It is not uncommon to get errors after a host update/upgrade you didn’t see before on the host. The following error could be seen as an example of errors with the same cause. The error I did an upgrade of a 6.5 host (installed with HPE ESXi image almost 2 years ago) to the latest HPE ESXi image of 6.7 U3. After final boot the […]
vCenter Tag based VM placement
Introduction The idea behind tag based placement is quite simple. It assists administrators to keep VMs respectively VMDKs on desired datastores, based on tags. For example, a VM is defined to be located in datacenter 1 (DC1). With tag based placement you assign tag “Storage DC1” to all datastores in DC1 and configure a policy that is assigned to VMs in DC1. All wizards in […]
New in 3PAR SSMC 3.6: Topology Insight
A new – and badly documented – feature in StoreServ Management Console 3.6 is Topology Insights. Sounds first like the probably known Maps. But Topology View shows an end-to-end view: VM <–> VMDK <–> Datastore <–> Host <–> Virtual Volume <–> System. Enriched with performance-information! This short post is about this feature and how to get it.
PSP rule for active/standby controller arrays (like Nimble Storage)
First, what does active/standby mean. For this blog post, it means the array hast at least 2 controllers, one presents ALL LUNs to the hosts, the second controller presents NO active LUNs path to the hosts. Just in case of a manual or automatic failover, the second controller takes-over ALL LUN-presentations – and active paths. Examples of such arrays are: [very old one] HP MSA 1000 HPE Nimble […]
Bad deployment and storage size estimation in vCenter migration wizard
When migrating vCenter from Windows to Photon appliance, wizard estimates deployment (vCPU and memory) and storage size – based on data of migration assistant, running on source vCenter. It happens quite often, storage size is much higher than used in Windows vCenter. When do researching, free up disk space is a suggested task. Most often this does not work properly. Last vCenter I had to […]
VCSA 6.7 U3 sends no log data to syslog server
Recently a customer noticed that all his vCenter Server Appliances (VCSA) running 6.7 U3 (6.7.0.40000 respectively 6.7 build 14368073) do not send any data to syslog server any more. Rebooting VCSA or restarting service gets the system to send data again – for a few minutes. Changing syslog-settings in Appliance Management (VAMI, Port 5480) also brings VCSA to send logs for a few minutes. VMware […]
Implement VMware Skyline for vSphere
In this post I will describe how to install VMware Skyline by deploying Skyline Collector in your datacenter. If you don’t know, Skyline is a cloud-based proactive support platform. At the moment of writing, support for these products are available: vSphere, NSX, vSAN, vRealize Operations and Horizon. You should also know, that when you have active Production Support or Premier Services subscription, Skyline is included! […]
Cannot add 3PAR storage provider because of certification error
Normally when using a self-signed certificate you get a warning. It is also normal to accept the certificate to continue your task. These days I wanted to register a 3PAR system as storage provider in vCenter. Because of a certification error, this could not be accomplished. In this post I describe how to solve – at least my – problem.
