Nutanix: Error – Foundation service running on one of the nodes

In the past I had two different scenarios, where an running foundation process got me some errors. The first one was, that I could not run LCM and the other one was that I could not upgrade Foundation via PRISM, like you can see on the screenshot: Under normal operations, the foundation service is stopped […]

Nutanix: Clean up system partition /home/nutanix

I have seen many AOS update pre-checks failed, simply because there was not enough space left on the system partition.This looks like this (“Not enough space on /home/nutanix partition”): Meanwhile there is also a regular check within PRISM, which will give you a warning if a CVM reach more as 75% utilization: This happens usually […]

Nutanix: LCM error – lcm_family attribute missing

During the last month I had two clusters, where the LCM process didn´t start because of a missing lcm_family attribute for some of the nodes. Unfortunately I can not find the error screenshot from PRISM, but the LCM error message contained lcm_family. On each Nutanix node you find a hardware_config.json at /etc/nutanix with a bunch […]

Nutanix: Node stucks in Phoenix boot loop after LCM run

The Life Cycle Management within PRISM is an awesome framework to automate all kind of hardware updates of your Nutanix nodes with just some clicks. LCM in general has become pretty stable since AOS 5.5 and only rarely needs some support assistance. One situation I have seen now multiple times is, that a Node stucks […]

Nutanix AHV: How to get rid of orphaned 3rd party backup snapshots

Like with any other hypervisor you can also end up with orphaned snapshots in combination with third-party backup tools on AHV.

Horizon View: Black screen after vSphere 6.5 upgrade (PCoIP / Blast)

In a recent project, I just run into the problem that a vSphere upgrade from 6.0U2 to 6.5 broke the possibility to connect to the existing Horizon View VMs via PCoIP (HTML5 / Blast also affected). The users just got a black screen after connecting to the desktop pool. After switching them to RDP as […]

VCSA 6.5 update fails with “vix error codes = (1, 4294967294)”

Last week I performed a VCSA upgrade from 6.0U2 to the latest 6.5 version. Already in Stage 1, where I needed to connect to the source appliance I got the error “A problem occurred while getting data from the source vCenter Server” from the installer (like you can see on the screenshot). The attached log […]

Unable to login to the vSphere Web Client after VCSA 6.0U1 upgrade to 6.0U2

After an upgrade of a VCSA 6.0U1 to 6.0U2, I was unable to login to the vSphere web client. Also the login screen was a little bit messed-up like you can see on the screenshot below. When I entered a login name and a password it directly showed User name and password are required, like […]

Configure a HTTPS proxy for vCenter VAMI updates

I just needed to update a customer’s vCenter server from 6.0U1 to 6.0U2. As I didn´t have access to the vSphere cluster where the vCenter VM itself was running, I tried the update option via the VAMI interface. The vCenter was unable to directly connect to the internet but I got a proxy URL from […]

Removing multiple VMs / entries from the VMware Horizon View Composer Database

Manual modifications in the VMware Horizon View ADAM or Composer Database can be a very annoying task. Last week a customer had a serious problem with a View 6.2 installation, which led to many left over entries of linked clones in the Composer SQL database. In the KB 2015112 VMware lists all relevant tables and […]
