Upgrading a vSphere Host Using vSphere Update Manager (vSOM) Installing VMware vSphere Update Manager 5.5 on a Microsoft Windows platform. Fix - No coredump target has been configured. Once I built my ESXi 5.5 hosts in my test lab and added them to my vCenter environment, they both had a yellow warning prompt stating: “No coredump target has been configured.
Host core dumps cannot be saved” The good news is I was able to fix this, so I thought to document the solution in case anyone else has the same issue. All the details are below… Situation In my situation, I was both my hosts have ESXi 5.5 installed on a USB flash drive (each 32GB in size), which may have been the cause of the issue. Just so we are all on the same page, the warning message I was seeing on the host was: Solution To resolve the “No coredump target has been configured” error, complete the following steps: Error: No coredump target has been configured The solution above was successful for one of my ESXi hosts, however on the second host when I ran step 2 to find the active diagnostic partition, one was already configured… yet I was still getting the No coredump target has been configured error.

Yes, this is an old topic, but it’s still too evident today…. This should be in your “just do it” category. It’s the awful Certificate warning displayed in your Powershell session when you connect to a vCenter server (or direct to a ESXi host) that hasn’t had the default SSL certs replaced. For whatever reason (I don’t judge) it can be a PITA for busy admins to bother sorting and replacing the SSL certs, or perhaps they are “CLI-shy” and just don’t see it.
It’s the PowerCLI equivalent of this; (which is almost always is installed/ignored) For me though, if you can’t fix it, you should at least SUPPRESS it and not fill that session up with yellow clutter and delay your script connection times. The setting to change this is stored in the PowerCLIConfiguration context and current settings can be displayed using; Using PowerShell to create a Virtual Machine Inventory in VMware and Export it to a CSV File.

This post continues along that journey with a focus on vCenter, plugins, ESXi hosts, and gotchas within a vSphere 5.5 environment. Hope it helps! The first thing I wanted to look at was my vCenter plugin URLs. These are the addresses used to talk with the plugin. If they were hard coded using an IP address, they’d need to be updated to either a new IP address or a DNS name. The fastest way to dump all of the URLs for my plugins was to crank out a quick PowerCLI script. Most of them were fine, or pointed towards the local server itself, but a few – such as my vCenter Operations Manager plugin – would need to be fixed. vCenter 5.1 upgrade. vSphere 5.5 - Part 2 - vCenter Single Sign On (SSO) 5.5 (inc U1) Install - VMadmin.co.uk.

Cluster warning for ESXi Shell and SSH appear on an ESXi 5.x host. Unable to bond Etherchannel on ESXi 5.5. I couldn't seem to get an etherchannel working properly on a ESXi5.5 host, I'm not using vcenter and was attempting to aggregate the links to a Cisco 3750.
I referred to the kb article below, I configured IP hash on the ESXi host, set SRC-DST-IP aggregation algorithm on the switch, and disabled LACP, however when I disabled LACP per the guide, I lost connectivity altogether to the ESXi host, although all of the ports in the etherchannel showed '(P)' and actually correctly established a bundle. If I re-configured the etherchannel to enable LACP, I could ping and connect to the host, however all of the ports in the etherchannel are showing '(I)' which means operating independently. So I presume its the host configuration rather than the switch configuration which is incorrect but can anyone advise?

Every found your self with an issue and spending hours trying to find a solution while none of the Google (or bing) search(find)engine results fixed you’re problem?
Well I did just this today. Trying to update our VMWare clusters I noticed some VM’s not willing to vMotion to another node and that the task stalled at 14%. With off course the all clarifying error: “Operation timed out” and from Tasks & Events “Cannot migrate <VM> from host X, datastore X to host Y, datastore X” My solution: It turns out that, in my case, there was a vmx-***.vswp file left over from a failed DRS migration. During a DRS migration, because the VMX is started at both nodes, each VMX process create a process swap file, with or -1 of -2 in the name. So when you browse the datastore you’re failing VM is located on, and you open up the folder of the VM, you should see those two vmx-***.vswp files, as presented in the image below.
The oldest one is most likely the one you need to delete.
