COMSTAR logical units are often created on top of ZFS volumes (zvol). The following procedure describes how to backup and restore zvols or perform incremental restore on LU backend ZFS volume.
This example shows how to temporarily unload the LU from a framework, perform the ZFS rollback to restore the previous ZFS snapshot and then re-enable the COMSTAR LU.
