This virtual machine uses hardware version 1 error this morning

I signed into VCSA this morning and noticed a few VM’s powered off with (inaccessible) added to their VM name.

When I check the summary of the VM, it shows the following message:

This virtual machine uses hardware version 1, which is no longer supported. Upgrade is recommended.

My hosts are VMware esxi:

* VMware ESXi, 6.0.0, 2494585

and my VCSA is:

* vSphere Client version 6.7.0.20000

When I look at the inaccessible VMs and view the Update Manager –> Upgrade VM Hardware to match host, I don’t see anything listed in the update manager.

I’m not sure if this has anything to do with it, but looking at the summary page for the vcenter VM I see:

* Guest OS:Linux 4.4.152-1.ph1 VMware Photon 1.0 Photon VMware Photon 1.0
* Compatibility:ESXi 5.5 and later (VM version 10)

​

I’m a bit confused on what I should do. I’m glad that none of my critical VMs experienced this issue. From reading online, it seems I may have to re-create the affected VMs and reattach the disks?

Has anybody experienced this error before?

​

Thanks

**Edit:** After investigating this afternoon, it seems one of my storage switches failed, hence the issues with not being able to reach a datastore and power on two VMs.

    You sure you don’t mean 10? I’ve never seen the error, (Inaccessible) means the storage for the VM is missing. Did you just update ESX/vCenter?

    A compatibility upgrade you right click on the VM and it’s in the list somewhere.
