I ran into an error the other day, when updating an IBM based vSphere 6.0 environment using Update Manager, and I want to share my solution with you and myself, so I do not need to find it the next time I run into it.
ERROR: The host returns esxupdate error code:15. The package manager transactions is not successful. Check the update Manager log files and esxupdate.log files for more details.
Are you looking to Upgrade Mirage and move it to a new server, or are you just looking to move Horizon Mirage to a new server, this article will describe what you need to do.
Network health check is a very useful feature that was introduced with vSphere 5.1 vDS.
What does it do?
The purpose is to test if the VLANs, MTU and Load Balancing settings you defined are actually working. The old way of doing this would be to disconnect all port except one, by either doing a shutdown on the switch port, or pulling out the cable, and then testing, with a VM, if every VLAN still works. This can be a very lengthy process if you have many adapters, but also a necessary step if you want a stable environment.
If you want to know more about how it check the different settings, Joseph Griffiths did a good article on this you can read here: http://blog.jgriffiths.org/?p=877
So why would you ever disable this feature?
Well the health check feature generates a lot of mac table entries as explained in VMware KB 2034795.
An example given is that you have 35 Hosts with 2 Network Adapters each, and 60 VLANs. This will generate (35 * 2 * 60) 4200 mac table entries in your physical switches. And as you can see, this quickly increases. Some switches only has room for 32.000 records or less. Continue reading Should you enable Network health check for your Distributed Virtual Switches
If you need to search your vSphere Datastores for orphaned VMDK files, Luc Dekens made a script that can help you.
Another possibility is to use rvTools.
Today we will look at how to enable REST on phpIPAM. This is an essential part when integrating with vRealize Orchestrator, since REST is an excellent interface for automation.
REST might scare you at first, but don’t loose faith, you will soon enough begin to like it, when you vRealize the power it brings.

Remember one less password, by enabling AD (Active Directory) authentication for phpIPAM.
Quick guide to getting a self signed certificate configured for Apache on Ubuntu 16.04.
All credits go to Justin Ellingwood. There is a link to his article at the bottom of this page. This is just a quick summery of what needs to be done to get SSL working, based on his article.
I do not recommend using self-signed certificates in production, as it does not provide any security what so ever! Deploy a signed certificate from your internal 2-Tier PKI infrastructure. If you do not have an internal PKI infrastructure, your need to get one!
