I have taken over administration of our VI3 and encountered this message: "failed to extend disk the called function cannot be performed on partial chains please open the parent virtual disk" when I attempted to expand a virtual disk on a VM that has a total of four virtual disks. The four virtual disk files are: disk-000001.vmdk, disk_1.vmdk, disk_2.vmdk and disk_3.vmdk. There is another vmdk file with the name of the VM itself and thought that was the parent but encountered this message instead:failed to extend disk one of the parameters supplied is invalid 1. Based on the setting information for this VM the disk name is disk-000001.vmdk. There are no snapshots for this VM and it was not running when I attempted to expand the virtual disk using vmkfstools.
Suggestions would be appreciated.
