When a VM is rebooted in OS, it keeps powered on at ESXi host during the whole boot process. Sometime it would be very useful when a OS reboot triggers a cold boot. In this post I show how to cold boot VM by guest reboot. Cold boot is like to power cycle a computer. A VM needs to get through a power off state […]
PowerShell error when accessing PowerShell gallery
Most often installing PowerCLI is no problem. Sometimes there is a PowerShell error when accessing PowerShell gallery. Like now: Just wanted to install PowerCLI onto a new Windows 10. When running the command find-module vmware* I get this error(s): Fortunately I found a solution quickly here. Problem is related to security protocols used in PowerShell. Check current protocols by running: My Windows 10 showed this […]
Add HPE servers to InfoSight
HPE InfoSight is a cloud based IT operations management platform which uses artificial intelligence (AI) for data/metric analysis. So it is able to proactively find issues in individual environments before they actually causes a problem. Currently it is possible to connect these HPE products to InfoSight: Nimble Storage, 3PAR/Primera Storage, SimpliVity HCI, Servers. This post shows how to add HPE servers to InfoSight. For this, […]
Get HPE Primera/3PAR metrics in vROPs 8.x
This post is about two cool and powerful products: VMware vRealize Operations Manger (vROPs) and HPE Primers/3PAR and how to combine them. This post includes current versions of both. Good and a bad news about costs: Bad first: vROPs free for a short period of time as trial. Good one: HPE Plug-In is free! Version 3.7 of HPE Storage Plug-ins for VMware is the first […]
Replace machine certificate in vSphere 7
Compared to posts that describe the same task in older versions, this will be a rather short one. Specially replacing vCenter certificates was getting more and more easier during versions. It has never been that easy! In vCenter 7 we just have one certificate to manage. Solution Certificates are gone, respectively are deprecated in 7.0 . You can also see in CLI certificate-manager. See welcome […]
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. Errors in /var/log/vmkernel.log: 2020-01-29T14:06:00.311Z cpu8:2099233)WARNING: Fil3: 8175: Found invalid object on 59c4eb22-52356382-42b5-5cb90195e9c0 expected 2020-01-29T14:06:00.311Z cpu8:2099233)Vol3: 3374: Failed to get object 28 type 3 uuid 59c4eb22-52356382-42b5-5cb90195e9c0 FD 8029c4 gen 3 :Not […]
Intel CIM error after update/upgrade ESXi host
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 […]
