We had set up and configured a new Netapp AFF 400. When we tried to add the datastores to ESXi 7.0 host we go the following error:
Key : haTask-ha-host-vim.host.DatastoreSystem.createVmfsDatastore-1660216443
Description : Creates a new VMFS datastore State
Failed – Cannot change the host configuration.
Errors: Failed to update disk partitions for /vmfs/devices/disks/naa.600a09803831462f715d52596146475
I have actually seen this before. The problem is an MTU issue. In our case the VPC in the network didnt have the correct MTU so once fixed that worked. If you see this error then you might want to check the MTU throughout your infrastructure (eg DVS, VMKernels etc)
