Just provisioned the HPE ESXi 6.7 Update 3 custom OEM image onto some HP DL560 Gen10 servers.
After I updated the servers using update manager and the HPE vibsdepot I ran into problems. Turns out there is a conflict between the VMware provided driver and the HPE provided driver.
The result is that I cannot install all updates to satisfy compliance.
Checking the esxupdate.log file on the ESXi hosts I get the following error:
ValueError: VIBs ELX_bootbank_elx-esx-libelxima.so_12.0.1108.0-03 and ELX_bootbank_elx-esx-libelxima.so_12.0.1108.0-03 have unequal values of the 'payloads' attribute: '[elx-esx-libelxi: 1602.936 KB]' != '[elx-esx-libelxi: 1493.833 KB]'

So VMware released a security advisory (VMSA-2019-0009) about vulnerable VMware Tools.
In short it is recommended to upgrade all VMware Tools to at least version 10.3.10 (Build 10346) which is the newest at the time of writing.
After patching ESXi to the latest build, you might realize that the VMware tools you are left with, after upgrading the tools, in a VM, is 10.3.5 (build 10341) Continue reading How to upgrade to VMware Tools 10.3.10
Recently ran into a HPE Proliant m510 server running vSAN, where vSAN complained that the controller driver for the NVMe disk where too new.
The health error said that the current driver nvme (126.96.36.199.-1vmw.6188.8.131.5202608) was to new and the recommended driver was nvme (184.108.40.206-1vmw.670.0.08169922)
Downgrading is not always a breeze. When going to VMware compatibility guide, the NVMe disk is supported for vSAN 6.7 Update 1, and there are no download links to a specific driver, so how do you get the old driver? Continue reading vSAN – Downgrading NVMe driver in ESXi 6.7 Update 1
I recently installed Powershell Core om Ubuntu 18.04, and after installing the PowerCLI module. I ran into an error.
The error is not an uncommon one, but on Windows the error message makes a lot more sense, so I just wanted to let you know what this error actually means.
The error you might get when you try to connect to your vCenter server using the connect-viserver is the following:
Connect-VIServer : 9/27/18 10:41:37 AM Connect-VIServer The SSL connection could not be established, see inner exception.
At line:1 char:1
+ Connect-VIServer <servername>
+ CategoryInfo : NotSpecified: (:) [Connect-VIServer], ViError
+ FullyQualifiedErrorId : Client20_ConnectivityServiceImpl_Reconnect_SoapException,VMware.VimAutomation.ViCore.Cmdlets.Commands.ConnectVIServer
The only hint here is “The SSL connection could not be established…”
This actually means that you do not have a valid certificate. And if you want to connect to vCenter without a valid certificate, you have to allow this.
You can either change you vCenter certificate to a trusted one, which is the correct solutions or you can ignore invalid certificates, which circumvents all security, but makes it work right now.
Please comment if this was helpful.
Issue with nic driver on HPE servers after updating HPE drivers on ESXi 6.5 and 6.7
I ran into an issue the other day with a vCenter Server Appliance filling up one of its partitions. The partition that was filling up was the /storage/seat partition. This partition holds the postgres SQL database, so the vCenter server was in trouble.
After some digging around I realized that the root cause was a new event error from all ESXi hosts, that was coming at a rapid pace. The errors had started during the last driver and base updates, and only the HPE servers was affected. Continue reading 10fb does not support flow control autoneg
Just had an odd issue today.
A customer had created a Virtual Distributed Switch, but was unable to add his ESXi hosts to the vDS. It said that: “Host is not compatible with the VDS version.”
He was only able to join his version 6.5 ESXi host to a 5.5 vDS. If it was upgraded to version 6.0 or 6.5 it did not work.
There are multiple reports of this online related to upgraded hosts and vCenters. I suspect that it is an issue that you only run into if you do major upgrades without reinstalling ESXi, and since I never do that I have not had that problem before.
The quick solution to this problem is: Continue reading Host xxx.xxx.xxx.xxx is not compatible with the VDS version
I have had an annoying issues at two customer sites now, and I want to share the solution with you.
The problem is that you cannot VMotion VMs to a newly installed ESXi 6.5 hosts running on Lenovo SR650 hardware. The CPU used in the new host is Intel Xeon Gold 6154 Processor, and the old hosts are using Intel Xeon Processor E7-4880 v2. I do not think that the source CPU model is relevant to the issue it could be any supported Intel CPU in the same cpu family.
When trying to VMotion the following error is displayed:
The virtual machine requires hardware features that are unsupported or disabled on the target host:
"""""""""""""* General incompatibilities
If possible, use a cluster with Enhanced vMotion Compatibility (EVC) enabled; see KB article 1003212.
CPUID details: incompatibility at level 0x1 register 'ecx'.
Host bits: 0110:0010:1101:1000:0011:0010:0000:0011
If you then try to enable EVC in the cluster it complains that the new hosts has an issue, and returns this error:
The host's CPU hardware should support the cluster's current Enhanced vMotion Compatibility mode, but some of the necessary CPU features are missing from the host. Check the host's BIOS configuration to ensure that no necessary features are disabled (such as XD, VT, AES, or PCLMULQDQ for Intel, or NX for AMD). For more information, see KB article 1003212.

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
