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.

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.

Are you tired of wasting 1-2 hours, every time you deploy a template, for it to install all the latest patches?
Why not automate it the easy way?

I just upgraded the vCenter in my test lab, and I got an error after the first part of the process. When it was about to migrate data from the old VCSA 6.0 Server.
I restarted to process but this time is was unable to get information from my source VCSA server. In the log I had the following errors:
