incorrect user name or password". Thought that might have entered the wrong password. Type in a notepad and copy and paste. Same error message encountered on both servers.

Did some search but never encounter anyone having the same issue other than old post found on ESXi 6.0 with the old vSphere Client. Decide to try out one of the method.

Head right down to both server and use the DCUI and select Change Password option. Use back the same password.  Walah! Host Client works now.

Very strange behaviour. Apparently during installation seems like the host client didnt register the password.

Hope this help for those encountering the same issue.

VMware ROBO License

Recently there was some discussion over licensing in Facebook vExpert group.

One of the users questioned about licensing 3 hosts, each placed at one location. He wants to be able to do a snapshot and monitor the health of the ESXi host. He intends to add a fourth host in future. He was also told by the account executive that vSphere Essential cannot meet this requirement.

Let me explain some of the information which might be not clear enough.

vSphere Essential and Essential Plus kit is a bundle that comes with vCenter Server Essential (which is not available for sale) and vSphere Essential/Essential Plus licensing. ]vCenter Server Essential can only manage up to three ESXi servers. The vSphere Essential kit allows you to license up to 3 hosts or 6 CPUs whichever come first. But you cannot license more than 3 hosts even if each only has 1 CPU. This is because vCenter Essential can only manage up to 3 ESXi hosts. Also, the licensing would not allow you to manage using a vCenter Server Standard edition.

Check out the site here for comparison including ROBO licenses.

vSphere ROBO office comes in packs of 25 VMs. It has 2 editions namely, Standard and Advanced. Just check out the comparison above. You might find 25 VMs is quite a number, however, you are allowed to split the license to a smaller amount via the license portal. Meaning, you can deploy the vSphere ROBO license to multiple remote sites up to a maximum of 25 VMs per site which is declared as ROBO.

In this way, customers do not need to spend buying vSphere Essential/Essential plus which is the cheapest kit available, for a remote site. This helps many customers save on cost with vSphere ROBO licensing.

Hope this explains and give you a better understand how vSphere ROBO licensing is applicable and how to use it.

VMware vSAN 2017 Specialist

There are two specialist certifications release by VMware, namely vRealize Operations and vSAN.

Recently I took the attempt for vSAN Specialist Exam. Before we go into it, let see what is the requirement to take this exam.

You need to have a valid VCP 6.x on any track. No course requirement but the vSAN Deploy and Manage is recommended.

There is only a Digital Badge when you passed the exam and there is no certification for this exam.  The exam code is 2VB-601: VMware Specialist: vSAN 6.x Exam.

Do check out the exam guide. However, the guide does not indicate the exam time and the number of questions. Total questions were 60 from what I encounter and the time is similar to VCP about 240 mins. Cost for me is SGD363 (this might differ for other countries).

You are required to know everyone on vSAN from 6.0 to the latest now 6.6. Everything in these versions will be tested. It will be good to understand the concept and fundamentals of the technology as well all the features that have released since.

Personally, I felt that the exam is not too easy or was it too tough to fail. It really targets at someone who has an understanding of vSAN to a certain level. If you are merely just reading feature functions and not knowing how vSAN really works, then this exam will be tough for you.

Once you passed, you will receive a notice the very next day with your Digital Badge like mine.

Good luck to those attempting.
