Cause

This issue occurs because the ESXi host incorrectly classifies .vmdk files with name beginning with core as core file instead of the expected disk type.

Resolution

This is a known issue affecting VMware vCenter Server 5.5.x.

This is resolved in VMware ESXi 5.5, Patch Release ESXi550-201410001. For more information, see  VMware ESXi 5.5, Patch Release ESXi550-201410001 (2087358).  Download this patch from My VMware.

To work around this issue, use one of these options:
  • Clone the affected virtual machine by changing the name so that the name does not begin with the word core
  • Use the vmkfstools utility to rename the virtual machine's disk(s) so that names do not begin with the word core. For more information about the vmkfstools utility, see Cloning and converting virtual machine disks with vmkfstools (1028042).

    Note: Using vmkfstools commands can potentially make the virtual machine unusable, so it is recommended to contact VMware Support for assistance.
