Clone a Disk by Copying
Data
This function copies data from one virtual
disk to another, converting (disk type, size, hardware) as specified.
vixError = VixDiskLib_Clone(appGlobals.connection, appGlobals.diskPath, srcConnection, appGlobals.srcPath, &createParams, CloneProgressFunc, NULL, TRUE);
Due to a vSphere 6.5 security
enhancement,
VixDiskLib_Clone()
can
no longer clone local disks to remote disks that do not belong to any VM.
Previous releases allowed use of a retained username and password, but now
enhanced security verification is required. The procedure for
VixDiskLib_Clone()
to
make a remote connection is first to get an NFC ticket from the ESXi host based
on the
MoRef
of the VM that manages the cloned-to disks. Then
build an authenticated NFC connection to the host using that ticket. The
MoRef
of the VM must be specified in
vmxSpec
of the remote connection parameter passed to
VixDiskLib_Clone()
. The
VM must be powered off, and the target disks must already exist before cloning,
not necessarily with the same names. Afterwards the VM may be removed from the
inventory with
UnregisterVM
, but it
must remain on the datastore with its cloned virtual disks.
