Content:
An error was detected while reading from a mirror. This error may lead to further action shown by later error messages.

If the volume is mirrored, no further action is necessary since the alternate mirror's contents will be written to the failing mirror; this is often sufficient to correct media failures. 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 indicated. It may eventually be necessary to remove data from this disk and then to reformat the drive.

See the vxevac(1M) manual page.

If the volume is not mirrored, this message indicates that some data could not be read. The file system or other application reading the data may report an additional error, but in either event, data has been lost. The volume can be partially salvaged and moved to another location if desired.

This message may also appear during a plex detach operation in a cluster. In this case, no action is required.
