Adam - Any insight into this issue? Could it be a configuration that is not allowing hot-add of disks to this VM?
I doubt the non-persistent option is causing this but I've been surprised before. Luke were you able to add dependent disks to the VM but not independent-nonpersistent ones? Are you able to successfully do this through the VC client but not through cfme?
Hi Adam, so I think I figured this one out, I was adding a nonpersistent dependent disk which is not possible in vsphere, perhaps this option should be changed in cfme to match? If nonpersistent is chosen perhaps we could set dependent to 'NO' + grey out the option?
I have since taken another look at this and found it's possible to add a nonpersistent dependent disk to a powered of vm through cfme. The disk mode shows as blank in vsphere but in cfme we see it as 'nonpersistent', so its only powered on vms that I can't seem to add nonpersistent dependent disks.
So I was able to add a non-persistent disk through CFME when the VM was powered off but VMware was really not happy about it. I couldn't power-on the VM and I couldn't delete the disk without first setting a different disk mode. The only supported disk modes for the VirtualDiskFlatVer2BackingInfo backing type are: Dependent, Independent-Persistent, or Independent-Nonpersistent The other types are listed here https://www.vmware.com/support/developer/vc-sdk/visdk400pubs/ReferenceGuide/vim.vm.device.VirtualDiskOption.DiskMode.html but I suspect the rest are used for implementing snapshot sparse/delta disk files. I'll take this ticket to implement some validation in the vmware provider code but we should also change the UI to show a dropdown where the user can select from Dependent, Independent-Persistent, or Independent-Nonpersistent just like the VC client has. Thanks Luke great find!
