Sometimes I find it easier to create a new vCenter server then migrate the old one, and it is a perfectly good solution in many cases.
But annoyingly there is a lot of manual work involved.
One problem is the VM’s and Templates folders. They do not follow the host, so you have to create the folder structure manually and move each VM into the correct folder. Well I am way to lazy to do that by hand, so it’s time to Automate! Continue reading Migrate folder structure from old to new vSphere vCenter
Today I upgraded some HP BL460c Gen9 Blade Servers from ESXi 6.0 to ESXi 6.5. I always reinstall when going from 5.5 to 6.0 or 6.0 to 6.5, so After the server was done installing I found that the FCoE adapters and datastores was missing.
The servers are connected to some HP 3PAR storage using HP FlexFabric 10Gb 2-port 536FLB Adapters.
To regain access to your storage you need to enable the FCoE adapters using the esxcli command.

During an upgrade I got the following error: “A problem occurred while getting data from the source vCenter Server”
And the install log has the following information. Continue reading VMware vCenter VCSA 6.5 Upgrade “Error: queryAaaa ENODATA”

This is meant as a dynamic article for looking up best practice settings for different storage arrays when adding them to VMware.
Why modify the default settings?
When datastores are added to an ESXi host, there are multiple ways that ESXi can leverage the storage. In some cases ESXi will use Most Recently Used path (Active/Standby or MRU) by default, which means that you only leverage one path at the time. This could result in a bottleneck in your storage infrastructure. Many arrays are able to handle Round Robin (Multi path Active/Active or RR) By enabling this will distribute your storage traffic onto multiple adapters, provided that you have multiple adapters.
Other settings can involve how many I/O ESXi should send to a path before switching to another path, or advanced settings that alters the way ESXi handles the storage.
Getting these settings correct will most often result in better performance, but can also help you stay out of trouble that can lead to breakdowns. Continue reading Storage Optimization for VMware vSphere
Today I needed to assign some vCenter tags to some VMs I was deploying using vRealize Automation.
The scenario was that the customer did not want backup of VMs deployed by the vRA test environment, and in production they wanted a specific backup tier.
They are using Veeam backup, so the vRA test environment needed to have a NoBackup Tag, and production needed some other tag, depending on the type of server being deployed.
vRO does not provide very extensive support for these operations out of the box, but vRO 7.2 does come with some sample workflows.
To get started with vCenter tagging you need to configure a vAPI endpoint and a vAPI metamodel.

The new vCenter 6.5 Server Appliance comes with a backup function, but it is not possible to schedule the backup out of the box.
But there are several ways that you can do this yourself. Continue reading VMware vCSA 6.5 Scheduled Backup
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.
