If this error occurs often, but never leads to a plex detach, there may be a marginally
defective region on the disk at the position shown. It may eventually be necessary to
remove data from this disk (see the vxevac(1M) manual page) and then to reformat
the drive.

A notice message indicates that an error has occurred that should be monitored. Shutting
down the system is unnecessary, although you may need to take action to remedy the
fault at a later date.
