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. f this happens, the DCO volume must be deleted.

 To recover from the failure of the vxsnap prepare command

  1. Type the following command:

    # 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 vxsnap prepare command again.
