Failure of vxsnap prepare
If a vxsnapprepare 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, use the following command to delete the DCO volume:
# vxedit [-g diskgroup] rm DCO_volume
Alternatively, the DCO volume is removed automatically when the system is next restarted.
When the DCO volume has been removed, run the vxsnapprepare command again.
