What if the disk controller driver included in my vendor’s ESXi image is not on the vSAN HCL?

Sometimes unfortunately there are situations where a vendor’s ESXi image includes a disk controller driver that is not on the vSAN HCL/VCG (VMware Compatibility Guide). Typically it is a new version of the driver which is supported for vSphere, but not yet for vSAN. In that situation, what should you do? So far … [Read more...]

Is a crossover cable needed for vSAN 2-Node Direct Connect?

I had this question last week around vSAN 2-node direct connect and whether using a crossover cable is still required to be used or if a regular CAT6 cable (CAT 5E works as well) can be used. I knew the answer and figured this would be documented somewhere, but it doesn’t appear to be. To be honest, many websites … [Read more...]

Can’t have more than 255 characters in VM notes using the vSphere (h5) Client?

I had a question about a limit a customer was hitting with the VM notes using the vSphere (H5) Client. They noticed that whenever they got around ~260 or so characters, they could not add any characters beyond that unless they deleted some. After talking to an engineer within VMware I found out that this is indeed the … [Read more...]

VMs which are not stretched in a stretched cluster, which policy to use?

I’ve seen this question popping up regularly. Which policy setting (“site disaster tolerance” and “failures to tolerate”) should I use when I do not want to stretch my VMs?

vCLS VMs not powering on, insufficient resources error

This week I had someone internally me asking about a situation where vCLS VMs were not powering on and an error was thrown stating “insufficient resources”. I had seen this issue before at some point and I knew it had something to do with the VM version and EVC. The details of the error messages seem to … [Read more...]

vSphere HA reporting not enough failover resources fault with stretched cluster failure scenario

Last few months I had a couple of customers asking why vSphere HA was reporting “not enough failover resources” fault in a stretched cluster failure scenario for virtual machines that are still up and running. Now before I explain why, let’s paint a picture first to make it clear what is happening … [Read more...]

How to login to the vCLS VMs!?

I was asked this question this week, how you can login to the vCLS VMs. Now before I share the video, I want to mention that I do not encourage people doing this, but as it is documented and supported I do want to provide a simple “how to” for how this works. If you want to login to the vCLS VM, maybe for … [Read more...]

Did you know vSphere 7.0 Update 1 also has a Skyline Health Check for vSphere Clustering Services?

I did not know this, but yesterday the PM for vCLS reached out to me and informed me that we now have a Skyline Health Check as well for vSphere Clustering Services. The funny thing is that I actually requested this health check to be added after having a discussion on the topic of vCLS with the PM. Very impressive how … [Read more...]
