Had an annoying error today. Was updating an ESXi image for use with AutoDeploy. When I reinstalled the hosts they would not join vCenter. My workflow removes them from vCenter in the process, but they were unable to rejoin, and I could not add them manually either.
I got two error:
When selected the license in the add host wizard I got this error:
Cannot decode the licensed features on the host before it is added to vCenter Server. You might be unable to assign the selected license, because of unsupported features in use or some features might become unavailable after you assign the license.
I pushed through, but when the task reaches 100% it gave another error:
License file download from <servername> to vCenter Server failed due to exception: vmodl.fault.SecurityError.
Well to cut a long story short it turned out to be a time issue. Some of the serveres was not allowed to talk to the NTP servers. and their time had drifted. vCenter was located on one of these serveres, and its time was 5-6 minutes behind the ESXi servers that I was trying to join.
The NTP connection issue was corrected. Time was checked on all servers.
Hope this helps someone.
So I was installing some Fujitsu Primergy RX2530 M4 servers today, and since I mostly work with HPE and Lenovo servers I had lookup the optimal BIOS settings to run ESXi 6.5.
This is what I came up with. From the default settings I only changed a couple of things that I found important. Continue reading Fujitsu Primergy ESXi Install Server Notes – BIOS Settings
just updated a vRealize Operations Manager server today from 6.0.2 to 6.6.1, and unfortunately I got an error during the fourth step of nine (4/9):
Failed The PAK action "apply_system_update" script "/usr/lib/vmware-vcopssuite/python/bin/python updateCoordinator.pu -p " failed
As I was in the middle of a vCenter upgrade and some other stuff, that was a little annoying, and I could not really find any articles on the particular problem, so I did some digging around in the appliance, and it turns out that it is not pleased with the certificate on the appliance.

Today a college of mine was asked by a customer if it would be possible to only allow specific host to send logs to VMware vRealize Log Insight (vRLI).
And as it is running on a Linux platform iptables is built in, so I figured why not?
iptables is a in kernel firewall built in to almost any Linux distribution.
Why would you limit who can send logs to your vRLI. This is not something that I hear many customers ask for, but I can certainly understand why you would not want any host or user without permission to spam you logs. And even though the filtering in vRLI is very good, you could potentially run out of disk space, and miss log that you actually wanted. Also it would be possible for an attacker to disguise his whereabouts with generated false logs. This would not be a foolproof method to avoid this, as I can easily think of a couple of ways to accomplish this anyway. Continue reading Allow only specific hosts to log to vRealize Log Insight
Here is a list of things that you might want to do before you upgrade your vCenter from vCSA 6.0 to vCSA 6.5.
Postgres table owner
First check you postgres database. For some reason the table owner is often wrong. Thanks to black88mx6 There is a way to check this, and also to fix it. Remember that anything you see here is executed at your own risk. An important step to perform before upgrading is taking a backup/snapshot of your vCenter VM, and any related components, so that you will be able to recover from a failed upgrade.

After upgrading VCSA from version 6.5 to 6.5 Update 1 you might experience a problem with Task Names and object Descriptions. Names are not “resolved” to its human understandable name, but instead they are written as a API object name.
For instance a host profile compliance check would normally be “Compliance check” but is instead written as “profile.ComplianceManager.check.label” or a VMotion is written as “Drm.ExecuteVMotionLRO.label”

Today I upgraded a customer to ESXi 6.5 Update 1, but unfortunately some of them ended up purple screening at reboot after they were updated.

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”
