ESXi host mappings unexpectedly removed from SAN
A storage administrator mistakenly removed the VMware ESXi host mappings which were still mapped and being used in Production environment from the SAN. This of course impacted live services and I was the lucky person on call. I’ve posted this because I’d hoped that simply readding the host mappings on the storage might resolve the…

Reset root password for VMware vRealize Operations appliance
I’ve needed to reset the root password on VMware vRealize Operations appliances on a few occasions and although the official guide from VMware contains very helpful information, it wasn’t easy enough to follow for some of my colleagues who weren’t proficient in Linux or text editors. The purpose of this post is to include screenshots…
vMotion failing with “The VM failed to resume on the destination during early power on. The source detected that the destination failed to resume.”
VMware KB 59665 advises to reboot the VM to clear any locks but I found this wasn’t required. I completed a Storage vMotion of the VM Configuration file to another datastore and the VM was then able to vMotion successfully which meant no downtime for the Production servers! Remember to move the VM Configuration file…
Reset vmhba storage Fibre Channel adapter on ESXi host

Use PowerCLI to find which VMs restarted after a HA protected host failure
One of my hosts in a HA protected cluster crashed and I usually use vRealize Log Insight to retrieve a list of VMs which have been restarted on other hosts but in this instance, the host in question didn’t seem to have been logging correctly and I wasn’t getting any results back. I found a…
Supermicro E200-8D for my home lab
Finally got my hands on a Supermicro E200-8D and now have a bit more compute resource for my home lab. It’s a well known micro server in the vCommunity but the full specs are here: https://www.supermicro.com/en/products/system/Mini-ITX/SYS-E200-8D.cfm It only came with 1 x 32GB memory but has four slots so once I fill these, it’ll have…

Time to get Certified – VCTA DCV 2020 (1V0-21.20) exam experience

Hide VMs in the Hosts and Clusters view in the vSphere Client
This is a great setting to change for Administrators that spend most of their time in the Host and Clusters view managing hosts rather than the VMs. It’s a feature that was easy to change and quite well known in the old fat client but seems to get forgot about in the new HTML5 vSphere…

Workaround for the vCenter 7.0 ‘Failure to deploy OVF package’ bug when deploying VMs from a Content Library with a Proxy enabled
I was unable to deploy VMs from my Content Library after upgrading vCenter to 7.0.
