Found invalid object errors on storage volumes

Found invalid object errors on storage volumes

I want to share the solution of flooding errors I had after an vSphere upgrade. Errors are probably not connected to upgrade. The problem I got flooded by errors for VMFS datastores in log files.

vCenter Tag based VM placement

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

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)

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 […]

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.

VCSA 6.7 U3 sends no log data to syslog server

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 […]

Cannot add 3PAR storage provider because of certification error

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.
