Ok so final update on what is working... the trick is to upload the vmdk files to a folder.. then use the datastore browser to copy them in the VM folder and use the copies when configuring the VM. i guess it is some kind of permission issue that is bypassed when creating the new files (copies)... its strange very few people had this issues though.. anyway... cheers everyone

as an update.. i tried to copy the vmdk file to a folder outside of the vm folder (i guess it automatically copies the .vmdk and flat-vmdk (?)) and it managed to get a screenshot... its strange as no other VM does this but i will experiment a bit on this... and see if it works...

Unfortunately this does not seem to be the case.. i created a new VM with the exact same settings and used DSTEST as the name. Still get the same error... I used the latesr ARPL image and other than that the rest seem to be standard items for ESXI (all disks are SATA)... Is therea any other idea on how i could start to trace the issue?

Hello i am having a similar issue on ESXI 7 and DSM 7.1.1 / DS362xs VM which brings up the following message: Create Snapshot Key: haTask-10-vim.VirtualMachine.createSnapshot-1705 Description: Create a new snapshot of this virtual machine Virtual machine: DS State: Failed - A specified parameter was not correct: spec.deviceChange.device Errors An error occurred while saving the snapshot: One of the parameters supplied is invalid.

An error occurred while taking a snapshot: One of the parameters supplied is invalid. i can find nothing on the internet for this.. any help appreciated

I have the exact same issue in a similar setup.. Snapshot produces the following error regadless if it is powered on/off: Create Snapshot Key: haTask-11-vim.VirtualMachine.createSnapshot-390 Description: Create a new snapshot of this virtual machine Virtual machine: DSTEST State: Failed - A specified parameter was not correct: spec.deviceChange.device Errors: An error occurred while taking a snapshot: One of the parameters supplied is invalid. I googled the state and error description but results are very limited.. any idea on what to test would be more than welcome...
