Derive the history of Unknown (inaccessible) VMs without vCenter Server?

Hello all,

I have an ESXI host with a RAID10 backed local datastore.  On it reside a few VMs.  Some are off, some are on, however there are about 4 that have a status as Unknown (inaccessible).  I inherited this server from a previous IT guy without any documentation, context or history.  I noticed on one of our Synology NAS, there are two iSCSI LUNs, the smaller of the two is in fact connected to one of our other hosts and has nothing of consequence on it.  The larger LUN is not mapped to any of our hosts but has a bunch of Synology Snapshots on it.

LoL, I am wondering, what you think the odds are that those unknown VMs were once running on that disconnected larger iSCSI target?  Is there a way of getting any kind of information as to what those VMs were or at least where their data stores used to reside?

Related can I just right click and remove these unknown VMs, are there any ramifications of doing so?  I am thinking no, but the only reason I have not, is the previous guy left them like this.

Yes, you can just remove them, they are just left over orphaned VMs, with no link to anything, anywhere.

Orphaned VMs, from a datastore which is missing.

The issue is that ESXi cannot read the VMX file, which will contain the datastore UUID reference, to display the configuration of the VM.

You would need to add the datastore back, and it's possible they may re-appear.

You could go digging through the vCenter Server database, and try and find the UUID for the datastore..

Check the Datastore Inventory it may be possible, that the datastore, could be left, as inactive because those objects are still referenced.

Basically poor VMware Administration!!
