vRealize Operations 6 root password

vRealize Operations 6 is major change from 5.x version. It is an architecture change. The root password is no longer set as part of installation. Quoting the manual “After you install vRealize Operations Manager, you secure the console of each node in the cluster by logging in for the first time. ”

To set it, you have to go to the console (I have not figured out how to do it on Windows as to me it’s easier to use appliance). So launch the console. I use the vCenter C# sharp client below.

10 root password

Press Alt+F1 to get the login prompt. Type root. The default password is blank, so you simply press Enter key. It will prompt you to change password. Type the new password. It checks for password complexity.

Once done, you get the screen below.

11 root password - no dictionary

That’s all!

VMware ASEAN Lab: hands-on day

December has always been a time where I upgrade the VMware ASEAN lab. The lab has been a critical tool in my roles as an SE. We use it to learn products, see how they fit together, do demo, and do POC.

We’ve been working to upgrade the lab. Folks like Rayne and Iskandar have been great in tidying up all the cables. Now that the physical layer is taken care off, we are now ready to work on the software layer.

When we architect-ed the lab, I wanted to make sure we did not miss anything. I find that thinking in terms of layers help me to ensure nothing is missed. The first diagram shows the components by layer.

1 Function by layer

Now that I have everything, I need to think in terms of their relationships. I know a lot of things are connected and dependant on vCenter. So I created the diagram below. In this diagram, I also add that there are 2 layers of network, as there are VMs that will be in the virtual network. NSX will be used to separate them from the physical network.

2 Relationships in a single vCenter

Now, the above is good, but does not show the fact that I need to have Production DC and DR DC. SRM also requires 2 vCenter Servers. So I created the diagram below to show it. I had to simplify some connections, such as SSO and AD, as practically all VMs talk to them. I’m excluding EUC (Horizon, Mirage, Air Watch) as it’s separately managed by our EUC SE.

3 Relationships in 2 vCenter with DR

The next thing is to map them into the physical ESXi and storage that I have. We have limited hardware, so there will be adjustment. For example, EUC and SDDC are sharing vCenter. It is certainly not ideal, but it gives us real experience on what happens when you combine solutions that are best separated.

My plan is to use SRM to protect vRealize Suite. Perhaps not all components due to limited hardware.

4 VM and Clusters

The next diagram shows the physical mapping in more details. I’ve listed the datastores this time around. I’m also showing that there is 1 SSO, as it’s more practical this way. I find that being able to manage across vCenter to be useful.

5 Physical grouping

Hope you find it useful. Feel free to replicate it. There is a lot more technical information, as I document most of them in Google Site.

Email tips: deleting all emails without actually deleting them

In a previous post, I shared about the “secondary inbox” concept. Essentially, it cuts down my primary inbox significantly. The diagram below shows that the “Not for me” becomes a great filter for my Inbox.

However, they do not solve another problem, which is some emails require follow up. That’s the problem, the word “some”. Not of all them do, so I need to delete those who do not require follow up. All I want is to press delete from my mobile phone, as I’m mobile most of the time. I do not want to move email to another folder. I just want to press delete. It’s a lot more convenient!

So I delete any emails that do not require follow up on my part. If it’s for my reference, I deleted it. If an email maybe useful in future, I deleted it. If an email is important but I do not need to act on it, I deleted it. I just base on 1 question: Do I need to act on it?

Now, you notice in the diagram above, I’ve put a Recycle icon in the Trash box. This is because it’s no longer my trash can. From time to time, normally 1x a month, I move everything in the Trash into an Archived folder. As a result, I never actually delete any emails.
