If you change from OS-based naming to enclosure-based naming, simple or nopriv disks may be put in the error state and cause VxVM objects on those disks to fail.

You can use the vxdarestore command to handle simple and nopriv disk failures that arise from changing to the enclosure-based naming scheme. You do not need to use this command if your system does not have any simple or nopriv disks, or if the devices on which any simple or nopriv disks are present are not automatically configured by VxVM (for example, non-standard disk devices such as ramdisks).

See the vxdarestore(1M) manual page.
