Upgrading to VMware vSphere 6.7

It’s finally out! vSphere 6.7 is the next major release of VMware’s virtualization software. I’ve been using 6.7 through the vSphere Beta Program and testing even newer features in my current role. I am here to talk to you about planning your vSphere upgrade and some planning and considerations you should have when going to the latest release.

Reconfigure HA - The object 'vim.Datastore:datastore-XXXX' has already been deleted or has not been completely created

Another lovely Friday starting off with strange issues, when taking a host out of standard maintenance we noticed that HA would not reconfigure, and kept saying The object ‘vim.Datastore:datastore-1131’ has already been deleted or has not been completely created. This was strange because no other hosts had this issue. I proceeded to follow standard troubleshooting steps, reconfigure HA…same issue….disable HA for entire cluster and re-enable…..same issue…whoops thats not good! First step, check what luns are available to the cluster.

vCenter 6.5U1 Update Issues with VCHA Advanced Deployment

vSphere 6.5U1 was released on July 27th. This is an incremental update a lot of people wait for before upgrading from a previous version. I have been lucky to have been running on vSphere 6.5 for quite some time and have been enjoying it very much. Obviously we never upgrade production first, if we can help it. I decided to attempt an upgrade on one of our QA vCenters that was deployed using the VCHA Advanced workflow.

Using PowerCLI to Set vCenter Permissions on Datacenter

I have been working on doing a vCenter Consolidation Project. This has meant recreating multiple permissions groups. I couldnt find an easy way to apply permissions at a datacenter so I updated this script to be used. Pre-Requsites VMware PowerCLI Link to Script Set-vCenterPermissions.ps1 permissions.csv Preparing to Execute the Script The script is pretty straight forward, just need to update columns in the CSV such as Datacenter, Group and Role.

vSphere 6.5 - Updating Appliance configured with vCenter HA

Warning: A few others and myself have noticed that when updating a VCHA Cluster to 6.5U1 it resets the hostname to localhost.localdomain stopping vCenter Web Client from Loading. It seems to be isolated to Advanced Deployments and not Basic. I would recommend destroying your VCHA Cluster, updating, then redeploying in this scenario. Warning2: It also seems that if you try to redeploy VCHA Advanced after an upgrade, it still resets the hostname, I have a case opened and will update here as neccessary.
