Recovering from the failure of vxsnap prepare

If a vxsnap prepare operation fails prematurely, the vxprint command may

show the new DCO volume in the INSTSNAPTMP state. VxVM can usually recover

the DCO volume without intervention. However, in certain situations, this recovery

may not succeed. If this happens, the DCO volume must be deleted.
