Why can't I shut down my vSAN cluster?
I ran into a bit of an odd issue today.
After having a load of trouble with a bad boot media on vSAN cluster, I had actually managed to stabilize it and had been running it for a few months.
Today I wanted to shut it down and do some maintenance, dusting , wireing , expansion, that type of stuff.
I followed my usual process of placing the hosts into Maintenance mode with "No Data Migration"
This follows along with the steps I had done many times before in my homelab, but today was different.
In this case I had joined the hosts to a vCenter hosted on another cluster. Previously I would have had the vCenter on the vSAN cluster. I would have shutdown the vCenter, then powered off the hosts.
I was able to place Host 1 and 2 into maintenance, but Host 3 would NOT go into maintenance. The tasks showed that it was waiting for the VMs to be powered off or migrated.
I had already disabled DRS, I had disabled HA. The VMs were powered off. So I figured I would just remove them from inventory... they weren't important to me.
Yet the issue persisted.
So I clicked on Host 3 and checked the VMs
Lo and behold there were 2 vCLS machines still sitting on the host.
So now I am trying to shutdown the vCLS systems , but they are throwing Access Denied errors.
I little bit of digging into the previous article uncovers this note..
"For vSphere 7.0 U1 and later, enable vCLS retreat mode. For more information, see the VMware knowledge base article at https://kb.vmware.com/s/article/80472."
In order to cleanly shutdown my vSAN cluster, I would need to enable a vCLS retreat mode.
The expectation is that with the addition of an "Advanced Setting" I will be able to enable or disable the Cluster Services in the future. The article makes it pretty clear that it is not meant to be run "disabled" so they also offer advice for scripting the change to make it easier to build into a "shutdown" or "startup" workflow.
Hope this article helps, I will update with pictures later as I go through the process.

VCAP - DCV Deploy 2021
I Passed!
Absolutely beside myself. Could not have done it without all the support from my family and my team. On to the next challenge!Tuesday, October 26, 2021
VCP-DCV 2021
I am very excited to have completed my 4th refresh of the VCP-DCV Certification on Oct 20th. I even passed with my highest score ever. 412.
I read it cover to cover and found myself recharged when reading processes that I was familiar with.
Sometimes though, the best way to remember something is to see it done..
So I FIRED UP THE LAB.... and it died... hmmm.. probably should have swapped out that USB boot media when I had the chance. Probably will need to figure out how to recover vSAN with a lost host...
So I FIRED UP THE OTHER LAB ! And I performed an upgrade of the vCenter to 7.0.3!
I tried to upgrade the hosts, but the boot media on these were internal SD cards... error "not enough space for upgrade"
So I powered off and removed one of the blades to get a closer look at the SD cards. 2GB Mirror in the Dell M520 blades. 2GB?! ah , ok , wow.
So I slotted it back in with the intention of addressing that again later, and thats when one of the RAID controllers failed.
I only know that because I tried to refresh vCenter after repowering the blade and realized it was not loading. A quick look at the hosts showed why. The snapshot chain had become corrupt. Trying to commit the snapshots failed. Trying to consolidate the virtual machine, failed.
At least the domain controller survived..... nope. Black screen , restarted, crashed on boot. Direct to Windows recovery options. I could get into directory services restore mode, but no repairs would stick. Dang.
So vSAN lab is down, Dell Lab is down.. This would be a great opportunity to learn some things... but I am short on time.
So, on a prior recommendation from a friend and colleague , I checked out a 7 day trial of CBT nuggets. Fortunately they had an updated course for the VCP-DCV 2021 2V0-21.20 exam presented by Keith Barker. I wanted to see some specific topics so I jumped around a bit, but I did find Keiths style very engaging. More than a few times things didn't go 'as planned', sometimes this was on purpose , other times it was the lab he was using, but it was interesting that some of these things were left in.. because, honestly things do not always go right and it would be wrong to present only 100% success every time.
Ultimately I was able to salvage a domain controller from the vSAN lab, (host 2 is dead in the water though) ...
I built a new vCenter and Domain controller on the Dell kit.
Read some more, watched Keith for a few hours, ran a couple of scenarios on my labs, ran a couple of scenarios on hol.vmware.com.
Then, I got a good nights rest.
I went to the testing center, sat for the exam, second guessed myself a few times. Reviewed the questions that I had "marked" and determined that it was probably more harm than good to go back to them (it was only 9.. and of those 4 were marked because I thought I might need them)
I clicked the button to submit. AND BANG! Screen says congratulations.
Very relieved. I don't have to take it again, I can sit for the VCAP-DCV Deploy now... so it starts all over again..
Wish me luck on November 2nd!

"INVALID" machines after vSAN shutdown.
In some business environments or homelabs it may be necessary to shutdown a vSAN cluster entirely.
VMware has a proper procedure outlined on the documents site.
Shutting Down and Restarting the vSAN Cluster (vmware.com)
Once you have completed your maintenance tasks and fire everything up, you may be startled when you login to each of the hosts and attempt to verify your VMs....
They will probably all display as an "INVALID" status with the GUID Path in the "name" field.
This message certainly caught one of my peers off guard during a recent datacenter update. That quick rush of butterflies in your gut that tells you all of your data is now corrupt.
However, I quickly reassured him that nothing was lost and the issue was simply that all of the hosts were still in maintenance mode.
When the vSAN nodes are in maintenance mode after a reboot, none of the stats are correct since none of the vSAN components are allowed to work together.
If you have powered on all of the vSAN nodes in the cluster and waited a sufficient amount of time for all the vSAN nodes to communicate, the remediation is actually quite swift.
Remove all the Hosts from Maintenance mode.

Congratulations to the vExperts!
Today , VMware released the names of new and returning vExperts for 2021.
vExpert 2021 Award Announcement
I was honored and humbled to be able to stay with this program for my 4th year.
I believe in the VMware eco system and have seen how transformational it has been in my business and I enjoy sharing stories and advice with others on the subject.
I was fortunate enough to join the VMUG in Denver at a great time and found a group of people that understood my language. After being a member for several years, I volunteered my time to hep organize and plan activities for the local groups along with 2 other amazing leaders. The planning and organization of the 2018 Denver UserCon was intense, but attending on the event day was awe inspiring. So many VMware enthusiasts that I spoke with that day thanked us for helping to provide them with so much information about the products and services that could help advance their careers and businesses.
I had to relocate for work to Orlando and immediately sought out the local chapter and immediately volunteered. Once again I found myself connected with passionate leaders and VMware advocates. I was fortunate enough to attend a few in person meetings before the pandemic fully took hold , and I am looking forward to the day that we can get together again.
I am looking for new ways to support and add to the community.
I have started this blog as a way of documenting things that I find interesting and new.
I am looking at the option to livestream some lab sessions.
I answer questions on the Spiceworks forums for those that find themselves in a bind.
Having access to a community that understands your needs and daily challenges is such a profound help and I am hopeful that I give as much as I take.
